5 Things You Don’t Know About Watermelons, and Why You Should Eat Them

As symbols of summer, watermelons grace picnics, barbecues, and other outdoor gatherings during the warm months. But did you know that watermelons also offer a variety of health benefits? This article will delve into the captivating world of watermelons and explore the health benefits of watermelons, revealing their hidden potential.

Historical and Nutritional Content of Watermelons

The watermelon, with its refreshing, sweet, and hydrating flesh, has an intriguing history of over 4,000 years. Originally believed to have originated in the Kalahari Desert of Africa, the first recorded watermelon harvest occurred in Egypt nearly 5,000 years ago. Watermelons have been found in hieroglyphics, and even the seeds were discovered in the tombs of Pharaohs, a testament to their cultural significance. One can also speculate that ancient civilisations might have understood the health benefits of watermelons.

This fruit travelled along merchant routes to other parts of the world. The Moors introduced it to Europe in the 13th century, and by the 16th century, explorers and traders had taken it to the New World. Today, watermelon is cultivated in many countries globally, with China being its largest producer. Culturally, the watermelon continues to signify abundance, refreshment, and summer merriment across various societies, partly due to the health benefits of watermelons.

Different Types of Watermelons

Watermelons exist in a surprising array of sizes, colours, and tastes. Each variety, no doubt, has its share of the health benefits of watermelons:

  • Red Watermelon

The iconic variety, is identified by a green-striped rind and a vibrant red interior. It is revered for its juicy sweetness and contains numerous small, edible black seeds.

  • Seedless Watermelon

A product of plant breeding, the seedless variety is similar in taste to its seeded counterpart. The convenience of these seedless varieties encourages more people to incorporate watermelons into their diets, thus reaping the health benefits of watermelons.

  • Mini Watermelon

Mini watermelon offers the same health benefits of watermelons in a single-serving size, making it an ideal choice for those living alone or those who desire a smaller, easier-to-manage fruit. Despite the different serving sizes, the concentration of nutrients remains high, contributing to the health benefits of watermelons.

  • Yellow Watermelon

Yellow watermelon, with its unique colour and flavour profile, is another excellent source of the health benefits of watermelons. Not only does it offer a novel sensory experience, but it also delivers the same nutritional value, ensuring that the health benefits of watermelons are not compromised.

Nutritional Content of Watermelon

Beyond its deliciousness, watermelon is a nutritional powerhouse. Its high water content makes it incredibly hydrating, but the benefits don’t stop there. The health benefits of watermelons arise from these key nutritional components:

  • Vitamin C

This essential vitamin boosts the immune system, promotes healthy skin, and provides antioxidant protection against cellular damage. It plays a substantial role in the health benefits of watermelons.

  • Vitamin A

Crucial for maintaining eye health, this vitamin also supports immune function and promotes skin health. Watermelons are present in beta-carotene, giving the fruit its vibrant colour. Vitamin A’s ability to promote skin health and maintain eye health amplifies the health benefits of watermelons.

  • Potassium

An electrolyte that helps regulate fluid balance, nerve signals, and muscle contractions. Potassium-rich foods like watermelon can support heart health by maintaining healthy blood pressure. The presence of potassium augments the health benefits of watermelons. 

  • Magnesium

This mineral is involved in over 300 biochemical reactions in the human body, ranging from protein synthesis to blood pressure regulation. The magnesium in watermelons contributes to the health benefits of watermelons by participating in numerous biochemical reactions.

  • Lycopene

The red flesh of watermelons is rich in this potent antioxidant. Lycopene has been associated with heart health, sun protection, and a reduced risk of certain types of cancer. A study in the Journal of Agricultural and Food Chemistry found that the bioavailability of lycopene from watermelon is higher than that from tomato juice. 

This combination of hydration and nutrition makes watermelons an excellent dietary choice, particularly during the summer when the body’s need for hydration and essential nutrients peaks. Therefore, incorporating watermelon into your diet can enhance the health benefits of watermelons.

Surprising Facts about Watermelons

As we delve deeper into the world of watermelons, their seemingly endless health benefits continue to amaze us. The nutritional prowess of this vibrant fruit goes far beyond its juicy flesh. Its seeds and rinds are edible and nutritious, too. The watermelon’s exceptional hydration potential, unique yellow variety, effectiveness as a post-workout aid, and even its potential to boost fertility set it apart as a nutritional gem. So, let’s unpack these surprising facts about watermelons.

  1. Versatility of Consumption

While we typically enjoy the sweet, crisp flesh of the watermelon, its rinds and seeds often get tossed aside. However, these components are edible and offer their own set of nutritional benefits. Although less sweet, the rinds are fibre-rich and contain some vitamin C. They can be juiced, pickled, or even incorporated into stir-fries. The seeds, often roasted, are packed with protein, vitamin B, magnesium, and healthy fats. All these components add to the overall health benefits of watermelons.

  1. Hydrating Powerhouse

Watermelon is an incredible hydrating powerhouse, with water constituting about 92% of the fruit. Lauren Harris-Pincus, a registered dietitian and author, said, “Watermelon is a great choice for hydration since it’s over 90% water.” She also noted that watermelon is a good source of vitamin C, which can boost the immune system, and contains high levels of the antioxidant lycopene. This undoubtedly adds to the health benefits of watermelons.

  1. Special Yellow Watermelon

The yellow watermelon, while a delightful twist on the traditional red, is more than just a pretty fruit. Its golden flesh is rich in beta-carotene, the same nutrient that gives carrots orange colour. Beta-carotene is a powerful antioxidant that supports eye health, skin health, and immune function. This special variant provides a different perspective on the health benefits of watermelons.

  1. Post-Workout Companion

Watermelon has been identified as an excellent post-workout companion with L-citrulline, an amino acid. According to a study published in the Journal of Nutritional Biochemistry, watermelon consumption was found to lower blood pressure and improve arterial function in overweight adults with hypertension. The study’s authors attributed this benefit to the high levels of L-citrulline, an amino acid found in watermelons that helps improve blood flow. This points towards the sports nutrition and cardiovascular health benefits of watermelons.

  1. The Fertility Booster

Beyond its many known benefits, recent studies suggest that watermelon may even support fertility. A 2023 study found a link between watermelon consumption and improved reproductive health factors. This is primarily attributed to lycopene and citrulline’s presence in the fruit, both known to improve blood flow and erectile function. However, more research is needed to confirm and understand the full scope of watermelon’s potential fertility benefits.
