What’s the best way to eat these hydrating foods? Anwers this way...
Cucumber

Technically a fruit (because of the seeds), cucumbers are known for their crunchy texture and delicate, clean flavour. They are rich in antioxidants, contain anti-cancer compounds called cucurbitacins and also plant sterols that help reduce LDL cholesterol.

Cucumbers are the perfect salad ingredient – their subtle flavour pairs well with just about any other vegetable, their texture provides a welcome crunch, and as a low-calorie food they are ideal for light, healthy meals.
Top tip!
Slice up a cucumber, then spread a thin layer of cream cheese and a sprinkle of chopped dill over each piece – voila, a quick and refreshing snack for a hot summer’s day!
Radishes

This pink root vegetable has a peppery kick and contains both immune-boosting Vitamin C and a good amount of fibre, meaning it’s great for your digestive system.

Best way to eat radishes
Whilst radishes are at their most hydrating raw, they are especially delicious roasted – simply chop up and toss in olive oil and herbs before roasting till crispy. They’ll make a nice flavour contrast to a joint of meat.
Top tip!
When making coleslaw, add in grated radishes alongside your shredded cabbage before mixing with the mayo and other ‘wet’ ingredients. It will give the slaw a brighter and tangier flavour.
Celerey

Although most known for their crunchy green stalks, you can also eat celery leaves and seeds – though it is the stalk that contains the most water and what makes it taste so refreshing. Celery also contains vitamins K, A, and C, potassium, and folate.

It’s hard to beat ‘ants on a log’, the healthy snack made by spreading peanut butter into the hollow of a celery stalk and studding it with raisins. Not only is it a medley of flavour, but it’s bursting with protein too.
Top tip!
Take the ants of a log principle and experiment! Stuff the celery hollow with coleslaw, or shredded chicken or hummus.
Allergy alert!
Celery is one of the 14 major food allergens.
Asparagus

A stem vegetable, cultivated for its young, fragrant green shoots, asparagus is low in sodium and fat, and has a high nutrient to calorie ratio, as well as containing vitamins like A, C and K.
Water percentage - 92%

The water content of asparagus is the same whether it’s cooked or raw, and it tastes particularly delicious sauteed with butter in a pan with parmesan cheese sprinkled over the top to caramelise.
Top tip!
The ends of asparagus are tougher and woodier than the rest of the stem and so the overall flavour and texture is improved by removing them.

Whilst an iceberg lettuce leaf it adds amazing crunch to a burger, it’s hard to get much hydration from a single piece. Much better is to braise the lettuce in vegetable stock and a little butter – a moreish side dish!

Stuffed tomatoes are a great dish, but scooping them out removes much of the hydrating fruit flesh. Instead roast them in olive oil with crushed garlic and a sprinkle of rosemary or basil. Then they can be added to salads, sandwiches, omelettes or pasta.
Top tip!
Turn your tomatoes into gazpacho, a cold type of soup. By combining the tomatoes with other watery ingreidents like broth, you’ll have an extra hydrating dish!
