Soy Compound May Halt Spread of Prostate Cancer

A compound found in soybeans almost completely prevented the spread of human prostate cancer in mice.

Investigators from Northwestern University found that genistein decreased metastasis of prostate cancer to the lungs by 96 percent compared with mice that did not eat the compound in their chow - making the study the first to demonstrate genistein can stop prostate cancer metastasis in a living organism.

Degenerative Eye Disease Doubles Heart Attack and Stroke Risk

The progressive eye disease, age related macular degeneration, or AMD for short, doubles the risk of dying from a heart attack or stroke. AMD affects the centre of the retina (macula) at the back of the eye, which is used for fine central vision tasks, such as reading and driving.

Among people under the age of 75 at the start of the study, early AMD was associated with a doubling in the risks of dying from a heart attack or stroke within the next decade. And those with late stage disease at the start of the study had five times the risk of dying from a heart attack, and 10 times the risk of dying from a stroke.

Cartotenoids Reverse AMD

Carotenoids are antioxidants that produce the bright red, orange, yellow and green colors of vegetables and fruits. Notable carotenoids include lutein, Zeaxanthin, beta-carotene, and lycopene.

A new study shows that carotenoids benefit eye health and age-related macular degeneration (AMD). The researchers found that those in the untreated AMD group had no changes in their mfERG. Those in the supplement groups had “a reduction in mfERG impairment” around the center of the retina (and thereby an improvement in AMD symptoms) that was observed by six months. The researchers felt that the supplement improved overall nerve cell health in the eye.

Association Between Inflammation and Homocysteine Levels?

Researchers have found that people who consume higher amounts of choline and its metabolite betaine have lower levels of inflammation and lower levels of homocysteine. Inflammation was measured by C-reactive protein, interleukin-6 and tumor necrosis factor-alpha; homocysteine is an amino acid implicated in heart disease.

The researchers concluded, “Our results support an association between choline and betaine intakes and the inflammation process in free-eating and apparently healthy adults.”

Higher Levels of DHEAS Associated with Better Cognitive Function

Women with naturally higher levels of the hormone precursor DHEAS were found to have better cognitive function than women with lower levels.

DHEA is a steroid precursor, which means that it is converted in the body to steroid hormones such as testosterone and estrogen. It is the most abundant circulating sex steroid in women.

The researchers speculate that there may be a number of explanations for their findings, including direct action of DHEA and DHEAS, DHEAS being a marker of androgen and estrogen production in women, or simply DHEA and DHEAS levels being markers of general good health.

Soy Isoflavone Intake Increases Bone Mineral Density in Post Menopausal Women

Osteoporosis, a decrease in the density of the bones leading to susceptibility to fracture, is very common among post-menopausal Caucasian women. Since before menopause, estrogen levels are higher, estrogen replacement therapy is sometimes prescribed for post-menopausal women at risk for osteoporosis who want to minimize bone mineral loss. However, the effects of estrogen on the body are complex, so estrogen replacement comes at a price, including increased risk for heart disease and breast cancer.

The ten studies included in the meta-analysis examined soy protein intake over a period of six months or more in peri or post-menopausal women. Results were reported using changes in spine bone mineral density (SBMD) and spine bone mineral content (SBMC) from baseline.

Intake of isoflavones significantly increased SBMD by 20.6 mg/cm2.

Researchers Show Leaky Muscle Cells Lead to Fatigue

The fatigue that marathoners and other extreme athletes feel at the end of a race is caused by a tiny leak inside their muscles that probably also saps the energy from patients with heart failure.

The leak – which allows calcium to continuously leak inside muscle cells – weakens the force produced by the muscle and also turns on a protein-digesting enzyme that damages the muscle fibers. The calcium leak also provides a new explanation for the muscle soreness and fatigue that marathoners and other athletes can experience for weeks after crossing the finish line.

Low dose supplementation with L-carnitine tartrate may reduce muscle damage and boost recovery after exercise.

Probiotic Cuts Flu Rate

The probiotic Lactobacillus substantially cuts the rate and length of respiratory illness in professional long distance runners. Intensive exercise can subdue the normal immune response, and as a result, some athletes are vulnerable to respiratory viruses, such as colds and flu.

Athletes taking the probiotic had less than half the number of days of symptoms of their colleagues taking the placebo. Respiratory symptoms while taking Lactobacillus lasted 30 days compared with 72 days while taking the placebo. Symptoms also tended to be less severe.
