Coffee May Delay Alzheimer’s

According to the latest studies, researchers claimed that three large cups of coffee a day could help to slow the progress of Alzheimer’s disease and may even reverse the condition.

Researchers from the University of South Florida studied 55 mice that had been genetically engineered to develop dementia symptoms identical to those of Alzheimer’s as they aged. Before treatment the mice, which were aged 18 to 19 months, about 70 years in human terms, had performed poorly in the memory tests.

Half the mice were given a daily dose of caffeine in their drinking water — equivalent to a human consuming about six espresso shots or 500mg of pure caffeine; while the other half continued to drink ordinary water. By the end of the two-month study, the caffeine-drinking mice were performing far better on tests of memory and thinking than mice given water. Their memories were as sharp as those of healthy older mice without dementia.

How to get 500mg caffeine a day?

  • 2 x 250mg caffeine pills
  • 3 x large espresso-based coffees
  • 6 x cans of Red Bull
  • 14 x cans of Coca-Cola
  • 15 x cups of tea
  • 7kg (16 lb) of chocolate

Seems like 14 cans of Coca-Cola a day isn’t so viable. Maybe 2 large espresso and 2kg of chocolate a day is more viable?

Coffee May Protect Women

Good news for female coffee drinkers!

Drinking large amounts of coffee, even up to six cups a day doesn’t increase the risk of an early death, instead it appears to protect women from fatal heart attacks and stroke, new study suggests.

Harvard School of Public Health researchers looked at coffee drinking and the risk of dying from heart disease, cancer or any other cause. They found that people who drank more coffee were less likely to die during 18 years of follow-up in men, and 24 years of follow-up in women.

Women who drank two to five cups of coffee a day were up to 26 per cent less likely to die than abstainers mainly because of a lower risk of death from heart disease. While, women who drank two to three cups of caffeinated coffee daily were 25 per cent less likely to die from cardiovascular disease than “non-consumers.”

Those who drank more four to five daily cups of coffee saw their odds fare even better, to 34 per cent reduced risk.

Researchers found similar patterns for men, but the numbers didn’t reach statistical significance, meaning they may be due to chance.

Yes, Coffee Really Can Be Good for You

Drinking coffee can help ward off type 2 diabetes and may even help prevent certain cancers, according to panelists discussing the benefits — and risks — of the beverage at a scientific meeting.

“We’re coming from a situation where coffee had a very negative health image,” Dr. Rob van Dam of the Harvard School of Public Health, who has conducted studies on coffee consumption and diabetes, told Reuters Health. Nevertheless, he added, “it’s not like we’re promoting coffee as the new health food and asking people who don’t like coffee to drink coffee for their health.”

Van Dam participated in a “controversy session” on coffee at the Experimental Biology 2007 meeting underway in Washington, D.C.

Dr. Lenore Arab of the David Geffen School of Medicine at UCLA also took part, presenting results of a review of nearly 400 studies investigating coffee consumption and cancer risk.

There’s evidence, Arab noted, that the beverage may protect against certain types of colon cancer, as well as rectal and liver cancer, possibly by reducing the amount of cholesterol, bile acid and natural sterol secretion in the colon, speeding up the passage of stool through the colon (and thus cutting exposure of the lining of the intestine to potential carcinogens in food), and via other mechanisms as well.

However, Arab did find evidence that coffee may increase the risk of leukemia and stomach cancer, with the case for leukemia being strongest.

The findings suggest that people who may be vulnerable to these risks — for example pregnant women and children — should limit coffee consumption, van Dam noted in an interview.

He and his colleagues are now conducting a clinical trial to get a clearer picture of the diabetes-preventing effects of coffee, which were first reported in 2002. Since then, he noted, there have been more than 20 studies on the topic.

Van Dam and his team are also looking for which of the “hundreds to thousands” of components of coffee might be responsible for these effects. It’s probably not caffeine, he noted, given that decaf and caffeinated coffee have similar effects on reducing diabetes risk.

His top candidate, van Dam says, is chlorogenic acid, an antioxidant that slows the absorption of glucose in the intestines.
