"For over thirty years, fat in our diet has been considered the culprit in obesity, heart disease, and high cholesterol. Recent studies dispel these beliefs and show that good fats are absolutely essential to our health and well-being. But which fats are good? Sifting through all the information can leave you with even more questions. Here is a basic primer."

"For most people the word fat is associated with the padding on their bellies and hips used to store excess calories.  But those bulges aren't fat per se ? they?re adipose tissue, which the body uses to store special molecules called fatty acids.  Fatty acids perform a wide variety of functions in the body, functions so vital to our health and well-being that we would instantly fall over and die without them."

"This distinction between adipose tissue and fatty acids (or fats) is important.  To understand the purpose of fats and their value, we must see them as more than just a curse to our waistlines."

"The human body uses fatty acids to do everything from building cell membranes to performing key functions in the brain, eyes, and lungs.  The functions of fats include:"

". The body burns fats for fuel and stores extra fuel in adipose tissue so that it always has reserves to draw from.  Adipose is the most efficient way for the body to store energy.  If the body were to store the same amount of energy in the form of carbohydrates, it would weigh twice as much and take up more space.  Adipose also protects and cushions the organs, and like insulation in a house, keeps us warm. "

"Fats are broken up into three families, and the poly-unsaturated family is further split into two groups: "

"It?s important to note that one family is not more important than another.  The body uses different fats in different places depending on what it needs to do.  For instance, poly-unsaturated fats are typically used by body parts that have the highest activity such as the brain and eyes. Each type of fat is vital to the body. "

"Foods in nature typically contain some combination of all three families of fats, and some foods contain more of one type then another.  For example, avocados contain 28% saturated, 68% mono-unsaturated and 13% poly-unsaturated.  Flax seeds are high in Omega 3 (63%) and sunflower seeds are high in Omega 6 (65%).  Olives and nuts are typically high in the mono-unsaturated fats, and animal fat and coconut oil are high in saturated fats. "

"Polyunsaturated fats are broken up into the Omega 6 family and the Omega 3 family.  Each of these families has a ?parent? fatty acid, also known as the essential fatty acids, or EFAs:"

"Technically, as long as the body has the parent fatty acid, the rest of the family can be made by the body.  However, the body cannot make the parent fatty acids, thus the term, ?essential fatty acids.?  When you hear the word ?essential? in nutrition, it means the body can?t make it on its own and has to get it from an outside source.  "

"The body functions optimally with a 2:1 balance of Omega 6 to Omega 3.  Most Americans, however, are getting a 20:1 ratio. This imbalance is largely due to a high intake of vegetable oils, margarine, and processed foods made with partially hydrogenated soybean oil, all of which are high in Omega 6.  To compensate, it?s important to add foods to your diet that are rich in Omega 3 or to supplement. "

"Although most foods contain a combination of the different types of fatty acids, it is helpful to know which foods are good sources of certain types of fat in order to include them in your diet."

"Fats are good if they come from whole, natural, unprocessed foods.  Fats are only bad if they become damaged. Fats are damaged by heat, light and oxygen. High heat and chemicals used by manufacturers to process oils are the chief sources of damaged fats.  One particularly damaging process is partial hydrogenation, which gives oils longer shelf life. This process creates trans fats and other altered molecules that are harmful to the human body. "

"Poly-unsaturated fats are the most fragile. Oils that are high in poly-unsaturated fats (such as flax seed oil) must be refrigerated and kept in a dark container.  Cooking with these oils damages the fats, depleting their nourishment, and creates oxidized fats and toxins.  Oils that are best for cooking are those high in the mono-unsaturated fats (such as olive oil and macadamia nut oil) or ones that are high in saturated fat (such as coconut oil) because saturated fats are resistant to damage. "

"A trans fat is a normal fat molecule that has been twisted and deformed during the hydrogenation process. Trans fats mimic natural fats in some respects, but are unnatural to the human body. No amount of trans fats is healthy. If the diet does not contain enough good fat, the body will use the deformed trans fats instead.  Studies have implicated trans fats as contributing to major health risks from heart disease to cancer. "

"The FDA now requires food manufacturers to list trans fats on nutrition labels. If the ingredients contain partially hydrogenated oil then the product is suspect, even if the label says no trans fats. To bypass the labeling rules, manufacturers sometimes decrease the serving size until the number of trans fats is less than .5 grams, which regulations permit listing as ?zero? trans fats.    "

"Americans are turning to low-fat and no-fat processed foods in a misguided effort to keep their weight down.  Ironically, these processed foods are one of the main culprits in weight gain because these foods are typically ?high glycemic.?  High glycemic foods cause the level of blood sugar to spike (to rise suddenly). Sustained high blood sugar levels are so destructive that the body attempts to get the sugar out of the blood fast to minimize any damage. One way the body will do that is to signal the liver to take the sugar from the blood and turn it into ?long chain? sticky saturated fat ? the exact kind we are trying to avoid.  The liver will create more fat than the body can immediately use, so the extra fat is stored in the adipose tissue (e.g. on our hips).  Ironically, pulling the good fat out of the food causes the body to build up the kind of fat we?re trying to avoid. "

"Coconuts are 92% saturated fat, which often makes people avoid them.  But all saturated fats are not created equal. 65% of the saturated fats found in coconut are what is called ?medium chain.? Medium chain fats have unique characteristics that set them apart from the other fats.  One is that they do not require bile from the liver for digestion, so they are quickly absorbed and used by the body for quick energy. Medium chain fats also protect the body from disease by disabling and killing bacteria, viruses, and parasites."

"Manufacturers pull out these medium chain fats and sell them as a separate supplement called MCT oil. This oil is good for people with liver/gallbladder issues who need the energy from fat but have trouble digesting it. Athletes also use this oil for quick energy.  "

"Eating good fat causes the body to be satiated quicker and longer than occurs with the consumption of carbohydrates and refined sugars.  Therefore, you will eat less. Good fat, especially in conjunction with fiber and protein in whole foods, will
