Watermelon intake: When this summer delight could do harm

In the summer, many people eagerly reach for watermelons on hot days. These juicy fruits undoubtedly quench thirst effectively, and because they are made up of 90% water, they are an ideal choice for supporting the body's hydration. This fruit is also rich in immune-boosting vitamin C. On the other hand, due to vitamin A, watermelon has a good effect on the skin and eyes, and the magnesium and potassium it contains help properly function the muscular and nervous systems.

It is worth noting that not everyone can enjoy its taste without consequences, and some should exercise caution and avoid consuming watermelons. This includes those allergic to watermelons and those struggling with various ailments.

Diabetics should consume watermelons in moderation. Although their glycemic index (GI) is low, their glycemic load, which takes into account both the GI and the amount of carbohydrates in a serving, is high. Therefore, they can be part of a balanced diet that takes total carbohydrate intake into account in meal planning. Without this, they can lead to a dangerous spike in blood sugar levels in the course of diabetes.

Similarly, those with fructose intolerance who have trouble digesting this sugar should limit their intake of large amounts of watermelon. Otherwise, they may have to deal with bothersome gastrointestinal symptoms like stomach pain, bloating, nausea, or diarrhea.

Although watermelon, which is 90% water, hydrates well, those suffering from kidney diseases should be cautious. This is due to the potassium found in these fruits, which diseased kidneys cannot effectively eliminate from the body. An excess of potassium can lead to hyperkalemia and, consequently, even to cardiac arrest.

Importantly, watermelons are rich in lycopene, a powerful antioxidant. However, it is essential to be aware that it can interact with alcohol, significantly burdening the liver. Therefore, people who abuse alcohol should also be careful with watermelons.
