Welcome to the Illiana Watermelon Association

“Our growers just plain know how to grow watermelon”.

Maybe, it’s because of our rich sandy soil.  It could be our mild summer climate.  Possibly, it is because our harvest comes during the longest days of the summer (Ole Sol kisses our melons longer than any other temperate zone).

The truth is, we believe all of these contribute to making our watermelon, the most mouthwatering and sweetest watermelon in the world.

We invite you to browse our web pages and discover the tender loving care we put into each watermelon we grow and just how much fun we have promoting our delicious juicy fruit.

Powerful Antioxidants

Powerful Antioxidants

This wonderful summertime treat comes packed with powerful Antioxidants along with several vitamins our bodies need. Watermelon is high in Vitamin C and a good source of Vitamin A through its concentration of beta-carotene.

Lycopene

Lycopene

Watermelon is a concentrated source of lycopene, a carotenoid studied for its antioxidant and cancer-preventing properties. It has shown protective effects against prostate, breast, endometrial, lung, and colorectal cancers, and contains more lycopene than any other produce.

Vitamin C

Vitamin C

Watermelon is an excellent source of Vitamin C so necessary for the body’s immune system. Just one cup of delicious watermelon provides 25% of our body’s daily requirement.

Vitamin A

Vitamin A

Through its concentration of beta-carotene, Watermelon supplies a rich source of Vitamin A, another cancer fighting anti-oxidant along with Lycopene and Vitamin C. A cup of Watermelon supplies your body with over 10% of its daily requirement.

Vitamin B

Vitamin B

Vitamin B is necessary for energy production. Watermelon is rich in Vitamin B6 and B1, as well as magnesium and potassium. Because Watermelon has a higher water content and lower calorie content than other fruits, it delivers more nutrients per calorie.

Arginine

Arginine

Watermelon is exceptionally high in citrulline, an amino acid the body converts into arginine. Arginine plays a role in the urea cycle to remove ammonia and supports the production of nitric oxide, which relaxes blood vessels and helps lower blood pressure.
