Background: At the Beijing Olympics, the Jamaican athletes in the sprint of the amazing advantages of the project so that people have to speculate on their full physical sources. Media reports, talking about his son is able to run as fast as the reason, "Trapeze," Boldt's father, Wellesley Bolt would like to thank the most is the homeland of the Chinese yam. Boldt trelawney at home, every year tens of thousands of catties yam exports from here. "He is grown up eating Chinese yam, Chinese yam has created him the power of today. "Wellesley recalls.
Although many people probably laughed at this statement, even Bolt himself said that he does not like to eat the yam. However, there are many Jamaicans believe that is their root vegetables and herbs forged the success of trapeze. So, whether yam has high health values? It is there to help improve physical fitness? Let us take a look at some of yam on the results of the study.
Studies have shown that yam starch is much more than just a food, it is rich in a variety of nutrient composition, protein content of dried rice are twice content of B vitamins are several times more than rice, minerals rich in potassium. More important is that the yam is rich in a variety of physiologically active components, including yam polysaccharide, mucus protein, saponins, allantoin, such as dehydroepiandrosterone.
many study found that Chinese yam extract has good anti-aging effects, can improve animal immune cell proliferation capacity, delay the aging thymus, determination showed that the yam polysaccharide can eliminate a variety of free radicals and enhance antioxidant enzyme systems in vivo activity, reducing the content of oxidation products. Yam mucus protein may enhance immune function in animals, to improve cardiovascular function, and yam contained dehydroepiandrosterone also strengthen the immune function, improve memory, sedation sedative-hypnotic, slow skeletal muscle aging, the prevention of atherosclerosis and other delay role in aging.
Taiwan study found that some species of yam can reduce the growth of human breast cancer cell activity. Studies have found that yam polysaccharide on melanoma cells and lung cancer cells have inhibitory effects, thus speculate yam consumption in favor of cancer prevention.
people have a lot of people think diabetes should not eat the potato starch-containing food, in fact this is a wrong understanding. Compared to rice flour and food, including a variety of yam tuber crops, including food products are beneficial to control blood sugar, but also to improve the physique.
Western researchers have specifically studied the Giamaica bitter yam extract on the role of mice and found that it can effectively lower blood glucose levels and cholesterol levels. China and Japan, the study also proved that yam can reduce exogenous glucose or epinephrine-induced mice elevated blood glucose and lipids. Our country has the human study found that people with diabetes yam can help to reduce insulin resistance and improve peripheral tissue utilization of glucose; food Shan add powder and flour can improve diabetes philoxeroides people of fatigue, hunger, many urinary symptoms such as blood cholesterol also have to improve . However, if instead of eating yam extract concentrated, and its hypoglycemic effect and should not comparable with hypoglycemic agents, but also not a perfect substitute for insulin, can be used as an adjunct to dietary treatment measures.
our country since ancient times have always been a very high regard for yam as a health Jiapin. The ancients believed that "good health were raised, the poor health were raised apart. "In other words, the people know how to keep in good health, let the visceral function of strong, physical plenty, but do not seem fat, and had no fat. Health of the people who are not good at, the surface shape muscular, in fact, the function of weak, poor physical fitness. The yam tuber crops such as food, is recommended by health food home. It is not only nutritious, there is the promotion of digestion and absorption, and strengthen blood vessels, the role of the prevention of chronic diseases, as well as conducive to weight control.
so healthy a food, of course, worthy of regular consumption. However, since the life of the rich, the inhabitants of our country potato intake significantly decreased, yam, taro, sweet potato, have also been the majority of families are left out in the cold table. Palatability of course, rice flour, the price is lower nutritional value. From small to large have as a food, this will definitely affect the national constitution.
In recent years, even if the consumption of potato, but also, as are many dishes or snacks, rather than as a staple food. In fact, the potato to a partial substitute for refined white rice noodle, eat work, is to play a role in the best way to health. For chronic diseases for people, but also should pay attention to reduce the fine rice noodle with tubers, pulses and coarse grains to replace. Fortunately, there is currently on sale everywhere Mountain powder, add it to flour, rice and other staple food which can easily fit for human consumption, very convenient.
healthy nutritional balance in life, coupled with some potato, perhaps feeling more energetic and healthy return to their body, though should not run swiftly, staggered at least light, physical date, and how such a happy life.
