Lycopene in Tomatoes & Prostate Cancer

Written by Gloria Tsang, RD

Lycopene, a powerful antioxidant, is found abundant in tomatoes and tomato products. Studies found that lycopene may help reduce some cancer and heart disease. The most compelling evidence so far is the role of lycopene in prostate cancer prevention.

In a study of over 40,000 health professionals, Harvard investigators found that men who ate more than 10 servings tomato-based foods daily (like cooked tomatoes and tomato sauce,) had a 35 percent lower risk of developing prostate cancer than those who ate the least amount of these foods. The benefits of lycopene was more pronounced with advanced stages of prostate cancer.

In another study of prostate cancer, researchers looked at blood levels of lycopene and found that the risk of developing prostate cancer, especially aggressive cancer, decreased with increasing blood lycopene levels. Men taking 50mg of lycopene daily had significantly higher level of lycopene. In this study, researchers found that high level of lycopene in the blood was associated with low PSA (prostate specific antigen) levels. High PSA levels in blood are often a sign of prostate cancer.

Enjoy the benefits of lycopene by eating more tomatoes and processed tomato products. Indeed, research showed that lycopene is better absorbed by the body when tomatoes are processed. It is due to the fact that lycopene is bound to tomato’s cell structure; processing releases lycopene from the cell structure.

Possible Benefits of Fish Oil on People With Diabetes

Article compliments of Health Castle

(HealthCastle.com) Researchers from the Norwegian University of Science and Technology in Norway studied the effect of fish oil supplements on blood lipoprotein in 26 people with Type 2 diabetes. The study participants were assigned to take either fish oil or corn oil supplements. Size and concentration of lipoproteins subclasses (several blood cholesterol markers) as well as insulin sensitivity were measured after nine weeks of supplementation. High doses of fish oil reduced the size and concentration of several lipoprotein subclasses while lowering insulin sensitivity. Results of this study were published online on the European Journal of Clinical Nutrition website on Feb. 28, 2007.

Editor’s Note – Multiple Benefits of Fish Oil and Omega 3
Benefits of fish oil and omega 3 fatty acids are well known for their role in heart disease prevention. The American Heart Association advises heart disease sufferers and people with high triglyceride levels to take fish oil supplements. Recent studies suggest that fish oil may prevent dementia and ease depression. Clinical studies regarding the effects of fish oil on diabetes are still preliminary, however.

How much Fish Oil? For heart health benefits, experts suggested to aim for 250 milligrams as EPA/DHA from fish source a day. One three ounce serving of fatty fish, such as salmon or mackerel, provides more than 1000 milligrams alone. For people with documented heart disease or high levels of triglycerides, the American Heart Association suggests 1,000 milligrams per day and 2,000 to 4,000 milligrams per day, respectively.
