The donut vs donut hole debate is a trap, though, that even the most brilliant breakfast-savvy mathematician fall into.

Truth is, the original flat flakes had infinitely more glaze than either the donut hole or the donut, mathematically speaking.

But because Kelloggs compared the donut hole to the donut, people are easily tricked into settling for the most optimal of these two shapes, while completely ignoring that either shape is a massive step backward for any cereal lover out there.

This is blatant case of enshittification, Kellogg's. It's not Grrrrrrrrrrrrrrreat.

Maybe. I haven’t done the math.

> INGREDIENTS: Whole Grain Yellow Corn Flour, Sugar, Degerminated Yellow Corn Flour, Modified Food Starch, Contains 2% or Less of Hydrogenated Vegetable Oil (Coconut, Soybean and/or Cottonseed), Natural and Artificial Flavor, Brown Sugar Syrup, Salt, Enriched Flour (Wheat Flour, Niacin, Reduced Iron, Vitamin B₁ [Thiamin Mononitrate], Vitamin B2 [Riboflavin], Folic Acid), Red 40, Yellow 5, Blue 1, Yellow 6, BHT for Freshness, Vitamins and Minerals: Iron, Niacinamide, Zinc Oxide, Vitamin B1 (Thiamin Hydrochloride), Calcium Pantothenate, Vitamin B6 (Pyridoxine Hydrochloride), Folic Acid.

Entirely relatedly, butylated hydroxytoluene (BHT) exposure above 0-0.3 mg/kg bw/day is potentially deleterious based on effects in the reproduction segments and (precancerous) hepatic enzyme induction seen in two separate 2-generation studies in rats.[2] Quoting a rather dry academic paper:

> The Panel noted that exposure of adults to BHT from its use as food additive is unlikely to exceed the newly derived ADI [acceptable daily intake] of 0.25 mg/kg bw/day at the mean and for the high consumers (95th percentile). Exposure of children to BHT from its use as food additive is also unlikely to exceed this ADI at the mean, but is exceeded for some European countries (Finland, The Netherlands) at the 95th percentile. If exposure to BHT from its use as food contact material is also taken into account the new ADI would be exceeded by children at the mean and at the 95th percentile [everywhere].

Given that iron is listed after BHT (and therefore presumably is present at a lower concentration), I'll stick to toast & oats for breakfast, thanks...
