bognition•6mo ago
Back in school I was often told the lead pipes in Roman aqueducts likely played a key role in the fall of Roman. We know lead is a poison with negative long term effects on cognition.

The aqueducts were also responsible for Romes ability to proliferate and grow. Lead was both a blessing and a curse.

I wonder what future generations will say about our highly enriched and processed diets. Calories have never been cheaper and food is ubiquitous. However I believe our food is playing a huge role in our degraded health.

It’s not surprising that most studies looking at the consumption of unprocessed food, fresh fruit and vegetables show benefits to our health.

The challenge is how do we get this food in the hands of those who need it cheaply and without sacrificing the nutritional (and microbial) content.

papercrane•6mo ago
The lead pipes theory is mostly just pop-science. Romans were likely getting more lead exposure from using lead cooking vessels and utensils.
edwardbernays•6mo ago
So is the idea that widespread lead exposure led to the decline of the Roman empire largely pop science? Are you saying that's not accurate, or that the source of the lead exposure is miscounted?
Quarrel•6mo ago
Yes, that is the modern understanding. Widespread lead exposure had very little / nothing to do with the decline the Roman Empire.
Isamu•6mo ago
Plus to prove the lead connection you have to discount the centuries of Roman dominance and growth during which lead exposure was common.
wredcoll•6mo ago
This is a much better point. It's not like there were more lead pipes during the decline than the rise.
edwardbernays•6mo ago
Wouldn't there necessarily be more lead pipes at the peak and post-peak? Assuming that pipe-building was some non-linear function of dominance, which seems a fair assumption, we would start with 0% pipes at 0% rome and asymptotically close to 100% pipes at the asymptotic 100% peak rome. Is this a bad assumption, or is it basically just pedantry?
wredcoll•6mo ago
It would be more about lead pipes per capita, possibly as rome itself grew wealthier from conquests they added more and more piping, but it would be hard to relate this to any specific moment in time.

Presumably the wealthy elites had their pipes installed first anyways.

throawaywpg•6mo ago
"Decadence" likely had nothing to do with the Roman Empire's fall. That theory is based essentially on propaganda, designed to absolve them of blame.

The lead pipes had too much calcification, and not much lead would have leached out. But the Romans did use lead acetate as a sweetener, so they were adding lead directly to many (most?) of their meals.

yawboakye•6mo ago
there are many ways to account for the fall of the roman empire, and everyone chooses their favorite (usually depending on where their interest bends). for example, it could be explained by the increased usage of mercenaries in the roman army. i like this theory because the fall was brought by losses to renegade forces. it could also be explained by bad leadership.
didgeoridoo•6mo ago
Plus literally “flavoring” their wine on purpose with lead acetate.
MengerSponge•6mo ago
And that was the first and last time that no-calorie sweeteners had deleterious population-level effects
lotsofpulp•6mo ago
High calorie sweeteners have deleterious population-level effects.

Is there any evidence that modern low calorie sweeteners have deleterious population-level effects, and what are they compared to high calorie sweeteners?

cjbgkagh•6mo ago
Anecdotally I get gut dybiosis (microbiome imbalance) that notably only occurs when using artificial sweeteners and stops when I stop taking it, I’ve talked to many others who have noticed the same thing. Gut dysbiosis can cause chronic systemic inflammation which is rather bad for the body, not sure if it’s worse than the sugar it replaces, but it shouldn’t be assumed that the problem is solved by low calories. I think it’s important to limit both, preferably to near zero.
hinkley•6mo ago
Sugar alcohols are especially bad for this. I fried my GI one year and it was largely down to developing a gum chewing habit at a time when sugar alcohols were in almost all gum brands. You can’t process them, but bad gut bacteria can.

cjbgkagh•6mo ago
Lower intelligence would likely surface as hedonistic behavior which is probably hard to distinguish from decadence. Decadence and hedonism were constantly being complained about long before the eventual fall.
evertedsphere•6mo ago
> Lower intelligence would likely surface as hedonistic behavior why do you think so
throawaywpg•6mo ago

hinkley•6mo ago
Violence in the US declined as children born around and after leaded gas was banned reached the average age of first offense. It’s quite a line.
cjbgkagh•6mo ago
You're going to have to explain your point to me, or perhaps you misunderstood my own.

My point is that while it may have been unclear to the Romans as to the cause of changes in behavior they did notice a change and did complain about it a lot. I accept the premise that lead poisoning leads to lower intelligence.

hinkley•6mo ago
What we know now is that lead’s effects are more pronounced as developmental issues. A little lead exposure as a child can lead to a violent temper. So once children were not born into a low grade cloud of lead contamination, they were set up for fewer mood disturbances as teenagers and young adults. Feeling like violence is your best avenue for conflict resolution leads to crime. So the change wasn’t over night, it was over 20 years.

I expect that whatever effect was going on in Rome if there was one, which seems to be up for debate, counted on pregnant women exposed to lead via alcohol and acidic foods, neither of which young children would normally encounter. Meanwhile lead dust from exhaust got -everywhere-, and paint a lot of places.

cjbgkagh•6mo ago
I still think you are agreeing with the implied and later stated accepted premise that there is a correlation and it’s not always obvious, I’m still unsure as to what it is you are trying to add.
JumpCrisscross•6mo ago
> Violence in the US declined as children born around and after leaded gas was banned reached the average age of first offense

My pet hypothesis for the generation born after in the mid postwar era having been a general scourge on America is that we had a population boom amidst lead.

paleotrope•6mo ago
Hard to square the fall with lead poisoning when the leadership after the 3rd century hardly even bothered to go to Rome at all.

It's too easy to point at the Claudians as the beginning of the fall. In a way, the "Real" Roman empire began to fail once Augustus took over.

declan_roberts•6mo ago
Not to mention the fact that their pipes immediately become mineralized, and very little lead leeches in cold water.

Headline science has a way of sticking around for a long time.

hungmung•6mo ago
Also...Roman plumbing was constant-flow. Lead in water is mostly an issue when it gets to rest in the pipes for a while, then when somebody turns the tap on they get water that's had time to absorb the lead. Since Roman plumbing had no taps though and was just running constantly, the amount of time the water was exposed to the lead was pretty minimal.

dathinab•6mo ago
also lead flavoring

lead tastes sweet, sugar wasn't cheaply & widely available, honey is expensive etc.

and knowledge about lead poisoning was not really a think AFIK

at the same time lead pipes tend to gain a crust of chalk over time (depending on chalk content of the water) which mostly defuses their danger. Like you will find some very old houses with lead tape water pipes in the EU today but if you test their tape water you won't find (much of) an issue due to 1) the chalk 2) the water not staying long in the pipe if it's e.g. a 4 apartment house.

Here's Vitruvius in "De Architectura" claiming it's common, easily verified knowledge: https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Vitruvius...

Of course, him mentioning "Don't do this" suggests that lead water pipes into the home were common enough to need a warning against.

dathinab•6mo ago

sadly, they still are today sometimes, in areas with a lot of 125+year old infrastructure :/

Which continued pretty much into the modern age. Nothing specifically Roman about it.
giantg2•6mo ago
"Back in school I was often told the lead pipes in Roman aqueducts likely played a key role in the fall of Roman. We know lead is a poison with negative long term effects on cognition."

I highly doubt there was much effect from the pipes. They would quickly be sealed in mineral scale. Cups or utensils - maybe, but would be more about specific important people using them rather than being widespread.

MengerSponge•6mo ago
Wine (and grape juice) was cooked in lead vessels, which generates Lead(II) Acetate aka Sugar of Lead. They lead poisoned themselves coming and going.

https://en.wikipedia.org/wiki/Lead(II)_acetate

hinkley•6mo ago
Pre enlightenment Europe also saw cheap wine being sweetened with a lump of lead suspended in wine barrels.

Around the World in Six Glasses will tell you that tea replacing wine lead to Progress in Europe because they weren’t drunk all day but I wonder how much was inebriation and how much was lead exposure.

MengerSponge•6mo ago
Smells like a little of column A, a little of column B.

Beer was also widely prevalent, right? Even if it's just small beer (<3%ABV), it's not exactly making you smarter. It's hard to hit the Ballmer peak, after all

hinkley•6mo ago
Beer was their water treatment plan. You drank watered down alcohol as a way to avoid waterborne illnesses. Tea is boiling water which we still use to this day to deal with the water supply being contaminated.
underlipton•6mo ago
It should be noted that juice is a highly-processed food. It concentrates the sugar, vitamin, mineral, and water content of a plant while removing the fiber.

As to your last question, part of it may be rethinking the profit motive in food production. Food waste to keep prices high is a huge issue.

