Diabetes Busting Burgers!

Chemists with the U.S. Department of Agriculture recently presented a preliminary report to the 229th national meeting of the American Chemical Society, in which they say they have discovered a form of soluble cellulose that, if added to high-fat food. The new finding could soon benefit people who regularly eat fast-foods that are high in fat.

Vitamin E may increase heart attack risk - does not prevent cancer

A study by Canadian researchers Eva Lonn, M.D., of the Population Health Research Institute and McMaster University, Hamilton Health Sciences Corporation, Hamilton, Ontario, Canada, and colleagues, has found from examining experimental and epidemiological data, that patients who took vitamin E supplements for 7 years did not significantly reduce their risk of cancer or cardiovascular events and some in fact had an increased risk of heart failure.

Drug combo gives lung cancer patients longer life

Preliminary results from a large randomized clinical trial, sponsored by the National Cancer Institute (NCI), by a network of researchers led by the Eastern Cooperative Oncology Group. Genentech, Inc., have shown that patients with previously untreated advanced non-squamous non-small cell lung cancer who received bevacizumab (Avastin) in combination with standard chemotherapy lived longer than patients who received the same chemotherapy without bevacizumab.

No association between acrylamide intake in foods and risk of breast cancer

Researchers from the Harvard School of Public Health and the Karolinska Institute in Stockholm, Sweden, have found no association between acrylamide intake in foods and risk of breast cancer among Swedish women. The findings appear in the March 16, 2005 issue of the Journal of the American Medical Association.

Antidepressants not the culprit in depression linked to heart attacks

The increased risk of heart attack associated with taking antidepressants may be caused by the depression itself rather than the drugs themselves, suggests new research reported in the current issue in the British Medical Journal. At least one in 10 older people are prescribed antidepressants.
