Red wine reduces illness of old age 

Recent studies have long touted a compound known as resveratrol found in red wine, grapes and other fruits as a cure for various diseases and a preventative against aging.
Now, a new study by the University of Florida has revealed that the polyphenol compound- an antibiotic substance produced by plants as a defense against microorganisms- may not prevent old age, but it might make it more tolerable.

“We’re all looking for an anti-aging cure in a pill, but it doesn’t exist. But what does exist shows promise of lessening many of the scourges and infirmities of old age,” said  Heather Hausenblas, psychologist at UF.

A comprehensive review of human clinical research on resveratrol has found it has ‘anti-aging, anti-carcinogenic, anti-inflammatory and antioxidant properties’, but more research on its benefits is needed, she said.  The  review shows that resveratrol has potential to improve health and prevent chronic disease.

Obese girls at more risk to be addicted to smoking
Obese adolescent girls have more than twice the risk for high-level nicotine addiction in young adulthood, according to a new study.   

Smoking is just one of the problematic behaviors that appeal to some teens, along with delinquency, drug use, alcohol use and early or unprotected sexual activity.  Some of the risk factors that could lead teens to engage in these behaviors include low self-esteem, depression and poor academic performance.

Obese teenage girls in the study were more likely to report each of these risk factors. “As we address the issue of obesity, it is important to prevent poor medical outcomes, but we must also recognise the risk for these psychosocial outcomes and support and counsel teens appropriately,” said lead author Aliya Esmail Hussaini.

Ingredient in coffee helps fight Alzheimer’s disease
A new study by University of South Florida researchers has found that a yet unidentified component of coffee that interacts with the beverage’s caffeine boosts blood levels of a critical growth factor that seems to fight off the Alzheimer’s disease process.

Using mice bred to develop symptoms mimicking Alzheimer’s disease, the USF team presented the first evidence that a caffeinated coffee offers protection against the memory-robbing disease that is not possible with other caffeine-containing drinks or decaffeinated coffee.

The new study shows that caffeinated coffee induces an increase in blood levels of a growth factor called GCSF (granulocyte colony stimulating factor). GCSF is a substance greatly decreased in patients with Alzheimer’s disease.

“Caffeinated coffee provides a natural increase in blood GCSF levels,” said USF neuroscientist Chuanhai Cao, lead author of the study.  Higher blood GCSF levels due to coffee intake were associated with better memory.
