      Too Much of a Good Thing? Curb Caffeine Consumption for Better Health

      October 1, 2011 /

      Is there such a thing as too much coffee?

      Say it isn’t so!

      Some of us rely on coffee consumption to fuel our daily routine.

      But is it possible to drink too much?

      Scientists agree that “moderate” coffee consumption, defined as two to four brewed cups of a coffee a day, is not harmful in the long-term and likely will not produce any unwanted short-term side effects for a person who is not overly sensitive to the effects of caffeine.

      Some research shows, however, that consuming more than four cups a day can raise the incidence of heart problems as well as increase the chances of calcium loss, which can lead to osteoporosis. This is in addition to the more familiar short-term consequences of caffeine overload: irritability, restlessness, nervousness and not blinking.

      Daily Aspirin Therapy Tied to Loss of Vision

      October 1, 2011 /

      Although daily aspirin therapy is recommended to prevent heart attack and stroke it has been shown to contribute to macular degeneration in seniors.

      The study, published in the journal Ophthalmology, included Norwegian, Estonian, British, French, Italian, Greek and Spanish seniors.

      Of the 839 people who took aspirin each day, 36 had an advanced form of the disease called wet macular degeneration.

      This equates to about four out of every 100 daily aspirin users.

      In comparison, roughly two out of every 100 people who took aspirin less frequently had the same type of macular degeneration.

      Women Have Stronger Immune System than Men

      Women have stronger immune systems than men

      Maybe that’s why women live longer than man.

      Women are known to have a lower incidence of cancer — men have a two- to five-fold greater risk of developing the disease. Women are also better able to survive trauma, and, according to some reports, don’t get as seriously ill from bacterial and viral infections.

      In a new paper, researchers from Ghent University in Belgium argue these sex-specific health disparities may be due, at least in part, to tiny pieces of genetic material called microRNAs. The main function of microRNAs in cells is to turn off, or “silence,” specific genes. The researchers say microRNAs located on the female X chromosome may give women an immune system advantage over males.

      Women Stay Happy with Coffee

      September 28, 2011 /

      Drinking coffee can keep you happy, studies show; especially if you are a woman!

      So, there are more reasons to enjoy and indulge in a wonderful pastime that relaxes and soothes.

      The study is published in the Archives of Internal Medicine .

      “We found that women with the highest coffee intake — those in the top 20% — had a 20% lower risk of developing depression,” says researcher Alberto Ascherio, MD, DrPH. “The top 20% drank about the equivalent of four cups of coffee per day.” Ascherio is professor of epidemiology and nutrition at the Harvard School of Public Health and professor of medicine at Harvard Medical School.
