Watermelon is a low-calorie fruit that is high in water and carbs.

It contains essential vitamins and minerals like vitamin C, vitamin A, potassium, and vitamin B5.

Watermelon also has citrulline and lycopene, which have health benefits such as lowering blood pressure and reducing muscle soreness.

However, watermelon is high in FODMAPs, which may cause digestive problems in some people.

One cup of diced watermelon provides 46 calories, 0.9g of protein, 11.5g of carbohydrates, and 0.2g of fat. [1][2][3]
