Are there any substances that are healthy for your health?
The vitamins market is booming. About a third of the population uses vitamins and nutritional supplements.
For decades scientists struggling on what is behind the alleged capsules ensuring good health. In recent years dietary supplements are increasingly criticized. Is lying on all these vitamins will come to light ? Researchers at the University of Copenhagen have succeeded in early 2007 to prove in their work that these vitamins can be harmful to health . For example , vitamin C , vitamins classic , does not increase the duration of life is what scientists at the University of Copenhagen have succeeded in demonstrating . The test takers who took regular basis vitamin A, L and beta-carotene in capsules even died prematurely . While this study was controversial because researchers conducted their work both on healthy people as people suffering from a disease . However, other research from the USA also addressed the subject.
The study by Harvard University of testing the effects of vitamins E and C on the body for eight years has proved that those tested did not live longer. Instead we even found that the administration of vitamin E resulted in a greater number of cerebral hemorrhages . Hope to guard against prostate cancer with vitamin was finally destroyed when the American Institute of Cancer abruptly interrupted his research after seeing an increase in diseases in men tested. Therefore vitamin preparations are not miracle and do not have magical healing powers .
However, is that athletes can take advantage of these preparations and increase the impact of training? Apparently there too , all hopes are lost. Researchers from the University of Valencia found that the daily intake of vitamin C is harmful to the health of athletes and slows particular performance. The active substance is bad for endurance. Indeed vitamin neutralizes free radicals in the body, so it no longer fits in the physical effort.
Therefore athletes should not rely on nutritional supplements but rather consider their own food. Because it is well known that a healthy and balanced diet is the best way to stay in shape . Nutritional supplements are generally reserved for the sick , the elderly , pregnant women and breastfeeding women. If one is healthy substances in fruits and vegetables , meat and fish enough to the body.
However, persons who wish to improve low levels of vitamins should consider the benefits of vitamin D. For many years, remained indifferent to the benefits of vitamin D , but today we know that it is a very important agent in the prevention of diseases. Vitamin D protects organs . Athletes can also draw many benefits. The substance is used to regulate the calcium in the body and plays an important role in the mineralization of the bone and the muscles . And since vitamin D is synthesized primarily in the skin under the influence of sunlight , it is best to take the air as much as possible instead of swallowing capsules.
