Vitamin C supplementation is not more
As an essential nutrient for the human body, men's daily intake of vitamin c should be no less than 90 milligrams and women no less than 75 milligrams. On this basis, adequate supplementation of vitamin C can also prevent arthritis. However, is it better to make up as much as possible? Scientists in North Carolina, USA, found that if you take too much vitamin C over a long period of time, it will not only be useless, but it may even worsen arthritis. In addition, the excessive intake of vitamin C will also have side effects such as diarrhea, ion imbalance, kidney stones. Therefore, vitamin C supplementation is not "better and better."
Sports can prevent arteriosclerosis
At present, it is believed that the main direct cause of heart disease and stroke, arteriosclerosis, is the cumulative result of prolonged arterial intimal lesions. This long-term injury process may begin when the patient is young. Australian scientists found that obese young people are more likely to have arteriosclerosis than their normal weight counterparts, according to the obese young arterial intimal relaxation response is poor. Fortunately, this condition can be corrected by physical exercise. After three weeks of regular exercise, even if the weight of the obese youth does not change, the functional test of the arterial intima will return to normal levels. However, the exercise must be adhered to, otherwise the function index of the arterial intima will return to the pre-exercise state.
Drinking too much alcohol can protect the liver
American scientists based on the analysis of the results of the health and nutrition survey report found that drinking coffee and beverages containing caffeine can reduce the risk of alcohol damage to the liver. The subjects of the investigation and study are mainly those who drink too much alcohol. Under normal circumstances, long-term excessive drinking can damage the liver, causing fatty liver and cirrhosis. If you drink two cups of coffee or other beverages containing caffeine per day, the risk of alcohol injury to the liver can drop to 44% and 69%, respectively. However, the principle of the role of caffeine for liver protection needs further study and confirmation.
Orange peel lowers cholesterol
There was a period when everyone was drinking orange peeled tea before the popular black tea. If someone can persist until today, he may at least not worry about high cholesterol in the blood. Recently, Canadian scientists discovered that the chemical ingredients contained in the orange peel can reduce blood cholesterol levels. For the first time, this study found that in addition to known health effects, this type of chemical composition can also lower the concentration of blood-induced LDL cholesterol-induced atherosclerosis. Maybe think twice before throwing away the orange peel next time.
Drink two pieces of tea each day, or you can drink it alone. Orange peel is a "secret weapon" for cooking enthusiasts. Adding some of the porridge and stews will add a lot of fragrance. Not only don't feel bad about it, or blindly cure it.
Marine fish is resistant to neonatal asthma
If the mother has asthma, she may be inadvertently inherited by the child. If you pay attention, you may be able to prevent this from happening. According to a survey by American scientists, if asthmatic mothers often eat oily marine fish such as salmon or salmon during pregnancy, the risk of asthma after birth can be reduced by 70%. Because marine fish contains a large amount of omega fatty acids, it can inhibit the body's inflammatory response, thereby reducing the incidence of asthma. Need to be particularly reminded that eating fish should pay attention to the content of mercury in marine fish.
Blood pressure in patients with blood pressure at home is best
British doctors have recently found that patients who regularly monitor their blood pressure at home have the best antihypertensive effect. The study has investigated 2 714 hypertensive patients. About half of them measure their own blood pressure at home and the other half regularly go to hospitals or clinics to measure blood pressure. The results show that patients who have blood pressure at home often have systolic or diastolic blood pressure. Lower than the other group. According to the analysis, the reason why the blood pressure of the doctors asked patients to have high blood pressure was not due to the "white coat effect" of "seeing doctors." The real reason may be that patients who regularly monitor their blood pressure can find out whether the blood pressure is high or not, and how far they are from the blood pressure goal. At the same time, various blood pressure reduction measures are carefully implemented to pay attention to the results of health care in life.
More language slows aging
One of the manifestations of aging is the dullness of thinking. This natural phenomenon cannot be changed at present. However, Canadian psychologists have recently discovered that people who speak two languages ​​are better at speaking about reducing or delaying mental decline. The testers used heart tests to test young people, bilinguals, and monolingual seniors in terms of differences in observational power and reaction power. The results showed that the elderly who grew up in both language environments were very close to young people in terms of mental performance. Bilingual seniors and monolingual seniors are more likely to show intelligence advantages. Scientists believe that using two languages ​​for human brain exercise has greatly mobilized the potential of the brain in analyzing, synthesizing, and storing information. This type of exercise delays the decline of the brain after it enters old age.
