Many people ask what the differences are between the major nutrients, also called "Macro Nutrients." Simply put, there are three Macro Nutrients, and these are most likely familiar to you...they are, Fats, Proteins, and of course, Carbohydrates. So what are the differences? Basically, Fats, also called "Lipids," are oils, and they come in two main flavors, Saturated and Unsaturated. Saturated fats are the 'bad' fats as we all know. So what makes these fats so bad for us? Well, it basically has to do with the chemical structure of the fat molecule and the effects it can have on our cells within our body. Additionally, saturated fats also have been known to aid in the production of LDL (Low Density Lipoprotiein), also known as "bad" cholesterol. These cholsterols are bad because they can contribute to the formation of plaques in our arteries, which can lead to such conditions as CAD (Coronary Artery Disease). Sources of saturated fats include, animal fats, dairy, some nuts, certain fish, and eggs. You can tell a saturated fat from its solid appearance at room temperature. Unsaturated Fats are easy to spot as well. These fats are more 'oily' and tend to be liquid at room temperature. Some good examples include, Olive oil, Safflower, Canola, Borage, and one of the most, unsaturated oils, Flax. These oils aid in production of 'good' cholesterol, also called High-Density Lipoprotein (HDL). HDL cholesterol can help prevent the accumulation of arterial plaques, thus reducing the risk of diseases like CAD.
Fats can also serve as an appetite 'controller' by making us feel full during a meal, and when consumed correctly, can aid in reducing our body fat levels.
