Getting more of the "Sunshine vitamin" may make you brighter later in life, according to a study that bolsters evidence vitamin D may help older people stay mentally fit.
The findings also raise the prospect that people who do not get enough of the vitamin could use supplements to keep the brain fully functioning as they age, David Lee and colleagues at the University of Manchester reported in their study, published Thursday in the Journal of Neurology Neurosurgery and Psychiatry.
NEW YORK (Reuters Health) - A new study suggests that older adults who eat diets rich in citrus fruits, leafy greens and fish oil, but low in "glycemic index," may have a lower risk of age-related macular degeneration -- the leading cause of vision loss among older U.S. adults.
AMD, also known as "age-related macular degeneration" refers to gradual damage to the macula, a structure in the retina that allows for seeing fine detail. The condition affects more than 1 million Americans, usually after the age of 65.
A number of studies have suggested that individual nutrients, including the antioxidants lutein, vitamin C and vitamin E, can help protect against AMD. This latest study, published in the journal Ophthalmology, looked at the overall diet patterns of 4,000 older adults and the links to AMD risk.
Australian researchers have found that a traditional preparation of the South Pacific herbal medicine Kava, an ancient drug long used for treating stress and insomnia, is safe and effective. A University of Queensland research team conducted a placebo-controlled, world-first clinical trial. It showed that Kava prepared by the traditional method, which uses water, is safe for treating anxiety and improving mood, while the modern European method of preparation, which uses acetone and ethanol, may be responsible for the ill side effects associated with it.

Offering clues to why smokers often gain weight after quitting, a new study suggests that smoking enhances the activity of a gene that helps break down body fat.
Researchers found that compared with non-smokers, a group of healthy smokers showed greater activity in a gene called AZGP1 in cell samples taken from their airways.
Because the gene is thought to be important in breaking down fat and controlling weight, the findings point to one possible reason that smokers tend to weigh less than non-smokers -- and why people often put on pounds after quitting. MORE>>>>>>>>>>>>>
Industrial workers who are exposed to the chemical formaldehyde may have a significantly higher risk of dying from blood and lymphatic cancers, U.S. government researchers said on Tuesday.
A study of more than 25,000 workers at industrial plants that produced formaldehyde and formaldehyde resin found workers with the highest exposures had a 37 percent increased risk of death compared to those with the lowest exposure levels, they reported in the Journal of the National Cancer Institute.

An extract made from broccoli sprouts can help protect skin from the sun’s damaging rays, according to researchers at the John Hopkins School of Medicine.
Although a commercial product is still in the early stages of development, it would have definite advantages over sunscreens:
Spending more time in the sunshine could help older people reduce their risk of developing heart disease and diabetes.
Older people are more likely to have a vitamin D deficiency because of the natural aging process and changes in lifestyle, but exposure to sunlight stimulates vitamin D in the skin.
Vitamin D deficiency is associated significantly with metabolic syndrome, a combination of medical and metabolic disorders that increases the risk of developing cardiovascular disease and diabetes, according to researchers at the University of Warwick near Coventry, England.
US scientists say they have successfully reversed the effects of Alzheimer's with experimental drugs.
The drugs target and boost the function of a newly pinpointed gene involved in the brain's memory formation.
In mice, the treatment helped restore long-term memory and improve learning for new tasks, Nature reports.
The same drugs - HDAC inhibitors - are currently being tested to treat Huntington's disease and are on the market to treat some cancers.
They reshape the DNA scaffolding that supports and controls the expression of genes in the brain.
"If women in your family give birth at older ages, you may well have a chance of living longer than you would otherwise," says the study's lead author, demographer Ken R. Smith, a professor of family and consumer studies at the University of Utah. "If you have a female relative who had children after age 45, then there may be some genetic benefit in your family that will enhance your longevity."
For descendants of the Utah and Quebec pioneers studied, "you may be able to look at the ages when your female ancestors gave birth - rather than just their longevity - in estimating how long you may live," says Smith, whose study will be published online May 4 and in the June 10 print issue of the Journal of Gerontology: Biological Sciences.
The researchers examined high-quality genealogical records from the Utah Population Database at the University of Utah with its records of 1.6 million Utah Mormon pioneers and their descendants. They also used the University of Montreal's Program on Demographic History Research, which has records on 400,000 people who lived in heavily Catholic Quebec between 1608 and 1850.
Specifically, the study involved the records of 11,604 Utah men who were born between 1800 and 1869 and who had at least one sister who lived at least to age 50; and the records of 6,206 Quebec men who lived between 1670 and 1750, and had at least one sister who lived to 50 or older. The key findings:
