Blast from the Past

The mainstream media is finally catching up to what the research has been telling us for years: saturated fat is not the cause of heart disease. The Wall Street Journal recently wrote an article (that went viral in the ancestral health community) explaining the history of the dietary guidelines recommending avoidance of saturated fat, and why there has never been solid evidence for the idea that these fats cause disease.

While the article has a few flaws, including the suggestion that dietary carbohydrates including starchy vegetables are the root cause of many diseases, the article does a great job of bringing attention to the flaws in the recommendation to replace animal fats with refined vegetable and seed oils. This seems to be a national trend, as even Dr. Oz has recently admitted that he’s been wrong about saturated fat!

I’ve been writing for years about the Diet-Heart Myth. This hypothesis—which holds that eating cholesterol and saturated fat raises cholesterol in our blood—originated with studies in both animals and humans more than half a century ago. However, more recent (and higher quality) evidence doesn’t support it, as this WSJ article points out. For more information about the flaws in this theory, check out my eBook on the topic… and then share it with your doctor!

Research Report

  • An interesting study suggests that people who have a purpose in life have longer lifespans. What is your purpose?
  • Better reported sleep quality (longer duration and better quality sleep) was associated with greater fat loss during a calorie-restriction diet program in adults. So if you’re trying to lose weight, get enough sleep!
  • Further support for the food reward hypothesis: Increasing the variety of flavors in a meal (e.g. adding ketchup to french fries, or adding whipped cream to brownies) led to increased food intake during that meal.
  • This review describes our current knowledge about the gut microbiota and its role in the development of allergic disease.
  • An observational study finds that regular use of calcium supplements is associated with brain lesions in older adults.

Worth a Look

For the Foodies

  1. Would have been helpful if the calcium study had also tracked Vitamin D and Vitamin K2 as well. Could the lesions have come from tissue calcification from not enough of these Vitamins?

  2. Please stop linking to observational studies. They’re good only for forming hypotheses to test in clinical studies and nothing else.

  3. Chris, could you please address the recent articles declaring gluten research by Peter Gibson being false and inaccurate?

  4. So what does a person do when they are allergic to dairy, and are sick of eating kale? I supplement with calcium orotate–the best-absorbed version of calcium.

    • I see from the study that the TYPE of calcium supplements was not mentioned–I bet they were something cheap and not absorbed well, like calcium carbonate. If it was calcium citrate, I bet they weren’t getting enough of it.

      I wonder if the lesions could be associated with not getting ENOUGH of a proper form of calcium. I wish I could just walk in somewhere and be PET-scanned for brain lesions.

  5. The calcium study abstract didn’t make it clear whether foods naturally rich in calcium have the same effect as supplements. I don’t take calcium but I do consume dairy products. Does anyone know what the full study says about that? Or what other studies say?
