Medical researchers examined the effects of consuming peanuts
Cardiovascular diseases are diseases of the heart and blood system. Such diseases lead to a large number of deaths in Germany. Researchers have now found that consuming peanuts can help prevent heart attacks and strokes.
In their investigation, researchers at Pennsylvania State University in the USA found that eating peanuts reduced the risk of cardiovascular diseases. The doctors published the results of their study in the journal "Journal of Nutrition".
Subjects consume peanut shakes while eating
For their study, the experts examined 15 healthy but overweight or obese men. During the study, the participants took a control meal with about 85 grams (average serving size) of unsalted peanuts in the form of a shake. A control group received a shake with a similar nutritional amount and quality. However, these shakes did not contain peanuts, the American experts explain.
Peanuts reduce the typical increase in triglycerides after a meal
The measurements say that the lipid, lipoprotein and insulin levels were measured in all subjects. These measurements were taken 60, 120 and 240 minutes after consumption. The researchers found that consuming peanuts reduced the triglyceride level by 32 percent compared to the control group without peanut shakes. Eating peanuts during a meal reduced the typical increase in triglycerides after a meal, the authors explain.
Peanuts keep arteries more elastic
Eating peanuts appears to support the cells that keep the arteries healthy. As a result, the arteries remain more elastic, the researchers explain. As a rule, eating meals causes the arteries to stiffen a little after eating.
Consuming peanuts prevents stiffening of the arteries after eating
Results found during the study show that consuming a few peanuts together with meals can prevent artery stiffening, says author Dr. Penny Kris-Etherton from Pennsylvania State University in the United States.
Stiffening of the arteries increases the risk of serious cardiovascular problems
Over time, the arterial stiffening reaction can limit blood flow throughout the body. This effect then causes the heart to work harder, the experts explain. As a result, the risk of serious cardiovascular problems increases over time.
Peanuts prevent reduction in artery dilation
As the heart has to work harder and harder over a long period of time, this could eventually lead to heart failure, says the author Dr. Kris-Etherton. After a meal, the triglycerides increase, which usually reduces the dilation of the arteries. But eating peanuts can prevent such an effect, the expert adds. (as)
