Sugary Drinks, Diet Soda & Your Brain

Soda can make you stupid, or worse. Sometimes we find research reports on brain health that are sobering. There was a rather spooky one we just read. But we also discovered one that is positive. Here’s the tough medicine first.   Artificial Sweeteners May Be Bad For You   Here’s the punch line: “Daily diet soda drinkers three times more likely to develop stroke and dementia compared to those who don’t”. You might have seen that headline before. It drew a lot of publicity. Now, remember your statistics class: correlation doesn’t mean causation. Just because the years that skirt hemlines go up are also years that the stock market goes up doesn’t mean short skirts cause the stock prices to increase. It could be that other things diet soda drinkers do – or don’t do- is the reason they are more likely to have a stroke or get dementia.   Here’s  a link to a summary of the research  if you want to read more. The research was done by a team from Boston University, led by a professor

Will Working Puzzles and Playing Strategy Games Preserve Your Brain?

If you do it right, puzzles and games might just save your brain. There are millions of players of strategy games, memory games, word games and puzzles. They want to know that working crosswords, solving sudoku, playing bridge, mahjong or chess will help preserve mental acuity. Some are counting on it. Cognitive Reserve Cognitive reserve is the term developed after researchers found instances of examination of the brains of individuals that showed signs of dementia or Alzheimer’s disease, but, while alive, the individual had exhibited no signs of dementia.  We want to build cognitive reserve, and there is evidence that puzzles can do that. One key-and positive- study from 2011 found that solving crossword puzzles delayed onset of memory loss by 2.5 years, and may have had much longer beneficial impact. NIH Research The National Institute of Health and the National Institute of Nursing Research funded a study on brain-training and cognition. That study is related-admitt

Did You Know You Have An Inner Executive? Show It Some Love

Your brain has an Executive Function . Executive function is the scientific term for our ability to organize activity, learn from past experiences, make plans, solve problems and work puzzles. Some Science Among the areas in the brain involved in executive function are the medial frontal cortex and the lateral prefrontal cortex . Robert M.G. Reinhart PhD and Assistant Professor of Psychology at Boston University notes that those two areas control most of the executive function. He calls these areas “ the alarm bell of the brain ”. Reinhart is the Director of the Visual Cognitive Neuroscience at Boston University and, among other area of brain research, has been studying ways to employ electrical stimulation to improve performance in learning and self-control. “If you make an error, this brain area fires. If I tell you that you make an error, it also fires. If something surprises you, it fires,” says Reinhart. More Science Kimberly Luu, currently doing graduate s

We're Fat as Hell and It's Killing Us

Tuesday, the CDC reported that being overweight or obese is associated with higher risk of 13 different cancers. They put it into perspective with two additional pieces of data: first, two-thirds of American adults are overweight , and second, in 2014, there were 630,000 diagnoses of those forms of cancer in the U.S. That is, there were 630,000 cases of the kinds of cancer associated with being overweight. Over a third of Americans are obese. Now, that’s not someone’s judgement call. That is a statistical finding, based on studies of body mass index (BMI). Here's the formula for BMI so that you can calculate it for yourself. You may want to convert your height and weight into meters; some of the formulas I’ve found use the metric system. Here's a converter for inches into meters. A friend of mine said he is writing a three-hundred-page book on diet. On one page it has “Eat Less”. The facing page has “Exercise More”, for all three hundred pages. There is no mystery
