Eggs are bad for you? Fat makes you fat? It's time to bust the biggest nutrition myths.
From fad diets to food fears, nutrition misinformation is everywhere. This quiz draws from a pool of 50 questions testing your ability to distinguish real science from popular myths about eggs, fat, carbs, detox diets, superfoods, and more — rated medium difficulty for anyone who wants to eat smarter.
Each round presents 10 multiple-choice questions randomly selected from the full bank. Pick your answer, get an instant explanation backed by scientific consensus, and see your final score. Questions are randomized each attempt, so replay as many times as you like.
Questions cover the truth about eggs and cholesterol, whether fat really makes you fat, the science behind breakfast skipping, detox diet claims, organic versus conventional produce, the carbs debate, how much water you actually need, MSG safety, sugar and hyperactivity, gluten-free diets for non-celiacs, superfood marketing, late-night eating, multivitamin necessity, raw versus cooked vegetables, and protein supplement myths.
No strong scientific evidence supports this claim. It was popularized by cereal companies in the early 20th century. Intermittent fasting research shows that skipping breakfast is not harmful for most healthy adults, and meal timing matters less than overall diet quality.
For most people, no. Current research shows dietary cholesterol has minimal impact on blood cholesterol for the majority of people. Eggs are nutrient-dense, providing high-quality protein, vitamins, and choline. The 2020-2025 Dietary Guidelines for Americans removed the previous 300 mg daily cholesterol limit.
Your liver and kidneys already detoxify your body continuously. No scientific evidence supports commercial detox diets or juice cleanses as more effective than normal organ function. Most weight lost during detox diets is water weight that returns quickly.
