Grapes are deeply loved by the public for their unique sweet and sour taste. They can be eaten fresh or made into a variety of processed products. Let's take a look at the nutritional benefits of grapes.
Grapes can be eaten fresh or processed into various products, such as wine, grape juice, raisins, etc. Eating more grapes and drinking wine in moderation is very beneficial to human health. For postpartum women in particular, drinking some wine in moderation can not only help blood circulation but also increase the body's hemoglobin.
According to measurements, grapes contain a variety of vitamins and minerals such as citric acid, salicylic acid, carotene, riboflavin, calcium, phosphorus, iron, and more. Grape juice, seeds, and skins are rich in powerful antioxidants—resveratrol and flavonoids. These two substances have the effects of dissolving clots and preventing blood clotting, similar to aspirin, and can defend against ischemic stroke, such as cerebral infarction and cerebral thrombosis.
In traditional Chinese medicine, grapes are considered to have a neutral nature and a sweet flavor, and they enter the lung, spleen, and meridians. They can nourish qi and blood, strengthen muscles and bones, unblock meridians, promote urination and reduce swelling, and benefit the kidneys and liver. Ancient Chinese books have long recorded the medicinal and health benefits of grapes: "Dian Nan Ben Cao" says: "Greatly supplements qi and blood, relaxes muscles and activates collaterals." "Dian Nan Ben Cao Tu Shuo" says: "For treating smallpox poison and fetal qi rushing upward, drinking it as a decoction will bring it down." "Ben Zao Zai Xin" says it "warms the stomach and strengthens the spleen." "Sui Xi Ju Yin Shi Pu" believes it "supplements qi, nourishes kidney fluid, benefits liver yin, strengthens muscles and bones, quenches thirst, and secures the fetus." "Lu Chuan Ben Cao" records: "Nourishing and strengthening, replenishing blood, strengthening the heart and promoting urination, treating back pain, stomach pain, mental fatigue, blood deficiency, and palpitations." "Shen Nong Ben Cao Jing" records: "It increases qi, doubles strength, strengthens will, makes one plump and healthy, endures hunger and cold wind, and long-term consumption makes the body light, prevents aging, and prolongs life." However, traditional Chinese medicine believes that grapes are cold in nature. Those with disharmony of the spleen and stomach or those with deficiency-cold and diarrhea should avoid eating them.
When cleaning fresh grapes that you have just bought, do not remove the stems, because removing them will expose the flesh to the air, which will not only attract small insects but also speed up oxidation. Note that washed grapes must be refrigerated. Grapes that cannot be finished at ordinary times are also best to be sealed with plastic wrap as a whole bunch and placed in the refrigerator for refrigeration.
Scientific research has found that grape skins contain a chemical substance called resveratrol, which can prevent normal cells from becoming cancerous. Grape skins also contain a component that can lower blood pressure, which has a good effect on lowering blood pressure and resisting atherosclerosis. Therefore, it is best not to spit out grape skins when eating grapes.
