First of all, oxalic acid widely exists in various plants, especially vegetables, sweet potatoes, taro and so on. Among them, oxalic acid content such as spinach, amaranth, celery and so on. Many times that of tea. We drink about 3 grams of tea, while eating vegetables usually takes several hundred grams. If we can't drink tea at the same time, can we eat vegetables at the same time?
Secondly, Mr. Lin Zhi, a herdsman in pastoral areas and a tea farmer in tea areas, said that many centenarians interviewed had the habit of drinking tea while eating. For example, Mrs. Liu, who is 65,438+065,438+06 years old and can walk on the Great Wall, and Mrs. Amat, who is 65,438+065,438+00 years old in yutian county, Xinjiang, are used to eating at the same time. These phenomena show that the content of some substances has not reached the point of being harmful to health. Just pay attention to the correct drinking method and don't worry too much.
The second reason for those who think that drinking tea while eating is unhealthy is that tea polyphenols in tea will combine with nutrients such as protein and fat, which will affect digestion and absorption. Indeed, a large number of experiments on mice also show that this statement is correct. In the experiment, two groups of mice were fed the same high-fat high-protein high-calorie feed, one group was mixed with tea powder, and the control group was not mixed with tea powder. After feeding for a period of time, mice without tea powder were round and obese, and generally suffered from fatty liver, while mice with tea powder were lighter in weight and normal in liver. The results showed that some of the fat and protein eaten by this group of mice were combined with tea polyphenols to feed tea without being absorbed, but were excreted with feces.
If food is insufficient, this phenomenon will naturally lead to malnutrition, which will affect health by reducing the absorption rate of protein and fat. However, it is of great significance to the successful people who are currently over-nourished, especially those who eat too much fat, protein and sugar. Drinking tea while eating can not only make a full meal, but also effectively reduce the digestion and absorption rate of excessive nutrients, thus avoiding weight gain and preventing fatty liver and "three highs". Why not?
Therefore, the theory of health preservation must keep pace with the times. At present, most people are overnourished (please note that there is an excess of fat, sugar and protein, but the overall nutrition is unbalanced). It is a bit outdated to talk about "drinking tea while eating" with the theory of malnutrition era.
In addition, the clever cooperation between tea and meals is not only beneficial to health, but also can improve the taste and quality of catering. For example, taking two sips of alpine oolong tea after eating seafood can remove the fishy smell and activate the taste buds on the tongue, and the next dish will be more delicious.
