Grapes are a fruit that has many beneficial properties for our health, let's discover them together
Delicious fruit with a typical autumn flavor, grapes cannot be missing on our tables, starting from the last days of August. Few calories, many vitamins and an excellent presence of minerals make this food a real panacea, but what are its properties?
As the experts of the Humanitas group reveal, the nutritional properties of grapes are very interesting: in a 100 gram portion there are just 61 calories, but it is its micronutrient content that makes it a very precious fruit. As for its vitamin intake, it includes a good amount of B vitamins (in particular niacin, thiamin and riboflavin), essential for the functioning of the metabolism and the nervous system.
Grapes are also an excellent source of antioxidants, and in particular of vitamin C, beta-carotene and quercetin: these substances act against free radicals, the main culprits of oxidative stress. This condition is associated with numerous chronic diseases, among which we can include diabetes, some forms of cancer and various diseases of the heart. The greatest concentration of antioxidants is found in the peel and seeds of this fruit.
Red grapes, particularly rich in flavonoids (anthocyanins, from which it takes its color) and phenols (resveratrol), protects against problems with the cardiovascular system, decreases blood sugar levels and, as shown by a recent study published in Molecular Nutrition and Food Research, it performs an anticancer activity and reduces the proliferation of cancerous cells.
Reservatrol, as well as other substances contained in white grapes, is a powerful anti-inflammatory and for this reason it prevents and fights some chronic ailments, including autoimmune diseases, intestinal problems and diabetes. It also helps the body to eradicate viruses and bacteria, especially when it comes to food poisoning.
For the cardiovascular system, grapes are a real panacea: their high potassium content decreases the risk of suffering from high blood pressure and heart attack, while antioxidants protect the heart by reducing the absorption of LDL cholesterol. This last characteristic, in particular, would seem to be linked to the presence of reservatrol, and therefore it is a benefit brought mainly by red grapes.
Finally, this fruit has several other benefits for our body. Antioxidants reduce the risk of incurring macular degeneration with advancing age, as well as protecting against glaucoma and cataracts. While a study published in Current Osteoporosis Reports correlates the presence of micronutrients such as calcium, magnesium, phosphorus, manganese and vitamin K with maintaining bone health and reducing the risk of developing osteoporosis.
