No cheating, kids. Hartwig emphasizes the importance of sticking to this plan with zero slip-ups, so you give your body the complete break (from not-so-healthy food) it deserves. If life happens and a glass of wine or a piece of bread gets in the way, Hartwig recommends starting over. She wants you to feel the full benefits of the entire 30 days. We're not gonna lie: We've let a glass of wine slip before, we didn't start over, and still felt on top of the world at the end. (We aren't suggesting you do the same, but we're just being real with you.) For a full list of rules, visit Whole30.com.
Food and Western Disease: Health and nutrition from an evolutionary perspective by Staffan Lindeberg (MD at Lund University in Sweden) is the newest book promoting the paleo diet. It covers the link between diet and disease in the Western world (all major diseases, including cancer, heart disease, obesity, stroke and dementia) and towards a greater knowledge of what can be defined as the optimal human diet. Benefits and risks are detailed. The Amazon reviews are all 5 stars. Especially read Susan Schenck's detailed review. You can read a preview at Google Books
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.
Evolution of the Human Diet: The Known, the Unknown, and the Unknowable by Peter S. Ungar. Diet is key to understanding the ecology and evolution of our distant ancestors and their kin, the early hominins. A study of the range of foods eaten by our progenitors underscores just how unhealthy many of our diets are today. This volume brings together authorities from disparate fields to offer new insights into the diets of our ancestors. Paleontologists, archaeologists, primatologists, nutritionists and other researchers all contribute pieces to the puzzle. The book has four sections: Reconstructed diets based on hominin fossils--tooth size, shape, structure, wear, and chemistry, mandibular biomechanics. Archaeological evidence of subsistence--stone tools and modified bones. Models of early hominin diets based on the diets of living primates--both human and non-human, paleoecology, and energetics. Nutritional analyses and their implications for evolutionary medicine.
The best part of CFA are the people! CrossFit has really changed my life and my perspective on so much. There are so many things that CrossFit and it’s community of people, especially the women, have taught me. I’ve finally found not only an outlet I was missing since my gymnastics days, but also a group of people who continually inspire me, support me and others, and are genuinely interested in seeing their peers meet goals. CrossFit has completely solidified my viewpoint that people and relationships matter most in life.
The WHO trial (so named because the international team of principal investigators contained World Health Organization members) tested the potential of clofibrate, a “pre-statin” cholesterol-lowering agent, to reduce heart attack morbidity and mortality. The investigators ultimately concluded that clofibrate "cannot be recommended as a lipid-lowering drug for community-wide primary prevention of ischaemic heart disease.” Nevertheless, clofibrate remained in use until 2002, when it was pulled for increasing cancer rates. In their review of studies such as the WHO trial, Uffe Ravnskov and David Diamond observe, “Despite the largely disappointing findings from 50 years of cholesterol lower[ing] trials, the indictment and conviction of cholesterol as the causal agent in CVD [cardiovascular disease] has stood the test of time. … [Yet] the grand effort to reduce cholesterol as a strategy to improve health has failed.”
