UK Oat Milk Brands Ranked By Sugar Content

Is sugar content everything? 

No! Sugar is just one element of the nutritional profile and isn’t the be all and end all.

Other macronutrients like protein, fibre and fat play an equally important role in your health.

How to find the sugar content of oat milk? 

Aside from using the list above, simply check the nutritional label (rear of packaging).

Look for “of which sugars” and you’ll see the sugar content per 100ml of oat milk.

As this figure is per 100ml, you’ll need to adjust the value based on your serving size.

E.g. if you have 200ml on your cereal, simply multiply this number by 2. 

Is sugar good or bad?

Pros of sugar

✅ Sugar gives oat milk a sweeter taste, the more sugar the sweeter the taste. 

✅ Sugar is a quick release energy source.

Cons of sugar

❌ The drawback of quick release energy is a sugar crash.

❌ Too much sugar can cause unwanted weight gain from calories. 

❌ Too much sugar can cause teeth decay.

It’s all about moderation and luckily the sugar content of oat milk is relatively low.

For comparison, fizzy drinks contain 3x the sugar, without any of the nutritional benefits. 

How can you minimise the negatives of sugar?

The presence of dietary fibre and fats in oat milk help slow the absorption of sugar into your body.

Slower absorption is beneficial as it prevents sugar crashes and keeps you feeling fuller for longer.
