The Health Benefits of the Peanut

My game plan is to research, condense my findings, and translate it into everyday language for busy people.


Peanuts and Heart Disease

Eating a diet that includes a lot of peanuts is not just good for your overall health but especially good for preventing heart disease. Heart disease is the main killer of people in the United States and is also a major cause of disability. The narrowing or blocking of the arteries or the blood vessels supplying blood to the heart is the most common cause of heart disease. One of the ways to combat heart disease is through diet. The theory is that antioxidants increase the level of H.D.L.'s (the good cholesterol) and prevent cholesterol build up. Red wine has been known to decrease heart disease in people. The reason for that is because it has an antioxidant compound called “Reservatrol.” Reservatrol is found in grapes, blueberries, red wine, and peanuts. Scientists think that Reservatrol does have anti-cancer, anti-inflammatory, and anti-viral benefits.

Peanuts and Cholesterol

The peanut which grows in the ground is often not considered as good for your health as tree growing nuts like the walnut, pecan, or almond. It also is not nearly as expensive. However, the peanut was proved to be just as healthy as the tree growing nuts in a study that was published in JAMA Internal Medicine. A team of researchers figured out that people who ate peanuts on a regular basis were less likely to die of anything, especially heart disease, than people who rarely consumed any kind of nuts. They are more closely related to soybeans than tree nuts. Of the people who regularly ate peanuts, they were 21% less likely to die from anything than people who did not eat nuts over the time frame of five years. The mortality rate of people who were Chinese was 17 % lower among those who consumed nuts. The fats found in peanuts are heart healthy because they are non unsaturated and polyunsaturated. Both of these types of fats lower L.D.L.'s, cholesterol, and triglycerides. They also keep the H.D.L. or good cholesterol high. They also have extremely little saturated fat and no trans fat. Peanuts are a good source of protein and have been shown to lower blood pressure thereby lowering the risk of heart disease.


Peanuts and Fat

L.D.L.'s play a role in developing plaque that builds up the blood vessels. Eating peanuts also lowers your risk of blood clots which can cause a heart attack. They also improve the lining of your arteries. Peanuts are rich in monounsaturated fats which are emphasized in the heart healthy Mediterranean diet. In one study a diet high in monounsaturated fats reduced the risk of heart disease by 21% compared to the average diet in America. Peanuts are also a good source of Vitamin E, niacin, folate, manganese, and protein. Also, peanuts have 25% as much Reservatrol as red wine.

Health Benefits of the Peanut

Peanuts Prevent Alzheimer's Disease

Two nutrients, Niacin and Vitamin E have proven to protect people against Alzheimer's disease and other forms of cognitive decline related to getting older. Both of these vitamins are found in large amounts in peanuts. In one study it was shown that in 4,000 people over the age of 65 that the Niacin they got from food slowed the rate of cognitive decline. In people who were in the top fifth of intake of Vitamin E, the occurrence of Alzheimer's disease was reduced by 70 %. Also, Reservatrol which is in peanuts has also proven to be a contributing component in preventing Alzheimer's along with other nerve degeneration diseases. While it is thought there is not yet any 100% preventive treatment of Alzheimer's, the Reservatrol can play a significant role in at least slowing down the progression.
