All about Mono-Unsaturated Fats and Poly-Unsaturated Fats

Do you wonder why your olive oil salad dressing gets cloudy inside the refrigerator? And then it gets clear when it is left out? Have you noticed the layer of oil on top of the peanut butter at room temperature?

If your all natural peanut butter has oil floating at the top, do not worry. That is peanut oil. Stir it. Peanut oil is a great example of mono-unsaturated fats. Like olive oil this is an excellent source of these fatty acids.

Mono-Unsaturated Fats

Mono-unsaturated fats contain fatty acids that reduce cholesterol. Usually it is stored in liquid form at room temperature. When it is chilled by refrigeration this healthy fat becomes solid.

You can reduce your cholesterol level in your blood by increasing the good cholesterol (HDL) and lowering the bad cholesterol (LDL). Some people find that mono-unsaturated fatty acids also help reduce triglycerides.

Mono-unsaturated fats are found in many varieties of nuts and seeds. Some excellent sources are: olives, olive and canola oil, peanuts, peanut butter, almonds, pecans, sunflower seeds, or sesame seeds.

Polyunsaturated fats are found mostly in fish, soy, and walnuts. These oils are in liquid form at room temperature and in the refrigerator. This kind of fatty acid helps lower your total blood cholesterol because it decreases the LDL (bad) cholesterol.

Omega three and Omega six are two types of polyunsaturated fatty acids. Omega three fatty acids can reduce triglyceride levels. These fatty acids may each help reduce the risk of stroke, heart attack, and cancer.

Fish is a primary source of polyunsaturated fats. Examples are tuna, trout, herring, salmon, and mackerel. These fatty acids are also in oils such as soybean oil, corn oil, and safflower oil.
