Title:
The effect of pecans on selected cardiovascular disease risk factors: a pilot study.

Summary: In a previous six-year population study of diet and heart disease we found that frequent consumption of nuts reduces risk of myocardial infarction (heart attack) and death from coronary heart disease. To identify the mechanism(s) of the possible protective effect of pecan consumption on heart disease, we carried out a well-controlled human feeding trial with pecans. After a 2-week adaptation period, 24 participants were fed, in random order, a diet rich in pecans (3 one-ounce servings/day) and a diet free of nuts as reference, each for 4-weeks. At the end of each period, blood lipids (total, LDL an HDL cholesterol), serum vitamin E and fatty acids were measured. Satiety and daily caloric intakes was also assessed.
