A gut health scientist easily eats 50 grams of fiber a day. Here's her breakfast, lunch, and dinner.

Dr. Megan Rossi, a gut health scientist at King's College London, recommends consuming 50 to 60 grams of fiber daily because it feeds beneficial microbes in the gut microbiome. Fiber is derived from plant foods like whole grains, fruits, and seeds, influencing overall health by supporting the gut lining and mood. Rossi demonstrates her high-fiber intake with meals such as fermented overnight oats for breakfast.