Etheryte•6mo ago
The lead pipe thing is one of the best known urban legends that's both completely false and also constantly making rounds on the internet.
SapporoChris•6mo ago
Not sure where you get completely false. Like most urban legends it's a little truth and a lot of falsehoods. Lead pipes are a known health hazard. Lead pipes didn't lead to the fall of the Roman Empire.
Etheryte•6mo ago
It's completely false as in lead pipes didn't have anything to do with the fall of the Roman Empire as originally mentioned in the top comment.
kmeisthax•6mo ago
The Roman Empire did not fall because of lead pipe. It fell because the empire's elites ran out of territory to conquer and turned against one another.

Also, the Roman Empire didn't fall, either. It split in two. The Western half continued splitting into a bunch of competing kingdoms while the Eastern half slowly shrank over about a thousand years. It eventually wound up being rolled into the Ottoman Empire, which lasted until WWI.

bigmattystyles•6mo ago
Don’t lead pipes or any pipes for water actually get a patina of calcium carbonate or something so while not great it’s not as bad as told. Only if the ph of the water changes because you change the water source, kinda like in flint?
bongodongobob•6mo ago
Yes. There's nothing wrong with lead pipes.
bigmattystyles•6mo ago
Not sure if sarcasm if I don't know enough beyond my own comment that I remembered from a PBS documentary.....
throawaywpg•6mo ago
Apparently it wasn't the pipes, which wouldn't have leached enough to make a difference. It was the fact that the Romans used lead acetate as a sweetener in their food and drinks!
boston_clone•6mo ago
Could you provide some evidence to support your assertion that highly enriched foods are degrading health?

Public health experts contend that enriched foods have improved baseline quality of life. Wheat breads with iron, folate, and B vitamins in the US is an easy example.

cpursley•6mo ago
Trace those public health experts funding sources...

Hint: it's the farm-bill dependent carb farmers who apparently need our money via farm subsidies and want poor people hooked as they get it from the other end in the form of SNAP.

boston_clone•6mo ago
No; this is a deliberately misleading non-sequitur with decades of evidence to refute.

https://pmc.ncbi.nlm.nih.gov/articles/PMC10609867

cpursley•6mo ago
The American waistline disagrees. The idea that highly processed sugar added white bread with all fiber and nutrients stripped with token vitamins added are added is a good thing is ludicrous. Why not just promote eating real food, including real bread?
boston_clone•6mo ago
It sounds like you're hypothesizing / gish galloping / strawmanning until you find something that "sticks".

Instead try researching things that support your claim, like the notion that sugary beverages are the main culprit to the obesity epidemic, even though most health experts don't have the evidence to isolate that as the core factor.

https://pmc.ncbi.nlm.nih.gov/articles/PMC9611578/

JumpCrisscross•6mo ago
> Could you provide some evidence to support your assertion that highly enriched foods are degrading health?

Getting nutrients from whole foods is generally superior, for absorption and balance and avoiding overdosing, than getting it from supplements, whether taken directly or via enrichment.

That said, getting a nutrient any way is better than running a deficiency. For most of agricultural human history, in most societies, most of the population was nutritionally sufficient [1]. That changed with enrichment. It’s healthier to eat whole over enriched food; it’s better to have enriched food versus a vitamin decency.

It’s ahistoric to claim we’re unhealthier today than we’ve been over most of human history. But we can do better. In that way, Roman pipes brought clean water to its populations in a way that made them healthier than people had been in cities to date. But it also gave them lead poisoning, which while better than cholera, is worse than no lead.

[1] https://pmc.ncbi.nlm.nih.gov/articles/PMC9460423/

boston_clone•6mo ago
> That changed with enrichment.

You’re close. According to the paper, that changed with agriculture some 480 generations ago; enrichment is merely the solution.

JumpCrisscross•6mo ago
> that changed with agriculture some 480 generations ago; enrichment is merely the solution

Whoops, typo—I meant nutritionally deficient.

Hunter-gatherers had a varied but volatile diet. Agriculture solved the volatility at the expense of variety. Most agricultural humans across history were nutritionally deficient.

Enrichment (a/k/a fortification) started to solve for the lack of variety, though it’s been historically stymied by our lack of understanding what e.g. vitamins are; modern farming, biology and logistics enable us to actually solve for the problems agriculture introduced to society for the first time.

slumberlust•6mo ago
If interested in Ultra Processed Foods, of which enriched foods usually are UPF, you can check out a good book called Ultra Processed People. It's not definitive, but it makes a compelling argument that while we don't know why exactly, processed foods containing the same nutrients as their whole brethren have deterious effects on our long term health.
boston_clone•6mo ago
I don’t think that’s a compelling argument; salt, for example, is also a common ingredient in “UPF”s (caveat emptor - there is no settled definition on that term).

