Check before you buy

Live and active cultures. Label states live and active cultures; not heat-treated after culturing Products heat-treated after fermentation lose the live bacteria that make yogurt worth choosing over a dessert.
Added sugar. Read added sugars separately from total sugars; plain yogurt has natural lactose but zero added sugar Flavored yogurts vary widely in added sugar, and it is the biggest nutritional difference between brands.
Ingredient list. Plain styles should be milk and cultures only, with no starch, gelatin or pectin Thickeners are used to imitate the body that proper straining or longer culturing gives.
Style vs protein. Strained (Greek, skyr) has roughly double the protein of regular yogurt per serving Pick strained for protein and thickness and regular for smoothies, marinades and a milder texture.
Fat level. Whole milk for texture and satiety; nonfat versions often add thickeners or sweeteners to compensate Fat strongly affects mouthfeel and how full you feel after eating.
