Corn Flakes

A low-fat, fortified breakfast staple that is highly refined and low in fiber, with added sugar and a high glycemic impact, so it is fine occasionally but not a nutritional powerhouse.

High glycemic index: it can cause a quick blood sugar spike, especially if eaten without protein or fiber.
Low in fiber (around 3g per 100g), so it is less filling than whole grain cereals.

Ingredients (6)

Maize (Milled Corn)

aka Corn grits

Maize is a natural whole food, but milled and heavily processed into flakes it loses most of its fiber and has a high glycemic index (around 80+), so it raises blood sugar quickly.

Daily Intake — Provides most of the ~84g carbohydrate per 100g; a 30g serving gives about 25g carbs (roughly 9% of daily value)
MODERATE

Sugar

aka Table sugar (sucrose)

The amount is modest compared with frosted cereals, but it is still added sugar in a product that is already quickly digested. Check regional labels, as sugar content varies.

Daily Intake — About 2-3g per 30g serving (around 3% of the daily free sugar limit); higher in some regional versions
MODERATE

Malt Flavouring (Barley Malt Extract)

aka Malt extract

A natural flavoring that adds sweetness and toasty flavor. It is derived from barley, so it contains gluten and makes the product unsuitable for coeliacs.

Daily Intake — Small quantity, but it adds extra sugars and contains gluten
MODERATE

Salt

aka Sodium chloride

Cereals are an often overlooked source of sodium. The level is moderate, but it adds up alongside other foods in the day.

Daily Intake — About 0.3-0.5g salt per 30g serving (roughly 5-8% of the daily limit)
MODERATE

Iron

aka Added mineral (fortification)

Fortification helps prevent iron deficiency, especially in children and women. Amounts are within safe limits for a normal diet.

Daily Intake — Typically provides about 25-30% of the daily reference value per serving
SAFE

Vitamins (Niacin, B6, Riboflavin, Thiamin, Folic Acid, B12, D)

aka B vitamins and vitamin D

Added vitamins boost the nutritional value of a refined grain product. Folic acid is particularly valuable for women of childbearing age.

Daily Intake — Each typically supplies around 15-50% of the daily reference value per serving

Fun Fact

Corn Flakes were created by accident in 1894 when Dr. John Harvey Kellogg and his brother Will Keith Kellogg left cooked wheat dough sitting out; it went stale and, when rolled, produced flakes. The brothers later switched to corn, and W.K. Kellogg went on to found the Kellogg Company.

Made by Kellogg Company (now split, with the cereal business operating as WK Kellogg Co in North America and Kellanova for snacks)
