7 Common Food Myths Most People Still Believe
From diet fads to old wives’ tales, food myths are everywhere—and many of them are still widely believed despite scientific evidence. Experts weigh in on the misconceptions that can affect how you eat, cook, and think about your health. Here are 7 common food myths debunked.
Carbs Make You Gain Weight
The Truth: Carbohydrates alone don’t cause weight gain—overeating calories in any form does. Whole grains, fruits, and vegetables are essential for energy and nutrition.
Expert Insight: Registered dietitian Keri Gans says cutting carbs completely is rarely necessary for most people.
Eggs Are Bad for Your Heart
The Truth: Eggs contain cholesterol, but research shows moderate consumption doesn’t significantly raise heart disease risk for most healthy adults.
Expert Insight: Nutritionist Toby Amidor calls eggs “a nutrient-packed, versatile protein source.”
Microwaving Kills Nutrients
The Truth: Microwaving can actually preserve nutrients better than boiling, since cooking times are shorter and less water is used.
Expert Insight: Food scientist Dr. Jillian McKee confirms that microwaving is safe and effective for maintaining vitamins.
Fat Makes You Fat
The Truth: Healthy fats from nuts, avocados, and olive oil are essential for your body and don’t inherently cause weight gain.
Expert Insight: Registered dietitian Lisa Moskovitz emphasizes that fat is a key nutrient for hormone balance and satiety.
You Must Drink 8 Glasses of Water a Day
The Truth: Hydration needs vary depending on body size, activity level, and climate—there’s no universal magic number.
Expert Insight: Nutritionist Cynthia Sass recommends listening to thirst and checking urine color for hydration cues.
Eating Late at Night Makes You Gain Weight
The Truth: Weight gain is about total calories, not the time you eat them. Eating mindfully at night isn’t inherently harmful.
Expert Insight: Dietitian Rania Batayneh notes that timing is less important than the quality and quantity of food.
Frozen Vegetables Are Less Nutritious Than Fresh
The Truth: Frozen veggies are often picked and flash-frozen at peak ripeness, which can lock in nutrients better than fresh produce that travels long distances.
Expert Insight: Chef and nutritionist Ellie Krieger says frozen vegetables are a convenient, healthy option year-round.
