Research recently performed has discovered that consumption of omega-3 PUFAs (polyunsaturated fatty acids) found in fish and other seafood could lower the chance of women getting colorectal precancerous polyps for one thing. This could also heighten results for women with strength training. In addition, after corneal surgery, the health of the eyes can be better by consuming the omega-2 PUFAs. The information was published in April 2012 editions of the PUFA Newsletter for health professionals and the Fats of Life e-newsletter for consumers.
Omega-3 For Colorectal Polyps
Research took place with women 50 years of age and older that had been tested for colorectal cancer. The ones who had the largest consumption of omega-3 PUFAs were 77 percent less likely to contract colorectal polyps when compared to the ones with a low intake of the omega-3 PUFAs. These polyps can turn into colorectal cancer, which ranks 3 in cancers suffered in the United States.
A different study took place with older women who were given fish oil supplements for three months, while they also participated in strength training. Another group only did the strength training. When the results were compared between the two groups, the one that had the women on the fish oil supplements had the largest gain in muscle strength.
According to Joyce Nettleton, D.Sc., the editor of the newsletters mentioned above, more observations are needed to verify these findings. She goes on to state that it does appear there are additional benefits for women to consume omega-3. Joyce also points out that more needs to be done to prevent colorectal cancer.
In addition, results of two studies on the effects that omega-3 PUFAs from seafood have on the eyes were included in the same newsletters. One was performed with animals and stated that the corneal nerves with completely regenerated using topical applications of DHA, which is a long-chain omega-3 after corneal surgery had been performed. The other one was showed that additional consumption of the long-chain omega-3s resulted in a slowing of vision loss in adults that suffered from retinitis pigmentosa, which is a genetic form of retinal disease. The ones that consumed a minimum of 200 mg of the long-chain omega-3s each day along with high dose of vitamin A had noticeable slower vision loss that those that consumed less of the omega-3 and the same dosage of the vitamin A.
These results would seem to point to the importance of omega-3 PUFAs for eye health all through life. With the retinitis pigmentosa, the results seem to reveal that many patients could retain their visions for a major part of their lives by consuming a high dose of vitamin A each day along with at minimum 200 mg of omega-3s. This is a huge find.
