Cholesterol is carried through the blood stream by carriers called lipoproteins. There are two types of lipoproteins. They are LDL and HDL.
LDL (low-density lipoprotein) – LDL is referred to as the bad cholesterol. They transport cholesterol to the body cells. High levels of LDL can result in heart attack or stroke.
HDL (high-density lipoprotein) – HDL is referred to as the good cholesterol. They carry the excess cholesterol from the cells to the liver for removal. Adequate levels of HDL reduces the risk of heart attack or stroke.
What is the recommended daily fat intake?
It depends on your body health, amount of physical work you do everyday, age and several other factors. Consult your physician/dietitian regarding this.
What are the types of Fat?
What are trans fats?
- Trans fats are a type of unsaturated fats found naturally in small quantities in some foods. They are manufactured in the industries by adding hydrogen to liquid vegetable oils to make them solid at room temperature. This is mainly done to increase their shelf life. Snacks made with these hydrogenated fats turn out to be crispier.
- Sources : Processed foods, chips, cookies, food with shortening, foods with partially hydrogenated oil.

Simple rules to follow:
