Health Watch: Caffeine & Alzheimer’s

We just read this fascinating article about a study from earlier this year that indicates regular coffee consumption can decrease the risk of developing dementia or Alzheimer’s later in life.

Researchers found that caffeine may cut the risk of dementia because of its ability to block the adverse effects of high cholesterol on the body’s systems — one of which may be the breakdown of the blood/brain barrier that protects our brain tissue from potentially harmful chemicals in our bloodstream. There have been previous studies to indicate that the breakdown of this barrier may contribute to the development of dementia and Alzheimer’s.

The research centered on rabbits, which were given a high cholesterol diet over a 12 week period, some of which were also given the equivalent of one cup of coffee per day. At the end of the trial, researchers found that the blood/brain barrier in the rabbits that had the coffee supplement was far less deteriorated than the rabbits with no supplement. The results of this research are a very interesting step in determining both new restoration therapies and preventative
care.

So sip your daily joe knowing that it’s not only delicious — it’s brain food!

Health Watch: Caffeine & Breast Cancer

A new joint study out of Harvard and Tokyo indicates that caffeine consumption may not be a strict carcinogen. It found no statistically reliable evidence that drinking coffee increases overall breast cancer risk, but it did find data regarding how it effects pre-existing breast tissue conditions, requiring further study.

The researchers reviewed the medical and dietary records of nearly 40,000 women since a baseline taken between 1992 – 1995, and examined the commonalities between their dietary intake and the development of breast cancer. They were unable to find any statistical¬† proof that caffeine did in fact increase a woman’s risk of breast cancer, but they did notice that those with higher caffeine intake (more than 4 cups per day) did experience adverse effects in the state of pre-existing benign breast disease and tumors.

While it appears that minimal intake my not increase your risk — if you’re a coffee lover with a history of breast cancer in your family, it might be a good idea to switch to decaf (just to be on the safe side!).
