According to Ray D. Strand, a specialist in nutritional and preventive medicine, not all fats are bad. In fact an essential fat is just that - essential to the body. The body cannot manufacture these fats and therefore must get them from food. The body uses fats for the production of healthy cell membranes as well as certain hormones called prostaglandins. The two most important essential fatty acids are omega - 3 fatty acids, called alpha-linoleic acid, and omega-6 fatty acids, called just linoleic acid. Our bodies turn omega-3 fatty acids into prostaglandins that are primarily anti-inflammatories. Omega-6 fatty acids become prostaglandins that are primarily inflammatories. The generally accepted optimal ratio of dietary intake of omega-6 fatty acids and omega-3 fatty acids is 4:1. The imbalance in the consumption of these essential fatty acids is the main reason for the imbalance in our body’s production of these hormones. That is why many individuals in the industrialised world need to take flaxseed oil and fish oil in supplementation in an attempt to bring these back into balance.
