Kidney Cancer Risk May Be Lowered Through Fatty Fish Consumption
|
Fatty fish, which is also referred to as oily fish or cold-water fish, is very rich in the omega 3 fatty acids, DHA and EPA. And these essential fatty acids are well-studied and known to have a whole array of different health benefits.
Among their beneficial and healthful properties are anti-cancer effects, as highlighted in the following article.
Fatty Fish may Reduce Kidney Cancer Risk
by Reuben Chow
More and more research is uncovering the beneficial qualities of fatty or oily fish as a healthy food. A recent study in Sweden has added to this databank of knowledge, having found that Swedish women who consumed such fish at least once every week had a markedly lower risk of developing kidney cancer, as compared to those who did not eat fish or who ate lean fish.
Details and Findings of Study
The said study, published in the Journal of the American Medical Association, had run for 15 years and looked at some 61,000 women in the country. The women were aged 40 to 76 and, among them, 150 developed cancer of the kidneys. Generally speaking, this disease is more likely to strike men than women.
The study found that people who ate fish which contained high levels of omega-3 fatty acids and vitamin D had a 74% lower likelihood of getting kidney cancer, as compared to people who did not eat fish at all. These important nutrients are found in significantly greater amounts in fatty or oily fish such as herring, mackerel and salmon. On the other hand, the study also discovered that leaner fish like cod and tuna did not bring about the same protective effect against kidney cancer.
Other Health Benefits of Fatty Fish
Other recent studies have surfaced the health benefits of fatty fish. For example, a Norwegian study which looked at the fish-eating habits of over 2,000 elderly persons and their cognitive performance had found that those who consumed fish scored much better on six different cognitive tests. This was after other factors which could affect the results, such as education levels, had been accounted for. It was also found that, the more fish and fish products eaten, the better the test scores. Significantly, it was revealed that fatty fish and non-processed lean fish offered better effects, as compared to other varieties of fish and fish products.
