Experts estimate that our ancestors consumed a one-to-one ratio of calories from meats to produce. Since you have to eat a lot of salad to consume the same amount of calories in a steak, the paleo diet should ideally include mostly fruits and vegetables, Katz says. However, many people don't realize that and eat too much meat. Consuming excess protein and not enough carbs can cause kidney damage and also increase your risk of osteoporosis, Dr. Ochner says. Plus, since most of today's meats are higher in saturated fat than those of yesteryear, it can increase the risk of heart disease, Dr. Katz says.
To determine the diet rankings, US News & World Report selected a 25-person expert panel from the country's top dietitians, dietary consultants, and physicians specializing in diabetes, heart health, and weight loss. The panel included Lisa Sasson, MS, RDN, CDN, a clinical assistant professor and dietetic internship director in the department of nutrition and food studies at New York University; Jill Weisenberger, MS, RDN, CDE, CHWC, FAND, a nutrition and diabetes expert; and David L. Katz, MD, MPH, FACPM, FACP, FACLM, founding director of Yale University's Yale-Griffin Prevention Research Center, and founder of the True Health Initiative.4
Take 30 days and give it a shot – cut out the grains and dairy, start eating more vegetables and fruits, eat more humanely raised and non-grain fed meat, cut out the liquid calories and sugar, and see how you feel after the month is up. If you’re analytical and want numbers to use in your final verdict, get your blood work done at the beginning and end of the month.
Fresh fruits, fresh vegetables, fresh meat—the paleo diet is all about eating foods straight from the Earth just as our ancestors did. Those ancestors didn't have livestock or crops to call their own, so Cordain advises to go with grass-fed and organic varieties whenever possible to limit exposure to pesticides, antibiotics, and other chemicals that didn't exist back then. Research from Emory University suggests that Paleolithic people obtained about 35% of their calories from fats, 35% from carbohydrates, and 30% from protein.
The NY Times had a blog article on Good News on Saturated Fat which is reporting on Gary Taubes's interpretation of the new report in The New England Journal of Medicine on a two-year diet experiment in Israel. A followup is the post The Fat Fight Goes On where Gary rebuts the arguments against the study. And here's a good interview with Taubes (and includes a good summary): Gary Taubes on Cold Fusion, Good Nutrition and What Makes Bad (and Good) Science.
We also believe there are benefits in putting an extra emphasis on organ meats, bone broths, Antarctic krill oil supplementation (due to very high EPA and DHA demands on fetal brain development —potentially draining mom’s stores) and 100% organic/fully pastured/wild caught sources of meats, seafood, eggs vegetables and greens. As mother’s milk is an extremely critical source of medium chain triglycerides meant for the rapid growth of the baby’s brain and nervous system, we believe using a little more coconut oil in the diet could be helpful, too. Quality has never mattered as much as it does during this time. Also, in our opinion there has never been a more important and utterly critical time to avoid highly antigenic foods such as gluten, grains and dairy products (except for possibly camel’s milk, which is expensive and a bit hard to come by, but is generally safe from an immune reactive standpoint. It’s nearly identical in its total composition to human milk, and as such may prove useful where supplementing regular breast-feeding might be necessary, as well as a non-immune reactive dairy alternative).
Physicians, biochemists, nutritionists, and other researchers are starting to come around to the benefits of ancestral nutrition, and people who adopt a Paleo-like approach to eating are reporting significant improvements in their general health, body composition, and energy levels. Most importantly, there’s evidence that folks who eat this way are reducing their risks of numerous diseases and disorders that are associated with the Standard American Diet (S.A.D.).
Want to make your mornings a whole lot easier? Of course you do. Well, a batch of easy egg muffins is the answer. Loaded with savory breakfast sausage, earthy mushrooms, and spinach, these make-ahead muffins are for people who love eggs and crave a satisfying breakfast that will get them through the morning. They're also great for anyone in need of a one-handed morning meal they can eat on the go, or dig into when they get to their desk.
Healthy, delicious, and simple, the Paleo Diet is the diet we were designed to eat. If you want to lose weight-up to 75 pounds in six months-or if you want to attain optimal health, The Paleo Diet will work wonders. Dr. Loren Cordain demonstrates how, by eating your fill of satisfying and delicious lean meats and fish, fresh fruits, snacks, and non-starchy vegetables, you can lose weight and prevent and treat heart disease, cancer, osteoporosis, metabolic syndrome, and many other illnesses.
Grass-fed beef is often highlighted on the diet, which is promoted to contain more omega-3 fats than conventional beef (due to being fed grass instead of grain). It does contain small amounts of alpha-linolenic acid (ALA), a precursor to EPA and DHA. However, only a small proportion of ALA can be converted in the body to long-chain omega-3 fatty acids (EPA and DHA). The amount of omega-3 is also highly variable depending on the exact feeding regimen and differences in fat metabolism among cattle breeds.  In general, the amount of omega-3 in grass-fed beef is much lower than that in oily marine fish.  Cooked salmon contains 1000-2000 mg of EPA/DHA per 3-ounce portion, whereas 3 ounces of grass-fed beef contains about 20-200 mg of ALA.
Saturated fat has been demonized by our health authorities and media. What is the basis for this position on Saturated fat? Are current recommendations for VERY low saturated fat intake justified? How much saturated fat (and what types), if any should one eat? Without a historical and scientific perspective these questions can be nearly impossible to answer.
