Avocados are on the way to becoming the latest super food. Eating this luscious and satisfying fruit daily may be the key to lowering “bad” cholesterol, particularly the worst kind of low-density lipoproteins (LDL), according to a new study.
Avocados are a good source of B vitamins, vitamins C, E and K, magnesium and potassium. They also provide the antioxidants lutein and beta-carotene and are rich in omega-3 fatty acids. Most of the calories in avocados come from fat, but that’s no reason to avoid them because the fat they contain is healthy fat.
There are several types of LDL particles that circulate in the blood. The particles vary in size and density. Small, dense LDL particles are the most harmful, especially if they are oxidized. Oxidation in the body can be compared to what happens to an apple when you cut it and leave it sitting on the kitchen counter. The cut surface turns brown, or becomes damaged, as a result of the chemical process known as oxidation.
People who ate an avocado every day had lower levels of LDL cholesterol than they had before the study. They also had higher levels of lutein, an important antioxidant.
Not only did participants who ate an avocado every day have lower levels of LDL cholesterol than they had before the study or after eating the low- or moderate-fat diets for five weeks, they also had higher levels of lutein, an important antioxidant that may be the compound that prevents LDL, the bad cholesterol, from becoming oxidized in your body.
The dangerous, oxidized form of LDL was reduced in those on the avocado diet. Penny Kris-Etherton of Penn State explained in a statement: “A lot of research points to oxidation being the basis for conditions like cancer and heart disease. We know that when LDL particles become oxidized, that starts a chain reaction that can promote atherosclerosis, which is the build-up of plaque in the artery wall. Oxidation is not good, so if you can help protect the body through the foods that you eat, that could be very beneficial.”
Puree avocados and make a spread for your toast or a salad dressing. Make avocado soup. Stir up a creamy sauce to top chicken enchiladas. Add them to a smoothie.
