Some foods are marketed as healthy but contain more added sugar, salt or processing than you might expect. You don’t need to avoid them completely, but it helps to know what to look for on the label.

Here are ten “healthy” foods worth a second look.

1. Fruit juice

Juice contains vitamins, but it lacks the fibre of whole fruit and can be high in natural sugars. A small glass is fine; whole fruit is more filling.

2. Fat-free and low-fat packaged foods

When fat is removed, sugar or other ingredients are sometimes added to improve taste. Check the label.

3. Flavoured yogurt

Many flavoured yogurts contain lots of added sugar. Plain yogurt with fresh fruit is a simple alternative.

4. Granola

Granola can be high in sugar and oil. Look for lower-sugar versions, or make your own.

5. Protein bars

Some protein bars are closer to sweets than to a balanced snack. A handful of nuts or a piece of fruit with yogurt can be just as satisfying.

6. Bottled smoothies

Smoothies can be a nice treat, but shop-bought ones are often high in sugar. Homemade versions with vegetables and whole fruit keep more fibre.

7. Gluten-free snacks

If you need to avoid gluten, these are a helpful option. Otherwise, gluten-free doesn’t automatically mean healthier, and some versions are highly processed.

8. Veggie crisps

They sound healthy, but many are fried and salted like ordinary crisps.

9. Diet fizzy drinks

They’re sugar-free, but research on artificial sweeteners is mixed. Water, tea and sparkling water with fruit are refreshing alternatives.

10. Sweetened plant milks

Plant milks can be a great choice, but some contain added sugar. Look for unsweetened versions, ideally with added calcium.

Read labels, not slogans

Words like “natural”, “light” and “healthy” on packaging don’t always tell the full story. A quick look at the ingredients and the sugar and salt content can help you choose.

If you already follow a special eating plan, keep to it and let these ideas fit around it.