The crux is that adding vital minerals to food is good. We can certainly distinguish between that and a Dorito.

tim333•6mo ago
The Victorians used lead pipes and then the British Empire declined. Coincidence?
djtango•6mo ago
I can't remember where (maybe here) that you shouldn't use mouthwash after working out because of the effects on your oral microbiome. That fact shocked me just like this article does because it was unintuitive that your oral microbiome could have such an impact on your physiology.

The effect may actually be a similar one because nitrates do sound familiar...

DuzAwe•6mo ago
Alcohol or just fluoride?

I have an aversion to the alcohol washes after reading years ago that the change to your mouth biome may lead to the issues that they are meant to stop.

ta988•6mo ago
fluoride with no kind of antibacterial is fine (careful with thymol etc). Check your toothpaste for anti bacterial as well. you want to remove food and plaque, not good bacteria.
justinator•6mo ago
But fluoride IS antibacterial.
christophilus•6mo ago
You shouldn’t use mouthwash at all ever. It’s a nuke to the microbes in your mouth. There was a long, rambling discussion with a functional dentist on the Primal Podcast[0] that goes into this.

> long, rambling discussion with a functional dentist on the Primal Podcast

I don’t know what a “functional dentist” is, but the term “functional medicine” is used to describe alternative medicine doctors. They traditional misinterpret studies and exaggerate their impacts, focusing on small studies in mice or theoretical in vitro studies and then extrapolating those to treatment decisions.

kaleinator•6mo ago
In my own personal experience (chronic pain), "Real Doctors" seem to want to shove pills down your throat because "they work", or give things like steroid shots which have negative long term effects. Whereas "Functional Doctors" are willing to try more traditional things because historically they have seemed to produce good results and are typically less intrusive (but may require more effort from the patient).

So I can see "Functional Dentist" being more like a dentist that is willing to try more ways to save teeth & gums by using more traditional methods (eg. Balancing the oral microbiome, suggesting softer foods more often), rather than a "Real Dentist" suggesting extractions or root canals without ever mentioning the hardness of foods or oral microbiome.

djtango•6mo ago
It's unpopular to voice anti-science sounding sentiments about medicine but it's worth noting that there is often a disconnect between known and practiced medicine.

Optimal outcomes at the aggregate don't always translate to optimal outcomes for the individual.

This can mean that strategies like effective triage and prioritization lets people fall through the cracks of conventional medical treatment. This is especially true for both public healthcare and separately chronic issues which are often too hard to treat vs acute medicine.

Then in private medicine it can be a bit of a crapshoot of practitioners who are incentivised to upsell or recommend preferred treatments.

I think this has soured people's opinions of conventional medicine.

My own personal anecdote to offer on the subject is a friend who suffered from severe eczema and over their life and was just put on progressively higher doses of steroids until that stopped working. The last advice from the doctor was "we give up - our next recommendation is chemotherapy to shock your body. Maybe you would like to consider alternative medicine first"

They went to try traditional Chinese medicine and for the first time in their life got control of their eczema.

Given alternative medicine is a dirty word here what I'd say is missing these days is the family doctor who has excellent holistic patient history and is willing to provide a mixture of therapy and lifestyle guidance eg exercise or nutrition intervention.

Some people might claim a GP should do this but the reality is that GPs often aren't allowed to provide this kind of care due to capacity constraints or top down strategic planning.

Ironically you see the gap being bridged from the other direction with therapists increasing their scope - eg someone close to me went to an osteopath for neck issues to get diagnosed (correctly!) that the root cause was sleep apnoea

red-iron-pine•6mo ago
what does "chinese medicine" mean? was he huffing ground up rhino horn?

most chinese medicine is hokum, utter BS, but that doesn't mean they can't use plants whose utility have not been fully explored by modern science.

and even if it does work, that doesn't mean it didn't utterly ravage his liver -- but hey, at least his skin looks a lil better

chemmail•6mo ago
If you look at the US healthcare system, it is 100% about fixing after the fact rather than prevention. Insurance would touch anything preventative.
Aurornis•6mo ago

Whereas "Functional Doctors" are willing to try more traditional things because historically they have seemed to produce good results and are typically less intrusive (but may require more effort from the patient).

