4 misunderstandings about calcium supplementation for pregnant women

　　Myth 1: The more calcium, the better

　　The "Dietary Reference Intake (DRI) for Chinese Residents" formulated by the Chinese Nutrition Society states that the tolerable maximum intake of calcium for adults is 2,000 mg per day. This intake is not the recommended standard intake. Generally speaking, the recommended intake for adults is 800mg per day, and generally consume at least 500mg of calcium from the diet. The closer the calcium intake is to the tolerable maximum intake, the more harmful healthy the greater the risk. Excessive intake of calcium may interfere with the absorption and utilization of other trace elements by the human body, and may also increase the risk of kidney stones. That is to say, more nutrient intake is not better, lack of it is bad for health, and excess may also be harmful to health. Generally speaking, the body's demand for calcium can be basically met through a daily balanced diet and increased intake of dairy products. Therefore, more calcium supplements are not always better.

　　Myth 2: Taking calcium tablets is the best way to supplement calcium

　　Among the natural foods we consume every day, there are many that can achieve the purpose of increasing calcium, such as dairy products, soy products, etc. Compared with calcium tablets, these foods are cheaper and more convenient to eat, so they should be the first choice for calcium supplementation. In addition to daily food adjustments, if the body's needs cannot be met, the use of nutrient supplements or fortified foods is also one of the ways to solve insufficient micronutrient intake.

　　Misunderstanding 3: Believing in exaggerated claims in advertisements

　　In order to increase product sales and expand popularity, some manufacturers include unrealistic and exaggerated words and data in their advertisements. Experts say: Under normal circumstances, the absorption rate of calcium by the human body is about 30%. This is obviously very different from the 90% absorption rate advertised in some commercial advertisements. Some manufacturers also write experimental results obtained on animals in product instructions. To deal with these, consumers need to have correct and objective judgment. They should not follow the trend or blindly follow the products. They should consciously accumulate more medical knowledge. common sense is very necessary.

　　Misunderstanding 4: Confusing the concepts of health products and drugs

　　From the perspective of national regulatory requirements: health food is food and is not allowed to have any toxic side effects, while drugs are allowed to have toxic side effects. The medicine is in disease Food eaten under normal conditions can be consumed by citizens on a daily basis. In terms of time, medicines are taken occasionally, while food can be taken frequently. However, it is worth noting that the dosage of some nutrient products is allowed to be larger when they are batched into drugs. Long-term intake of certain nutrients in large doses may be harmful to health. 》》》 How should pregnant women prevent and treat vaginitis?
