It seems that pistachios may be beneficial in
lowering cholesterol. A study called "Pistachio Nut Consumption and Serum Lipid Levels" published in the Journal of the American College of Nutrition in April, shows that a four week pistachio diet can reduce cholesterol, and without any weight gain. This backs up a 2005 study published in the Journal of Agriculture and Food Chemistry which found that pistachios are the richest source of phytosterols in snack foods. Phytosterols are believed to reduce blood cholesterol.
The new study says that if you have high cholesterol, then a four week diet where 15 percent of your
calories came from pistachios can improve your blood serum lipid levels, and may reduce your rick of coronary disease. The diet didn't raise blood pressure or weight levels and was found to be quite healthy. So if you need to worry about your cholesterol levels and are looking for a snack, reach for those nuts and nibble on a few, and stay healthy.
