American researchers found that eating a small serving of walnuts daily reduced LDL cholesterol by an average of 4.3 mg / dl after two years. This is better known as “bad cholesterol”. The total cholesterol also decreased by about 8.5 mg / dl.
A total of 708 people between the ages of 63 and 79 took part in the study between 2012 and 2016. The study authors divided these into two groups: while half of all participants added nuts to their daily diet, the other group refrained from eating walnuts. Two years later, a doctor measured the cholesterol levels of all of the participants. The result: LDL cholesterol fell by around 7.9 percent in men and by around 2.6 percent in women.
“Eating a handful of walnuts every day is an easy way to promote heart health. Many people worry about unwanted weight gain when adding nuts in their diet. In our study, the participants did not gain weight because of the healthy fats, ”says Studio Co-Author Emilio Ros.
Nuts in general – and walnuts in particular – reduce the rate of heart disease and stroke. This can be explained, among other things, by the high content of high-quality omega-3 fatty acids.
