In order to keep delicious, people use a special technology to air-dry grapes, which can not only ensure that nutrients are not lost, but also have a special flavor.
In the era of health care, various folk remedies emerge one after another, such as soaking feet before going to bed and health tea. Some people even found the health value of grapes, and thought that chewing a few raisins before going to bed was of great benefit to conditioning the body. What is the truth? Let me show you:
1, Jianwei Xiaoshi
Raisins are rich in various dietary fibers and polyphenols, which can promote gastrointestinal peristalsis and relieve constipation. Some people have insufficient gastrointestinal function, decreased metabolic capacity, and can't consume food in time, resulting in a large amount of residues accumulating in the gastrointestinal tract, causing symptoms such as indigestion, abdominal distension, stomach pain and loss of appetite.
You know, the working hours of gastrointestinal digestion are concentrated from 9 pm to the early morning of the next day. If you chew a few raisins before going to bed, it can provide power for its metabolism and digestion, stimulate gastric acid secretion and strengthen digestion ability.
2. Anti-aging
"It is human nature to be born, sick and dead", but some women who love beauty "don't believe in life". They look for various nourishing tricks and spend a lot of money on skin care products in an attempt to delay the aging trend, but with little effect. Try chewing a few raisins. Raisins are rich in anthocyanins and are natural "antioxidants".
Step 3 prevent anemia
Female friends enter menopause after the age of 45, menopause, uterine and ovarian recession, insufficient secretion of estrogen and progesterone, and decreased iron synthesis ability will induce iron deficiency anemia. It was found that the iron index of raisins was extremely high. If eaten in moderation, raisins can supplement iron, promote cardiac hematopoiesis and prevent anemia.
4, oral cleaning
Some people think that raisins taste sweet, and eating them before going to bed is easy to cause tooth decay and dental caries, which increases the chance of oral diseases. In fact, the chief culprit of tooth decay is sucrose, and raisins are rich in fructose and glucose, which have no corrosive effect on enamel and can even inhibit oral anaerobic bacteria and play a cleaning role.
5. Prevention of cardiovascular diseases
Myocardial infarction, coronary heart disease and angina pectoris have become "health killers" for middle-aged and elderly people. Scientific research has proved that polyphenols in raisins can soften blood vessels, reduce blood lipids, prevent arteriosclerosis and prevent thrombosis; In addition, its vitamin E content is not low, which can not only help reduce the concentration of low-density lipoprotein in the body, but also resist oxidative free radicals and achieve the effect of delaying aging.
1, pay attention to cleaning
Food health and safety can not be ignored. Most fruits will be sprayed with pesticides many times during their growth and development to prevent pests. In the process of making dried fruits, bacteria, dust and so on will be attached. Therefore, please pay attention to clean the raisins in time, drain the water, and then eat them to avoid "illness from the mouth."
2. Don't eat moldy raisins.
Some middle-aged and elderly people will carve "frugality" into their genes, and for some raisins that have no obvious mildew, they will still choose to eat them after cleaning. Special reminder: the content of Aspergillus flavus in moldy food is extremely high, which is a carcinogen. Daily cleaning can't be removed. If you don't eat, you are responsible for your health.
