For many different reasons, I like Greek yogurt. It’s a great source of protein, first and foremost, and I often choose full-fat Greek yogurt over low-fat or fat-free varieties to receive all those good fats.

Probiotics, also known as beneficial bacteria, are abundant in them and are crucial for a strong immune system and healthy gut.
