Published medical research provides the organising framework for Michael Greger's popular health and nutrition books advocating a predominantly whole-food plant-based diet. How Not to Die structures its chapters around major causes of illness and then discusses foods and dietary patterns associated with lower risk, ending with a practical checklist known as the Daily Dozen. How Not to Diet turns to weight management, appetite and the energy density of food, while How Not to Age applies the same evidence-review format to ageing and chronic disease. Greger's books are dense with study summaries but written for general readers, combining citations with shopping, cooking and meal-planning suggestions. They fit nutrition, plant-based eating and preventive-health non-fiction. Readers should treat them as popular interpretations of research rather than personalised medical advice, particularly where evidence or individual health needs are contested. Read more Less
