Why Whole Foods Are a Better Choice Than Processed Ones 

Whole foods are ingredients you recognize—like apples, oats, chicken, and brown rice. Processed foods often include a long list of ingredients you’ve never heard of.

Why Whole Foods Are Better 

When you eat whole foods, you know what you’re putting into your body. You are getting:

  • Nutrients your body recognizes
  • No artificial chemicals or preservatives
  • Less sugar, less salt, fewer calories
  • More fiber, vitamins, and minerals

When you eat processed foods, you take in dozens of additives. Many of them have been linked to poor health outcomes—cancer, obesity, heart disease, and chronic inflammation.

Ask yourself:

  • Do you know what’s in your food?
  • Are you eating to nourish or just to satisfy?

Eat foods with ingredients you can pronounce. Cook more at home. Shop the outer aisles of the grocery store. Choose real over convenient.

Your body knows the difference.
