Vitamin D is the one supplement that would be paleo. At least it would be for those of us that don't live outside year round. You can have your D level measured. The low RDAs only prevent definable deficiences, not problems that take a long time to develop. Michael Holick, MD is a leading writer on this subject. This is a 10 page PDF: Vitamin D: importance in the prevention of cancers, type 1 diabetes, heart disease, and osteoporosis and its companion Sunlight and vitamin D for bone health and prevention of autoimmune diseases, cancers, and cardiovascular disease [change PDF to 100% to read]. Or if you prefer, there is an hour video on YouTube.
Trying to devise an ideal diet by studying contemporary hunter-gatherers is difficult because of the great disparities that exist; for example, the animal-derived calorie percentage ranges from 25% for the Gwi people of southern Africa to 99% for the Alaskan Nunamiut. Descendants of populations with different diets have different genetic adaptations to those diets, such as the ability to digest sugars from starchy foods. Modern hunter-gatherers tend to exercise considerably more than modern office workers, protecting them from heart disease and diabetes, though highly processed modern foods also contribute to diabetes when those populations move into cities.
Note: If you don’t have a grill, you can bake the chicken in the oven. Turn the oven to Broil (or 500°F), and place the raw chicken in a baking dish. Sear the chicken in the oven for 5 minutes. Reduce the oven temperature to 350°F. Brush the chicken with the curry sauce and finish cooking in the oven for 10 to 15 minutes (depending on thickness), until the internal temperature reaches 160°F.
Still, many scientists have expressed concern that we do not yet have enough evidence to make any strong claims about the paleo diet’s health benefits, especially its long-term effects. In fact, in an article in response to the first review, authors Tanis R. Fenton and Carol J. Fenton, from the Cumming School of Medicine in Canada, wrote a letter to the editor in which they expressed their disappointment with the review. (5)
"Loren Cordain's extensive research demonstrates how modern westernized diets drastically depart from the original diet humans consumed for millions of years. In The Paleo Diet and The Paleo Diet Cookbook, Dr. Cordain shows how diets high in grains, dairy, vegetable oils, salt, and refined sugars are at odds with our genetic legacy and then shares his uncomplicated strategy for losing weight and getting healthy."
This is a list of paleo diet meats allowed on the diet. Almost all meats are paleo by definition. Of course, you’ll want to stay away from highly processed meats and meats that are very high in fat (stuff like spam, hot dogs, and other low-quality meats), but if it used to moo, oink, or make some other sound, it’s almost certainly paleo (and, yes, that means you can still have bacon). Here’s the full list of paleo diet meats.
Smoothies are generally discouraged on Whole30. However, if you must have one, choose a recipe with no added sweeteners and low-sugar fruits. This smoothie is more scoopable with a spoon, so you can slow down and savor it (important on Whole30!). The only sweet flavor comes from fresh raspberries — plus, this packs your bowl with fats from avocado and coconut milk.
The Paleo diet has been associated with many health benefits from better blood sugar levels to reduced inflammation. Considered one of the best diet plans for weight loss because it’s high in protein and fat and emphasizes nutrient-rich foods, it may also increase satiety and help correct nutrient deficiencies. Still, the diet has remained the subject of much controversy in recent years.
Eat WELL Feel GOOD: Practical Paleo Living by Diane Frampton has over 200 recipes that makes paleo eating simple, delicious, and ultimately, intuitive. So they claim. There are only a few reviews at Amazon. They all like the book, but their lack of details makes it appear that they are not truly independent reviews. The recipes have a Crossfit appeal to them. Chef Rachel Albert has made some of the recipes and posted here [archive.org].
I experienced some funky physical symptoms during the first 10 days or so, but this is pretty typical of a Whole30. I would feel great, and then the next day I would feel tired, achy, and bloated. Depending on what your diet was like before you started the Whole30, you’re bound to get hit by some sort of detoxing symptoms. If you’re doing this after eating a lot of sugar and processed food, your symptoms might be a bit more severe. However, the book assures you it’s normal, and it will even out. According to the authors, the bacteria in your gut are shifting and creating a new landscape. Your body is getting used to this new diet of protein and a ton of veggies with the absence of sugar. Things adjust and shift. For me, this meant a couple days of feeling off.
A study published in the Journal of Strength and Conditioning Research entitled "Crossfit-based high intensity power training improves maximal aerobic fitness and body composition" followed 54 participants for 10 weeks of CrossFit training. The study said that "...a notable percentage of our subjects (16%) did not complete the training program and return for follow-up testing." The authors said "This may call into question the risk-benefit ratio for such extreme training programs..." In 2014, CrossFit, Inc. filed a lawsuit against the National Strength and Conditioning Association for publishing this study, alleging that the data were false and were "intended to scare participants away from CrossFit." The NSCA denies CrossFit, Inc.'s allegations but has issued an erratum acknowledging that the injury data were incorrect. In September 2016, the District Court ruled in favor of CrossFit Inc.'s claims that the injury data were found to be false, but not that the NSCA was commercially motivated or that the publishing of the study was defamatory as the NSCA no longer stood behind the study. In February 2017, CrossFit filed for sanctions against the NSCA after one of the NSCA's witnesses admitted to falsifying statements during deposition. In May 2017, the Court issued 17 issues sanctions against the NSCA, writing that the organization did have a commercial motive to falsify the data, had published the false data knowingly to disparage CrossFit, and had misled the public with their erratum. CrossFit was awarded $74,000 in legal fees and allowed to continue investigating the NSCA. If the neutral-party analysis of the NSCA servers turns up any further misconduct, CrossFit may file an amended complaint for further sanctioning and compensation for lost revenue.
The Paleolithic Prescription: A Program of Diet & Exercise and a Design for Living by S. Boyd Eaton, M.D., Marjorie Shostak and Melvin Konner. This book, published in 1988, was the start of the Paleolithic diet movement. Its recommendations are not in line with what today is considered a paleo diet, as whole grain breads and pastas, legumes and some low fat dairy products are allowed. However, it is still a profoundly important book. Used books are available for a reasonable price.
