Signs of brain shrinkage

A new study published in Neurology found that the puffier the brain gets in the middle ages, the larger is the chance of brain shrinkage and Alzheimer's disease later in life. Higher levels of inflammation were also associated with poorer performance on the memory test. The researchers studied 1,633 people who were in their early 50s, in 1987-89, for 24 years. The MRI on their brain volume showed a sharp decrease along with a low mental agility - reflected by a poor performance in a word-memorisation task.

Red meat tied to 9 diseases

The more red meat you eat, the greater is your risk of dying from one of nine diseases, says a British Medical Journal report that tracked the diet of 5,36,000 people aged 50-71 for 16 years. Intake of total meat, processed and unpro-cessed red meat (beef, lamb, pork), and white meat (poultry, fish) was recor-ded. Those who consu-med more red meat had a higher death rate from cancer, heart and respiratory diseases, stroke, diabetes, infections, Alzheimer's, kidney and liver diseases.

Cut endometriosis risk

Endometriosis - the growth of uterine tissue outside the uterus - can cause severe pain and excessive bleeding during menstruation. It's a chronic disorder with an unknown cause. A large study on 72,394 women found those who nursed for a year or more had a 32 per cent reduced risk for endometriosis. For each additional three months of nursing, they reduced their risk by 8 per cent.

The mechanism remains unclear, but women who stopped having periods for a time after giving birth also reduced their risk, and breast-feeding prolongs the pause in menstruation. Still, menstrual delay accounted for only a portion of the effect.
