Udo Erasmus, Ph.D., introduced the importance of essential fats (EFA's) derived from organic flax seeds to the world. He pioneered methods for producing unrefined oils made with health in mind which are still used today by manufacturers of flax and other oils. Starting in the mid-1980's, Udo popularised the use of flax oil through an endless number of public lectures, which eventually led to TV and radio interviews. His groundbreaking book, Fats that Heal Fats That Kill, became the industry's bible on fats. Later he developed an oil blend which is an improvement on flax oil, offering a better ratio of Omega-3 to Omega-6. This oil blend contains everything we need from fats and nothing we should avoid.
