Your Brain On Alcohol

Posted on by

No definitive smoking gun on alcohol use has yet been presented, but the evidence leans heavily against it. Two very large direct studies and one huge meta study have recently appeared, and they largely point to increased risk of dementia as well as of cardiometabolic disease (includes stroke, coronary heart disease, and diabetes).

Mediterranean Diet Appears to Prolog Life in Elderly

Posted on by

It’s already well-known that the Mediterranean Diet appears to be quite beneficial for heart health, and to aid in resisting atherosclerosis and type 2 diabetes:

What’s to know about the Mediterranean diet?

In addition, the Mediterranean Diet has been shown to significantly reduce the risk of dementia:

Now, a new study has suggested that adopting the Mediterranean Diet, even in old age, can prolog life. Here are two media articles on the study, together with a link to the study abstract:

Diet Soda And Dementia And Stroke

Posted on by

Just about a year ago, a study examining the associations of drinking artificially sweetened soda drinks made something of a splash. The study found that people consuming at least a can of so-called diet drinks every day were 2.96 times more likely to suffer an ischaemic stroke and 2.89 times more likely to develop Alzheimer’s disease than those who drank them less than once a week. The study — like many — could not establish a causal relationship either way, only a definite association. But “the best current evidence suggests that when it comes to reducing your risk of dementia, what is good for your heart is also good for your head.”

Here are four media articles about the work:

Japanese Diet May Help Extend Life

Posted on by

Many articles and studies have extolled the health benefits of the Mediterranean diet (Search for Mediterranean under Health > Diet). Now the “Japanese diet” has entered the field.

Life expectancy in Japan is among the highest in the world, with Japanese women having the longest life expectancy of anyone in the world, with an average age of 87.

The study enrolled 36,624 men Japanese and 42,920 Japanese women between the ages of 45 and 75, and followed them for 15 years. Those participants who closely followed government recommended dietary guidelines were 15% less likely to die over the 15 years, and were 22% less likely to die of stroke during those 15 years,

“Our findings suggest that balanced consumption of energy, grains, vegetables, fruits, meat, fish, eggs, soy products, dairy products, confectionaries, and alcoholic beverages can contribute to longevity by decreasing the risk of death, predominantly from cardiovascular disease, in the Japanese population,” the authors wrote.

Links to articles about the study, together with the study itself, have be published in Health > Diet:

Green For Health

Posted on by

Old novels would send heroes and heroines (especially) to the country to recover from physical and/or mental maladies. Cliche or not, getting near at least some green is good for your health and longevity. Small studies have pointed at this over the years, but now a massive new 108,000-woman study, based on the Nurse’s Health Study, seriously quantifies this. In particular, the death rate of women living in the greenest areas was 12% lower than women living in the least green areas. Compared to women living in areas with less greenery, the researchers found that women in greener areas had:

  • lower levels of depression
  • 41% lower death rate for kidney disease
  • 34% lower death rate for respiratory disease
  • 13% lower death rate for cancer

The study results don’t say that you should immediately abandon city living and head for the country. But they do suggest that greater amounts of green in the immediate environs of your home will help your health.