This is the functional medicine fallacy: That “real doctors” are “shoving pills” that are secretly bad for the patient, while functional medicine doctors are also “shoving pills” but they’re a laundry list of supplements and traditional remedies.

In my experience, the functional medicine practitioners push far more pills and unnecessary tests than anyone else, but they’re given the benefit of the doubt because they’re operating under the alternative medicine fallacy that primary care doctors are the ones doing the bad things.

> (but may require more effort from the patient).

This is another concept used to justify the ineffective alternative medicine treatments; If they don’t work, it’s the patient’s fault for failing to do some effort. Another common explanation for when they don’t work is to “discover” yet another thing that needs to be treated. The additional demands of the patient are also designed to create buy-in which amplifies any placebo effect. The more rituals and supplements you can get a patient taking, the more they believe it’s going to work.

specialist•6mo ago
Same.

I went to Swedish Hospital's Pain Services Clinic. https://www.swedish.org/services/pain-services Transformative.

Funny thing: the techniques and skills they teach work, even if you don't think they will.

I think most (all?) new age stuff -- naturopathy, chiropractics, reiki, whatever -- is BS. But I can't argue with my lived experience of using tai chi, mindfulness, education, and other new skills to proactively manage my disease.

This is my first time hearing (reading) the phrase "functional doctor". WebMD defines them as specialists in digging deeper, seeing the whole picture. Perfect.

--

YMMV. Consult your doctor, etc. Most treatments don't help with treatment resistant conditions. Beware adverse effects. Yadda, yadda.

thenaturalist•6mo ago
Erythritol and Xylitol do have a strong correlation with severe coronary diseases and risk of strokes under certain preconditions according to newer studies though.

Also not really advisable for people with Irritable Bowel Syndrome.

Beijinger•6mo ago
This is true but how much will your body absorb via a mouthwash?

Erythritol is commonly found in sugar-free or keto-friendly products like beverages, desserts, and snacks. A single serving of an erythritol-sweetened product (e.g., a sugar-free soda, keto ice cream, or protein bar) often contains 10–30 g of erythritol.

Studies, such as the 2023 Nature Medicine study, used a 30 g dose in intervention experiments to simulate typical consumption (e.g., one sweetened beverage or dessert). This dose raised plasma erythritol to 5–7 mM within 30 minutes, a level linked to increased platelet reactivity and clotting risk.

canucker2016•6mo ago
What are your sources?

Peter Attia has a blog entry about the weak xylitol-cardiovascular disease research. For Xylitol, see https://peterattiamd.com/xylitol-and-cvd/

  The problem with interpreting these results as a condemnation of xylitol consumption is that diet isn’t the only source of circulating xylitol. This compound is also produced by our own bodies through a process known as the glucuronate pathway, one of the pathways by which we metabolize glucose. So how did the authors ensure they were investigating the relationship between dietary xylitol intake and MACE risk?

  They didn’t. ...
Attia also brings up something the study authours noted:

  The rapid rate of xylitol excretion observed in healthy volunteers with return to near baseline (fasting) levels within hours following ingestion of a significant dietary exposure suggests that the plasma levels observed in our observational (validation) cohort represent variations in endogenous production/levels and not food intake.

there are mouthwashes that don’t nuke everything in your mouth. Just FYI in case you’re unaware. They are not popular but they exist. The added benefit is it doesn’t burn either lol.

It’s extra beneficial if you live in a state / country that doesn’t add fluoride to drinking water.

nradov•6mo ago
That's interesting. I had always assumed that the effect was due to vasodilation but perhaps not.
giantg2•6mo ago
It is. The article is about how the beet juice affects the microbiome in a way that increases the conversion of nitrate to vasodialating nitric oxide.
healsdata•6mo ago
Isn't nitrates what makes processed meats so unhealthy? Does this mean the bacon that claims to be cured with celery juice is actually on to something?
xyzzy_plugh•6mo ago
No, you're thinking of nitrites. Celery juice is very high in nitrates, which then get converted to nitrites, which they don't have to put on the label. It's entirely marketing. Nothing has materially changed.
cobbal•6mo ago
Celery is just a "natural" source of nitrates/nitrates. This makes it legal somehow to lie and claim "no added nitrates" on the label.
Workaccount2•6mo ago
I can't believe the tiktok health cult hasn't caught on to this yet.

