As promised, in today's article I'll be focusing on dairy fat. Full-fat dairy has been on the shit-list now for several decades because of its high saturated fat content; 2/3 of its fatty acid profile is saturated. Since the creation of the very
first dietary recommendations set forth by the U.S. government, we've been told to avoid anything high in saturated fat because it will clog our arteries and kill us. (In case you missed it,
your arteries will be fine.) Well, people have listened: we now consume approximately 1/3 the whole milk we did in 1970, and our butter has largely been replaced with margarine (see below). We clearly consume far less dairy fat today than we have in the past, but that's not a good thing. Not only does the research show no connection between dairy fat consumption and chronic disease, but grass-fed dairy fat appears to be highly beneficial, and may even actively prevent arterial plaque buildup. Welcome to the fascinating world of dairy fat... it's time to embrace whole milk and butter once again.
Let's open it up with a meta-analysis. This one, done by Dr. Ness and colleagues in the UK, examined 10 cohort studies in which the consumption of milk, or the intake of calcium from dairy sources, has been related to cardiovascular disease (
1). Their conclusion? "Cohort studies provide no convincing evidence that milk is harmful. While there still could be residual confounding from unidentified factors, the studies, taken together, suggest that milk drinking may be associated with a small but worthwhile reduction in heart disease and stroke risk." So the people who drank the most milk experienced reductions in heart disease and stroke risk. Sounds great, but with a reduction in cardiovascular risk like that, they must have been drinking low-fat and skim milk right? No sir/ma'am. As the researchers state in the conclusion of the article, because all of the reviewed studies were set up at times when low-fat milk was unavailable, "it would seem reasonable to assume that the risk estimates obtained relate largely to the consumption of whole milk." BOOM! Whole milk associated with a consistent reduction in cardiovascular disease?? You don't say...
But that's not it... here's another one showing dairy fat prevents cardiovascular disease (
2); this one says dairy fat promotes healthy LDL and HDL levels (
3); this one says dairy fat reduces your risk for diabetes, keeps you lean, and lowers your triglycerides (
4); and this one shows butter is wayyy better than margarine (
5), even though the researchers wouldn't quite admit it (
6). Blah blah blah etc etc etc, the bottom line is that these benefits are the result of dairy
fat. Not fat-free dairy. Not even low-fat dairy.
Full-fat dairy. Whole milk, real cheese, full-fat yogurt, and butter. Dairy fat is good for you. It is
not the devil we're led to believe it is. But there's still more to the story... because there's something even better than dairy fat out there. Meet grass-fed dairy...
