ABSTRACTAs natural eggs can contribute significantly to overcoming dietary deficits, we have designed and studied the composition of multiple-enriched eggs (Benefic(R) eggs) whose composition is close to the natural egg. They are obtained by feeding laying hens in the usual way, but using additional autoclaved linseed, minerals, vitamins and lutein to provide the extra components. These eggs have greater nutritional value than standard. Thus 100 g of these eggs contains 6 times more of the omega-3 fatty acid ALA (15% of the French recommended daily allowance (RDA)), 3 times more DHA (100% of RDA), 3 times more vitamin D (30% of RDA), 4 times more folic acid (70% of RDA), 6 times more vitamin E (66% of RDA), 6 times more lutein and zeaxanthine (70% of international recommendation), 2.5 times more iodine (100% RDA), and 4 times more selenium (45% RDA). As the content of omega-6 fatty acids remains unchanged, the omega-6/omega-3 ratio is lower, and thus improved. These eggs contain a little less cholesterol and, like standard eggs, are rich in vitamin B12 (160% of RDA) and vitamin A (25% of RDA), plus vitamin B2 (riboflavin), vitamin B5 (pantothenic acid) and phosphorus. Proteins quality is indeed excellent. These eggs are interesting for everybody, and particularly appropriate for older people. The nutritional value of enriched eggs (similar to the multiple-enriched eggs of this study) has been assessed in animals and in human volunteers in terms of their influence on blood lipids. They improve the blood concentration of omega-3 fatty acids, HDL cholesterol, LDL cholesterol and triglycerides.EFAs
