Italian scientists announced a discovery: eating grapes helps sleep. According to the report, the researchers tested a total of eight grape juices and found that they may contain melatonin, a sleep-helping hormone. Melatonin is a substance secreted by the pineal gland in the brain that helps regulate sleep cycles and treat insomnia.
In fact, in addition to helping sleep, grapes have many benefits. Grapes are rich in nutrients. According to the test, 100 grams of fresh grapes are eaten daily to meet the 4% calcium requirement, 1.6% magnesium content, 0.12% phosphorus content, 16.4% iron content, and copper content. 2.7% and 16.6% of manganese. Grape can replenishing qi and blood, strengthening bones and muscles, passing through meridians, swelling and urinating, and can play a role in tonifying kidney, strengthening waist, nourishing and benefiting blood, reducing blood pressure and appetizing, especially in the prevention and treatment of neurasthenia, abdominal pain and abdominal distention. , cardiovascular disease and other aspects have a more significant effect.
Modern medicine found that grape skin and grape seed contain an antioxidant substance resveratrol, which has preventive and therapeutic effects on skin cancer and cardiovascular and cerebrovascular diseases. In addition, Natural pigments in grape skins have good effects on lowering blood sugar and cancer, while dark (red, red) grapes have higher natural pigment content than light-colored (Green, white) grape skins. There will be a lot of loss of function. Therefore, there is a scientific reason for “grape grapes do not spit grape skinâ€.
In addition, grapes and their products also have antiviral activity components. Studies have shown that fresh grapes and grape juice have stronger antiviral power than wine, and wines have strong red wine abilities. Red wine contains flavonoids, especially quercetin, which can reduce the viscosity of platelets. Liquor and beer have no such benefits. Therefore, moderate consumption of red wine can protect the heart and reduce the risk of cardiovascular diseases. .
