Watermelon is an excellent choice for those who are looking for a refreshing, healthy snack. However, what many people don’t know is that watermelon is very good for regulating your bowel movements!

According to Libby Mills, a spokesperson for the Academy of Nutrition and Dietetics, the high water content of watermelon (approximately 99 percent water) makes it so effective in relieving constipation.

Watermelon contains approximately 0.4 grams of fiber per 100 g serving, which is relatively low but can still add some bulk to your stools to keep things moving along smoothly.

Therefore, regularly consuming water-rich and fiber-rich fruits and vegetables, such as watermelon, can be very helpful for improving regular, painless bowel movements.

Can Watermelon Cause Diarrhea?

Watermelon contains sorbitol which is a sugar compound commonly known to encourage loose stools and gas problems. Watermelon also contains lycopene, which is a pigmented antioxidant that provides watermelon with its bright color.

According to Healthline, watermelon also contains high amounts of fructose, which is a type of FODMAP that some people are unable to fully digest. These can cause many unpleasant digestive symptoms, such as bloating, gas, cramps, diarrhea, and even constipation.

If you suffer from IBS, it is therefore advised to steer clear of watermelons, as they may experience adverse side effects such as the ones mentioned above. However, your average, healthy person should not experience any issues, so long as they are consuming watermelon moderately.

Does Watermelon Make You Poop Red?

While the sight of red poop may be alarming at first, there is a scientific reason behind this, and no, you are not dying!

According to, watermelon may make your poop red due to the fact that the pulp of the watermelon will often pass through the intestines without going through many changes. This may give your stools a reddish, mottled appearance that can appear to look like blood, which is certainly a cause for concern for most.

Red poop due to ingesting watermelon is not really common in adults (unless you eat extremely large quantities of watermelon), but is rather more common in young children and babies as their intestines are immature and will find it more difficult to break down foods.

However, if you do notice red poop and you haven’t eaten anything out of the usual, it is definitely recommended that you consult with your doctor to see if there is anything to worry about.

According to Healthline, vitamin C is a water-soluble nutrient. vitamin C that has not been absorbed creates an osmotic effect in your digestive tract, which means that it draws water into your intestines, which helps to soften your stools.

Watermelon contains approximately 8.1 mg of vitamin C per 100 grams, which means you are getting a healthy dose when you eat 1-4 cups of watermelon.

Potassium is an important electrolyte that works by ensuring the muscles in your body are functioning optimally. This includes the muscles located in your colon! When your potassium levels drop, the muscles in your colon don’t move as much as they should, and this can result in constipation.

Watermelon contains around 112 mg of potassium per 100 grams of watermelon, which is not too bad at all!

Magnesium is often used to treat constipation, as it relaxes the muscles found in the intestines, creating a smoother flow as the stools move through the bowels.

Magnesium also absorbs water into the intestine, so it acts as an osmotic laxative. The extra water stimulates bowel movements and softens and increases the size of the stools, resulting in a smoother bowel movement.

Watermelon contains about 10 mg of magnesium for every 100 grams of watermelon you consume.

It is recommended that you eat no more than 4 cups of watermelon per day, to stick to your RDA and reap the benefits rather than the drawbacks. Sticking to this amount will keep you hydrated, as well as keep your bowel movements regular.

Watermelon contains high amounts of sugar, with around 6 grams per 100 grams, so the same portion of watermelon would leave you consuming around 30 grams of sugar!

Ideally, the average person should be consuming between 100 to 150 grams of sugar daily, from all their food combined. This is why eating watermelon could rack up your count faster than you think!

Excess sugar that cannot be broken down and absorbed by the body is left to ferment in the bowels, causing it to move more slowly through the large intestine, which feeds bad bacteria and yeast and causes a build-up of gas. This in turn causes constipation, cramps, spasms, and pain.

Lycopene is a common nutrient found in watermelon, and too much of this can cause nausea, diarrhea, indigestion, and bloating, according to LiveScience. Consuming more than 30 mg of lycopene per day may result in the above-mentioned side effects.

Best Way To Eat Watermelon

In order to fully take advantage of the benefits of watermelon, it is important that you only eat it once it is fully ripe. The redder it appears, the higher the concentration of lycopene, beta-carotene, and phenolic antioxidants.

Lycopene is linked with heart health, bone health, and prostate cancer prevention, and is also good at decreasing inflammation and improving digestion.

Just remember to stick to your RDA of 30 mg so you don’t experience any negative side effects!
