15 foods that help to keep you hydrated

Here are 15 different foods that can help keep you hydrated. Some of these you wouldn't have even thought they could have such a high water content, but they do!

According to the old rule you’re supposed to drink eight glasses of water per day and some experts recommend even more.

This can seem like a daunting task on some days, but here’s the catch, you don’t have to drink all that water.

Roughly 20% of our daily H2O intake can come from solid foods, especially when you have your fruits and vegetables.

But it’s still important to drink plenty of water and more importantly in the summertime.

But you can hydrate and quench your thirst with these 15 hugely hydrating foods, all of which are at least 90% water by weight and are listed from the highest through to the lowest.

1. Cucumbers

Cucumbers water content = 96.7%

This hydration super vegetable has the highest water content of any solid food— and is a perfect addition in salads, smoothies or just sliced up and served with some hummus for you to munch on.

If you want to pump up cucumber’s hydrating power even more than it is now, try blending it with non-fat yogurt, mint, and ice cubes to make yourself a cucumber smoothie.

Smoothies are always hydrating and you can throw in a few of the Super Greens Smoothie cubes as well as a good source of other nutrients.

2. Iceberg lettuce

Iceberg lettuce water content = 95.6%

Iceberg lettuce tends to get a bad rap nutrition wise and often it's not justified..

Many nutritionists recommend shunning it in favour of the darker super greens like spinach or kale , which contain higher amounts of fibre and nutrients such as folate and vitamin K.

It’s a different story when it comes to water content though for this lettuce and salad favourite when it comes to helping you stay hydrated.

Crispy iceberg has the highest water content of any lettuce, followed by butterhead, green leaf and the romaine lettuce varieties.

So when the summer temperature rises, pile iceberg onto your sandwiches or use it as a bed for all of your salads.

An even better idea is ditching your bread and using the iceberg lettuce as a wrap for you ingredients.

And of course, if you blend your smoothies you can throw in a few leaves to your favourite summer smoothie recipe and it won't effect the taste too much!

3. Celery

Celery water content = 95.4%

The reports about celery having negative calories when you add it to your daily diet isn’t quite true.

But it’s pretty close.

Like all foods that are high in water, celery has very few calories— coming in at just 6 calories per stalk and it combination of fibre and water helps to fill you up and lower your appetite.

Celery contains folate and also the vitamins A, C, and K and thanks in part to its high water content, celery helps to neutralise stomach acid and is often recommended as a natural remedy for heartburn and also acid reflux.

4. Radishes

Radish water content = 95.3%

These root vegetables should be a fixture in any of your salads and they use to be a lot more popular than they are today.

Radishes can provide a burst of flavour —and colour to any meal and more importantly they’re filled with antioxidants such as catechin which is also found in green tea.

Their crunchy texture also makes radishes the perfect addition to any healthy summer salad or smoothie.

As an easy to make salad you could slice them up with cabbage, carrots, snow peas, hazelnuts and parsley, and then toss with poppy seeds, lemon juice, olive oil, salt and of course pepper.

Finally, if you're going to throw these into your smoothies chop them up finally and make sure the flavour of a radish compliments the other ingredients in your smoothie too.

5. Tomatoes

Tomato water content = 94.5%

Sliced tomatoes can be added to the majority of salads, sauces and sandwiches, but don’t forget about the often overlooked sweet cherry and grape varieties of tomatoes which can make an excellent hydrating snack for you.

If you're having friends over and it's a hot summer day you can skewer grape tomatoes, basil leaves, and add some small blocks of mozzarella on toothpicks for a quick and easy appetiser for them.

Tomatoes are used in small quantities in some smoothie recipes too, or just a plain old homemade tomato juice will do the trick too!

Spinach water content = 91.4% water

Iceberg lettuce may have a higher water content than spinach, but spinach is usually a better bet overall.

Putting spinach (or any leafy greens for that matter) leaves on your salad or as a layer in your sandwich can help provide nearly as much hydration as using iceberg lettuce but it's the greens in the spinach that bring you out on top nutritionally.

Spinach is a nutrient dense super food that may help with eye health, support the reduction of oxidative stress (through its antioxidants), help to reduce blood pressure levels and more.

11. Strawberries

Strawberries water content = 91.0%

All the different berry varieties are good for hydration, but strawberries are easily the best of them all in regards to water and hydration.
