Both are fine. It depends on which color or taste you personally like. Personally, I prefer red to sweet. Grapes are rich in nutrition. According to scientific analysis, they contain more than a dozen indispensable amino acids such as glutamic acid, arginine and tryptophan. Therefore, eating some grapes regularly is of great benefit to the normal activities of the nervous system and cardiovascular system and can prolong life. The ancients also said: "Eating grapes for a long time is not old." Grape has high nutritional value, and grape juice is praised as "plant milk" by scientists. The sugar content of grapes is about 10%-25%, and the highest is about 30. Most of the sugar contained in grapes is glucose that can be directly absorbed by human body, so grapes become an ideal fruit with weak digestive ability. Grapes contain more tartaric acid, which is more helpful for digestion. Eating more grapes properly can strengthen the spleen and stomach, which is of great benefit to the body. Medical research has proved that grape juice is the best food for patients with inflammation, which can reduce the contents of protein and sodium chloride in blood. Grape juice plays an auxiliary role in the rehabilitation of weak patients, arteriosclerosis patients and nephritis patients, and the incidence of cancer is also significantly reduced in places where grapes are planted and eaten more. Grape is the fruit with the most complex iron element, and it is a nutritious food for anemia patients. Eating grapes regularly is beneficial to neurasthenia and fatigue. After the grapes are dried in the sun, the contents of sugar and iron are relatively increased, which is a good tonic for children, women and people with weakness and anemia.
