Light has been cast on the interaction between broccoli consumption and reduced prostate cancer risk. Researchers found that sulforaphane, a chemical found in broccoli, interacts with cells lacking a gene called PTEN to reduce the chances of prostate cancer developing.
Chokeberry’s health-promoting effects may be due to the potent anti-inflammatory properties of its anthocyanins (an antioxidant). In addition, certain anthocyanins, including those found in chokeberry, have also been shown to improve blood sugar and the function of insulin.
The purpose of a recent study was to determine the effect of glucosamine and chondroitin on the progression of osteoarthritis of the knee. The results of this meta-analysis suggest that daily administration of glucosamine and chondroitin over two to three years may delay the progression of osteoarthritis of the knee.1
A scientific paper published in this week’s Canadian Medical Association Journal recommends adults double their intake of vitamin D, which helps the body absorb calcium. Health Canada suggested in 2002 that adequate daily vitamin D intake is 200 international units, while older adults require a minimum of 400 IUs. New guidelines published in the medical journal recommend daily supplements of 400 to 1,000 IUs for adults under age 50 without conditions affecting vitamin D absorption. Adults over 50, meanwhile, should take between 800 and 2,000 IUs a day.
Women being treated for infertility who also received supplements of DHEA were three times more likely to conceive than women undergoing infertility treatment without DHEA. Women in infertility treatment supplementing with DHEA were also more likely to experience a healthy pregnancy and delivery.
The UAB researchers have decoded a complete cascade of signals within breast tumour cells activated by virgin olive oil, and have concluded that benefits include decrease in the activity of the oncogene p21Ras, changes in protein signaling pathways, stimulation of tumour cell death and prevention of DNA damage.
Juvenile idiopathic arthritis causes persistent pain, swelling, stiffness and loss of motion in the joints. Research has indicated JIA as an autoimmune disorder and that heredity and environment seem to play a role. Scientists suspect that it is a two-step process. First, something in a child’s genetic makeup gives him or her a tendency to develop JIA; then an environmental factor, such as a virus, triggers the development of the disease.
