Aluminum37 ppmof 0.2 ppm

Over the limit — 185×FDA bottled-water Standard of Quality (secondary/aesthetic), 21 CFR 165.110(b) — 0.2 mg/L. NOTE: this is a bottled-water level; it is not an FDA limit for aluminum in solid foods, where no comparable federal limit exists.

Glyphosate12.8 ppbof 160 ppb

8% of the limitEWG children's health benchmark 160 ppb (0.01 mg/day in a 60 g serving). EPA tolerance for glyphosate on oats is far higher at 30 ppm (30,000 ppb), 40 CFR 180.364.

Aminomethylphosphonic Acid2.21 ppbof 160 ppb

1% of the limitNo regulator publishes a food concentration limit for AMPA alone. EFSA (2023 glyphosate conclusion) and JMPR state glyphosate's toxicological reference values apply to AMPA (shared group ADI), so Tallow applies glyphosate's benchmark: EWG children's health benchmark 160 ppb (0.01 mg/day in a 60 g serving). Water-only references: EU drinking water 0.1 ug/L per pesticide/metabolite; Minnesota MDH guidance 1,000 ppb.

Common questions

Is Kellogg's Corn Flakes healthy?

Kellogg's Corn Flakes scores 0/100 on Tallow — our avoid band. That number comes from what is on the label: the ingredients, how processed it is, and what it is packaged in, plus lab results from its product family, Corn Flakes (US). Per serving it carries 1g fiber, 2g protein and 3g sugar. It is not a verdict on your diet — Tallow does not weigh calories, portion size or how often you eat it, so a high score means the ingredients are clean, not that the food is unlimited.

What is in Kellogg's Corn Flakes?

Kellogg's Corn Flakes lists 20 ingredients, starting with Milled Corn, Sugar, Malt Flavor, Salt and Bht. Ingredients are listed in descending order by weight, so the first few make up most of what you are eating.

How many calories are in Kellogg's Corn Flakes?

100 kcal per serving, or 357 kcal per 100g. Calories are only part of the picture — Tallow scores Kellogg's Corn Flakes on what the ingredients are, not how many calories they carry.
