Eating broccoli may keep genetic skin disorder at bay

Eating broccoli is a very good idea for people suffering from a devastating genetic skin disorder, say researchers at the Johns Hopkins University School of Medicine in Baltimore, who found that a natural compound present in the green vegetable could help treat the disorder.
The disorder in question is called epidermolysis bullosa simplex (EBS), which results from mutations in the genes encoding keratin 5 or keratin 14. The mildest form of EBS leads of blistering of the hands and feet since these are most susceptible to frequent abrasion.
Researchers led by Pierre Coulombe found that the compound sulforaphane whose natural precursors are found at high levels in broccoli and other cruciferous vegetables can help meat the disorder.
Coulomb end colleagues turned to sulforaphane in their search for a chemical activator that would induce the production of missing keratins in basal epidermis.

Chemical in fried food may double cancer risk in women

A new study at the University of Maastricht has found that a common chemical called acrylamide caused by frying, roasting or grilling a food substance can double the risk of cancer in women.

The study, which enrolled 120,000 people – half of whom were women – established a direct association between consumption of the chemical and the incidence of ovarian and womb cancer.

It also revealed that the chemical is found in cooked foods such as bread, breakfast cereals, coffee and also meat and potatoes which had been fried, roasted, grilled or barbecued.

The Dutch study discovered that women who had more acrylamide were twice as likely to develop ovarian or womb cancer as those who ingested a smaller amount. The higher amount eaten by the women involved was the equivalent to a single packet of crisps, half a pack of biscuits, or a portion of chips a day.

Walking faster and outpacing death

Researchers who followed the health of nearly 500 older people for almost a decade found that those who walked more quickly were less likely to die over the course of the study published in the Journal of the American Geriatrics Society. The findings, the researchers said, suggest that gait speed may be a good predictor of long-term survival, even in people who otherwise appear basically healthy. The researchers also found that people whose walking speed improved reduced their risk of death.
