Default Paleo Diet Studies

A read from Cordain:

Quote:
This year, the European Journal of Clinical Nutrition published a study that demonstrated that Paleo-like diets produced rapid and dramatic reductions in blood pressure, plasma insulin, total cholesterol, low-density lipoproteins (LDL) and triglycerides all in just 10 days.1 These researchers concluded that remarkably short-term consumption of Paleo-like diets provided these benefits, all without losing weight, increasing activity levels or taking any medication.1

Previous studies analyzing all of the components of the Paleo Diet (fresh fruits, veggies, lean meat, seafood, fish, nuts and certain oils that try to mimic the fatty acid profile of our ancestor's diets) had shown similar results both in healthy people2 and in individuals with ischaemic heart disease3

Although there are only three human intervention trials and one animal model study4 with a Paleo-type diet, evidence gathered from tissue, animal, epidemiological and human metabolic studies analyzing certain dietary characteristics that also exist in the Paleo Diet has led several authors to argue that Paleo-like diets reduced the risk of atherosclerotic cardiovascular disease, insulin resistance and type 2 diabetes, metabolic syndrome hypertension, age-related sarcopenia and osteoporosis, certain cancers, and, perhaps, auto-immune diseases.5

Indeed there are literally hundreds, if not thousands, of well-controlled scientific experiments that show how certain characteristics of the Paleo Diet improve human health.

For instance, just this year, the Journal of Nutrition published a study comparing reduced carbohydrate diets, like the Paleo Diet, to conventional high-carbohydrate diets for weight loss. The reduced carbohydrate diet was more effective in promoting fat mass loss and improved body composition, as well as in reducing serum triacylglycerol and increasing HDL cholesterol.6 While both diets resulted in similar weight loss, more of the reduced carbohydrates diet participants completed the year-long study.6 The researchers also noted that higher protein diets, like the Paleo Diet, appeared to increase satiety7-9 and energy expenditure,10-12 while maintaining lea n tissue with higher metabolic activity.13-15

Furthermore, Paleo-like low salt diets have been shown to improve blood pressure and reduce the risk for stroke and kidney disease.16,17 Low glycemic-load diets, like the Paleo Diet, have improved blood chemistry, insulin sensitivity, diabetic symptoms, obesity, blood pressure, risk of cardiovascular disease, certain cancers16,17 and acne.18 Paleo-like diets high in long-chain omega-3 fatty acids have reduced the risk of heart attacks, stroke, certain cancers, and improved symptoms of many inflammatory and autoimmune diseases.16,17,19 Many chronic diseases are related to low intake of vitamins, minerals and phytochemicals16,17 and the Paleo Diet reduces the risk for these illnesses because it is rich in trace nutrients compared to the typical Western diet.20

Other aspects of Paleo-like diets, such as being high in soluble fiber, potassium, and monounsaturated fats, being very low in industrially-produced trans fats, and yielding a net base load, also have a long trail of scientific support documenting their health benefits.16 These studies represent only an inkling of the dramatic effect we can expect when people get serious about this lifelong way of eating.

Interesting stuff. The only thing worth mentioning here is that a lot of those studies are not unique to the Paleo diet at all but to elements which that (and many other diets) generally encourage. Not knocking on Paleo at all; I'd love to have the discipline to stick with it. That diet destroys me like no other.

Good stuff George. The last line of the study is something that many people will not do though, sadly.

I'm really not sure how the Paleo diet requires discipline. I find it hard to believe that it is really truly that hard to put down the donuts. I could be wrong, and everyone has evolved to eat granulated sugar though in the last 2 years as I stopped doing it. I must be behind on those new fangled diets of eating processed crap.

I have agree with George on this one. It's been about four months since I switch from Zone to a Paleo style diet and adherence hasn't been much of an issue for me. Of course I don't abstain from the homemade birthday cake that comes around the house every couple of months , but I don't crave it every weekend either.

And that is the key Aaron (your nickname should be Duracell lol) ! I'm not one to tell anyone what they can and can't eat, that is a personal decision. Every once in awhile as you describe in my book is perfectly OK. There are too many people in this world though that think an Otis Spunkmeyer muffin is a legitimate food source.

That's not the issue; there is a big divide between eating whole foods, or pretty close, and eating Paleo. I eat a decent amount of stone cut outs and dairy (yogurt and cheese). Also use barley in my chicken soup, tubers (mostly sweet potatoes) with dinner sometimes, and I snack on unsalted peanuts in shell. That's a pretty damn clean diet overall and a farcry from glazed donuts, but also a farcry from Paleo.

Lol, actually it is Double A - Duracell would work too
