Speaking of health care products, let's talk about diet first.

One: diet:

You should be vegetarian, because vegetables and fruits are rich in vitamins and minerals, and also rich in dietary fiber, which can not only prevent constipation, but also reduce the damage of harmful substances in feces to the intestinal wall and prevent intestinal cancer. In addition, most vegetables and fruits are alkaline foods, while generally high-protein foods are acidic foods. In people's stomachs, foods such as meat, rice and wheat often produce acidic reactions after digestion, which requires vegetables and fruits to neutralize and maintain the acid-base balance in the body. The ancients put forward the idea of "five dishes as stuffing" long ago, which shows that vegetables have the functions of "filling" and "dredging" the digestive system. Therefore, to have a good appetite and a healthy digestive system, we must often eat more fruits and vegetables.

Although eating more meat will lead to many diseases, it doesn't mean that we can't eat any meat at all, because animal protein in animal meat and poultry meat is an essential nutrient for human body. Not long ago, European scientists concluded that people often eat red meat (beef, pork, mutton, etc. ): Eating red meat regularly will increase the risk of intestinal cancer. Therefore, while ensuring the acid-base balance, it is best to use white meat such as fish, chicken and duck instead of red meat. For those who prefer meat, Professor Li stressed that when eating foods rich in cholesterol, you must mix some vegetables, fruits and beans to increase the excretion of cholesterol, reduce the synthesis and absorption of cholesterol in the body and avoid the occurrence of atherosclerosis.

Starch food mainly inhibits intestinal cancer in two ways: first, after starch enters the intestine, it helps to increase feces, promote colon excretion and accelerate the excretion of carcinogenic metabolites. Secondly, starch can produce a large number of butyrate through the action of intestinal fermentation enzymes. Experiments show that butyrate is an effective cancer cell growth inhibitor, which can directly inhibit the proliferation of bacteria in the large intestine and prevent the generation of cancer-causing cells on the inner wall of the large intestine.

How to choose starchy food in life? For busy office workers, roughing whole grain foods such as cereal bread in supermarkets is the first choice. Pay attention to recognition when buying cereal bread: if the first ingredient in the ingredient list is cereal, it means that its cereal content is really rich; If the cereal ingredient ranks behind other ingredients or sugar, it means that there are not many cereal ingredients in this food. Another way is to hold the bread in your hand. If you feel that bread is dense and has obvious grains, it is bread rich in grains.

Besides cereal bread, rice made of noodles, bean jelly, pancakes, steamed dumplings and buckwheat is also a good choice. Five-grain porridge rich in B vitamins and vitamin E, such as Laba porridge, Babaolian porridge and lotus leaf porridge, is more suitable for middle-aged and elderly people.

Second, the choice of health care products for the elderly:

Health care products have health care function, but eating health care products without scientific knowledge will not only have no health care effect, but also damage the health of the elderly. If you don't take health care products as needed, it will lead to some functional disorders and other side effects. For example, vitamin A, which is not easily excreted, may sometimes be poisoned. Some Chinese herbal medicine supplements, if eaten too much, will cause poisoning, liver damage and other consequences because of their medicinal properties. Some health care products add a certain amount of hormones, so users must pay attention to the overall balance. Too many hormones are very harmful to health.

Health care products are not for the purpose of treatment, but for preventing diseases and maintaining health, and are suitable for specific people, such as sub-healthy people and people with vitamin deficiency. Therefore, health care products can not be used as a substitute for daily diet, and the elderly should pay special attention. Therefore, it is suggested that the elderly can take some calcium-supplementing drugs and health products. If it is iron deficiency anemia, in addition to increasing the absorption of iron from food, they can also eat some iron-containing health products. However, iron supplementation should be carried out under the guidance of a doctor, because iron is not easy to be excreted, and excessive iron supplementation will lead to iron poisoning.

Check your health before choosing health care products.

What should the elderly choose health care products based on? Although taking health care products does not require a doctor's prescription, anti-aging health care products can be taken by ordinary elderly people. However, it is best to choose the appropriate health care products according to the comprehensive physical examination of the elderly and comprehensive analysis.

The elderly should have a physical examination every spring and autumn, and it is best to consult a nutritionist before taking health care products. If you are worried about the lack of some trace elements in the blood, you can go to the nutrition department of the hospital for a hair test or blood test. According to the test results, see what is missing and how much is missing, and the doctor will give an appropriate supplementary plan. After adjusting for a period of time, test the elderly again. If the index reaches the standard, don't make it up. Because further tonic will cause other discomfort.

Old people can take some health care products, one is anti-aging health care products, whose main function is to resist free radicals. Such as vitamin C, vitamin E, lycopene, etc. The second is health care products that improve immunity and promote metabolic function. The third is health care products that improve intestinal function, such as lactase. He especially reminded that a health care product should not be eaten for too long, because health should be "balanced". When choosing health care products, we should pay attention to the following six steps: first, recognize the attributes, that is, see if we belong to a specific group listed in a health care product. Second, find your own needs. Third, understand the effective ingredients (efficacy ingredients) in the product, and don't divert your attention because of the efficacy propaganda in the advertisement. For example, there are forty or fifty kinds of health care products to regulate sleep, such as melatonin, which has different names and different propaganda, but its active ingredient is melatonin. Fourth, pay attention to the production unit and the approval number to see if there is the word "construction". 5. See if there are "suitable people" in the precautions in the product manual. If there is no such explanation, at least it can be judged that this health care product is irregular. Sixth, some health care products will also list "not suitable for people", so be sure to read and compare them carefully before buying.
