What you should know:
A randomized, crossover, controlled feeding trial on 45 healthy overweight and obese men and women, conducted at the Pennsylvania State University and funded by the Hass Avocado Board (HAB) was published in the Journal of the American Heart Association.
- The study evaluated whether incorporating one fresh avocado into the diet daily for five weeks could reduce bad cholesterol levels more than a diet that incorporated monounsaturated fat from vegetable oils high in oleic acid as a substitute for one fresh avocado. The diets were matched for calories and macronutrients, but not for fiber, phytosterols, or other bioactives.
- The study found that overweight/obese men and women who followed a moderate fat diet that included one fresh avocado significantly improved the ratio of total cholesterol to HDL, or “good” cholesterol (TC-HDL/-C) and the ratio of LDL, or “bad” cholesterol, to HDL-cholesterol (LDL-C/HDL-C).
- Additionally the avocado diet achieved the greatest reduction in LDL-cholesterol compared to a low-fat diet and moderate-fat diet without avocado.
