First, protein powder. If you are a fitness person, then you must be familiar with the term protein powder. People who exercise often buy protein powder in order to better supplement protein and lose weight, gain muscle and shape. However, if you don't want to lose weight and shape, but want to take protein powder with health care function, then I can tell you for sure that it is useless. The main component of protein powder is protein, which has a single structure and cannot prevent diseases, let alone cure diseases!
Second, fish oil. In today's health products counters, fish oil can be sold at high prices. Fish oil is claimed by merchants to promote children's eyesight and improve children's intelligence, but in fact, if you ask merchants to produce such experimental proof, they can't produce it. In the current research, there is no factual basis to show that fish oil has such an effect. Moreover, it is worth considering that many fish oils are often extracted from deep-sea fish, which contains a lot of heavy metals, which is actually very unfavorable for children's growth.
In fact, in addition to these two kinds, there are many health products that make money under various flags, such as barley juice and Julia juice, enzymes that can reduce blood fat and blood pressure, and so on. These things actually have no scientific basis to prove their reliability. Therefore, if you want a healthy body, it is best to eat regularly and go to bed early and get up early.