Seed oils are the devil but "uncured" meats? All good!

mrob•6mo ago
The main preservative for processed meats, and the one that reacts with other compounds to form carcinogens, is nitrites not nitrates. Nitrates are sometimes used too, especially for meats that are cured for a long time, because some bacteria will reduce them to nitrites, making them effectively work as a sustained release form of nitrite. See:

https://en.wikipedia.org/wiki/Curing_salt

jijijijij•6mo ago
But the article paints this bacterial conversion of nitrates as beneficial. It’s unclear whether the conversion into nitric oxide implies the conversion into nitrites. To me it seems likely the NO benefit may come with nitrosamine production, which may raise colon cancer risk.

I think nitrosamines aren’t exclusively formed in the gut, but are present in cured meat beforehand, though. As far as I know, vitamin C prevents the nitrite to nitrosamine reaction, so fresh nitrate rich vegetable juices may not be inherently harmful through secondary nitrosamine production from converted nitrites. Additionally, their amino acid content is probably low, so as long as they are not consumed with a meal, production may be limited.

hinkley•6mo ago
Celery root contains nitrites which has been the loophole people are using for cured bacon with “no nitrites” by which they usually say something like no artificial nitrites.
healsdata•6mo ago
Thank you, I appreciate the correction and additional information!
morninglight•6mo ago
Yes, this creates real confusion. Does this mean that you can eat a dozen hotdogs if you wash them down with a glass of beetroot juice?

If you are still not confused read this:

"Although prevalent in the diet, nitrates have been viewed negatively because they chemically form carcinogenic nitrosamines in acidic environments, e.g. stomach, purportedly leading to gastric cancer as well as neoplasia of the intestine, brain, pancreas, and contributing to Non-Hodgkin’s lymphoma. "

No. Beeting your meat is not the solution to that particular problem.

If you have trouble in bed, ask yourself if you use Listerine. It kills your mouth’s microbiome and lowers your Nitric Oxide production [0].

[0] https://pubmed.ncbi.nlm.nih.gov/31709856/

riffraff•6mo ago
I don't use Listerine but I didn't get this: trouble in bed of what kind? I couldn't get it from the linked article.

I never knew high blood pressure correlates with bad sleep or bad sex (if anything, meds for high blood pressure come with negative effects on that).

hotpotat•6mo ago
The physical performance kind. Conversely beet root, L-Citruline, and supplemental NO are commonly used for ED. That’s why medications like tadalafil and sildenafil work. NO relaxes your blood vessels and increases blood flow generally.
Workaccount2•6mo ago
Nitric oxide relaxes your blood cells, letting blood flow easier into parts that erect themselves with blood.

Try taking arginine for a week if you want to experience the effect first hand.

adastra22•6mo ago
> I never knew high blood pressure correlates with bad sleep or bad sex.

I don't know about bad sleep, but definitely bad sex. ED is an early indicator of hypertension.

rickydroll•6mo ago
From personal experience, yes, it does. My blood pressure comes down only when I sleep in a very quiet room with no light.
adastra22•6mo ago
I was mixing up correlation and causation, which is also some kind of irony my tired/jet lagged brain is too foggy to work out.

Correlation has no causation direction so you are absolutely right.

What I meant is that ED can be caused by hypertension, so if you get ED you should start checking your blood pressure. AFAIK chronic bad sleep doesn’t CAUSE high blood pressure in the same way. Not sleeping well will elevate your blood pressure, but not make it chronically worse. Put differently, if you have trouble sleeping at night, that doesn’t mean you have elevated risk of high blood pressure when rested.

But yeah, if you have high blood pressure (as I do), getting good sleep makes a huge difference in your numbers.

cstrahan•6mo ago
> if anything, meds for high blood pressure come with negative effects on that

It’s really a mixed bag.

Recall that Sildenafil (aka brand name Viagra) was originally developed to treat high blood pressure. Turns out that while it does lower blood pressure, it’s really good for improving erections.

giantg2•6mo ago
And get sun exposure since your body will synthesize it.
leke•6mo ago
Does sun exposure increase nitric oxide?
giantg2•6mo ago
Yes
storus•6mo ago
Humming increases NO as well. Maybe you should hum after taking Listerine for a while? I thought one of Listerine's main (unwritten) selling points was that it helps with sex (smell, prophylaxis for STIs).

Comfortable and uninterrupted sleeping, eating mostly plants, and getting your heart rate up and muscles moving for half an hour per day.

Anything else is going from 90% healthy to 99%.

dinfinity•6mo ago
I'd like to add: Stretching or some other kind of flexibility improving activities. Muscles moving for half an hour a day doesn't (necessarily) do anything for that (may even make it worse if you're doing heavy stuff).

