BBC reported that a large study by the UK Biobank of the United Kingdom from the Universities of Oxford and Bristol, England. and the Chinese University of Hong Kong The survey gathered nearly 400,000 people who answered a questionnaire regarding their diet, including their daily intake of cooked, cooked and raw vegetables.
from the average The respondents said they ate 2 tablespoons of raw vegetables and 3 tablespoons of cooked vegetables for a total of 5 tablespoons a day. hospitalization or death over the next 12 years

As a result, the researchers said The study found no evidence of The “preventive effect of vegetable consumption” on the frequency of heart and circulatory problems occurred.
Dr Ben Lacey, from the University of Oxford, said: “This is an important study with implications for understanding dietary causes of cardiovascular disease (CVD).”
But Prof. Naveed Satta, Professor of Metabolic Medicine at the University of Glasgow said there was good experimental evidence that Eating high-fiber foods, such as vegetables, can help you lose weight and increase levels of risk factors known to cause heart disease.
Prof. Satta said that The conclusions of this study can be debated. And should not modify the old recommendation to eat at least 5 portions of fruits and vegetables a day.

Why eat 5 portions?
- According to the UK National Health Service (NHS), fruits and vegetables are good sources of vitamins like folate and minerals like potassium.
- Both contain dietary fiber that helps keep the intestines healthy. prevent digestive problems and reduce the risk of colon cancer

- Fruits and vegetables contribute to a healthy, balanced diet.
- and are often low in fat and calories (If not deep-fried or grilled in a lot of oil)
Other experts say that measuring the amount and type of food that people eat over the years to study the impact on disease risk Prof Janet Cade of the University of Leeds, for example, says the credibility of the findings by asking simple questions must be questioned. Respondents were expected to show average consumption figures.
The study, published in the journal Frontiers in Nutrition, says that people who eat more raw vegetables may have a lower risk of heart disease. This is because cooking vegetables removes important nutrients such as vitamin C.
Cooking oils and fats may increase sodium and fat consumption. which is a known risk factor for heart problems People on a diet high in vegetables may consume fewer calories and fat. while consuming more vitamins and anti-oxidants which can prevent damage to cells
