Rick, Will;
Well most of the cholesterol in your blood is self generated in the liver. The brain uses and needs it. The statins that Americans are so fond of are hard on the liver. That is why they want liver efficiency blood tests. Then there are the side effects of the statins.
But back to the subject. There is nothing wrong with Haggis, nor eating liver, kidneys, sweet breads, brains, tongue, tripe, et al. I like them all but they are neigh impossible to find in the US. For years the AMA has looked down on butter, eggs, and lard, but now well, they may not be as bad as oleo, hydrogenated fats, and all the sugars and salt we eat. The more we concentrate on the tree, the less likely we can see the forest. MODERATION is the key.
