Linolenic acid is a type of fatty acid which is found in vegetable oils. Monounsaturated fats are fat molecules that have one unsaturated carbon bond in the molecule. Olive oil contains monounsaturated fats which are really beneficial to our heart when they are used to replace saturated fat. The low-density lipoprotein (LDL) cholesterol level is low in those people who regularly eat nuts. LDL cholesterol is known as the “bad” cholesterol as it causes plaque, a thick, hard deposit that clogs arteries and makes them less flexible.

The habit of eating nuts enhances the level of HDL cholesterol which is known as good cholesterol as it helps to remove LDL cholesterol from the arteries. A healthy level of HDL cholesterol lowers the chance of heart attack and stroke while high level of LDL cholesterol increases the risk of heart attack and stroke. The presence of heart healthy substances in nuts makes it really beneficial to our heart.

Plaque development in our arteries causes chest pain and heart attack. Vitamin E helps to prevent the development of plaques.

Unsaturated fats:

An unsaturated fat is a fatty acid in which there is at least one double bond with in the fatty acid chain which is monounsaturated and polyunsaturated. Monounsaturated fats and polyunsaturated fats contain fat molecules that have one unsaturated carbon bond in the molecule. Olive oil contains monounsaturated fats and polyunsaturated fats which are really beneficial to our heart when they are used to replace saturated fat. Monounsaturated fats and polyunsaturated fats lower bad cholesterol levels in our blood that can reduce the risk of heart disease and stroke.

L- arginine:

L- arginine is an amino acid, a chemical building block which is immensely important for our body to make proteins. It is found in poultry, fish, red meat and dairy products. High blood pressure, which is also known as hypertension creates microscopic tears in the artery walls that turn into scar tissue and speeds up the hardening process of arteries.
