US media: Healthy eating not only benefits heart health but also reduces air pollution hazards
Jul 27, 2018

Reference News Network May 27 reported that the US media said that the Mediterranean diet has long been praised as a heart-healthy diet that can prolong life. Now, a new study shows that this diet can also help prevent the harmful effects of air pollution and reduce the risk of death from heart attacks, strokes and other causes.

According to the US Health Life News Network reported on May 21, the Mediterranean diet emphasizes fruits, vegetables, whole grains, beans, olive oil and low-fat protein, limiting the consumption of red meat and processed food. The researchers explained that the Mediterranean diet is rich in antioxidants that neutralize free radicals that destroy tissues and cells. Chris Lime, a Ph.D. student at New York University School of Medicine, said: "Previous studies have shown that changes in diets - especially the addition of antioxidants - can alleviate the adverse effects of exposure to high concentrations of air pollution in the short term. ”

Lime said in a press release issued by the American Thoracic Medicine Association: "What we didn't know before is whether diet can affect the link between long-term exposure to air pollution and health effects."

The report said that in order to conduct the study, the researchers analyzed data from the National Institutes of Health/America Retirement Association's Diet and Health Survey. The survey tracked 549,000 seniors in six states over a 17-year period. During this period, approximately 127,000 respondents died.

According to the extent to which the respondents used a Mediterranean diet, the researchers divided them into five groups. Using census data, investigators also estimated the extent to which respondents were exposed to certain air pollutants, including fine particulate matter, nitrogen dioxide, and ozone.

The study found that for those who had at least a Mediterranean diet, the average number of long-term exposure to fine particles increased by 10 micrograms per cubic meter, and the number of deaths due to heart disease increased by 17%. In contrast, in those who maximized the Mediterranean diet, the number of deaths from heart disease increased by only 5% in the same situation.

In the population farthest from the Mediterranean diet, the average concentration of long-term exposure to nitrogen dioxide increased by 10 ppm (ie 10 per billion), and the number of deaths due to all causes increased by 5%. In contrast, among those who used the Mediterranean diet to the greatest extent, the number of deaths in the same situation increased by only 2%.

According to the report, it should be noted that this study does not prove that the Mediterranean diet can resist air pollution, but only proves that there is a certain connection. But researchers say the diet can protect a large number of Americans from the harmful effects of the above air pollutants.
