Diet is a powerful force as we say time and again. Most of the studies revolve around the physical aspects: inflammation, disease risk, body composition, blood markers, etc. But there’s the promise a good diet can offer other elements of health, including cognitive performance. With climbing rates of dementia and Alzheimer’s, these correlations are nothing to shake a stick at.
In that vein, this recent study caught our eye. Researchers from the University of Muenster in Germany followed subjects who had been grouped into three practices: a caloric restriction group (30% cut in daily intake), a group that increased their consumption of essential fatty acids (20% increase), and a control group. After three months, all subjects retook tests focused on memory activities. The group that cut its calories showed a “significant increase” in scores related to verbal memory. The apparent cognitive improvement could be correlated, the researchers say, with “decreases in fasting plasma levels of insulin and high sensitive C-reactive protein.” No noteworthy changes were seen in the other subjects.
From a reader email:
Let me say that I thoroughly enjoy your web site and have been digging in to it since I discovered there are people and indeed a whole movement doing what I have believed in for quite a while. I never knew I had such an untapped support group! My search and practices started years ago after reading Paul Shepard’s “Coming Home to the Pleistocene” and of course Cordains “The Paleo Diet”.
You’ve probably noticed that we like to revisit subjects, no matter how exhaustive our prior analysis may have appeared. We do this for two reasons – to foster a running dialogue on a constantly evolving idea; and to make sure the Primal Blueprint remains supported by hard science.
Mark has always talked about his affection for the beach sprint (or any type of sprint) as a quick, intense, effective cardio workout in line with the type of daily activities Grok performed. He’s also conveyed his unease with our increasing reliance on Big Pharma for our health and wellness needs. Today’s post deals with two recent studies of particular interest and relevance to these topics. We found them quite interesting, and we think our readers might too.
For better or for worse, we’re hell bent on finding or concocting the “perfect” non-caloric sweetener in this country. Call it the spirit of creative innovation – or capitalist enterprise. Call it incessant perpetuation of Americans’ bad eating habits. Call it a pragmatic step toward at least a more healthful alternative for what people will eat regardless.
First it was the pink packets, then the blue, then the yellow, and now the pleasantly, nature-inspired white and green foliage-designed envelopes. Truvia is a lucrative marketing merger of the “true,” (the essence?, the genuine?, the handy emotional affirmation?) with the herb stevia and all its natural (or novel) associations, depending on your familiarity with the natural foods (er, dietary supplement) arena.
Running wild through the internet like a greased pig at a county fair, it’s the bacon explosion. The bane of vegetarians and the New York Times, but is it unhealthy or is it Primal? Feel free to chime in.
HFCS foods may contain mercury and Modern Forager tells all. Really, sometimes picking on HFCS is just too easy.
I received a few emails this week from frustrated readers who had read a post from Fitness Fixation discussing the struggles of low carb dieting. While I don’t agree with much (anything?) of what the nutritionist has to say, I do believe many people jump into low carb dieting without much knowledge on how to eat right. The result is a diet low in both carbs and fat, thus not enough fuel to maintain strength and energy. Let me know what you think.
