First of all, I don't know if you want to know "what's your dialectical view on this slogan" or "what's your dialectical view on eating health care products". If it is the former, I'm sorry, just stating the facts, because these five things (in fact, there are more than five vitamins alone, and we just follow them here) are really good for the human body, and they are all essential nutrients for the human body. But everyone's situation is different, so we can't generalize. It is not correct to impose the pre-distribution ratio on everyone. Because the premise of this advertisement is that "although users lack nutrients, the proportion of each nutrient is not unbalanced". But in fact, more often, people tend to have a partial eclipse, which leads to nutritional imbalance, and one is lacking and the other is not lacking. For example, people who like to eat meat are not short of iron and zinc, but too much fat will hinder the absorption of calcium (because of saponification), and too much protein will also accelerate the excretion of urinary calcium. This kind of people should supplement "calcium" or "calcium-iron-zinc combination" (calcium, iron and zinc are antagonistic to each other, and calcium supplementation will reduce the absorption of iron and zinc, which is caused by preventing others from supplementing too much calcium. (Among natural substances, except vitamin B and vitamin E, others are the most tolerant, and they will be poisoned if they are supplemented too much. Eating too much VC will lead to kidney calculi. )
If it is the latter question: health care products are not omnipotent, but they are not a scourge. Then let's take vitamin C (replaced by VC) as an example: many people say that I usually eat more fruits and vegetables and don't need to supplement VC. But have you ever thought that NPK fertilizer is used when planting vegetables and fruits? The function of these fertilizers is to make plants grow bigger in a short time, so that they can sell at a good price. But the VC in plants is synthesized by plants themselves, and the rate of synthesis is limited. The VC that plants can accumulate in a certain period of time is a constant value. Then, the synthetic amount of VC remains unchanged, while the volume of plants is increasing, which will only lead to one result: the density of VC in the food we eat is decreasing. This is our present situation: we eat the same amount of food, but get less nutrition than before. Then these insufficient parts can only be supplemented by health care products.
Therefore, if you can eat truly natural food without artificial ripening, then the nutrients in it can completely meet the needs of the human body, so you don't need to eat health care products; But if this condition is not met, then the missing part can only be supplemented by other means.
Sorry, some technical terms may be difficult to understand. But I hope it helps you. National senior public nutritionist.
