Just When You Thought It Was Safe

Recently there have been medical research reports indicating that all the warnings about consuming too much salt were exaggerated. Perhaps you remember when we were told that consuming eggs would clog our arteries with cholesterol, and anyone eating butter had a death wish. Now, eggs are an ideal source of lean protein and butter not only isn’t bad, it is superior to margarine.
In that vein, having seen the newer reports, I was largely ignoring salt warnings (particularly since I can eat my weight in restaurant chips and salsa). Then this report popped-up.



Quoting from the study: “…excess dietary salt suppresses resting cerebral blood flow and endothelial function, leading to cognitive decline.”  Cognitive decline, of course, isn’t good. It causes little brains.

Research Details
Researchers from Weill Cornell Medical College fed mice a high salt diet. Admittedly, it was a very high salt diet. The result was reduced blood flow to the hippocampus and cortex. Our old friend the hippocampus, which we seem to mention in every newsletter, is critical to memory.  Now, usually when salt is involved, a negative impact on blood pressure is the first suspect. However, the researchers determined that wasn’t the cause of the mice losing their memories about basic stuff such as how to make a nest. But rather it was caused by cells in the intestine signaling the brain to make adjustments. A new discovery in the “gut-brain” axis.  I won’t attempt to go through the science but think twice before reaching for the salt shaker. Research linked here . And feed those little microbiome critters living in your intestinal tract some of their favorites such as yogurt and root vegetables to keep them happy.


But There Still Are Some Pleasures
If you missed it, last week we noted that you probably aren’t eating enough  chocolate , and, unless you are drinking a whole pot per day, you aren’t drinking enough coffee either.


Further, just for your benefit, we noted that we offer our own gourmet, freshly roasted, small batch, whole bean coffee. And it is so much better than those K-cups full of stale instant coffee that you’ll notice the difference immediately.

Book Review: What Matters Now by Gary Hamel

Interview of Eric Schmidt by Gary Hamel at the MLab dinner tonight. Google's Marissa Mayer and Hal Varian also joined the open dialog about Google's culture and management style, from chaos to arrogance. The video just went up on YouTube. It's quite entertaining. (Photo credit: Wikipedia)Cover of The Future of ManagementMy list of must-read business writers continues to expand.Gary Hamel, however, author of What Matters Now, with the very long subtitle of How to Win in a World of Relentless Change, Ferocious Competition, and Unstoppable Innovation, has been on the list for quite some time.Continuing his thesis on the need for a new approach to management introduced in his prior book The Future of Management, Hamel calls for a complete rethinking of how enterprises are run.

Fundamental to his recommendation is that the practice of management is ossified in a command and control system that is now generations old and needs to be replaced with something that reflects an educat…

7 Ways to Fix Your Gut and Help Your Brain

Author Peter Andrey Smith titled his article on the relationship of the brain to the intestines, and, in particular, the tiny creatures that live in our intestine beautifully: “The tantalizing links between gut microbes and the brain”. If the human brain is the frontier of medical science, the microbiome, those tiny creatures that live in our intestinal tract, is Jupiter. The linkage between what goes on in the gut and the brain is indeed tantalizing, and the subject of research worldwide. There are over 1,000 different kinds of those things living inside us. There are hints that having the wrong mix of gut microbes, or the absence of any particular type, is linked to asthma, irritable bowel syndrome, allergies, depression, Alzheimer’s disease and more. Further, antibiotics, illnesses and other factors can deplete the population. Here are seven things we can do to help keep our little creatures happy and healthy.
Eat the right stuff. There is evidence that the right diet helps keep …

Get REM Sleep; Manage Fear

A good night’s sleep may help you manage fear and risks better.

A study just posted in Journal of Neuroscience describes the importance of a good night’s sleep to controlling strong emotions, especially fear. Previous studies in this area attempted to discover what happens in the brain after a frightful experience.  These prior studies, for example, show how Post-Traumatic Stress Disorder (PTSD) affects sleep. A team at the Rutgers University Center for Molecular and Behavioral Neuroscience, led by Itamar Lerner, has taken a different approach. They wanted to see if there is a relationship between adequate sleep and prevention or management of the brain’s reaction to subsequent stressful events. Research Team Lerner is a Postdoctoral Fellow in sleep research. Along with fellow researchers Neha Sinha-also doing Postdoctoral research-in her case in brain imaging, Shira Lupkin and Alan Tsai, they used new technology that allows mobile tracking of sleep habits over a period of time, not j…
