According to Tro V. Bui, a visiting fellow in animal science at Cornell University, "There is no real difference in nutritional value between brown and white eggs. However brown eggs have more Omega-3 fatty acids but the difference is almost negligible." White eggs are laid by white feathered chickens with white or light colored earlobes while the brown ones are laid by brown feathered chickens with red earlobes.
You would be correct to assume that there are more white eggs in the market than brown ones but that's because breeding and raising white feathered chickens is much cheaper. Since they aren't fed as much as their brown counterparts. Moreover the reason brown eggs cost more is because they come from chickens that have a big appetite. These brown feathered chickens eat more and hence are expensive to keep.
A lot of research has been done to identify the difference between brown and white eggs in terms of nutritional value but so far the majority seems to believe that there isn't any. Dr.Gargi Sharma, weight-management expert believes that brown eggs are healthier than white egg and for those looking to get their fair share of protein and and at the same time wanting to keep in check things like cholesterol and calories, brown eggs are a better option.
