Key takeaways

  • Rice, corn, buckwheat, quinoa, legumes and vegetables are naturally gluten-free and should be the base of your diet.
  • Whole rice and corn versions help cover the fiber intake often lacking in refined gluten-free products.
  • A simple, repeatable meal plan reduces reliance on industrial substitutes.
  • Not all industrial gluten-free products are equal: they often have a higher glycemic index and less fiber.

Not just industrial substitutes

Rice, corn, buckwheat, quinoa, legumes and vegetables are naturally gluten-free and should form the basis of the diet, more so than packaged substitute products.

Fiber and gluten-free whole grains

Choosing whole versions of rice and corn, together with legumes and seeds, helps maintain adequate fiber intake, often lacking in diets based on refined gluten-free products.

A sample day of eating

Breakfast with buckwheat flakes and fruit, lunch with whole grains and lean protein, a light dinner with vegetables and legumes: a simple routine you can repeat every day.
