What’s the difference between regular, Greek and skyr yogurt?

All yogurts start the same way. Bacterial cultures are added to milk, creating yogurt’s tangy flavour and thick texture. The difference comes after fermentation.

Regular yogurt is not strained, giving it a thinner texture and slightly higher calcium content.

Greek yogurt is strained to remove some of the liquid whey, creating a thicker yogurt with more protein and less sugar than regular yogurt.

Skyr is an Icelandic-style yogurt, typically made from fat-free milk. It’s also strained, high in protein, low in fat and milder in flavour than Greek yogurt.

Because Greek yogurt and skyr are strained, they contain less lactose, which may make them easier to tolerate for some people with lactose sensitivity.

If you avoid dairy, there are many plant-based yogurt alternatives including those made from soy, coconut, cashew, almond and hemp. Soy yogurt is the closest nutritional match to dairy yogurt because it naturally provides protein. Look for options with protein, lower in added sugars and fortified with calcium and vitamin D.

Easy ways to use yogurt in the kitchen

Both regular and Greek yogurt are nutritious and versatile ingredients. Greek yogurt’s thicker texture makes it ideal for dips and sauces such as tzatziki. Plain yogurt can also replace mayonnaise, sour cream and buttermilk in many recipes. Add yogurt to smoothies, salad dressings and baked goods for extra creaminess, moisture and protein. For a simple breakfast or snack, top plain yogurt with fruit, high-fibre cereal and nuts or seeds.
