Fat is probably the most maligned, misjudged, and misunderstood of all the macronutrients. In truth, the body needs healthy fats, called essential fatty acids, in very small amounts to maintain many life-sustaining physiological functions. Good fats are the building blocks for hormones and cell membranes, and are responsible for healthy nerve conduction.  Essential fatty acids eaten in small amounts help us to control our weight by slowing down and regulating the rate at which sugar (glucose) enters the blood stream. This controlled release of glucose enhances good blood sugar control.

Essential fatty acids are commonly found in fish, seeds, nuts, and plants. Olive oil, canola oil, flaxseed oil, almonds, and avocados are examples of healthy sources of fats. Omega-3 oils from fish (salmon and sardines) or fish oil supplements are also healthy essential fats. Be aware, however, that there are fats that are potentially harmful to the body. Some margarines and other hydrogenated oils are potentially harmful, for example, because they are trans-fatty acids.  Fats that have been artificially altered to preserve their shelf life-a process that is harmful to your cells may be Trans-Fatty Acids. Trans-fatty acids resemble essential fatty acids, making it difficult for cell membranes to distinguish between the two kinds of fat. However, when trans-fatty acids do enter a cell, they cannot perform the normal functions that essential fatty acids do. They trick your body and do damage because the body doesn't know how to distinguish between the good and the bad, thus opening the door for significant health problems.

Saturated fats are also potentially harmful to the body. For the most part, they are found in animal proteins such as red meats and dairy products.  Saturated fats should be eaten less frequently than essential fatty acids. Trans-fats should be altogether avoided whenever possible. READ YOUR FOOD LABELS!!  Foods that are high in fats, "mono-and polyunsaturated", but low in 'saturated fat', are generally GOOD foods that should be eaten in moderate amounts.
