Choose plain yoghurt if you want to add your own fruit or use it in savoury food. Choose Greek yoghurt if you like a thicker texture or want to compare higher-protein options. Check the actual protein per 100 g, since products labelled Greek, Greek-style and regular can differ substantially.
Compare total sugar, ingredients and saturated fat on the same basis. Plain dairy yoghurt can contain naturally occurring milk sugar. If you want to know whether a manufacturer added sugar or syrup, read the ingredients as well as the nutrition panel. Check calcium separately when it matters to you.
- Compare like-sized portions or use the per-100-g column.
- Check protein, sugar, saturated fat and calcium individually.
- Read the ingredient list for sweetened fruit preparations and syrups.
- Buy the container size you can finish within the storage directions.

Compare Greek, Greek-style and regular yoghurt
Traditionally, Greek yoghurt is strained to remove some liquid whey. The result is thicker and often higher in protein per 100 g than regular yoghurt. Manufacturers can use different methods or ingredients to make thick products, so use the nutrition panel to check how much protein your tub actually provides. Harvard Health’s guide to choosing Greek yoghurt
| Product | Why you might buy it | What to check |
|---|---|---|
| Plain regular yoghurt | A spoonable breakfast or simple sauce | Protein, saturated fat and calcium where declared |
| Plain Greek yoghurt | A thicker texture for a bowl or dip | Protein per 100 g and the fat level |
| Greek-style yoghurt | A thick product that may use a different method | Ingredients, protein and total sugar |
| Fruit-flavoured yoghurt | A ready-flavoured snack | Ingredients and total sugar per 100 g |
| Plant-based yoghurt alternative | A dairy-free option where suitable | Protein, calcium fortification and allergens |
A higher-protein product can be useful if that is your priority. A regular plain yoghurt may suit a household that prefers a softer texture or a lower price. Compare nutrition, taste and how much of the product you will use.
Section 2 of 5 · Use both sides of the package
Read sugar, protein and calcium separately
Read the ingredient list for added sweeteners such as sugar, syrup or sweetened fruit preparation. The total sugar figure may include both naturally occurring and added sugars. A plain product can show sugar on the panel because dairy contains lactose. If a manufacturer declares added sugar separately, that figure can help you compare. HealthHub’s guide to reading food labels
Work through a label comparison
Suppose tub A has 9 g of protein and 4 g of total sugar per 100 g. Tub B has 5 g of protein and 10 g of total sugar per 100 g. In a 150 g portion, A supplies 13.5 g of protein and 6 g of total sugar. B supplies 7.5 g of protein and 15 g of total sugar. These figures are invented. The ingredient lists would still be needed to understand what contributes to the difference.
Check calcium when it is the reason you are buying
The protein figure cannot tell you the calcium amount. Compare calcium per 100 g or convert the figures to the same serving. For a dairy-free alternative, check whether calcium is added and how much the product declares.

Section 3 of 5 · Choose a texture you can use twice
Match the yoghurt to what you plan to eat
For breakfast, plain yoghurt with banana and oats gives you room to choose the fruit and portion. For a savoury meal, a thick unsweetened yoghurt works as a dip with cucumber, herbs or lemon. A thinner plain yoghurt can be stirred into a dressing. A fruit-flavoured tub is convenient when the flavour is what you want. Compare the products you are actually deciding between.
If a family shares a large tub, use a clean spoon to serve it and return it promptly to the fridge. If only one person eats yoghurt, a smaller container may be easier to finish. Follow the pack instructions about refrigeration, opening and the date mark.

Section 4 of 5 · Calculate what you expect to use
Compare prices without wasting the last serving
Divide the price by the amount you expect to eat. A 500 g tub costing $5 works out to $1 per 100 g if you finish it. If you use only 300 g, the effective cost is about $1.67 per 100 g eaten. In that case a smaller pack may be better value. Compare the same quantity and include the other ingredients you plan to add.
For a school or work snack, plan refrigeration. A chilled yoghurt pot needs to stay cold until it is eaten. If you cannot maintain that, choose something appropriate for room-temperature storage or buy yoghurt close to the time you will eat it.
After-school snack ideas for different schedules
Decide what a higher-protein tub would replace
A person who usually adds milk to oats may prefer a thick yoghurt that makes breakfast more substantial. A family that wants a dip for dinner may care more about flavour and texture. Compare the cost of the portion you will actually use for that job. If two tubs have similar protein for your portion, compare sugar, saturated fat or calcium according to what matters for the meal. Keep the opened product cold and use the storage instructions rather than guessing how long it will last.

Common yoghurt questions
Does Greek-style yoghurt always have more protein?
Compare the label. Thickness and protein can vary independently across products.
Does plain mean sugar-free?
Plain dairy yoghurt can contain lactose. Read the ingredients if your goal is to avoid added sweeteners.
Can a milk-allergic person eat lactose-free dairy yoghurt?
Lactose-free dairy can still contain milk proteins. Check the allergen label and follow individual care advice.
Is lower fat always the deciding factor?
Choose according to what you are comparing. Saturated fat, protein, total sugar, calcium, price and portion may each matter for different reasons.
