When to avoid watermelon: Health risks and benefits explored

Watermelon can be eaten frequently during the summer. It fits well in savory salads, such as those with feta cheese, and can be made into lemonade, added to desserts, or simply eaten as a snack. However, it's better not to overdo it, and sometimes, you should even avoid it.

Watermelon is associated with summer and hot days. Many people consume it without restraint, unaware of the potential health consequences. However, for certain ailments, consuming can lead to unpleasant effects. Primarily, individuals with kidney failure should limit its intake due to its high potassium content. In extreme cases, it is recommended to eliminate watermelon from the diet, especially if someone is allergic to it (which is very rare).

Watermelon can be problematic for those on a FODMAP elimination diet due to its fructose content. There is also a common belief that watermelon has high sugar levels, which may raise concerns for diabetics. In reality, however, people with diabetes can safely consume watermelon, provided it is done in moderation, as it contains relatively little sugar—about 7 grams per 3.5 ounces of the product.

Watermelons are rich in lycopene, a phytochemical naturally found in vegetables and fruits. Lycopene is known for its antibacterial, antifungal, and antiviral properties. Lycopene gives watermelons, tomatoes, and red grapefruits their characteristic red color. One and a half cups of watermelon can provide about 9-13 milligrams of lycopene, 40% more than in raw tomatoes.

Eating watermelon is beneficial for hydration. Its juice is rich in electrolytes and can reduce muscle soreness and heart rate before intense training. Research published in 2015 in the "Journal of Applied Physiology" showed that citrulline from watermelon could significantly improve athletic performance. Those taking citrulline supplements noticed increased performance and greater energy production during high-intensity exercises, such as cycling or sprinting.
