In our life, there are many kinds of health care products and propaganda methods, and their efficacy is also blown to the ceiling. Students and middle-aged and old people are the most easily deceived people. They are often fooled by a product that exaggerates its efficacy and spend a lot of money. Next, I'll make up some useless food for you. Don't be fooled.
1. Protein powder: no need for healthy people
These years, more and more fat paper, and at the same time, thin paper will never eat fat. It's so skinny that I can't see any blood. As a result, some businesses said that protein should be added. Then, the protein powder began to sell.
Actually:
A jar of 400g protein powder costs 2300 yuan. Healthy adults need 1g of protein per kilogram of body weight every day, which can be met by normal diet. Therefore, normal diet of healthy people do not need additional protein powder.
2. Grape seed: the concept of business stealing
The grape seeds that have been spit out at ordinary times are also advertised by businesses as anti-cancer, anti-oxidation and anti-aging. All kinds of "grape seed oil" and "grape seed powder" are also selling hot.
Actually:
There are a lot of experimental data about the inhibition of cancer cells by grape seed extract, but the premise is very clear - "in vitro experiment can inhibit cancer cells".
"In vitro experiments" can only show that further research can be carried out on specific cancer cells, and there is no evidence that grape seed extract can inhibit cancer cells in vivo.
3. Organic food: just psychological comfort
Every time you go to the supermarket, someone will sell you all kinds of 'green vegetables' and' organic rice ', which sounds very high-end and healthy. Coupled with the' natural pesticide free 'on the package, it's really attractive. But in fact, 'expensive' is not necessarily 'good'.
Actually:
Earlier, consumer associations had conducted sampling inspection on organic food and green vegetables on the market, respectively testing pesticide residues, heavy metal pollutant limits and physical and chemical indicators.
The test results are astonishing. Although the price of these so-called "organic food" green vegetables is much higher than that of ordinary vegetables, the test results of these indicators still exceed the national standard & hellip;
4. High calcium milk: no better than ordinary milk
When we buy milk, we often see high calcium milk, and its price is much higher than ordinary milk. Nutritionists said that the so-called high calcium milk is only artificially added some calcium during production, which makes the calcium content in milk higher.
Actually:
The calcium in common milk is calcium lactate, which has a high absorption rate, while the calcium carbonate in high calcium milk is artificially added, which has a low absorption rate. Drinking high calcium milk does not mean that it can completely absorb the calcium contained in it. In fact, ordinary milk is enough!
5. Fish oil: fish is enough
Every major health care products counter, fish oil is always big flower Kui. Really so good?
Actually:
Since fish oil comes from fish and the purification of fish oil is not stable, isn't it more direct and effective to eat fish? The answer is yes.
In addition to fish oil, fish also provides high-quality protein, vitamins and minerals and other trace elements. The saturated fatty acids in fish meat are very low, which is also excellent for cardiovascular health.
6. Sea cucumber: no better than egg
Just sit in the restaurant and open the menu. There is always a sea cucumber, which lures you. What's more, the boss said, the protein content of this product is old and high. If you want to eat well and eat healthily, you can't help but order. But it's too expensive.
Actually:
The value of sea cucumber is protein, but its protein content is very high, but its quality is not high. Protein has high quality and low quality, and its quality is mainly judged by the absorption rate of amino acids in protein.
Egg is the most suitable food for human amino acid pattern, so egg is a perfect source of protein. It's better to eat two eggs a day, with some bean products and vegetables. The latter's protein is much better in quality and quantity.
