Questions Q: What exactly are essential fatty acids? Essential fatty acids are vital nutrients critical for health. When a nutrient is classified as essential it means that the body needs it to function properly but the body cannot make it for itself and we must provide for it in the form of food or as supplement. Strictly speaking, there are only two essential fatty acids, alpha-linolenic acid (ALA) from the Omega 3 family and linoleic acid (LA) from the Omega 6 family. Using the ALA and LA our body can make the other fatty acids in the respective Omega 3 and Omega 6 families. However, most people also classify the other fatty acids in the Omega 3 family (eicosapentaenoic acid and docosahexaenoic acid more commonly know as EPA and DHA) and the Omega 6 family (gamma-linolenic acid, arachidonic acid, dihomogamma-linolenic acid) as essential fatty acids as well. Q: Why aren’t people getting essential fatty acids in their food? Most of us just don't eat as healthy as we are told we should, or as well as we think we do. Most people are too busy to plan their meals and will with little hesitation include ‘fat free’, ‘fast food’ and processed foods in their daily diet. Take for example, health organisation guidelines commonly advise people to take at least 5 servings of fruits and vegetables daily and according to a survey done in the USA most people are just not doing that. We believe this situation is universal and not only confined to USA. If we eat healthily to provide the body with the nutrients required to perform optimally, then we would most likely not need to supplement (assuming that the soil is not deficient of nutrients and the fruits are not picked green). So although essential fatty acid can be obtained from many food sources like avocados, ground flax seeds, raw nuts and seeds, dark green vegetables like kale and broccoli, deep water fish, extra virgin olive oil, flax seed oil, and other pure properly processed oils, supplementation still makes good sense especially for those of us who cannot fit three nutritious meals into our hectic lifestyle. Taking supplements is like having a health insurance to ensure that we are getting the essential nutrients we need for the body to perform its work. A deficiency in essential nutrients won’t kill us instantly but it will surely affect our health adversely over time. The body needs the essential fatty acids as raw material to do its work every single day of our lives. When these are missing over a long period of time, we get off balance, our entire body slows down and we will experience ‘dis ease’ eg., tiredness, depression, anxiety, skin problems and many others. These are the very first sign of imbalance. Q: Does everybody need fat? Yes, everybody needs fat. Without the right kind of fat our health will be adversely affected. Fat like carbohydrate and protein are macronutrients that provides the body with energy. We have been taught that we need carbohydrates and protein to maintain health but most of us know very little about fat. We have been conditioned to think that fat is bad and we are all confused and scared of fat. Fat is critical for health and we need to provide our body with sufficient amounts of fat daily because our body needs fat as raw material to function properly. When a nutrient is a macronutrient it means that we need a generous amount daily (ie., in terms of a tablespoonful rather than just a pinch). Infants and children need fats for proper brain and nerve tissue development and for growth. Adolescents and young adults need fats for hormone production and for reproductive maintenance. In women, a shortage of body fat can affect their ability to reproduce. Research shows that anorexics, and other women with minimal reserves of body fat, have rare or non-existent periods. At all ages, fats:
Studies show that our brain has a high percentage of fat, some experts say that our brain is more than 50% fat. Without proper amount of fat our brain will not be able to function optimally. Researchers are finding strong associations between lack of essential fatty acids in our diet and human dysfunctions such as depression, learning disabilities, anxiety, increased blood pressure and much more. We know that not all fat are good for us and we need to learn to differentiate the different types of fat. Q: What’s the difference between the good fat and other types of fat? How can I tell what is good fat and what is bad fat? All fats and oil contain a combination of different fatty acids. The main types of fat are saturated fat, monounsaturated fat, and polyunsaturated fat. There are also trans fats which are important for us to know and avoid. Trans fats are man made fat and they are present in a number of foods and are commonly linked to heart disease. Saturated fats (SFA) are usually solid at room temperature and primarily come from animal foods such as meat, poultry, butter, and whole milk. Coconut and palm oils are also high in saturated fat. Saturated fat is responsible for raising cholesterol levels. Monounsaturated fats (MUFA) are liquid at room temperature. Food sources of monounsaturated fats include olive oil, canola oil, nuts (almonds, cashews, hazelnuts, pistachios, pecans), and avocados. Monounsaturated fats are considered ‘good’ fat because they help decrease the risk of heart disease. Polyunsaturated fats (PUFA) are liquid at room temperature and remain liquid in the refrigerator. Food sources of PUFA include vegetable oils (corn, soybean, sunflower), walnuts, sunflower seeds, sesame seeds, and flaxseed. The Omega 3 and Omega 6 fatty acids come from this group but not all PUFA are essential fatty acids. Trans fats (TFA) are man-made or processed fats which are made from a liquid oil. When we add hydrogen to liquid vegetable oil and then add pressure to it we get a fat that is more solid at room temperature. This process is known as hydrogenation. Trans fats are also called hydrogenated fats. Trans fats can be found in cookies, crackers, icing, potato chips, margarine, microwave popcorn and in almost all processed foods. Hydrogenated vegetable oils are more stable and give processed foods a longer shelf life and help keep crackers, biscuits and chips crisp longer. Numerous studies have found that trans fats raise our risk of heart disease and they can also contribute to an increase in total cholesterol levels and a drop in the healthy HDL cholesterol. These man-made fats are much worse for you than the natural saturated fats found in butter and meat sources. Avoid these at all costs!. We should all aim to:
Q: How do we know if we are deficient in essential fatty acids? What are the EFA Deficiency Symptoms? The symptoms of essential fatty acid deficiency are not easy to identify, and can often be attributed to some other health conditions or nutrient deficiencies. Most people who are deficient in essential fatty acids don’t even realize that they are not consuming enough of the essential fatty acids. When in doubt always check with your health care professionals. There is equipment available that can test the nutrient level in your body. Symptoms of Omega 3 deficiency include:
Q: Where can we find food sources of Omega 3 and Omega 6?
Food sources of Omega 6 include:
Whether we get the essential fatty acids from the food we eat or
through supplements, the important thing is that we get the
essential fatty acids into our body for it to do its work and
for us to live a healthier life. Please remember that our body
needs both the Omega 3 and the Omega 6 fatty acids and we cannot
just substitute Omega 3 for Omega 6 or Omega 6 for Omega 3. |
