Yoghurt is one of the most versatile, nutritious, and widely used dairy products in the world. Enjoyed for breakfast, used in cooking, blended into sauces, or eaten as a snack, yoghurt has been part of global food cultures for thousands of years. From creamy Greek yoghurt to drinkable varieties and plant-based alternatives, yoghurt offers flavor, texture, and health benefits in equal measure.
This detailed guide covers everything you need to know about yoghurt: how it’s made, different types, nutritional benefits, how to buy and store it, and the best ways to use it in the kitchen.
What Is Yoghurt?
Yoghurt is a fermented dairy product made by adding live bacterial cultures to milk. These cultures—most commonly Lactobacillus and Streptococcus strains—convert lactose (milk sugar) into lactic acid. This process thickens the milk and gives yoghurt its characteristic tangy flavor.
Because of fermentation, yoghurt is often easier to digest than milk and contains beneficial bacteria that support gut health.
Types of Yoghurt Explained
Natural (Plain) Yoghurt
Unsweetened and mildly tangy, natural yoghurt is the most versatile option. It works equally well in sweet and savory dishes, marinades, sauces, and baking.
Greek Yoghurt
Greek yoghurt is strained to remove excess whey, resulting in a thicker, creamier texture and higher protein content. It’s ideal for breakfast bowls, dips, desserts, and as a healthier substitute for cream or sour cream.
Skyr
Originating from Iceland, skyr is technically a fresh cheese but nutritionally similar to yoghurt. It’s very thick, high in protein, and low in fat.
Drinking Yoghurt
Thinner in texture and often flavored, drinking yoghurt is popular as a quick snack or breakfast on the go.
Flavored Yoghurt
Often sweetened and combined with fruit, vanilla, or honey. While tasty, flavored yoghurts can contain high amounts of added sugar.
Plant-Based Yoghurt
Made from soy, coconut, almond, oat, or cashew milk. These are suitable for vegans and people with lactose intolerance, though protein and probiotic content varies by brand.
Health Benefits of Yoghurt
Yoghurt is packed with essential nutrients and offers multiple health benefits:
- Probiotics support digestion and gut health
- High in protein, especially Greek yoghurt
- Rich in calcium for strong bones and teeth
- Contains B vitamins, including B12
- May improve lactose digestion
- Supports immune health
For maximum benefits, choose yoghurts labeled with live and active cultures and minimal added sugar.
How to Choose the Best Yoghurt
When buying yoghurt, check the label carefully:
- Look for live cultures
- Choose plain or low-sugar varieties
- Avoid unnecessary additives and thickeners
- Select full-fat, low-fat, or fat-free based on your dietary needs
Full-fat yoghurt often provides better flavor and satiety, while low-fat versions reduce calorie intake.
How to Store Yoghurt Properly
- Keep refrigerated at all times
- Seal tightly after opening
- Use clean utensils to avoid contamination
- Consume before the expiration date
Once opened, yoghurt is best used within 3–5 days for optimal freshness and flavor.
Cooking and Baking with Yoghurt
Yoghurt is a powerful ingredient in the kitchen:
Savory Uses
- Marinades for chicken, lamb, and vegetables
- Creamy sauces and dressings
- Dips like tzatziki and yoghurt-based spreads
- Soups and stews for added richness
Sweet Uses
- Breakfast bowls with fruit and granola
- Smoothies and shakes
- Cakes, muffins, and pancakes
- Desserts as a lighter cream substitute
Yoghurt adds moisture to baked goods and helps tenderize meat when used in marinades.

Yes—homemade yoghurt is simple and cost-effective. All you need is:
- Milk

- Gentle heat and time
Homemade yoghurt allows full control over thickness, tanginess, and ingredients.

When paired with fruit, nuts, seeds, or whole grains, yoghurt becomes a complete and nourishing meal.
