You know exactly what we’re talking about. Fruity Pebbles, Lucky Charms, Cap’n Crunch and Cocoa Puffs — these popular breakfast options from your childhood packed enough sugar to get you pumped for school.

One cup of Honey Smacks cereal contains even more sugar than the average glazed doughnut, with 18 grams per serving (this figure increases when you add milk).

Starting your day with a sugary breakfast cereal can increase your blood sugar and insulin levels, making your body crave another high-carb meal once it wears off, according to Healthline.
