What is Cholesterol?
Unsaturated fat: fat or fatty acid in which there is at least one double bond within the fatty acid chain.
Saturated fat: Fat that consists of triglycerides containing only saturated fatty acid radicals
Trans fat: the common name for unsaturated fat with trans-isomer fatty acid
Cholesterol: A compound of the sterol type, found in most body tissues and important in metabolism
All these things go together because they affect the cholesterol blood level. Unsaturated fat reduce cholesterol levels, while saturated fat decreases insulin sensitivity and causes the body to store food as more fat, rather than use it for something else.
