Science News Roundup

While we here at MDA like to pay close attention to our bodies and use common sense to help determine what is and isn’t healthy, actual scientific evidence forms the backbone of our philosophies. We scour breaking health and nutrition news releases to make sure our ideas are supported by science. It’s important, we think, to present a multifaceted case for the Primal Blueprint as the ideal lifestyle choice, because years and years of being barraged by low-fat diets and rabid calorie-counting espoused by “experts” has inured your average person against the PB.
These studies obviously weren’t conducted with the Primal Blueprint in mind, but each one lends credence to our basic ideas.
We’ve talked about the benefits of intense exercise  before. Hell, lifting heavy weights and short, intense bouts of output are hallmarks of the Primal Blueprint . For the most part, though, our previous discussions only tout the strength building, fat burning, and life extending powers of high-intensity workouts (only?!?). Okay, those benefits are reason enough to institute a regimen of regular exercise into your life, but a new study suggests that high-impact movements can improve bone health and muscle strength in teens .
Remember those PE warm-ups where the whole class would stretch for ten minutes, maybe do some half-hearted jumping jacks? For eight months, scientists did away with those in favor of a jumping regimen: tuck jumps , jumping jacks, side lunges , and skipping. The results were impressive. Boys saw overall bone mass increase (while also losing fat mass, but that’s not surprising), while girls’ bone mass improved most at the hip and spine.
The importance of eating fruits and vegetables is one area where PB and popular opinion converge. Everyone knows you’re supposed to eat tons of plant matter, cause, well, eating a big plate of broccoli and spinach just feels right (tasting right, for far too many people, is a different story). But what if that broccoli could actually fight the flu? A new study shows  that mice given quercetin, a substance found in broccoli, tea, red wine, red onion, grapes, and blueberries were less likely to contract the flu. Even when stressful exercise was introduced and shown to increase the mice’s susceptibility to the flu, quercetin nullified it. Sound perfect for Primal man on the hunt, no? Eat your vegetables (and drink your wine), kids – Grok did!
We’re in love with sleep, as you know. Who isn’t? There’s nothing better than a well-deserved deep snooze after a stressful day, and science is fast suggesting that it can do wonders for your physical and mental health. Plus, Mom was always pretty adamant that you get plenty of sleep, and she’s never wrong, right?
More evidence is mounting to support her. A new UCLA study found  that even a single night of lackluster slumber can cause tissue inflammation. In and of itself, the inflammation isn’t something to worry about too much. But there is a suspected link between chronic inflammation and a wide range of common disorders, and this new data has “[closed] a gap” in scientists’ understanding of how sleep loss might affect this relationship.
Nothing conclusive yet, but it’s compelling. While we do wait for more studies, it’s probably a good idea to just sleep on it.
