Take a few small pills to keep fit. Is IQ tax charged？
A Fang (a pseudonym) after 90 often feels tired. Last year, on the recommendation of a friend, an online consulting agency of nutrition collocation in personal tailor prepared some health products for him. "It’s a WeChat applet. It took a few minutes to do the questionnaire. According to the results, the platform gave me some health care products, including seaweed oil, vitamin E and other 5-minute pills." Five small pills a day, A Fang feels that the price is not expensive, and the first order can’t reach 700 yuan. Three months’ worth, and I haven’t finished eating for half a year. Although he didn’t see the effect of these nutritional supplements, he was psychologically satisfied.
A Fang’s friend left a message for the qianjiang evening news Hour reporter, trying to confirm whether this little pill is reliable or not. "Is this an IQ tax?"
Nutritionist’s statement:
The conclusion of the questionnaire is unscientific.
This online consulting organization of nutrition collocation in personal tailor takes WeChat as the main channel, carries out brand promotion through WeChat official account, and advertises in the circle of friends based on big data, and then uses the strong sociality of WeChat to push the brand to a wider audience. At the same time, it also opened up channels such as Tik Tok, Xiaohongshu and Tmall to capture the youth market.
The founder of the agency mentioned in an interview with other media that "some people can’t keep eating vegetables and exercising every day. He must smoke, drink and eat fast food in his life, then we can recommend him to take some extra vitamins with the goal of making people healthier. "
The reporter also spent a few minutes making a questionnaire, including topics such as eating habits and lifestyle. The questions are many and detailed, and some are indeed subjective.
Finally, the platform for reporter personal tailor’s plan requires five kinds of drugs, with a quantity of three months and a cost of more than 600 yuan.
Is the vitamin supplement obtained by this consultation reliable?
After reading the complete questionnaire, Lu Yanxuan, a nutritionist at the Second Hospital of Zhejiang University, said: "The questions involved in the questionnaire are quite reasonable, and there is no problem from the evaluation point of view, but the conclusions drawn through these questions are not enough evidence."
In other words, these surveys can’t determine what your body needs, and the conclusions drawn from them are too one-sided. For example, fatigue means that the body lacks some nutrients, which is unscientific.
In her view, as long as you follow the Dietary Guidelines for China Residents (2022) issued by the China Nutrition Society on April 26th, 2022, you can achieve a balanced nutrition.
"Many health care products, including nutritional supplements, are controversial. Whether they can prevent and alleviate diseases, there is no direct and specific conclusion." Lu Yanxi said.
In fact, in the usual diet, nutrients are enough. For example, vitamin e exists in our usual cooking oil; Vitamin A can be taken from meat, eggs, milk and dark vegetables.
Just eat reasonably at ordinary times.
Special people should supplement nutrients.
Lu Yan-fung’s conclusion is that a reasonable diet can satisfy nutrition and maintain good health, and no additional supplements are recommended.
For example, too much calcium intake will interfere with the absorption of zinc and iron; Vitamins A and D are fat-soluble vitamins. If they are not easily metabolized, they may accumulate in the body and even have the risk of poisoning.
"The dosage standard in China is different from that in foreign countries, so foreign health care products may not be suitable for Chinese." She said that even the most harmless probiotics that can regulate the intestines, everyone has different reactions to it, so you can’t blindly follow suit.
But some special people really need to supplement nutrients, so they can eat some properly.
Pregnant women, nursing mothers, young children, the elderly, etc., due to the high demand for some nutrients in special physiological periods, should often consult nutritionists, nutrition experts or doctors (hospitals, health centers) to make reasonable nutritional conditioning to ensure the nutritional needs in special physiological periods.
The means of nutritional conditioning include diet, nutrient supplement, reasonable exercise and other measures.
On the whole, Lu Yan-fung suggested that you should not eat health care products to supplement nutrients at will, and a reasonable diet can fully meet the nutrition. If you really want to supplement it, you need to supplement it scientifically and effectively under the guidance of professional doctors.
