Editor Lin Xinjie With the increase of age, in addition to changes in appearance, the body's function will gradually decline, and low metabolism and lack of vitality may be the result of aging. However, recent studies have pointed out that some things can indeed reverse the traces left by time, improve metabolism, improve insulin sensitivity and make people full of energy. Moreover, such anti-aging effect does not need to buy expensive skin care products, because the real anti-aging nutrition comes from diet, such as eating avocados, edamame, cauliflower, green tea, orange fruits and vegetables, and following the Mediterranean diet. These are simple anti-aging steps! American research: Supplementing nicotinamide single nucleotide (NMN) is helpful for anti-aging. In a study conducted by Washington University School of Medicine in St. Louis, after drinking water containing nicotinamide mononucleotide (NMN), the metabolic ability and energy retention ability of aged mice were improved. In addition, compared with the control group that did not take this ingredient, the mice that drank NMN ate more and gained less weight. NMN is a substance that animals can make by themselves. In the human body, a protein named sirtuin can inhibit some gene effects, including genes related to aging. In this process, NMN is needed as fuel. All cells in the body can make NMN, which will be converted into other molecules, get energy from food and turn it into a form that can be used by the body. The results also found another interesting fact: the improvement effect of NMN seems to be unable to play a role in young mice. The researchers believe that this is because the supply of NMN in animals will gradually decrease with age, so older mice will need to supplement NMN. Although it is difficult for us to replicate the experimental results through diet, researchers believe that long-term intake of fruits and vegetables rich in NMN may have cumulative anti-aging effects. Therefore, the researchers suggest that the ratio of fruits and vegetables per meal should be between 1/4 and 1/2. The foods rich in NMN include tomatoes, avocados, edamame, cauliflower, cucumber and cabbage. The NMN is a derivative of nicotinic acid (vitamin B3). Kristi King, a registered dietitian and spokesperson for the Nutrition and Diet Association, pointed out that vitamin B is very important for energy production and cell metabolism, while foods rich in niacin include peanuts, mushrooms and green tea. In addition, Torey Armul, a registered dietitian and spokesman for the Nutrition and Diet Association, pointed out that carotenoids commonly found in orange and yellow fruits and vegetables can increase the vitality of the skin and prevent collagen from decomposing in situ. This kind of food includes oranges, pumpkins, carrots, orange peppers and so on. In addition, ellagic acid contained in fruits and vegetables rich in antioxidants, such as pomegranate and raspberry, has also been found to reduce the decomposition of collagen in animal studies. In recent years, the Mediterranean diet, which is gradually known by people, has been recognized by many studies for its protective effect on the brain, which can reduce the incidence of cognitive dysfunction and help reduce the risk of Alzheimer's disease. In addition to all kinds of fruits and vegetables, the Mediterranean diet also recommends olive oil, nuts and oily fish rich in omega-3, which helps to reduce the chronic inflammatory damage that often occurs during aging. In addition, moderate drinking of red wine also helps to maintain brain function. vulnus
