Is juicing or blending better for you?Which? puts nutritional claims to the test

25 June 2016

A woman using a blender in the kitchen.

Is blending the best way to get your five a day, or would you be better off with a juicer?

Don't believe the hype when it comes to blender and juicer health claims. Our exclusive nutritional testing indicates that there's no single type of blender or juicer that consistently extracts the most nutrients from your fruit and veg.

If you're looking to buy a blender or juicer, chances are you'll be confronted by ambitious and competing claims around nutrient extraction, the health benefits of blending vs juicing, and whether different types of juicer are better than others. 

But when we tested the same juice and smoothie recipe in over 20 popular blenders and juicers, we found that different types excelled at extracting different nutrients.

See the full verdict and get advice on choosing the right product for you by heading to our new guides to blenders vs juicers and slow vs fast juicers.

Blender and juicer health claims under the microscope

Expert view, Which? scientist Kishan Chauhan

Neither blending nor juicing gives you the same health benefits as eating a piece of fruit. But they're still a good way of contributing to your five-a-day if you struggle to get lots of fruit and veg into your daily routine.

Blenders are a good source of fibre because they don't remove the pulp from your drink. Our nutritional tests also suggest that blenders retain potassium well, which is good for the heart and kidneys.

Slow juicers appear to rule the roost when it comes to iron and vitamin C. But centrifugal (fast) juicers have the upper hand when it comes to beta-carotene, which converts to vitamin A and helps the immune system.

No single product consistently extracted the maximum amount of each nutrient in our tests, but picking a good or bad juicer or blender will make a difference. The best juicers we've tested extract significantly more juice from the fruit and veg you put in than the worst ones. Choose one of our Best Buy juicers or Best Buy blenders to ensure you get the most from your morning juice or smoothie.

What we did

We tested seven blenders, eight centrifugal (fast) juicers and seven slow juicers. Every machine was tested the same number of times using an identical recipe. We were looking to see how well each model retained key nutrients including fibre, vitamin C, iron, potassium and beta-carotene.

It's easy to fall into the same old routine with your fruit and veg. But blenders and juicers aren't the only products that claim to make it easier to get your five-a-day.

Spiralizers turn your vegetables into long noodle-like strands that can be substituted for carb-heavy spaghetti. We've tried out ten of the most popular models, with some costing less than £20. Find out which one impressed us most by heading to our spiralizer top picks.
