Studies have found that eating more fruits and vegetables and less heart disease

Researchers in Canada and the United States found that some people carry genes that make them vulnerable to heart disease Eating more raw vegetables and fruits can "turn off" the gene expression, reducing the risk of heart attack or stroke The researchers analyzed the effects of different diet types on the heart health of more than 27000 Europeans, South Asians, Chinese, Latinos and Arabs Among the subjects, some carried chromosome 9p21 single nucleotide polymorphism, while others did not Previous studies have shown that the single nucleotide polymorphism of chromosome 9p21 predicts the susceptibility to cardiovascular disease, which is applicable to multiple individuals around the world The researchers found that among people with chromosome 9p21 single nucleotide polymorphisms, the risk of heart attack in people with "prudent diet" was comparable to that in people with low susceptibility to heart disease determined by genes The so-called "prudent diet" refers to the main consumption of fresh vegetables, fruits and berries "We know that the 9p21 SNP increases the carrier's risk of heart disease, but surprisingly, healthy eating and drinking may significantly reduce this effect," Jamie Engert, a cardiovascular geneticist at Keele University in Mecca, Canada, told the Brandon sun in an interview Engert said that of the five ethnic groups, only Arabs did not have this role, which may be due to the small number of Arabs participating in the study The results were published in the latest issue of Public Library of science medicine "It's well known that eating carefully helps to avoid heart disease," Engert said, "but what's important about this study is that it shows that certain genetic variations associated with susceptibility can be weakened." "Our findings support public health recommendations that eating more than five servings of fruit or vegetables a day promotes health," said Dr Sonia Anand, of the Institute of population health at McMaster University in Canada It's not clear how food can overcome the power of genetic factors, Anand said, "but let's assume that a diet rich in fruits and vegetables, and all the good elements in it, somehow modulates the expression of this particular gene." "I think this result is significant because some people have a family history and feel that their genes can't be changed," Anand said "The results of this study send them a message that you can actually change risk factors and turn off bad genes by eating a healthy diet." "From a purely scientific perspective, it is quite meaningful to see this interaction and further study the mechanism of action in the future, because we have been looking for drug targets or ways to regulate gene expression," Anand said Judy O'Sullivan, a senior heart disease nurse at the British Heart Foundation, said the study provides insight into how heart disease risk is affected by a range of factors, as well as into how lifestyle and genes may increase the risk of disease, and the interaction between the two is "very important." "The relationship between the two is often very complex and has not yet been fully understood, but it is very simple that eating more fruits and vegetables is good for heart health," O'Sullivan said
