People with diabetes

Watermelon is a fruit that belongs to the group of foods with a high glycemic index (GI), although the glycemic load (GL) is low. Therefore, supplementing this fruit in your daily diet needs to be planned and regularly monitoring blood sugar levels under the guidance of a doctor.

People with cold/flu

Pregnant women

Overall, watermelon is a good fruit for pregnant women, as it contains the antioxidant lycopene and helps reduce the risk of pregnancy complications.

It should be noted that eating too much watermelon can cause a sudden increase in blood sugar levels, which can be dangerous for both the pregnant woman and the fetus. Additionally, if watermelon is left out for too long (more than 2 hours), it can cause food poisoning in pregnant women.

Avoid eating watermelon before or after meals

Many people have the habit of using watermelon as a palate cleanser after meals or sometimes eating it before meals. Both of these ways of eating can affect the digestive system’s ability and function. Specifically, the amount of water in watermelon can dilute the digestive fluids in the stomach, making the process of absorbing nutrients from food slower.

In addition, with this amount of water taking up a considerable volume in the stomach, the body may feel full, reducing the amount of food that can be consumed and affecting overall health.

Avoid eating too much watermelon in a day

As a type of fresh food that can be eaten raw, eating too much watermelon can damage the spleen and cause digestive problems such as bloating, diarrhea, or dilution of stomach fluid.

Avoid eating too much cold watermelon.

Don't eat a lot of frozen watermelon

Many people have a habit of eating cold watermelon as a refreshing treat on hot days. However, this habit should be limited because it can harm the stomach and digestive system, especially for those with toothaches or poor gastrointestinal function.

It is recommended to only eat watermelon that has been stored at a temperature of 8-10 degrees Celsius and consume only about 500 grams per serving.

Do not eat watermelon for too long

Do not eat watermelon that has been cut for too long. Leaving cut watermelon exposed to air for too long creates conditions for bacteria to enter and grow, which can lead to digestive problems. Therefore, it is important to avoid the habit of eating pre-cut watermelon that has been stored in the refrigerator for an extended period.

Do not eat watermelon when feeling tired or fatigued

The white rind of watermelon contains a significant amount of sugar, vitamins, and minerals. It also has the ability to cool down the body, reduce blood pressure, improve immunity and blood circulation. Therefore, you can try eating the white rind instead of peeling and discarding it.

Watermelon seeds can also be eaten

Although it may sound strange and difficult to eat, watermelon seeds contain many beneficial amino acids. These include glutamic acid, which enhances brain function, tryptophan, which promotes good sleep, and lysine, which can help the body absorb calcium and is involved in collagen formation for joints and bones.
