The relationship between diet and heart health has long been an important topic in scientific research.
Many studies show that what we eat every day can influence the risk of cardiovascular disease.
A varied diet typically consists of fruits, vegetables, meat, fish, and grain products, but nuts can also play a role in nutrition.
They contain fiber, protein, vitamins, and minerals.

According to nutritional data, nuts also contain a significant amount of fat. However, a large portion of this fat is polyunsaturated, which is often associated with a healthier fat profile.
Nutrition experts also point out that nuts are high in calories and should therefore be eaten in moderate amounts.
Body signals
Researchers are also examining how certain foods affect cholesterol levels in the body.
A meta-analysis published in the American Journal of Clinical Nutrition found an association between the consumption of certain nuts and lower levels of LDL cholesterol.

Researchers are also studying how diet may influence the body’s nervous system.
One area of focus is heart rate variability, which measures how much the time between heartbeats varies.
Higher variability is often associated with a better ability of the body to cope with stress.
At the same time, some studies have shown lower levels of inflammatory markers in the blood of people who regularly consume certain nuts.

The amount of walnuts
According to an article in elEconomista, cardiologist Aurelio Rojas discussed the research in a video on social media. In the video, he highlights one type of nut in particular.
That nut is walnuts. According to the studies mentioned in the article, a daily intake of about 30 grams, equivalent to approximately six to eight walnuts, may be associated with a lower risk of heart attack.
