The elderly can eat more mushrooms

Researchers from Oxford University, UK, followed 107 elderly people aged between 61 and 87 for five years and found that many of them had low levels of vitamin B12 in their blood Those with vitamin B12 levels less than a third of the normal range were three times more likely to develop Alzheimer's, the researchers said Experts suggest that the elderly can eat more mushrooms Generally speaking, the older the body is, the less vitamin B12 is absorbed by the body, and the less resistant it is to disease In serious cases, it will cause damage to nerve cells In the past, nutrition believed that the main food source of vitamin B12 was meat and fish, and plant food rarely contained vitamin B12 In order to control blood glucose and lipid, the obese and the elderly with cardiovascular diseases often put the animal liver and the meat and aquatic products with high protein content into the "blacklist" Another part of vegetarians, also because long-term do not eat meat easy to lead to vitamin B12 deficiency Although vitamin B12 can hardly be found in most vegetables, mushroom and other fungi are abundant In particular, the content of vitamin B12 in Lentinus edodes is higher than that in meat Adults eat about 25 grams of fresh mushrooms every day, the intake of vitamin B12 can meet the standard In addition, the cellulose contained in Lentinus edodes can reduce the intestinal absorption of cholesterol Therefore, eating Lentinus edodes once a day is the best choice for middle-aged and elderly people who are worried about the "three highs" problem, as well as determined vegetarians.
