  • CONCLUSIONS: The results of this large observational study indicate a strong inverse association between levels of pre-diagnostic 25-(OH)D concentration and risk of colorectal cancer in western European populations. Further randomised trials are needed to assess whether increases in circulating 25-(OH)D concentration can effectively decrease the risk of colorectal cancer

  • until I read Good Calories, Bad Calories (GCBC) by Gary Taubes I still thought that food was just fuel and obesity was always due to bad genes, or overeating, or lack of exercise - the usual suspects
  • Some diseases that are very common today, which we call Diseases of Civilization or DOCs, do not occur with any frequency in native or hunter-gatherer populations until western foods are introduced
  • The background assumption was that cancer, heart disease and obesity are only issues because we live long enough to get them now, and aren’t we lucky for modern medicine?
  • ...20 more annotations...
  • There was really no print equivalent to today’s 24/7 propaganda of pop nutrition via MSN and Yahoo, with perky titles about the latest worthless observational study associating a colorful plant with some tertiary biomarker of health status
  • But in Gary’s book, the descriptions of populations that ate native whole-foods diets, and what happened to them when they started to eat the white man’s food, was totally eye opening and had never been hinted at in my medical school curriculum
  • You all know this one - The vegan menace. Killing infants and robbing adults of their vitality is the ultimate denial of biology. Endorsed by countless brainless celebrities
  • It seemed that the only commonly agreed-upon element among those claiming to invoke what we are “evolved” to eat, might be that cereal grains should not be a predominant part of the diet
  • That we are eating some things we are clearly inadequately adapted to seems certain, but the idea that the dietary bright line is narrow and exists at the 10,000 year mark is a cartoon view not supported by the science
  • In biology, “putative” means an agent that we think is the responsible or active agent, but we are always trying to falsify our hypothesis. We are always looking for evidence that we might be wrong about our agent.
  • The problem in wheat is proteins, not carbohydrate. White flour is dense and highly concentrated in these problematic proteins and antinutrients. Wheat causes problems even in those who’ve been eating it for thousands of years
  • Eat potatoes, sweet potatoes or root veggies for your starch, and stop eating all bread, cookies cakes and other baked goods
  • Fructose is a carbohydrate, but metabolically it is quite different from the glucose that comes from starch
  • the actual requirement is so small it might be better considered a micronutrient
  • As n-3 and n-6 precursors compete for the same enzyme in the eicosanoid pathway, the excess of n-6 in the diet means that n-3 is outcompeted at the enzyme level. The result is a preponderance of inflammatory molecules. Increased cancer and inflammation are both likely related to this
  • Many are aware that 6:3 ratio is important, so they try to compensate by taking fish oil to balance the 6:3 ratio
  • High total PUFA, especially including the highly unstable n-3, leads to oxidative damage to your cells. Your arteries, liver and  other organs don't appreciate extra oxidative damage
  • Stop eating all temperate vegetable oils – cooking and frying oils like corn, soy, canola, flax, all of it. And go easy on the nuts and factory chicken
  • a substantial fraction of nutrition from animal sources is necessary for health
  • Reject the alternative hypothesis of saturated fat or cholesterol as a Neolithic agent – the so-called diet/heart hypothesis
  • Discount the absolute importance of macronutrient ratios in the nutritional transition
  • whole foods diet that includes adequate micronutrients is the best way to eat healthy
  • tubers, root vegetables and other sources of starch can be healthy for normal people
  • A diet that is archaic, in the sense of appealing to the past with both science and history, but not intending to re-enact a battle that has only happened in our imaginations
