Red wine apparently mimics the effects of aromatase inhibitors, which play a key role in managing estrogen levels.
Large-scale longitudinal study links low blood levels of Vitamin D to depression.
Among older women who strength train, supplementation with omega-3 helps to enhance the benefits on muscle.
Increased carbohydrate – particularly starch – intake associates with a higher rate of breast cancer recurrence.
Among carriers of the apolipoprotein E (APOE) epsilon-4 genotype, staying active slows the buildup of amyloid plaques in the brain.
Life expectancy for patients with Parkinson's disease is poorer than some previous studies have suggested, with barely one-third of patients surviving six years
Large-scale prospective study reveals that on all cognitive measures except vocabulary, linear declines start as early as age 45.
Men and women who have a high body mass index (BMI) for a long period of time are at an increased risk of type-2 diabetes
Listening to music lessens the pain response, particularly among people who are anxious about undergoing a medical procedure.
Adiponectin, a hormone derived from visceral fat, may play a role as a risk factor for development of all-cause dementia and Alzheimer's Disease in women.
ANTI-AGING TIP OF THE DAY
Activity Boosts Quality
Among older women, modest amounts of exercise can improve quality of life (QOL). Researchers from the Pennington Biomedical Research Center (Louisiana, USA) completed a six-month study involving 430 sedentary postmenopausal women (BMI of 25.0-43.0, with elevated systolic blood pressure).
Each subject was assigned to participate in 1 of 3 exercise groups (exercising 1 hour 15 minutes/week; 2 hours 20 minutes/week, or 3 hours/week) or the nonexercise control group...

Fish oil is rich in n-3 (omega-3) polyunsaturated fatty acids, which have been shown to play a role in the plasma membrane and cell function of muscles. CL Rodacki, from Parana Federal University (Brazil), and colleagues studied 45 women, average age 64 years, all of whom engaged in a 90-day long strength training regimen. Fifteen of the study participants received 2 g of fish oil (0.4 g EPA and 0.3 g DHA) per day during the 90 days of strength training, and another 15 women received fish oil for 60 days prior to strength training as well as during the 90 days of training. Among the women given fish oil supplement, the researchers observed an improvement in muscle torque, as well as better performance in chair-rising exercises. Reporting that: “The inclusion of [fish oil] supplementation caused greater improvements in muscle strength and functional capacity,” the study authors conclude that: "Strength training increased muscle strength in elderly women.”
