Interesting discussion on google plus which started with this post https://plus.google.com/u/0/109926473783208635050/posts/8cZfL4Xn77F :

""" There are a lot of people online these days who claim saturated fats aren't bad for your heart, despite the mainstream medical recommendations to reduce saturated fats in your diet.

The evidence they point to is usually pretty sparse or logically/scientifically unsound. My worry is that many people will follow this advice, thinking it's sound, and end up with higher rates of heart disease.

This systematic review is the best I've seen on the topic, and it's by the gold-standard of systematic reviews (Cochrane Collaboration):


I'd recommend a thorough read of it, as it gives a great review of the background of this issue and the most important studies on the topic.

Some points to note:

  1. The Siri- Tarino meta study that many saturated-fat advocates point to is included in the review. The problem with this study is that it is an observational study, not based on intervention trials, and so the scale of measurement error is such that detecting the effects of dietary factors on cardiovascular risks are dif???cult.

  2. The evidence isn't conclusive yet, but the best analysis of what we have so far indicates that replacing saturated fats with unsaturated fats reduces the risk of heart disease.

  3. Replacing saturated fats with carbohydrates (low-fat diets) is inconclusive so far.

  4. There is no good evidence to indicate that eating lots of saturated fats is healthy for your heart, regardless of the source of those saturated fats."""

I think the discussion is interesting but the guy is a vegan, so I question his motives (and possibly integrity on this issue). http://zenhabits.net/my-story/
