Wheat germ oil

From Wikipedia, the free encyclopedia

Wheat germ oil is extracted from the germ of the wheat kernel, which makes up only 2.5% by weight of the kernel[1] Wheat germ oil is particularly high in octacosanol - a 28-carbon long-chain saturated primary alcohol found in a number of different vegetable waxes.[2] Octacosanol has been studied as an exercise- and physical performance-enhancing agent. Very long chain fatty alcohols obtained from plant waxes and beeswax have been reported to lower plasma cholesterol in humans.[3] Wheat germ oil is also very high in vitamin E (255 mg/100g), and has the highest content of vitamin E of any food that has not undergone prior preparation or vitamin fortification.[4] As a cooking oil, wheat germ oil is strongly flavored, expensive and easily perishable.[1] Wheat germ oil contains the following fatty acids:[5][6]

Component g/100g
Linoleic acid (omega-6) 55
Palmitic acid 16
Oleic acid 14
Linolenic acid (omega-3) 7

Other uses of wheat germ oil have also been explored, including increasing blood flow and reaction time.[7]
