One Major Side Effect of Only Eating Egg Whites, Says Science

Remember when everyone went through that phase of being hesitant to eat foods with naturally occurring fat? Eating egg whites and ditching egg yolks was just one component of food that was shamed into oblivion. Full-fat yogurt and cow's milk also got pushed to the sidelines in favor of low-fat and fat-free options.

Thankfully, society has grown since that moment, with many health experts now encouraging people to consume foods that are rich in healthy fats, as that usually also means they're rich in various nutrients. These foods include salmon, nuts, avocado, and yes, even egg yolk. All of these selections, plus many more, can also help keep you stay full and may even make you less likely to consume empty calories later in the day.
