According to figures from the Spanish Society of Cardiologycardiovascular diseases They are the first cause of death in our country. Every eight minutes someone dies. spanish citizen therefore, according to data from the Spanish Society of Cardiology.

People who eat diets high in fat and cholesterol are more likely to develop conditions which can end up causing heart disease. Many are the factors that influence on heart health, and an important one is nutrition. So to help reduce the riskwe should opt for diets low in fat, sugar and salt, with lean meats. Avoiding processed foods can also help.

A handful of walnuts daily can become a great ally for our health. Walnuts have already been proven to have scientifically proven benefits for heart health after a study was conducted to look at their impact on the gut microbiome.

Effect of adding walnuts to your diet

the group of researchers analyzed and complemented the study designing a sample with three groups of people. in total, 42 people participated. The first group ate whole nuts and was dubbed the “nut diet group”. It consisted of patients who ate between 57 and 99 grams of nuts a day, about a cup of nuts. The second group consumed the same amounts alpha-linolenic omega-3 fatty acid found in walnuts without eating nuts. This was the “control diet”. The third group was assigned to consume oleic acid, also without eating nuts.


After 6 weeks on the diet, the researchers stool samples collected from participants and performed a genetic analysis of the intestinal microbiota of each group. With this, they were able to determine whether there was higher or lower levels of certain bacteria.

The results showed that people who ate the walnut diet had higher levels of the amino acid L-homoarginine in your intestines. Since people with lower levels of homoarginine are at greater risk suffering from cardiovascular disease, this finding showed that it may be possible to improve heart health through dietary changes that affect the gut.

Changes that affect the intestine

O results suggest the possibility to improve the risk of cardiovascular disease through dietary changes that affect the gut. Additionally, this work may help identify other foods or supplements with similar nutritional benefits. Although scientists know that certain foods improve heart health, many questions still need to be answered, such as how this occurs and what other foods exist that may reduce the risk cardiovascular.
