Abstract From the Canadian patent

Chickens are fed a composition including fish oil over a period of time. Modified eggs laid by such chickens contain substantial quantities of omega-3 polyunsaturated fatty acids. The modified eggs are fed to humans with the result that serum cholesterol, serum triglycerides and blood pressure are reduced as compared to humans eating a like number of regular eggs with a subsequent decrease in heart disease.
