High calcium milk more calcium supplementation? Can soda biscuits nourish the stomach? Don't spend this money

Now, because people are paying more attention to health, the so-called "healthy food" in supermarkets has also increased, high-calcium milk, health care rice... But the truth is: most of us are deceived by the name, don't spend this unjust money!

1. High calcium milk is more calcium supplemental?

With the improvement of people's awareness of calcium supplementation, high-calcium milk has become people's first choice. Many people will think, the same milk, is not the high calcium milk more calcium than ordinary milk?

Wang Xufeng, president of the Capital Health, Nutrition and Gastronomy Society, said in an interview with Health Times in 2017 that the calcium in ordinary milk is calcium lactate, which is very easily absorbed by the human body. In high-calcium milk, calcium carbonate or other calcium is fortified, and the absorption rate will be slightly lower.

The calcium content of high calcium milk is indeed higher than that of ordinary milk, but the calcium content of milk itself is very rich, and the increased amount of "calcium" will not cause a huge difference, and most of the absorption effect is not as good as the calcium of milk itself.

Wang Xufeng reminded that if you buy high-calcium milk with a higher price in order to pursue more calcium intake, it is better to drink more ordinary milk, not only the calcium content is high, but the intake of other nutrients will also increase. ①

2. Health care rice is more nutritious?

Selenium-rich rice, high-calcium rice, bamboo fragrant rice, apple rice, etc., these are the so-called health care rice on the tall. The price of these rice is more expensive, and some even as high as 20 to 30 yuan a catty.

Wang Guizhen, a national first-class nutritionist and president of the Weifang Dietitians Association in Shandong Province, pointed out in a health times article in 2018 that the various effects of health care rice promoted by businesses are actually similar to the principle of fortified flour.

For example, selenium-rich rice is artificially added selenium to rice. As long as the selenium content in rice exceeds 40 μg/kg, it can be called "selenium-rich rice". The Chinese Nutrition Society recommends that normal adults should consume 50 micrograms of selenium per day to meet the needs of the human body. And the most important food source of selenium is not plant food, but seafood and animal foods, such as meat, liver, kidneys and so on.

We eat rice and satisfy in order to meet the human body's needs for staple foods, which is the biggest role of rice and rice. If you want to eat rice healthily, there is no need to be superstitious about "health care rice". According to the "Dietary Guidelines for Chinese Residents", rationally arrange their own dietary structure, ensure that food diversification, you can obtain more nutrients. ②

3. Can soda biscuits nourish the stomach?

Some elderly people like to eat soda biscuits, thinking that this can nourish the stomach, and many parents also like to buy food for their children. The idea that soda biscuits can nourish the stomach is deeply rooted in people's hearts, but the truth is not.

Wang Nan, a senior national food inspector, pointed out in a health newspaper article in 2015 that in terms of composition, soda biscuits do contain alkaline sodium bicarbonate, which can be neutralized with the stomach acid of people with strong gastric acid secretion, alleviating symptoms such as "heartburn" caused by excessive gastric acid secretion. But this effect is not as magical as imagined.

In fact, the effect of stomach acid in soda biscuits is similar to that of ordinary steamed bread. More importantly, the crispy soda biscuits have a considerable fat content, most of the products have a fat content of 20% to 30%, if you mistakenly think that it is a healthy biscuit and eat a lot, the consequences can be imagined. ③

4. Children's food is more suitable for children?

In recent years, a large number of foods with the word "children" have gradually emerged on the market, such as children's dumplings, children's milk, etc., and their prices are often relatively high among similar products.

Liu Shaowei, a professor at the Food and Drug Regulatory Research Center of East China University of Science and Technology, pointed out in a health newspaper article in 2019 that most of the "children's food" is just a gimmick, and the nutritional components in the products are not much different from ordinary foods, and there is no saying that it is suitable for children to eat and promote children's growth and development.

Among them, the more typical is children's soy sauce, which focuses on the concept of low sodium and low salt and increased trace elements, saying that it is more suitable for children to eat, and the price is nearly 3 times that of ordinary soy sauce. However, after carefully reading the ingredient list, you will find that the sodium content in some children's soy sauce is indeed slightly lower than that of ordinary soy sauce, but some of the sodium content is higher than that of ordinary soy sauce.

In addition, in order to attract the attention of children, some products marked "children's food" will add additional coloring and more sugar and salt to cater to children's preferences, which is not very recommended. Therefore, there is no need to specifically buy so-called children's food, and we must be optimistic about nutrition labels. ④

5. Walnut drinks are more nutritious?

A 240 ml can of boutique "X walnuts", the drink nutrition label indicates that each 100 ml contains 0.6 grams of protein, from which it can be inferred that a total of 1.44 grams of protein in a can.

Wang Yueqiu, a national second-level public nutritionist, said in an interview with Health Times in 2013 that a medium-sized walnut is about 12 grams, and the weight of walnut kernels accounts for 43% of the weight of walnuts, calculated that walnut kernels are about 5.16 grams, and it is known from the query in the "Chinese Food Composition Table" that the protein content in walnut kernels is 14.9%, so the protein content in a walnut is about 0.77 grams.

There are only 1.44 grams of protein in a can of "X walnuts", which is calculated according to the protein content, and the nutrient content is less than two walnuts.

Moreover, the nutritional ingredient list of the product does not indicate the ingredients and related contents with special effects, from this point of view, it is an ordinary drink. And this kind of walnut milk after processing such as additives and flavors should not be drunk more, if you want to supplement nutrition, it is better to eat fresh walnuts directly. ⑤
