Grain Brain is about improving brain health through eating more "good fats" and less grains, sugars and processed carbs. Dr. Perlmutter says this diet helped many of his patients lower their weight, blood sugar, inflammation and cholesterol levels—thereby decreasing their risk for dementia, diabetes and other chronic diseases.
How to Not Die reveals the connection between what we eat and chronic diseases. Based on hundreds of references to scientific evidence, Dr. Michael Greger shows how to prevent (and even reverse) the top causes of death like heart disease, most cancers, diabetes, obesity, strokes and Alzheimer's.
The Plant Paradox says lectins are bad. Lectins are proteins hidden in some plants like grains, beans and tomatoes. Dr. Gundry claims they cause many health problems rampant today (like obesity, diabetes and autoimmune diseases) and if you avoid lectin-producing plants, you will lose weight, live longer and feel better.
