Watermelon is considered a summertime staple, popping up at pool parties and summer barbecues all season long. While it’s well-known for its ability to keep you cool and hydrated, there are tons of other health perks associated with this popular fruit that are not as well-known.

What are the benefits of eating watermelon? As you’ll learn more about below, this fruit is low in calories, a good source of vitamins C and A, and has been linked to everything from reduced muscle pain and enhanced exercise recovery to improved vision and skin health.

Nutrition Facts

The watermelon plant, also known by its scientific name Citrullus lanatus, is a member of the flowering plant family known as Cucurbitaceae.

Is watermelon a fruit?

Yes, the spiky, low-to-the-ground watermelon plant, which originates from southern Africa, produces the popular edible fruit we now commonly consume.

It’s believed that wild varieties that were grown many years ago were more bitter than the types we eat today, thanks to the presence of a compound called cucurbitacin. Historically, many varieties, with different colors and tastes, were grown in various parts of the world, including across Africa.

Believe it or not, it’s estimated that there are actually more than 1,200 different cultivars of watermelon still in existence. This includes the lanatus, crimson sweet and jubilee watermelons.

Unbeknownst to most people, the entire watermelon is edible, including the rind and seeds. In fact, watermelon rind (which can be pickled or even stir-fried) is very high in citrulline, a compound that’s transformed into the amino acid arginine, which is associated with cardiovascular benefits and more.

The seeds are also chock-full of amino acids, the “building blocks of protein,” as well as some trace minerals, which is why they are included in some plant protein powders.

Is watermelon a “superfood”?

While it may not be as nutrient-dense as fruits such as berries or oranges, there are still some impressive benefits associated with watermelon nutrition.

All varieties are loaded with antioxidants and have been associated with a wide range of health benefits — such as better heart health, enhanced immunity and increased weight loss.

Two especially protective compounds found in this fruit are citrulline and lycopene.

According to the U.S. Department of Agriculture’s data on watermelon nutrition, one cup (about 152 grams) contains approximately:

  • 46 calories

  • 11.5 grams carbs

  • 1 gram protein

  • 0.2 grams fat

  • 0.6 grams dietary fiber

  • 12.3 milligrams vitamin C (21 percent DV)

  • 865 international units vitamin A (17 percent DV)

  • 170 milligrams potassium (5 percent DV)

  • 15.2 milligrams magnesium (4 percent DV)

  • 0.1 milligrams thiamine (3 percent DV)

  • 0.1 milligrams vitamin B6 (3 percent DV)

  • 0.3 milligrams pantothenic acid (3 percent DV)

  • 0.1 milligrams copper (3 percent DV)

  • 0.1 milligrams manganese (3 percent DV)

Top 12 Benefits of Watermelon

Here are some of the top benefits of watermelon:

1. Can Help Support Immunity

In animal studies, watermelon consumption has been linked to reduced inflammation and improved antioxidant capacity.

Lycopene, one of the carotenoids found in abundance in this fruit, has potent antioxidant properties and can help reduce oxidative stress. It may also help keep your heart healthy, as well as defend against certain types of cancers, cardiovascular disorders, diabetes and macular diseases, according to recent research.

Studies show eating it can also increase levels of arginine, an important amino acid that’s used for the synthesis of nitric oxide. Not only does nitric oxide help dilate your vessels to keep blood flowing efficiently and reduce the risk of high blood pressure, but it’s also involved in regulating the immune system.

This fruit is also a great source of vitamin C, a key micronutrient that does double duty, acting as both an antioxidant and immune enhancer to keep your body healthy and ward off chronic disease. Antioxidants can help fight free radicals and protect the cells against oxidative damage and stress.

2. May Improve Heart Health

Watermelon contains a good amount of both potassium and magnesium, two important nutrients used to help remedy conditions like high blood pressure. Consuming proper amounts of potassium and magnesium from a nutritious diet seems to be associated with improved heart health, according to research, along with a decreased risk of death from heart disease.

A review published in the journal Advances in Nutrition showed that eating plenty of potassium-rich foods like fruits and vegetables can positively impact blood pressure levels, which may be useful in reducing the risk of conditions such as stroke and heart attacks.

Lycopene also benefits heart health by reducing inflammation, fighting oxidative stress and potentially
