Increased intakes of Vitamins C and E and beta-carotene may reduce the risk of cancer of the uterus, according to a new review and meta-analysis of the science to date. Writing in Cancer Causes and Control, US scientists report that for every 1,000 microgram increase per 1,000 calories of diet for Beta-Carotene there was a 12% reduction in the risk of endometrial cancer. Similarly, for every 50 milligram increase per 1,000 calories for Vitamin C there was a 15% reduction in the risk of suffering with endometrial cancer, and for every 5 milligram increase per 1,000 calories for Vitamin E the risk of endometrial cancer was reduced by 9%.

C-phycocyanin is a compound found in the blue green algae Spirulina; it may reduce inflammation and have pain killing effects, according to a new animal study. Increasing doses of C-phycocyanin reduced levels of inflammatory markers in rats administered carrageenan, a chemical injected into the rat’s paw that causes pain and inflammation. The researchers were led by Tz-Chong Chou from Taiwan’s National Defence Medical Center.

Researchers from the Mayo Clinic in Rochester, MN and the Ernest Mario School of Pharmacy at Rutgers in Piscataway, NJ report good results in early leukemia clinical trials using EGCG; the major active ingredient in Green Tea. The trial determined that patients with chronic lymphocytic leukemia (CLL) can tolerate the Green Tea constituent when high doses are taken in capsule form and that the lymphocyte count was reduced in one-third of the patients. “We found not only that patients tolerated the green tea extract at very high doses, but that many of them saw regression to some degree of their chronic lymphocytic leukemia,” says Tait Shanafelt, M.D., Mayo Clinic hematologist and lead author of the study.
