There are very different kinds of animal fat, e.g. cod liver oil has very different properties from butter or lard or bone marrow. Small amounts of animal fat are unlikely to cause any health problems, but great quantities can be harmful. As an anecdotal experience, a few years ago I have been diagnosed with an incipient atherosclerosis, which has scared me a lot. Analyzing what might have caused it, I assumed that it could have been the great amount of dairy that I was eating at that time, i.e. the high daily intake of saturated fat. I have completely changed my diet, with the essential difference being the fatty acid profile of the food. After some experiments I have settled on a diet where more than 90% of my daily fat intake was provided by a mixture of oils added to food (50 mL of extra-virgin olive oil for oleic acid, 20 mL of cold-pressed sunflower oil for linoleic acid and vitamin E, 10 mL of cod liver oil for DHA and EPA and vitamin A and a drop of an oil with vitamins D3 and K2). After about a year since the change of diet the symptoms of atherosclerosis have disappeared together with some other older problems caused by a poor peripheral circulation. From this I have concluded that my guess about my high consumption of dairy (i.e. of saturated fat) being the culprit for my cardiovascular health problems had been correct.
