From left: Supergreens immunity shake, bulk up berry blast, mango energy explosion

If MF had a pound for every time we heard the excuse “healthy eating is too expensive”, well, we could definitely afford to buy a load of overpriced fancy “health” food. But the thing is, improving your diet doesn’t have to cost the earth – in fact, you can even save yourself money. The key is to pick versatile, economical ingredients that’ll last, like the frozen fruit and veg in the recipes here, which actually offer higher nutrient levels than their fresh counterparts (they’re locked in during the freezing process). Simply whack the ingredients in a blender and enjoy a delicious drink without having to shell out £2 for an Innocent.
