"What did you have for dinner yesterday? Some people as long as 1 second to answer immediately, there are individuals but after 5 minutes still can not think of, beware of may be a sign of brain aging, once the lack of nutrition or stress, more will aggravate the load on the brain, so that the phenomenon of inattention, forgetfulness is more serious. Nutritionists say that in the emerging concept of phytochemicals, flavonoids are better at preventing and delaying brain degeneration.
Flavonoids are the most diverse family of phytochemicals known, and are commonly found in fruits and vegetables such as tomatoes and grapes, as well as in nuts, beans, and green tea.Phytochemicals are diverse, and flavonoids are the most effective way to prevent brain degeneration
The dietitian at Daqian General Hospital, Mr. Jiang Shifeng, said the phytochemicals, which are referred to as phytochemicals, are metabolized by plants and are the secondary metabolites of plants, and they have become a hot topic of nutritional science in recent years. The common phytochemicals known to date can be divided into flavonoids, carotenoids, phenolic acids, organosulfides, phytoestrogens, and other difficult to categorize chlorophyll, curcumin, limonene, citrulline, lemon bittersweet, saponins, and bittersweet glycosides.
Among them, flavonoids belong to the polyphenolic compounds, is the most varied family of phytochemicals, commonly including proanthocyanidins, anthocyanidins, catechins, gerberellins, apigenin, and citrulline, etc., the study found that humans have antioxidant, cancer cell inhibition, as well as anti-allergy and anti-inflammatory functions, and also is the dietitians believe that it helps to most "prevent or slow down the deterioration of the brain," the phytochemicals. Flavonoids are found in fruits and vegetables such as tomatoes and grapes, nuts, beans, and green tea.
For brain memory, phytochemicals can only achieve the effect of prevention, can not directly improve and enhance? Jiang Shifeng nutritionist said, phytochemicals in addition to food intake, digestion and absorption, the last pass through the blood-brain barrier, the role of the brain is still a question mark, because in addition to oxygen, carbon dioxide and glucose and other brain cell necessities and metabolic waste, most of the ions, drugs and proteins can not diffuse through the blood-brain barrier.
