Eggs, and especially eggs’ yolks (the yellow stuff), are full with immunity-boosting nutrients. Eggs contain a high amount of vitamin D, which is vital in regulating and strengthening our immunity system. According to a study published by JAMA journal, participants who took a daily serving of vitamin D in the wintertime were less likely to catch a cold or any other upper respiratory tract infection in comparison to those who did not take it.
Eggs also contain protein in the highest quality available. It’s also great for your diet as it is low on fat and calories (70 calories per egg). By the way, an eggs’ shell color has nothing to do with it’s nutritional qualities.
