Chapter 59 vegetarian variety

Dear Xiaowen: There are four poems in English: Its a very odd thing—— As odd as can be—— That whatever Miss T eats Turns into Miss T. (Walter de la Mare, "Miss T." 1913) (That's a very strange thing, you can blame it all you want, no matter what Miss T eats, she turns into Miss T.) why?Because Miss T has a set of nutrition in her stomach, which is called "nutrition" in Chinese.The most important "nutrients" are: 1. Proteins—Proteins are the materials that increase and repair body tissues, just like the bricks of a house.Protein cannot exist in the body, so it must be eaten every day.

If you lack protein, you will get "Beat Ten Oaker" disease. kwashiorkor—an often fatal condition of infants and young children caused by a protein deficiency in the diet. It occurs among poorer peoples of the world and cause stunted physical and mental growth, loss of hair pigment, swelling of tissues, etc. African small Black people are very poor, and they only eat enough calories and not enough protein, so they often suffer from this disease.Not only humans, but also animals can't do without protein. Mice can't grow up without protein, and they walk lazily. Too much protein in food is useless, it has to have a "biological value" (Biological Value), which is the amount of "amino acids" (amino acids) contained, although peanuts (peanuts) have more protein than eggs (eggs) , but the physiological value is less, so the egg has the most protein, because the protein has the most physiological value.

Animal protein is more physiologically valuable than vegetable protein, so those who eat less meat or who are vegetarians will be smaller. "Vegetarianism" (vegetarianism) is very humane, but the lack of protein is a big problem. Many celebrities are vegetarians, such people are called vegetarians, the great French philosopher and thinker Rousseau in the 18th century was a vegetarian, and the Russian writer Leo Tolstoy in the 19th and 20th centuries was a vegetarian , The British writer George Bernard Shaw from the nineteenth to the twentieth century was a vegetarian, and the Indian Gandhi (Gandhi) that Dad repeatedly mentioned to you was also a vegetarian.Vegetarians live longer. Shaw lived to ninety-four, Tolstoy lived to eighty-two, Gandhi lived to seventy-eight (stabbed), and Rousseau lived to sixty-six (legendary to be murdered). It can be seen that eating only protein Plant-based seems to be enough.

2. Carbohydrates - Carbohydrates give people energy. People need energy for walking, writing, fighting, flying eyes, and defecating. Carbohydrates are the electricity for electric lights and gasoline for cars. Carbohydrates are the most sugar, as follows With this table, you can clearly know the percentage of sugar in food: Sugar 100 Banana 22.0 Rice 90.0 Corn 19.2 Prune 73.3 Potato 18.4 Molasses (cane) 69.3 Grapefruit 14.4 Oatmeal 67.5 Apple 14.2 Lima beans65.9Orange11.6 White bread 53.1 Milk 4.9 whole-wheat bread 49.7 Celery 3.7 3. Fats—it also gives energy to people. If people can’t use it, the excess fat will be stored, so they become fat and become Mr. Five-by-Five, just like the sixth uncle, and the sixth uncle is fatter One point, just like the big fat man in the picture.

4. Vitamins, that is, vitamins (vitamins) - vitamins cannot be deficient, and if they are deficient, strange problems will arise. For example, two piglets will look different if one of them lacks vitamin B1.Vitamin D deficiency causes rickets. Five, minerals (minerals) - lack of calcium, teeth and bones will be affected.The human body also needs many other minerals. Six, water (water) - water accounts for 60% - 65% of the body weight.Some people say that women are made of water and men are made of mud, but in fact both men and women are made of water. There are two kinds of nutritional diseases, one is malnutrition, and the other is overweight due to eating too well.
