Sadly, it’s dangerous to think outside the box. Particularly in the scientific community. If you harbor a view that’s contrary to the whole (even in light of good, sound, scientific evidence), you are demonized, belittled, and shunned.
That’s why when one of the world’s most prominent lipid researchers did an (ahem!) honest review of the observational studies linking dietary intake of saturated fat to heart disease, I take notice. If he can get away with being honest, then surely the tide in scientific thinking must be turning!
Regular readers know that I am a fan of saturated fat, and you often read articles I post in which I challenge the lipid hypothesis — the notion that eating a diet high in saturated fat and cholesterol causes heart disease. New readers come on the site and are shocked that someone like me, someone so in favor of “healthy” eating, could possibly defend diets high in saturated fat and cholesterol.
Well now Dr. Ronald Krauss has published a review article titled “Meta-analysis of prospective cohort studies evaluating the association of saturated fat with cardiovascular disease.”
A meta-analysis of prospective epidemiologic studies showed that there is no significant evidence for concluding that dietary saturated fat is associated with an increased risk of CHD or CVD.
Yay! Chalk one more up for the Truth.
Guys, this is really making me hopeful. The researchers spelling the end of the lipid hypothesis are no longer cutting-edge, but increasingly more mainstream. I hope that in a decade, doctors will look back with horror on the times they advocated cutting saturated fat and cholesterol in the diet. (Much the same way they now balk at blood-letting or smoking cigarettes.)
