What is health care or health food? It is actually just a good wish of people. And the real world, there is simply no such some east. That is: what is useful is called resources, what is not used or exceeds the amount, and what is good again is also garbage or disease-causing factors. As if the table is not good if it is fast, slow is also a problem, how to dial is a matter of judgment. Or just in terms of a single food is not going to have such wisdom, despite the fact that some foods claim to regulate in both directions. Therefore, there are only scientific and rational health care methods in the world, but there is no such thing as health care or health food. Or even if some foods have functions, there are pros, cons, nutritional, non-nutritional and other food concomitant components, and as foods, they are often eaten together by the user, rather than or hardly using one or some of these components alone. Therefore, it is best to figure out the pros and cons before using. Otherwise, it will only be the opposite of what you want. That is: any food or food ingredients have two sides, the most important of which is the concept of quantity. Eating less or eating more can be bad. For example: diabetes, hyperlipidemia, obesity and its complications hypertension, cardiovascular disease, fatty liver, as well as anemia, tumors, low immune function in the elderly, etc. are all examples of not using the food and its nutrition well. Or their intake of almost any single substance is called nutrition, but the result is the appearance or occurrence of disease. Therefore, there is a way to identify the true from the false. Namely, anyone who only tells you more or less, not a certain amount, are all liars or guys who don’t know what they are doing. Whether it is a doctor, nurse, nutritionist, health counselor, or any other person. The reason is that all nutrition and its accompanying food components are quantity-effect relationships. Therefore, more is not okay, and less is not okay. Make no mistake, the number here is not an absolute value, or something you must take to weigh your meals. It is merely an average or calculated value, generally controlled at 5% above and below can be, or can also be the average amount of all food in recent days, only do not take too long. For example: more than 3 days before it is good. Because the body’s own regulatory capacity is limited, so after a period of time to measure the weight and so on in order to evaluate and adjust. But it’s not unlimited, or whatever you want to do.
