"Chicken eggs are high in cholesterol, but the effect of egg consumption on blood cholesterol is minimal when compared with the effect of trans fats and saturated fats." Also egg white is mostly protein and high quality one at that , if you worry about cholesterol just separate the yolk. I eat eggs pretty much daily and have low cholesterol levels. Egg whites are used traditionally by athletes in their diet to maintain a proteic diet so i think the coworker meant well and was on point and the poster is making mountains out of molehills.
