The jobs funded by the US government were quite curious for cardiologists and nutritionists.
Experts from several national health institutes for five years undertook a series of concurrent experiments to study the benefits of fish oil and vitamin D. Overall, 26,000 people 50 years of age or older participated in the new survey. None of them were ill at the time of the survey and had no history of treating heart disease or cancer, from which fish oil and vitamin D are supposed to protect themselves.
Four groups of participants took different drugs daily: the first group – 1 g of fish oil and 2000 IU of vitamin D, the second – 2000 IU of vitamin D and placebo, the third – 1 g of fish oil and placebo and the room – only placebo. At the conclusion of the experiments, scientists were unable to determine which group was taking which drug. Thus, these results, published in the New England Journal of Medicine, have completely refuted the benefits of these supplements in preventing cancer or heart disease.
Although not everything turned out to be so one-sided. Omega-3s contained in fish oil reduce the risk of a heart attack, but those who do not include fish in the daily menu receive the greatest benefit from this supplement. At the same time, vitamin complexes with omega-3s and vitamin D remain a harmless additive to a balanced diet, nutritionists say.
