Does eating vegetables reduce your risk of heart disease? 

A recent study conducted jointly by the universities of Oxford, Bristol and Hong Kong found that eating vegetables may be good for heart health, but eating more of them is not likely to reduce the risk of heart attack or stroke. We may see a lower heart risk in people who eat a lot of raw vegetables, compared to those who eat cooked vegetables, because cooking vegetables removes important nutrients from them, such as vitamin C.

The study found that people who follow a diet rich in vegetables may consume fewer calories and less fat, and may live an additional 13 years, especially if their diet is based on vegetables and legumes, as well as whole grains, fruits and nuts.

However, relying only on a diet full of vegetables may not be enough to protect against heart disease, as heart health is usually linked to lifestyle and ways of exercising.

The study analyzed questionnaires distributed to 399,586,000 people taking part in the UK Biobank study about their diet, including the amount of cooked and raw vegetables they ate daily.

Most people confirmed that they eat, on average, two tablespoons of raw vegetables and three of cooked vegetables, which amounts to a total of about 5 tablespoons per day. By analyzing this data with their health profiles for about 12 years, the risk of dying from cardiovascular disease was about 15 percent lower for those who ate the most vegetables especially those who ate a lot of raw vegetables compared to those who didn't eat vegetables.

The study also included people's ways and lifestyles, for example, whether they smoke, or drink large amounts of alcohol, as well as their jobs, income and diet in general.

As a result, they said their study found no evidence of a "protective effect of eating vegetables" on the frequency of heart and circulatory problems.

In her interview, Dietitian Rem Raphael commented on this study by saying that a balanced healthy diet based on reducing saturated fats and increasing vegetables and fruits may be optimal for human health. She believes that the health system to protect the heart should be based primarily on increasing foods that contain omega-3, including fish, as she stresses that eating fish twice a week may protect against heart disease.

On the other hand, Rafael believes that the diet, even if it is healthy and based on mono-fats, eating nuts and using fruits and vegetables, may not be sufficient to maintain physical health, unless this health system is combined with healthy habits, including exercise, and reducing the intake of drinks. alcohol, and stop smoking, as these habits may have an important impact on overall health.

Raphael usually advises people who suffer from heart disease, or diseases related to the circulatory system, to take into account the importance of losing weight, as she considers that weight gain may also be a negative factor that affects human health.

 ***Positive Effects

In the first comment on the study, Dr. Ben Lacy of Oxford University stated, according to what was stated on the British "BBC" network, that the results of this study may be important, given the possibility of understanding the nutritional causes of cardiovascular disease, which he reiterated. Qi Fang, an epidemiologist at Oxford University, considered that this study may be the first of its kind to confirm that there is no protective effect of eating vegetables on cardiovascular health in a significant way. While the study found that eating raw vegetables can protect against heart disease, cooked vegetables did not.

***Criticisms and objections

Some experts objected to the results of the study, and found that reducing the role of vegetables in protecting heart health may be unhealthy. Professor Naveed Sattar, Professor of Metabolic Medicine at the University of Glasgow - who was not involved in the study - had a different opinion, and found, in commenting on the results of the study, that what the experts presented may provide good empirical evidence that eating high-fiber foods, Like vegetables, they can help reduce weight and improve levels of risk factors known to cause heart disease.

While the senior nutritionist at the British Heart Foundation, Victoria Taylor, said, according to CNN, that although this study found that eating more vegetables was not associated with a lower risk of heart and circulatory disease just by taking lifestyle and other factors. Keep in mind, this doesn't mean you should stop eating vegetables.

*** What are the medical advice?

According to the advice of the National Health Service in the United Kingdom, fruits and vegetables are a good source of vitamins, such as folic acid, minerals and potassium, and they contain fiber that can help maintain a healthy intestine, prevent digestion problems and reduce the risk of bowel cancer, and can also help It reduces the risk of heart disease, stroke, and some other types of cancer.

Experts advise taking several steps to include vegetables as part of their diet, including replacing one serving of meat per day with a vegetarian or grain-based choice. Experts advise that at least one meal a day contains legumes, such as lentils, whole grains or beans, which can be added to a meat-free salad, as it can help raise blood sugar levels slowly, giving the mind energy. that he needs daily.
