The speakers, shared a wealth of data on the influence of different types of diets on weight, blood pressure, lipids, serum inflammatory markers, hemoglobin A1c levels, and diseased coronary arteries. More than one pointed out that we too often overestimate the benefits of drugs and medical procedures and discount the effectiveness of diet and lifestyle changes. Some highlights:

He suggests that their diets include the American Heart Association’s recommendations for omega-3 fatty acid intake beginning in childhood (breast milk, flax seeds, walnuts, or child-friendly omega 3 supplements can be used in lieu of fish-derived omega 3s when mercury is a concern).
