Now all major supermarkets and shopping malls have "freshly ground health powder" counters. The health powder sold is mainly made of ingredients with the same origin of medicine and food, and is ground into powder after baking or frying. The main theme is "fresh grinding, convenience, nutrition and health", which is very popular. Can "health powder" really preserve health?
Medicine and food are homologous, and everything depends on the right amount, whether it is gram or raw.
1: Health powder containing Chinese medicine raw materials should not be mixed at will.
The common raw materials of health powder are oats, red beans, red dates, medlar, poria cocos, yam, black sesame and walnut powder. According to the merchants, these ingredients are all matched according to the classic tonic formula of traditional Chinese medicine, which is more conducive to absorption after grinding into powder.
For example, Bazhen powder produced by some manufacturers is composed of Chinese herbal medicines, such as red dates for tonifying the middle, walnuts for tonifying the kidney and warming the lungs, yams for tonifying the spleen and stomach, medlar for tonifying the liver and kidney, black sesame seeds for tonifying the liver and kidney, red beans for diuresis and detumescence, and oats for tonifying the liver and stomach. At first glance, the formula does have the effects of invigorating spleen and lung, nourishing essence and blood, nourishing liver and kidney, promoting diuresis and relaxing bowels. People with deficiency of spleen and lung, deficiency of liver and kidney, and deficiency of essence and blood can achieve certain health care effect by eating it properly. However, any ingredients have taboos.
For example, red beans "produce saliva, but they are boring for a long time", and those who suffer from yin deficiency and body fluid loss should use them with caution; Jujube "eats more wind, spleen suffers from diseases", and children, postpartum, warm, summer-damp, jaundice, toxic swelling, phlegm and blood stasis and other diseases should be avoided; Eating yam alone, eating more can also regulate qi, and all diseases such as swollen poison and qi stagnation are taboo, and those who are wet or evil and stagnation are forbidden; Walnut "eats more wind, takes off eyebrows and drinks alcohol, which makes people hemoptysis".
It can be seen that the health powder containing traditional Chinese medicine raw materials can not be mixed and eaten at will according to feelings. Even traditional Chinese medicines for both medicine and food should be scientifically compatible and reasonably matched according to their medicinal properties, and at the same time, they should be treated according to syndrome differentiation, which varies from person to person, from place to place and from time to time. If you mix all kinds of herbs at will or eat too much, it may be counterproductive for some people with physical fitness.
It's just that this effect won't be as rapid and obvious as drugs, and there won't be a strong reaction in the short term, but it's not as "safe and without side effects" as advertised by merchants. In addition, the quality of traditional Chinese medicine is also difficult to guarantee.
2. It is not good to destroy ingredients.
Not conducive to preservation. Grains and beans are covered with a layer of epidermis to protect the nutrients in food. Once broken into powder, nutrients will be lost. For example, black sesame seeds, peanuts and walnuts will be slightly rancid after crushing. If the health powder is not sealed, it is easy to absorb water, agglomerate, get wet and be moldy.
After chewing and mechanical grinding of the stomach, it takes a long time to digest and absorb the food with large particles that make the blood sugar rise rapidly, and the influence on blood sugar is slow and gentle. Powdered ingredients basically don't need to be digested by the body, and the starch in them will be directly decomposed into glucose under the action of digestive enzymes, which greatly speeds up the absorption and makes the blood sugar rise rapidly.
3. Grinding is not necessarily the best way to take it.
From the point of view of nutrition, every food has its own suitable cooking method, and not all foods are easier to absorb after pulverization. For example, dietary fiber and B vitamins in coix seed are easily absorbed by human body only after hydrolysis, and porridge and soup are the best. The proanthocyanidins contained in grape seeds need to be extracted to be absorbed by human body, and the effective components cannot be obtained only by grinding. Zhang Xichun, a famous doctor, made good use of yam. He recommended: "Yam is a very common thing to eat. If you eat it as porridge, children will like it.
It can be seen that yam is the most suitable for cooking porridge. In Qing Dynasty, Yuan Mei mentioned the methods of making poria cocos cakes and Poria cocos porridge in Suiyuan Food List, which were basically fried or boiled, and were rarely eaten in the form of powder.
In theory, there is no problem in using food materials with the same origin as medicine and food, such as longan, yam, Euryale ferox, medlar, jujube and walnut, as auxiliary health food. However, some foods with the same origin of medicine and food have different raw and cooked effects. For example, raw coix seed is clear of dampness and heat, and cooked coix seed is good for spleen and stomach; Some ingredients are rich in water-soluble ingredients, which are beneficial to absorption and digestion after cooking; Some ingredients need to be fully heated before they can be eaten, such as soybeans. If it is not handled properly, it will be ground into powder and washed before cooking, which may cause adverse reactions such as bloating and nausea.
Braised pork of the same dish, different restaurants make different flavors, why, and the proportion of formula.
Therefore, everyone should take supplements instead of eating them blindly, which is counterproductive.
