Which Yoghurts Are Actually Worth Buying? A Health Coach's Guide

The yoghurt aisle has become one of the most confusing places in the supermarket.

Rows and rows of pots all claiming to be healthy: high in protein, low in fat, low in sugar, packed with probiotics, "nourishing," "naturally sweetened." It's hard to know what any of it actually means, let alone which ones are genuinely good for you.

And it matters more than you might think. Yoghurt is one of those foods many of us eat daily, often as a quick breakfast or snack, so the one you choose can either support your energy and protein intake or quietly work against it.

Here's what to look for, what to avoid, and why some yoghurts are so much better for you than others.

Why Not All Yoghurts Are Equal

All yoghurts start with milk and live bacterial cultures, but that's often where the similarity ends.

The differences come down to three main things:

·       How the yoghurt is made (which affects protein content and texture)

·       What's added to it (sugar, sweeteners, flavourings, thickeners)

·       Whether the fat has been removed or kept in (which affects how filling and satisfying it is)

Once you understand these three things, the yoghurt aisle suddenly makes a lot more sense.

Why Some Yoghurts Have More Protein

Protein is one of the main reasons yoghurt is often recommended as a healthy choice. It helps keep you fuller for longer, supports stable energy, and contributes to muscle health. All things that matter if you're trying to feel better day to day.

But the protein content varies enormously between yoghurts, and the reason comes down to how they're made.

Greek Yoghurt and Greek-Style Yoghurt

Authentic Greek yoghurt (look for "strained" on the label) is made by straining natural yoghurt to remove the liquid whey. This leaves behind a thicker, creamier yoghurt with roughly double the protein of regular yoghurt, typically around 9-10g of protein per 100g.

Greek-style yoghurt, on the other hand, is a bit of a marketing term. It's often thickened artificially with cream or starches rather than strained, so it may look similar but doesn't always have the same protein content. Always check the label.

Skyr

Skyr is an Icelandic dairy product (technically closer to a strained soft cheese than a yoghurt) that's been made for centuries. Like Greek yoghurt, it's strained to remove the whey, which gives it a thick, creamy texture and a high protein content of around 10-11g per 100g, very similar to Greek yoghurt. It tends to be lower in fat too, which suits some people but can make it less filling than full-fat options.

Natural Yoghurt

Natural yoghurt is the unflavoured, unsweetened version you'll find in most supermarkets. It's not strained, so the protein content is lower, typically around 4-5g per 100g. It's still a good choice, particularly if you prefer a thinner texture or find Greek yoghurt too rich, but it won't keep you as full for as long.

Kefir

Kefir is a fermented milk drink that's similar to yoghurt but slightly thinner in texture. You'll often find it in the yoghurt aisle (brands like The Collective sit right alongside the regular yoghurts), and it also comes in pourable bottles in the chiller section.

What makes kefir special is that it's made with a much wider variety of bacterial and yeast cultures than standard yoghurt, which means it can offer broader support for your gut bacteria. This matters because gut health plays a key role in digestion, immunity, and even mood.

One of my favourite ways to use kefir is to stir a spoonful into plain Greek yoghurt. You get the protein and creamy texture of the Greek yoghurt, with the wider range of beneficial bacteria from the kefir. A simple way to get the best of both.

As with all yoghurts, look for plain, unsweetened versions where possible. Added sugars can work against the beneficial bacteria you're trying to support.

A Quick Word on "High-Protein" Yoghurts

You'll also see a growing range of branded high-protein yoghurts on the shelves. These are pots advertising 15-20g of protein, often in flavours like vanilla, strawberry, or chocolate.

While the protein content sounds appealing, many of these are highly processed and contain a long list of added sweeteners (often artificial), thickeners, flavourings, and preservatives. The protein figure on the front of the pack can distract from what's actually in the ingredients list.

If your goal is genuinely supporting your health, you're almost always better off reaching for plain Greek yoghurt and adding your own toppings. You'll get excellent protein, a much shorter ingredients list, and none of the additives.

Why Some Yoghurts Are Packed With Sugar

This is where the yoghurt aisle gets sneaky.

Many yoghurts that look healthy on the front of the pack are surprisingly high in sugar once you turn them over. A small fruit-flavoured yoghurt can contain as much sugar as a chocolate biscuit, sometimes more.

