10 Nutrition Myths Americans Still Believe (That Science Has Debunked!)

Nutrition is a topic that affects everyone, yet misinformation spreads rapidly. Many Americans still follow outdated dietary advice that science has already debunked. These misconceptions can lead to poor eating habits, unnecessary restrictions, and even health risks. Let’s separate fact from fiction by addressing some of the most common nutrition myths in the U.S.

1. Myth: Carbs Are Bad for You

Truth: Carbs Are Essential for Energy

• Carbohydrates are the body’s primary energy source.

• The key is choosing complex, fiber-rich carbohydrates.
