Fatty Acids

Fatty Acids

Years of negative associations of dietary fat with calories, cholesterol and even cancer have resulted in the attitude among the general public and many medical professionals that fat should simply be avoided. Yet fatty acids, of which fats are made up of, are critical to normal human function.

Certain key essential fatty acids (EFA’s) are thought to be partially responsible for the development of the human brain in evolutionary terms, and the human capacity for creativity among other things.

EFAs are needed in constant supply and are used to form powerful hormones and cell membranes, and as an efficient source of stored energy. Deficiencies are now prevalent due to modern diets being high in saturated and hydrogenated fats, but low in the many essential fats.

Why test the Omega ratios?

The Omega-6/Omega-3 Ratio:

EFA imbalances have been cited by some experts as the most widespread nutritional problem in modern times. The ratio of omega-6 to omega-3 fats has increased dramatically due to the widespread use of vegetable oils, rising from about 4:1 for Americans at the beginning of the twentieth century to about 20:1 at the present time. Increased consumption of saturated fats and decreased consumption of omega-3 oils (from sources such as cold water fish and flaxseed oil) have also contributed to the growing prevalence of these imbalances. Some individuals with a healthy dietary balance of fatty acids may still have biochemical abnormalities that interfere with their ability to properly metabolise those fats. They may require more targeted supplementation.

At Smart Nutrition we pride ourselves in offering the best cost possible for the fatty acids test.
