Strained for protein density, and a genuine gut-health case — if you check the label for live cultures.

Greek yogurt is strained more than regular yogurt, removing much of the liquid whey — the result is a thicker texture and a notably higher protein content per serving than standard yogurt.
Beyond its protein density, plain Greek yogurt with live active cultures provides beneficial bacteria studied for supporting gut microbiome diversity — see our gut health deep dive and fermentation page for the broader research on fermented dairy specifically.
This is one food category where reading the label matters enormously: plain Greek yogurt and flavoured, sweetened Greek yogurt are nutritionally quite different products, with some flavoured varieties carrying as much added sugar as a dessert. Starting with plain and adding your own fruit (like the berries covered elsewhere in this collection) gives you control over both.
Plain, with fresh fruit and a drizzle of honey; as a base for smoothies; or as a substitute for sour cream in savoury dishes — see our overnight oats recipe for one common pairing.
Check the ingredient list for "live and active cultures" — some heavily processed or heat-treated yogurt products lose the live bacteria that make fermented dairy's gut-health case relevant.