There are a few reasons this happens:

1. Flavoured yoghurts almost always have added sugar. Strawberry, vanilla, honey, toffee, lemon. Even ones that sound "natural" usually have sugar, fruit syrups, or concentrated fruit juices added to them. A typical fruit yoghurt contains around 12-15g of sugar per small pot, much of which is added rather than natural.

2. "Low-fat" often means "high-sugar." When fat is removed from yoghurt, it loses flavour and texture. To compensate, manufacturers often add sugar, sweeteners, or thickeners to make it palatable. This is why a low-fat fruit yoghurt can sometimes contain more sugar than a full-fat natural one.

3. Children's yoghurts are often the worst offenders. Pots aimed at children (Petit Filous, Frubes, and similar) frequently contain 8-10g of sugar in a tiny pot, despite being marketed as healthy.

4. Even "natural" yoghurts can contain added sugar. Some brands add small amounts of sugar even to yoghurts that look plain. Always check the ingredients list. If sugar, glucose, fructose, syrup, or concentrated fruit juice appears, it's been sweetened.

How to Read a Yoghurt Label in 10 Seconds

If you only remember one thing from this blog, let it be this: check the label, not the front of the pack.

Here's a simple way to assess any yoghurt quickly:

·       Protein: aim for at least 5g per 100g, ideally higher

·       Sugar: aim for under 5g per 100g (anything above 10g is high)

·       Ingredients list: the shorter, the better. Ideally just milk and live cultures

A genuinely good yoghurt has a very short ingredients list. If you see a long list of sweeteners, thickeners, stabilisers, or flavourings, it's worth putting it back.

Which Yoghurts to Choose

Based on everything above, here's a simple guide to what to reach for:

Best Everyday Choices

·       Full-fat Greek yoghurt (strained): high in protein, naturally creamy, and very filling. This is the one I most often recommend

·       Full-fat natural yoghurt: simple, unsweetened, and a great option if you find Greek yoghurt too rich

·       Skyr: similar protein content to Greek yoghurt, lower in fat, with a milder taste

·       Plain kefir: great for gut health, and can be stirred into Greek yoghurt for added benefits

What to Be More Careful With

• Flavoured yoghurts: most contain added sugar

• Low-fat yoghurts: often higher in sugar than full-fat versions

• Children's yoghurt pots: usually very sugary despite the marketing

• "Greek-style" yoghurts: not the same as real Greek yoghurt, so check the label

• Branded "high-protein" yoghurts: the protein figures can be impressive, but many contain

• artificial sweeteners, thickeners, and preservatives. Plain Greek yoghurt with your own toppings is almost always a better choice

How to Make a Plain Yoghurt Taste Great

One of the biggest reasons people choose flavoured yoghurts is simply because plain ones taste a bit dull on their own. The good news is that it's incredibly easy to make a natural or Greek yoghurt feel like a treat, without affecting your blood sugar:

·       Fresh or frozen berries (lower in sugar than most fruits and packed with antioxidants)

·       A spoonful of homemade compote (gently cook berries or chopped fruit in a pan with a splash of water until soft, no sugar needed)

·       Chopped nuts or seeds for crunch and healthy fats

·       Cinnamon, vanilla extract, or cocoa powder for natural flavour

·       A spoonful of nut butter

·       Chia seeds or ground flaxseed

·       Unsweetened coconut flakes

·       A small amount of homemade granola (check the sugar content of shop-bought varieties carefully)

·       Grated apple or pear with a sprinkle of cinnamon

This way, you get the protein and simplicity of a plain yoghurt, with the flavour and satisfaction of something that actually feels indulgent, without the blood sugar spike that comes from added sweeteners.

The Bottom Line

The best yoghurts are usually the simplest: full-fat, plain, and minimally processed, with a short ingredients list and a decent amount of protein.

Plain Greek yoghurt is the one I most often recommend to clients. It's high in protein, naturally creamy, doesn't need additives to taste good, and pairs beautifully with toppings you actually choose yourself. Skyr and natural full-fat yoghurts are also excellent choices.

Compared to flavoured, low-fat, or "high-protein" branded options, these whole-food yoghurts will keep you fuller, support more stable energy, and won't come loaded with hidden sugars or additives.

A small shift in what you reach for in the yoghurt aisle can make a real difference. Not just to your breakfast, but to how you feel through the rest of the day.
