When it comes to nutrition, there’s no shortage of advice. Unfortunately, not all of it is true. Some myths have been repeated for so long that people assume they must be fact — but science says otherwise. Let’s bust some of the most common nutrition myths still fooling millions today.
1. Carbs Make You Fat
Carbohydrates often get blamed for weight gain, but the real culprit is excess calories from any source. Whole-grain carbs like oats, quinoa, and brown rice actually provide fiber and sustained energy. It’s the highly processed carbs (white bread, pastries, sugary cereals) that are the problem.

2. All Fats Are Bad
For decades, fat was demonized. The truth? Healthy fats — like those from avocados, nuts, olive oil, and fatty fish — are essential for brain function and hormone balance. It’s trans fats and excessive fried foods you should avoid.
3. Eating at Night Causes Weight Gain
Your body doesn’t care what time it is — it cares about how many calories you’ve eaten overall. Late-night snacking only leads to weight gain if it pushes you into a calorie surplus.
4. You Need to Detox with Juices
Juice cleanses are popular, but your body already has a powerful detox system: your liver and kidneys. Instead of pricey juices, support your body with whole foods, water, and plenty of fiber.
5. High-Protein Diets Damage Kidneys
For healthy individuals, eating more protein doesn’t damage the kidneys. In fact, higher protein intake can support muscle repair, weight management, and satiety. Only people with pre-existing kidney disease need to be cautious.
6. Fresh Produce Is Always Better than Frozen
Frozen fruits and vegetables are picked at peak ripeness and flash-frozen, locking in nutrients. In many cases, they’re just as nutritious — if not more so — than “fresh” produce that’s been sitting on a truck for a week.
7. Supplements Can Replace Food
Supplements should supplement, not replace, a healthy diet. A pill or powder can’t provide the same synergy of nutrients, fiber, and antioxidants you get from whole foods.
8. You Have to Cut Out Coffee for Better Health
Coffee actually contains antioxidants and has been linked to reduced risks of certain diseases. The key is moderation (2–3 cups a day) and avoiding loading it with sugar and heavy cream.

9. Skipping Meals Boosts Weight Loss
Skipping meals can backfire by slowing your metabolism and leading to overeating later. A balanced approach like intermittent fasting may work for some, but starving yourself usually backfires.
10. Gluten-Free Diets Are Healthier for Everyone
Unless you have celiac disease or gluten sensitivity, there’s no proven benefit to cutting out gluten. In fact, many gluten-free products are highly processed and less nutritious than their whole-grain counterparts.
The Bottom Line
Nutrition myths spread fast — but the science behind healthy eating is much simpler: eat more whole foods, limit processed junk, stay hydrated, and move your body.
