This might sound nuts: Spanish scientists say there is a connection between the humble peanut and healthy blood flow.
In the world of nuts, peanuts are a rock star. They are the most-consumed nut on Earth. They’re considered a healthy snack rich in nutrients. And let’s not forget: They are delicious.
Now researchers have given us another reason to love the little guys. In their study, a group of healthy young people, ages 18 to 33, added peanut products to their daily diet for six months.
Perhaps it’s appropriate that Spanish researchers are involved in this work. The peanut is thought to have emerged from South America. Archeologists discovered peanut-shaped jars made by the Incas in Peru.
In time, Spanish explorers brought peanuts to Europe and to the lands of the New World.
The study found that those who ate more peanuts had significantly higher levels of lipid molecules that are markers of good vascular health. That is in comparison to a control group on a peanut-less diet.
The markers are indicative of lower risk for blood clots and healthy dilating blood vessels. Good blood flow through dilated vessels supports the healthy delivery of oxygen to the entire body.
Researchers note one reason the peanut might be a nutritional super nut is that they contain polyphenols, a natural compound found in fruits, vegetables and cereals.
Previous studies have shown that peanuts also are protective against cardiovascular disease and diabetes.
Investigators acknowledge more work is needed to analyze exactly how the peanut does what it does.
So, don’t switch to an all-peanut diet just yet.