The effects on quality of life of a bit of flexibility are huge. Back pain, knee pain, shoulder pain, "RSI", and so many other ails are often just pretty much permanently cramped muscles negatively affecting ligaments and nerves.

pstorm•6mo ago
Being flexible is important, but the latest research shows that heavy lifting improves flexibility about as much as a dedicated stretching program: https://pmc.ncbi.nlm.nih.gov/articles/PMC9935664/
rafaelmn•6mo ago
On the phone so can't see study details - what do day consider strength training ? I used to lift heavy (well by regular people standards) and for example my squat mobility was shit. Trying to improve that with significant load would have ripped my tendons I feel. Decreasing the load to the point where it wouldn't might as well be called stretching cause it wouldn't qualify as heavy lifting. Also most powerlifters I know have shit mobility.
adrianN•6mo ago
For the movements that you happen to make with the barbell.
scotty79•6mo ago
Yeah, I noticed that after a certain age if you want to retain ability to do the movement you need to do that movement. Doing 20 others won't help with that one.
baxtr•6mo ago
This + avoiding cigarettes, alcohol and any other drug as much as possible.
underlipton•6mo ago
Biphasic sleep was probably more common before artificial light, and you really need to be moving every 30-45 minutes. Even just a couple of minutes of walking or doing some chore counts.
Aurornis•6mo ago
> Biphasic sleep was probably more common before artificial light

The last time I looked into this theory it wasn’t nearly as robust as I was led to believe. It got circulated as fact for a few years but the people pushing it didn’t really have as much evidence for it as I assumed.

underlipton•6mo ago
That doesn't make it false. And you'd expect something so radical as extending the lit hours of human life to affect our sleep, as it does many, many other species.
alfiedotwtf•6mo ago
Does caffeine consumption out watching horror films (to greet your heart rate up higher than normal) count, or does it have to be strenuous cardio?
scotty79•6mo ago
Caffeine destroys sleep for many people. I wouldn't touch it.
mariusor•6mo ago
I think this is also one of the latest "marginal gains" advantages the cycling pro peloton is making use of. After races you can see them all chug a 150-200ml bottle of beetroot juice as a recovery drink while making the afferent faces. :D
cowmoo728•6mo ago
beetroot juice was a few years ago and it's for a different purpose - nitric oxide to relax smooth muscle in the airways. the red recovery drink at recent events is tart cherry juice, which is thought to aid in muscle recovery.
ulf-77723•6mo ago
Some time ago I read the book Complete Guide to Sports Nutrition by Anita Bean, which does also emphasize on not using antibacterial mouthwash since it removes the beneficial bacteria in the mouth which convert nitrate to nitrite.

I‘m drinking beetroot juice since 3 years now and asked myself if beetroot capsules might be an alternative.

fhars•6mo ago
How would capsules affect the mouth biome, though?
ulf-77723•6mo ago
Not sure, probably it doesn’t - in this regard the capsules might just be snake oil if they are not good in any other way
dinfinity•6mo ago
For people who don't like drinking beetroot juice, you can also regularly (French) kiss with people with healthy oral microbiomes [0][1]. Best to really get in there.

I recommend using a mouthwash based on xylitol which kills strains like streptococcus mutans but does not impair these nitrate reducers.
thenaturalist•6mo ago
Erythritol and Xylitol do have a strong correlation with severe coronary diseases and risk of strokes under certain preconditions according to newer studies though.

Also not really advisable for people with Irritable Bowel Syndrome.

stepanhruda•6mo ago
That’s for actually eating 10-15 grams.

Can’t speak for IBS, ymmv there, but similarly you are rinsing and spitting, basically just microdosing.

sleepyguy•6mo ago
Have you considered L-Citrulline as an alternative to Beet Root? There is a great YouTube video on DAOC with Dr Bryant. You might enjoy it.

You could also make Borscht with good quality beef for a balanced, healthy meal. It's the best.

For those who don't like beets, I eat beet regularly by dropping a few chunks in a fruit smoothie. Makes it nice and pink and the earthy flavor is much diluted.

I've baked a few beetroot cakes lately (substitute grated carrot for beetroot).

