An apple eaten by the sun is good for cardiovascular health

An apple a day keeps the doctor away from me Eating an apple a day for one month significantly reduces the level of oxidized "bad" cholesterol, or LDL, in the blood, reduces the risk of atherosclerosis and improves cardiovascular health, according to a small US study The study on reducing oxidation was led by Robert di Silvestro, a professor of human nutrition at Ohio State University The researchers recruited 51 healthy volunteers, aged 40 to 60, who were non-smoking, ate apples less than twice a month, and did not take nutritional supplements containing polyphenols or other plant extracts Polyphenol is a kind of antioxidant in apple · Summit Forum of the economic belt around the city · five concentric projects prize collection · energy saving and I action low carbon new life · the fourth Chongqing reading month activity · 2011 morning paper midsummer Life Season · ecological treasures mid autumn gifts The researchers asked 16 volunteers to eat one big apple a day, 17 to take a nutritional supplement containing 194 milligrams of polyphenols a day, and 18 to take a placebo without polyphenols The researchers found that after one month, the level of oxidized "bad" cholesterol, or low-density lipoprotein, in the blood of Apple Eating volunteers decreased by an average of 40%; volunteers taking polyphenol supplements showed similar effects, but the effect was slightly worse; placebo had no effect on the level of oxidized "bad" cholesterol in the body of volunteers In a report published in the latest issue of the Journal of functional food, more than the same researchers wrote that "bad" cholesterol is oxidized by free radicals, which is easy to cause inflammation and tissue damage "When LDL is oxidized, it is easy to cause atherosclerosis," according to Desil westero, quoted on EurekAlert, a website sponsored by the American Association for the advancement of science People eat one apple a day, and after four weeks, the oxidation degree of LDL is significantly reduced " The difference between the two groups was similar to that between healthy people and patients with coronary artery disease According to di Silvestro, the results show that eating one apple a day has a more significant effect on lowering the level of oxidized "bad" cholesterol than other antioxidants such as curcumin, green tea and tomato extracts in peppers, "and not all antioxidants have the same effect in this particular effect." The best dietary supplement researchers believe that polyphenols in apples are the main reason to help LDL resist oxidation, but when they extract polyphenols from apples, they find that the effect is not as good as eating an apple every day "We found that the polyphenol extract had some effect, but it was not as significant as eating apples directly," said di Silvestro This can be attributed to the fact that other ingredients in apples help to enhance this effect, or that the human body can better absorb the bioactive substances in food " He said that polyphenol extracts can also play a role in some cases, the first is to increase the dose, which exceeds the dose used by researchers; the second is that people who do not like apples can properly supplement The team also found that eating apples benefits the antioxidants in saliva and promotes tooth health.
