For thousands of years, white rice has not been the staple food of China people. In ancient times, people in northern China lived on small rice, while people in southern China ate brown rice. The history of polished rice is only 100 years, until 30 years ago? 92 meters? (Note that it refers to the grinding fineness of rice, and 92 meters means 100 kilograms of rice grinds out 92 kilograms of rice), not the current polished rice (? 75? Meters or even lower). After grinding to remove the vitamins and minerals, the nutritional value of white rice is low.
So what shall we eat instead of white rice? The answer is brown rice. Protein, germ, chaff and aleurone layer, which are rich in B vitamins and minerals, are preserved in brown rice, which has high nutritional value. The chaff layer of brown rice and aleurone layer are not easy to cook, digest and eat. For people with poor digestion and people who want nutrition, you can choose germ rice. Germ rice removes most of the bran layer and aleurone layer, and retains the germ part with concentrated nutrition. Rice is soft and easy to digest. However, because of its rich nutrition, microorganisms like germ rice very much, so the shelf life of germ rice can only be kept for about 3 months under vacuum packaging, and it is only about 15 days after opening the bag. So it is not common in the market.
This one won't work, and neither will that one. Now you finally know why rice can only be our staple food in the end, right? For modern people, eating a lot of white rice every day is really not a healthy choice. On the one hand, the high glycemic index is likely to lead to insulin resistance, which will lead to blood sugar problems. On the other hand, due to the improvement of processing precision, the proportion of protein and micronutrients in white rice is further reduced, which is why the gym coach asks you to reduce the amount of rice as much as possible when guiding you to lose weight.
After reading this, the whole person is at a loss. Do you doubt your life? Is white rice really useless? Although the nutritional value of rice is low, its carbohydrate content accounts for a high proportion, and it is the best food to provide energy. A single food cannot require balanced nutrition, and nutritious eggs also have no vitamin C and dietary fiber. If there is such food, we will eat it! In recent years, the Nutrition Society of China and the American Dietary Guidelines strongly recommend the whole grain diet. Dietary Guide for China Residents recommends the concept of whole-grain diet, adding 1/4~ 1/3 whole-grain food or miscellaneous beans to grains (white rice/flour food), such as making miscellaneous grains rice. Eat less rice noodles, bean jelly, bean jelly, they are more than white rice? Rubbish? . This kind of food is made of starch in rice, so it only contains starch, not protein, so it has almost no nutritional value.
