Fish is considered a very useful product, and its use is mainly due to the presence of omega-3 unsaturated fatty acids. This term is generally understood to be substances which are part of cell membranes and blood vessels. Unfortunately, the human body cannot produce them in sufficient quantities, so many people are trying to make up the balance using certain products and biological additives. And all because it is believed that these acids can reduce the risk of developing cardiovascular diseases and even cancer. However, recently the staff of the University of East Anglia found that all praise substances have little effect on predisposition to heart disease and cancer, and in some cases can even cause some harm.
The results of the study were published in the scientific journal British Journal of Cancer. Scientific work lay in the fact that scientists have collected together the results of studies on the effects of omega-3 fatty acids on the human body and appreciate how much they reduce the risk of developing deadly diseases. Of the study covered the data of at least 100 thousand people, which for one year used supplements with omega-3 acids. Among them were people with a predisposition to cancer and heart disease.
What are the benefits of omega-3 fatty acids?
After studying caught up in their disposal the data, the researchers came to the conclusion that the benefits of omega-3 fatty acids, which in large quantities found in fish, are overrated. It turned out that consumed their people, very rarely escaped from cardiovascular diseases. For clarity, the scientists gave an example: if 1000 people ate omega-3 acid for four years, from heart disease would have died for just three people less. And at the risk of developing cancer , these substances, as it turned out, almost no influence. Moreover, the scientists found that the supplements might slightly increase the likelihood of prostate cancer.
But afraid of nothing, because the harm from omega-3 fatty acids minimum, just like their benefits. However, it remains unknown how truthful the information that the test substance have a positive effect on bone health, skin health, brain function and the human immune system. Most likely, this or another group of scientists will find the answer to this question. Maybe work on this has already begun.
Why you should eat fish?
Yes, the use of omega-3 fatty acids is now under question. However, according to study author Lee Hooper, fatty fish is still a very nutritious product, which has many other nutrients. In particular, it is rich in protein and such trace elements as iodine, vitamin D, calcium and selenium. It is known that iodine improves metabolism and strengthens the immune system, and vitamin D improves the assimilation of calcium, which is good for bones and the nervous system. It is also known that calcium plays an important role in the reduction of muscles of the human body. The mineral selenium, in turn, slows down the inflammatory processes and improves the functioning of the thyroid gland.
