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.
Conventional wisdom (our dear, dear friend) tells us that without the constant application of skin creams and face lotions and mineral moisturizers, we’ll become haggard parchment people with wrinkled mugs that’d put an elderly Sharpei to shame. It seems to have worked, too. Most bathroom mirrors conceal impressive caches of creams, lotions, and oils, and many people instinctively and compulsively lather the stuff on any chance they get (similar to our infatuation with Purell, but that’s another post altogether). But, as we’ve often wondered, is confronting a totally natural occurrence – dry skin – with unnatural methods and products really such a good idea?
I am a loyal Daily Apple reader who’s just begun a full-scale primal + IF + HIIT lifestyle. My only worry is that of muscle loss or impeded muscle growth. As a friend of multiple muscle builders, I’ve been told that carbohydrates are necessary for that muscle growth. While I’m not about to go back to my high-carb ways, I am willing to make an exception for post-lifting meals (within an hour window). I’ve heard this is the optimal time for carb-intake as your muscles are depleted of glycogen stores. I am wondering if you could shed light on this. Is this method actually effective for muscle growth? If so, how many carbs should I consume, and of what kind? And finally, will making this one compromise induce inflammation or impede fat loss?
Remember how we’re always going off about the importance of getting enough vitamin D in your life? How outdoor activity – and vitamin D producing sunlight – is important for any Primal Blueprinter? It seems some recent scientific research is again making this point for us.
First thing’s first. Mark himself (at 55 years and going strong) is a proud member of this group, and he knows many of you are too. Art De Vany, good friend to Mark and fellow Primal practitioner, is a hearty 71. In truth, there’s no shortage of exceptionally fit, strong and seasoned men and women out there, some of whom can hold their own with the fit thirty-something set.
We think being older and wiser doesn’t preclude anyone from the best of Primal living. Granted, many MDA readers in their sixties, seventies or eighties might not be up for the plyometric and sprint routines we suggest. (We’ve gotten and appreciated your emails to this effect.) Though our suggestions for Primal exercise don’t change much with age (Grok’s not letting anyone off easy here!), we freely concede that variations can offer useful alternatives for healthy later decades.
