Designer eggs are those whose composition has been deliberately modified to enhance their nutritional value beyond that of regular eggs. This is achieved by altering the diet or managing the immune systems of laying hens, resulting in eggs free from harmful components and enriched with beneficial nutrients. Designer eggs offer various health advantages, such as lower cholesterol, higher levels of unsaturated fatty acids, and an optimal omega-6 to omega-3 ratio, which contribute to cardiovascular health. These eggs are particularly valued for their enhanced nutritional profile, including increased antioxidants like vitamin E and carotenoids, as well as higher levels of n-3 fatty acids like Docosahexaenoic acid (DHA). These improvements not only enhance the eggs' stability during storage and cooking but also ensure the availability of essential nutrients without compromising taste. Consuming designer eggs can significantly boost up the antioxidant and n-3 fatty acid status of individuals, making them a valuable addition to a healthy diet. According to relevant scientific research and reviews, "designer eggs" represent a promising development in the functional food industry, paving the way for set up a new era of healthfocused food products that cater to the evolving needs of consumers.
