Higher Free Radicals and Lower Antioxidants in Perimenopause

In an investigation of the relationship between biochemical parameters and oxidative indicators in perimenopausal women, researchers found that women in perimenopause are under increased oxidative stress.  Women in perimenopause had higher total cholesterol values, their levels of antioxidant enzymes were lower, in addition to carrying a larger load of free radicals (lipoperoxides).  This study would suggest that peri-menopausal and menopausal women may benefit from higher intake of antioxidants through food and/or supplementation.

Zinc Supplementation May Prevent Breast Cancer

A new Canadian study concludes that supplementation of zinc in premenopausal women, and supplementation of a multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc in postmenopausal women for 10 or more years may protect women from developing breast cancer.

3 Questions to Determine Your Diabetes Risk

A preliminary study found that being age 55 or older, having a body mass index (BMI) greater than 30, and having a family history of diabetes predicted a higher risk of developing type 2 diabetes over five years, compared with those who were under 55 with a BMI less than 25 and no family history of diabetes. While you can’t change your age or family history, you can lose weight and remove that third risk factor. Naturopathic doctors have a number of tools to help with weight loss.

New Research on Omega 3’s, Omega 6’s and ADHD

Students with higher levels of the omega 3 fatty acids EPA/DHA reported less anxiety and better word recall compared to children with higher omega-6 levels, who had measurable attention deficits that correlated to lower reading and spelling levels. Researchers conclude that suboptimal omega-3 levels may contribute to attention deficit hyperactivity disorder (ADHD) and related developmental problems.
