Our top 20 best low-carb vegetables

Watching your carb intake? While vegetables are packed with vitamins and minerals, their carb levels vary greatly. Check out our favourite low-carb veggies, plus tasty ways to eat them.

If there’s one thing a lot of us could probably use more of in our diet, it’s vegetables. They’re bursting with vitamins, minerals, antioxidants and fibre. But each vegetable is different, and that means very different levels of carbohydrates. For example, a sweet potato contains 21.3g of carbs per serving, while broccoli contains 3.2g. 

When reducing anything in your diet, it's important to make sure you're not missing out on any vital nutrients. As such, if you're conscious of carbs in your diet, consider trying some of these low-carb vegetables listed below.

Carb levels are based on net carbohydrate value of raw food per serving.
