What is watermelon?
Watermelon is a very large vine fruit that grows on the ground. It has a hard, green-striped skin which is inedible. Inside is a soft, bright pink-red flesh with black seeds, both of which can be consumed.
Watermelons are grown in a number of countries, including China, Turkey, Iran, Brazil and the United States.

Top 5 health benefits
1. Supports hydration
Maintaining hydration is essential for health with even modest levels of dehydration likely to manifest as tiredness, headaches, muscle cramps and possible blood pressure problems. Watermelon is largely made up of water (92%), with 20% of our water needs acquired from food, including watermelon can make a useful contribution and especially so for the elderly who are less responsive to the sensation of thirst.
2. May support weight management
Thanks to its high-water content watermelon has a low-calorie density, this means a large slice of watermelon has a relatively small calorie contribution. Eating foods, like this, which are both filling but low in calories appears to help promote fullness and reduce appetite.
3. May support healthy skin and eyes
The pink-red flesh of the watermelon tells us its rich in compounds called carotenoids, including beta-carotene, which we convert to vitamin A. Often called pro-vitamin A, beta-carotene, helps keep our eyes and skin healthy.
4. Rich source of lycopene
Another carotenoid found in watermelon is lycopene, in fact the type of lycopene in watermelon is more readily available to us, making watermelon an especially useful source. Lycopene has received much attention and is believed to be effective in reducing the risk of certain cancers, supporting heart and eye health and reducing the potential of chronic conditions such as type 2 diabetes.
5. May support blood pressure and exercise performance
Is watermelon safe for everyone?
Watermelon is safe for most people to enjoy however there are a small number of people who may be allergic, although this is rare. Allergy may occur as a result of cross reactivity whereby someone allergic to certain pollens, such as the ragweed or grass pollens, may react to watermelon also.
While some allergic reactions can be mild, they can also be life-threatening so if any signs of a severe allergy appear, such as breathing difficulties, trouble swallowing or speaking, or feeling dizzy and faint, emergency medical care should be sought.
