Dr. T. Collin Campbell: Lifelong Professor at Cornell University, known as the “World Nutritionist Einsteinâ€.
Moderator (He Bo): Prof. Chen, we happen to have a live netizen who would like to ask you a question - “Academician Chen Hello, I have read a theory that China’s scientific diet: five grains, five animals The right amount, not to lose beans, vegetables, miscellaneous vegetables, supplemented with fruits! - This is the theory of the whole nutritional structure balance. We do this, our nutrition is enough?"
Chen Junshi: Yes, this is an ancient Chinese saying. Well, according to Professor Campbell just now, recent scientific research has elaborated on such a theory because it does not see which one is the main one, the grain is inside, the fruit is inside, the vegetable is inside, and the chicken fish egg Milk is all in there. There are so many foods in our world. In the end, we have to choose what kind of reasonable collocation. According to what we talk about today, we still have to choose more plant foods in such a theory. There are vegetables, fruits and beans outside the grain.
Moderator (He Bo): If you reach such a balanced diet you also need to add some nutritional supplements such as some of today's health products including vitamin supplements.
Chen Junshi: In principle, our nutritionist will always use reasonable food as the first one. This is what Professor Campbell said. If there is a good mix of food, vegetables, fruit, and beans, it counts. With thousands of nutrients inside, nutrition is complete. Under normal circumstances does not mean that you must use nutrient supplements, let alone health foods, that is another kind of thing. But I think we can't say that we have to kill nutritional supplements on one stick, because people have different situations. For example, people may need more iron when they are pregnant. This is a special physiological period.
Some people may lack something because of some special circumstances, lack certain micronutrients or vitamins, then he may need to add something. We generally do not claim to rely on vitamins and minerals supplements to ensure your nutrition is adequate, but rely on the diversification of food with a reasonable mix.
Campbell: I would like to talk about the fact that vegetarianism can lead to weakness. In history, we often associate physical weakness with vegetarianism. This is mainly due to the fact that most people who were vegetarians in the past were relatively poor and could not afford meat. At the same time, people may not notice that public health conditions are often poor in poor areas. Therefore, because of these reasons, it is easy to get sick and easily weakened. But now the situation is different. In modern countries, the intake of a variety of vegetarian plants and plants will not cause monotonous malnutrition. It should be very good.
At the same time, I would like to supplement nutritional supplements, that is, vitamins and health supplements in China. In the past few years, there have been many studies that prove that some nutritional supplements are useless and some are even harmful. In general, nutritional supplements are an element. In a tablet, it looks as if it can supplement something, but it's not nutrition. It's drug medicine because our body is very complex. A comprehensive system of supplements, which actually supplements one of them is ineffective.
