Here are 9 things you need to know when eating watermelon:
Do not eat bananas with watermelon
According to Nguyen Tri Phuong Hospital (HCMC), watermelon contains about 15% sugar and is rich in potassium. Meanwhile, bananas are also rich in potassium, about 300-500mg/100g. Therefore, patients with kidney failure should not eat two fruits with high potassium content such as bananas and watermelon at the same time.
If the potassium content in the blood increases, it can cause heart rhythm disturbances, seriously affecting the patient's health.

Do not eat watermelon before and after meals.
Watermelon is a fruit with a lot of water. If you eat it before or after meals, it will dilute the digestive juices in the stomach, affecting the ability to digest and absorb food. In addition, when you take in a large amount of water, it will make you feel full, reduce your appetite, and affect your health.
Therefore, people who want to lose weight can eat a moderate amount of watermelon right before meals to limit the amount of food intake.
Don't eat too much
As a cold food, you should not eat too much because it will cause diarrhea, bloating, loss of appetite... In addition, 94% of watermelon is water, with such a large amount of water it will dilute gastric juice, cause indigestion and affect digestive function.
Don't eat too much cold watermelon.
In the summer, this fruit is always the top choice to quench thirst. However, eating a lot of cold watermelon will have a significant impact on the stomach. It is best to ensure the temperature to keep the watermelon fresh, not too cold.
You can put the whole watermelon in the bottom compartment of the refrigerator, keep it at 8-10 degrees Celsius. This temperature ensures the watermelon is fresh and delicious while preserving its flavor. You should not eat more than 500g at a time, eating slowly is best.
Don't eat watermelon that has been cut open for too long.
In the summer, high temperatures cause bacteria to thrive. If watermelon is cut open and left at room temperature for too long, bacteria will invade it and when eaten, it can cause digestive problems such as diarrhea.
People with kidney failure should not eat
Weak kidneys reduce the function of excreting water, so patients with kidney disease often have swollen feet.
Eating too much watermelon will cause water retention, the kidneys will not be able to excrete water from the body in time, leading to the amount of water exceeding the body's water storage capacity, increasing blood volume. The swelling will become more and more serious, leading to fatigue and exhaustion.
Therefore, people with weak kidneys or kidney disease should eat less or not eat watermelon to ensure health.
Diabetics should limit their intake of watermelon.
Watermelon contains glucose, sucrose and fructose, so when you eat watermelon, your blood sugar level increases.
For normal people, the body will secrete insulin to help maintain stable blood sugar levels and urine. But for diabetics, it is completely the opposite, eating a lot of watermelon causes blood sugar levels to increase, disrupting the body's metabolism, leading to poisoning, even endangering life.
Pregnant women
Eating too much watermelon during pregnancy will cause high blood sugar levels. During pregnancy, women's psychology is unstable, physiology also has many changes, the amount of insulin secreted is not enough, causing the effect of blood sugar to decrease, high blood sugar levels, causing gestational diabetes.
In addition, eating cold watermelon can easily cause stomachache and diarrhea in pregnant women. Therefore, pregnant women should not eat too much, especially not eat cold watermelon, no matter how hot the summer day is.
