It has been pointed out in a popular medical science article. Vitamins do not eat more and more supplements, so do not take single-dose supplements, such as vitamin E, calcium tablets, etc., but you can eat one multivitamin every day, which is safe and practical.
Is it true that multi vitamin are good for health ?
However, there are nutrition experts who have raised the issue of buttocks, and even eating a multivitamin every day may cause problems.
Because the doses of vitamins and minerals in certain multivitamins are too high to exceed safe values, and more and more studies have pointed out that high doses of vitamins are not good for health and disease prevention, but will increase the risk of certain diseases. .
For example, several large foreign studies recently pointed out that people with high levels of vitamin A in the blood have a higher risk of osteoporosis. In addition, studies have found that excessive intake of vitamin A can double the risk of fractures. and. The vitamin A we take in will accumulate in the body, unlike water-soluble vitamins (such as vitamin B complex and vitamin C) that can be excreted in the urine.
According to the “Safe Intake Limit” of the National Academy of Sciences, the daily intake of vitamin A for adults, including food and supplements, should not exceed 3000 micro grams in total. However, in some foreign multivitamins, the single vitamin A dose is as high as 4500 micro grams, which has exceeded the safe intake limit.
In addition, foreign studies have also found that certain antioxidant vitamins, such as vitamin C, when taken in high doses (over 500 mg) will turn into pro-oxidants, increase the body’s oxidative stress and damage cells.
Another study that has proven that excessive intake will increase the risk of heart disease and cancer is the mineral “iron.” Adult men under the age of 50 need to consume 10 mg of iron per day, while women need 15 mg of iron. Those over 50 years of age, regardless of gender, reduce it to 10 mg per day. As for the upper limit of intake, it is 40 mg.
Glasses of water you need to drink every day for Vitamin
All parts of the human body contain water, and the younger the age, the more water in the body. The water content of the fetus at two months is as high as 97%, the water content of newborns can reach 80%, and the water content of adults is about 58% to 67%. The water content of ordinary men is 60%, while that of obese men is only 43%. When the body lacks 10% of water, physiological functions can be disturbed. When the body loses 20% of water, it may cause death. Therefore, there is a saying that “you can not eat for a day, but not drink water for a day”.
A healthy adult should drink 1500-2000 ml a day. But specifically, an adult weighing 60 kilograms needs 2.5 kilograms of water per day, which is equivalent to 40 grams of water per kilogram of body weight. Infants need more, generally 3-4 times that of adults, that is, every day. A kilogram of body weight requires 120-160 grams of water per day.
There are three sources of body water. The first is liquid food, such as drinking water, beverages, soup, etc.; the second is solid food, such as rice, vegetables, fruits, etc.; the third is water produced by oxidation of organic matter in the body. The amount of water produced per 100g of carbohydrates when oxidized is 60 mg, the amount of water produced per 100g of protein oxidized is 41 mg, and the amount of water produced per 100g of fat oxidized is 107 mg. The water produced by the oxidation of organic matter in an adult’s body is about 300′ grams per day.
There are four ways to excrete water in the body. The amount of urine excreted is about 1400ml, the moisture excreted by exhalation is about 500g, the moisture excreted by sweating is about 500g, and the moisture excreted by stool is about 100g. The total amount of “out” and “in” between the two is in a dynamic equilibrium state, so that normal water metabolism in the body can be maintained.
If an ordinary teacup has a water capacity of 250 ml per cup, a person drinks 6 to 8 cups of water per day. This standard is for the average person. How many glasses of water each person should drink every day depends on each person’s specific situation. Everyone should carefully pay attention to the feelings in their body, and gradually master when they want to drink water and how much water they want to drink in a day, so as to have “self-knowledge”.
At present, some conditions should be corrected. For example, some people drink a lot of drinks while eating, and as a result, saliva is diluted and gastric juice is also diluted, causing indigestion. If some people are accustomed to eating too much MSG and too much salt, resulting in dry mouth and tongue, they want to solve it by drinking more crystals. In fact, it can’t be solved. Therefore, in addition to the habit of drinking water every 2-3 hours during the day, the diet should be kept as light as possible, and salt and MSG should be used less.
Experts believe that drinking water or drinks (such as juice and soup) half an hour to one hour before meals can stimulate appetite and increase appetite. Someone suggested drinking tea after a meal. This is incorrect. It is fine to rinse your mouth with tea after a meal, but drinking tea immediately after a meal will affect the digestion of food.
