Hemp’s ratio of Omega 6 to Omega 3 fatty acids is about 4:1 which mirrors the primitive diet man evolved on for 2.5 million years. This ratio of fatty acids has been shown to prevent and even reverse Alzheimers disease in animal models and humans (Yehuda et al, Int J Neurosci, vol 3, 141-9, 1996).
The fatty acid gamma-linolenic acid (GLA) is especially beneficial for the elderly who become essential fatty acid deficient as they age. Polyunsaturated fats have been shown to be beneficial for the prevention of heart disease, especially omega 3 fatty acids.
Polyunsaturated fats are good, offering the most double bonds and remain fluid at the lowest temperatures, thereby permitting proper protein (enzyme ) functions necessary for health.
