Scientists have different views if they think vitamin D and fish oil supplements are fighting cancer and heart disease.
An independent study, sponsored by the American Association of Cardiology, says supplements containing omega-3 or vitamin D do not help prevent cancer or cardiovascular disease.
The authors of the study, published in the New England Journal of Medicine, claim that "those selling vitamin D are selling it well." But Vitamin D "did not show any good," says Dr. James Stein, a cardiologist at the University of Wisconsin-Madison, Wisconsin.
In this study, over 26,000 healthy adults consumed vitamin D supplements or fish supplements for five years. The researchers found that subjects had less risk of developing cancer or cardiovascular disease.
But the situation is not so much. Those taking vitamin D supplements for at least two years have shown a 25% reduction in the chance of developing cancer.
In addition, too much vitamin D in the body can increase the risk of kidney stones, and some people can cause problems with the face or blood vessels.
It is said that fish oil prevents infarction and blood vessel invasion and stimulates brain activity. So it is desirable to consume it naturally.
Even if the discovery of scientists could be an alarm signal, they remind us of the golden rule – theft of everything.
