Antioxidants in fruits

Eating fruits rich in antioxidants, such as blueberries, is good for your health, as well as preventing diseases A study conducted by US scientists has confirmed that just one cup of blueberry a day can provide antioxidants for disease prevention Of course, nutritionists usually recommend following a balanced diet and taking a variety of nutrients from different food sources Antioxidants are important compounds against diseases Scientists believe that they help prevent and repair oxidative stress, a natural process of normal cell function In this process, a small number of cells are damaged during oxidation and transformed into free radicals, and then start a chain of reactions that damage more cells and cause disease It has been proved that the destructive activities of free radicals are closely related to cancer, heart disease, Alzheimer's disease and Parkinson's disease A foreign study evaluated the antioxidant levels of more than 100 foods, including fruits, vegetables, grains, pasta, nuts and spices The results showed that blueberries, blueberries and blackberries had the highest antioxidant content in all fruits Then there are apples and dried fruits In addition, peaches, mangoes and melons, although not as many as blueberries, also contain a lot of antioxidants and other nutrients Although some fruits and vegetables contain a lot of antioxidants, they cannot be fully absorbed by the human body This concept is also known as bioavailability, involving intestinal absorption or metabolism This means that specific absorption is influenced by the structure of different antioxidants in food, i.e whether they adhere to fibers or bind to sugar molecules In addition, some foods are more healthful when properly cooked Other studies have confirmed that steaming blueberries can enhance the antioxidant level and make the body absorb more antioxidants Because of the different bioavailability of food, it is very important to ensure the diversity of diet Purple blue red orange fruits contain the most antioxidants In particular, blueberry has the highest antioxidant content, including vitamin A and C, and flavonoids such as quercetin and anthocyanin In addition, raspberries, strawberries, black plums, sweet cherries and red grapes also contain a lot of vitamin A and C, as well as catechins, epicatechins, quercetin and anthocyanins A large number of studies have confirmed that red wine, grape juice, grape seed and grape skin extract contain a lot of antioxidants Red wine, for example, is rich in flavonoids such as anthocyanins and catechins It has been proved that eating grape food can delay the process of artery occlusion Scientists were interested in the French diet and found that their low incidence rate of heart disease was directly related to their habit of drinking red wine.
