Cholesterol does not cause heart disease: Dr Mercola

Cholesterol has been blamed for just about every case of heart disease for the last 20 years, when in reality, you need cholesterol in order to be healthy; your body uses cholesterol for cell membranes, hormones, neurotransmitters and overall nerve function
Your total cholesterol number is not a good indicator of heart disease risk. One of the most important tests you can get to determine your risk is the NMR lipoprofile, which measures your LDL particle number. This test also has other markers that can help determine if you have insulin resistance, which is a primary cause of elevated LDL particle number and increased heart disease risk
Research published over the past 10 or 15 years suggests that neither saturated fat nor high-cholesterol foods will raise your cholesterol serum levels
The primary cause of heart disease is not high cholesterol but insulin and leptin resistance, which increase LDL particle number via a couple of different mechanisms. Poor thyroid function can also directly increase LDL particle number, and should be checked if your LDL particle number is high
Insulin and leptin resistance is caused by factors inherent in our modern lifestyle, including a diet high in processed and refined carbohydrates, sugars/fructose, refined flours, and industrial seed oils; insufficient physical activity; chronic sleep deprivation; environmental toxins; and poor gut health
