Barbara O'Neill: "People with high cholesterol levels don't get Alzheimer's."

"Why don't they get Alzheimer's? Because what does the brain love? Fat."

"They've gotten many people on cholesterol-lowering medication. They've got everyone on the fat-free diet. And because you're not getting the feeling of satiation or satisfaction when you eat, the person eats huge amounts of carbs."

"Surely all of that has reduced heart disease?"

"No, it's still the number one killer."