It's a little more bitter despite the outrageous sugar level, but wondering if the nitrates come through ok?

treetalker•6mo ago
Is there a material difference between drinking beetroot juice and just eating a mess of beets?
doytch•6mo ago
The dosage of this study was "2 × 70 ml ∙d−1, each containing ∼595 mg NO3−". That's probably gonna be tough to get daily by eating beets...
thallium205•6mo ago
One of the problems with beetroot though is that it is loaded with sugar.
jeffbee•6mo ago
So? Every living human needs a lot of calories every day.
hinkley•6mo ago
Thousands, even.
thenaturalist•6mo ago
If you do not differentiate between sugar and calories you clearly can learn a lot about the human digestion and microbiomes.

Complex (slow) carbs [does it feed your microbiome predominantly] != easy (fast) carbs [does it quickly go into your bloodstream and cells]

jeffbee•6mo ago
Calorie for calorie beetroot juice has the same sugar content as beets. I am certain you are not asserting that beets are not something that humans would normally digest.
thenaturalist•6mo ago
Well the difference between the veggie and the juice is that the former contains a whole lot more of fiber which is an especially beneficial nutrient for our gut microbiome.

Reading up on juices, I've only heard of experts not being fans of 'em.

hombre_fatal•6mo ago
Well, you don’t need to guzzle 600 calories of it.

I wonder if they could test this by comparing blood pressures of older folks in Australia with those in other countries since I hear they really like beetroot there :)

I started consuming Beet Chews recently. I'm not convinced of it though.

I think it's just one of those things where I see a YouTube video and go to Amazon to add a new supplement to my life. Then once the supply of the supplement is up I choose not to re-up on it. That's what I'm planning for the Beet Chews too.

I wonder really how much it really lowers BP and what quantity to consume?

The linked article doesn't specify how much was consumed? A single cup? A liter? Likewise I'm just consuming 2 Beet Chews per day per the suggested serving size. But who knows if that really is the "minimum effective dose". There is value to the placebo effect of course, I'm taking something in order to convince myself I'm healthier.

_the_inflator•6mo ago
Beetroot juice is legal “doping”.

Of course nothing illegal, only natural, a disadvantage if you don’t utilize it for you.

There are beetroot parties at almost any Triathlon event for the runners, apnea divers also get a huge natural and healthy boost.

I use it for long runs I don’t really feel the difference every time, but stats and data speak their own language.

Give it a try, timing is a bit tricky depending on your feast.

But caution: don’t overdo it due to oxalate as potential risk.

And mustn’t be the juice, the beetroot itself already does the job.

pinkmuffinere•6mo ago
Do we know the mechanism by which this works? Is it just anecdotal, or is this studied at a population/statistical level?
canucker2016•6mo ago
from https://www.outsideonline.com/health/training-performance/be...

  The key ingredient in beet juice, from an endurance perspective, is nitrate. Once you eat it, bacteria in your mouth convert nitrate to nitrite. Then the acidity in your stomach helps convert the nitrite to nitric oxide. Nitric oxide plays a whole bunch of roles in the body. That includes cueing your blood vessels to dilate, or widen, delivering more oxygen to the muscles, faster.

The article summarizes the results of several studies into beetroot juice for physical athletic performance.

  I sent the following summary to Andy Jones, the scientist most associated with beet juice research, to see whether he would agree:

  “It works. It probably works less well in elites, like most things, but there may still be an effect. Higher doses taken for at least a few days in a row probably increase your chances of a positive effect.”

  Jones thought that sounded reasonable. He pointed out that there’s a separate body of evidence emerging that beet juice also enhances muscle strength and power in some circumstances, an effect that Poon’s review confirms.
jbotz•6mo ago
I see everybody talking about the nitrate, but there is another substance in beets that might be relevant... betaine, also known as trimethylglycine HCL. I take about 800mg of this pure in my orange juice in the mornings and it gives me a very noticeable boost. But it is possible that this effect is specific to me and maybe other people who are "under-methylators" (which I think is a somewhat pseudo-scientific concept, but it led me to try betaine and I got results).

Betaine was first isolated from beets, hence the name, and as the other name, trimethylglycine, hints it has 3 easily donated methyl groups, so if you do need those for some reason it may be useful to you. It's also pretty cheap and unlikely to be harmful.

Edit: I found this... https://www.strongerbyscience.com/betaine/

ponector•6mo ago
Should be a raw juice or polish beetroot soup (barszcz) does the job?
ck2•6mo ago
Well no if it changed it then you wouldn't need to keep drinking it for the same effect

It's the nitrates which have a short half-life

And the thing is high quality Beet juice is very expensive because it has to be grown in good soil with lots of nitrates, most of the stuff coming out of China is poor quality with just the name and people don't know any better
