Here’s a very small (14 women), short-duration (2 weeks) study that was funded by several international dairy groups.
Diets With High-Fat Cheese, High-Fat Meat, Or Carbohydrate On Cardiovascular Risk Markers In Overweight Postmenopausal Women: A Randomized Crossover Trial, American Journal of Clinical Nutrition, September 2015
Conclusions: Diets with cheese and meat as primary sources of SFAs [saturated fatty acids] cause higher HDL cholesterol and apo A-I and, therefore, appear to be less atherogenic than is a low-fat, high-carbohydrate diet.

Higher HDL is not always an indication of better health. For instance, in an inflammatory environment (often when someone is overweight), when C-reactive protein (CRP) is high, a higher HDL can increase risk for heart attack:

This dairy study was too small, too short-lived, and lacked the kind of data collection that could help establish cause, that is, whether eating a “high-fat cheese (96-120g)” diet or a “high-fat processed and unprocessed meat” diet protects against the development of atherosclerosis, or, more to the point, protects against a heart attack. It would be telling to follow these women for, say, 10 years on these high-fat cheese diets to see how protective they were.
This seems so unethical to me. It’s tantamount to an advertisement for dairy food, cheese, in the guise of science, in a peer-reviewed study in a professional journal. People will run with this, the media will blow it up, “eat a cup of high-fat cheese every day and” … what, live longer? That’s the implication. That’s not what they found. It’s such a ruse.
The people eating the low fat, high-carb diet weren’t eating a low-fat, high-carb diet. If they were their total cholesterol and LDL would have dropped.

I just stumbled on your website while trying to learn more about the old 1929 African blood pressure study that Greger mentioned.
Great stuff here! I too have come to a plant-based whole food diet after years of study/experiment.
Thank you for your contribution.

Dr. Greger always gives me something to think about. I’m always learning with him.
Thank you for your comments!
