Omega-3 New Information

We've known for years that omega-3 fatty acids are good for the heart. These healthy fats down-regulate inflammation, and may help reduce the risk and symptoms of disorders influenced by inflammation, including heart attack, stroke and several forms of cancer. Now researchers at the University of California, San Francisco, have found another action of omega-3s that may help explain why they offer benefits for the heart. The investigators found that the more omega-3 consumed by patients with coronary heart disease, the slower the structures called telomeres at the ends of chromosomes shrank. (Telomeres have been likened to the caps on the ends of shoelaces that prevent the laces from unraveling. In cells, telomeres prevent chromosomes from fusing with one another or rearranging - undesirable changes that could lead to serious diseases.) The more times a cell divides, the shorter telomeres become, a change that makes them a marker of biological age. The California investigators followed about 600 patients with coronary artery disease and measured their blood levels of omega-3s and telomere length at the beginning of the study and again five years later. They found that the higher the blood levels of omega-3s, the slower telomeres shortened, suggesting that the rate of biological aging - as mirrored by telomeres - decreased.



My take? This is a fascinating area of research and may give us new insight into how omega-3 fatty acids benefit health. It only reinforces the need to get plenty of omega-3s through your diet or supplements. My longstanding recommendation has been to consume two to three servings of fish per week or to take a fish oil supplement if you don't like fish. I eat fish often and also take 2-3 grams of supplemental fish oil a day.

Green Tea

The health benefits of Green Tea have long been discussed by health guru’s and have been generally thought of and defined as "an immune system enhancer." The following study published by American Journal of Clinical Nutrition was therefore of particular interest. One interesting aspect of the study depicts the benefits of green tea for women only. The study is as follows:

Japanese women who drink even a little bit of green tea seem to have a lower risk of developing pneumonia, and those who drink five or more cups per day may be able to cut their risk by 47 percent. These findings are from a study published in the September 2009 American Journal of Clinical Nutrition. The researchers also found that drinking a single cup of green tea daily cut the risk of dying from pneumonia by 41 percent. But these results apply only to Japanese women, not men. Even with the gender differences, the investigators noted that their findings support the hypothesis that compounds in green tea can destroy or inhibit the growth of viruses and other microorganisms that cause pneumonia. This was a big study that followed more than 19,000 men and more than 21,000 women for more than 12 years. The participants' ages ranged from 40 to 79. The researchers saw the benefits in women (but not men) after controlling for age, physical function, smoking status and other health and dietary factors that might influence the risk of pneumonia.
