Vassillissk's answer is incorrect. Animal fats are bad anyway - this is a scientific consensus.
His response said that the idea of dietary cholesterol as a cause of high blood cholesterol was refuted. This is mistake. He does not provide sources, but most likely it is an epidemiological study without preliminary measurements of the initial blood cholesterol level in the participants. The point is, since the starting cholesterol level is different for each person due to genetic differences, you cannot find correlations between cholesterol intake and blood cholesterol levels in humans if you simply take a time slice. What is needed is a clinical trial where people measure their initial cholesterol levels and then change their dietary cholesterol and see how much that changes their blood counts. And such studies have been carried out several hundred, maybe thousands. And the result? Cholesterol in the diet raises blood cholesterol. This leads to the development of atherosclerosis - the number one cause of death in the Russian Federation and in the world.
Of course, everyone chooses their own risk by changing the consumption of animal products, but a well-planned vegan diet is a tool to reduce the risk of atherosclerosis to zero. Moreover, research by Dr. Esselstyn and Dr. Dean Ornish has shown that a good plant-based diet can even cure atherosclerosis! Before that, it was considered impossible. (And even now very few people know about this.)
Recently, the scientific community officially recognized that cholesterol consumption does not increase the amount of bad cholesterol in the blood, but rather lowers it. In this connection, all treatment for high cholesterol has gone to waste.
In fact, the first denials of the harm of high cholesterol consumption were back in the days of the USSR, but until now it was considered absurd. And only about six months ago, they officially denied the harm of cholesterol.
