In the US, July is National Watermelon Month, so named not only because a cool, refreshing slice of watermelon represents the epitome of summer, but also because watermelon harvests peak this month.
Watermelon is now the most-consumed melon in the US (followed by cantaloupe and honeydew). This cousin to cucumbers, pumpkins, and squash is thought to have originated in Egypt close to 5,000 years ago, where it is depicted in hieroglyphics.
Today, upwards of 300 watermelon varieties are grown in the US and Mexico (although only about 50 are popular). You may think you know everything there is to know about this summertime fruit, but allow me to surprise you… watermelon is more than just delicious… it’s a super-healthy addition to your diet (in moderation, of course).
You just need to be careful when eating any melon, including watermelon to follow the advice of Wayne Pickering in my interview. Eat melon alone or leave it alone because it will make your stomach groan. So ideally, no food 30 minutes before or after eating melons.
1.Watermelon Has More Lycopene Than Raw Tomatoes
Lycopene is a powerful carotenoid antioxidant that gives fruits and vegetables a pink or red color. It’s most often associated with tomatoes, but watermelon is actually a more concentrated source.
Compared to a large fresh tomato, one cup of watermelon has 1.5 times the lycopene (6 milligrams (mg) in watermelon compared to 4 mg in a tomato).More on why lycopene is so important shortly…
2.Watermelon Juice May Relieve Muscle Soreness
If you have a juicer, try juicing about one-third of a fresh watermelon and drinking its juice prior to your next workout. This contains a little over one gram of l-citrulline, an amino acid that seems to protect against muscle pain.
One study found that men who drank natural unpasteurized watermelon juice prior to their workouts had reduced muscle soreness 24 hours later compared to those who drank a placebo.
You do need to be careful with drinking watermelon juice, though, as it contains a significant amount of fructose. It may be better to eat the entire fruit, or opt for these other tips to prevent muscle soreness.
3.Watermelon Is a Fruit and a Vegetable
Remember how watermelon is related to cucumbers, pumpkin, and squash? That’s because it’s part vegetable and part fruit (it’s a sweet, seed-producing plant, after all). The other clue that watermelon is both fruit and vegetable? The rind is entirely edible…
4.You Can Eat Watermelon Rind and Seeds
Most people throw away the watermelon rind, but try putting it in a blender with some lime for a healthy, refreshing treat. Not only does the rind contain plenty of health-promoting and blood-building chlorophyll, but the rind actually contains more of the amino acid citrulline than the pink flesh.
Citrulline is converted to arginine in your kidneys, and not only is this amino acid important for heart health and maintaining your immune system, but it has been researched to have potential therapeutic value in over 100 health conditions.
While many people prefer seedless watermelon varieties, black watermelon seeds are edible and actually quite healthy. They contain iron, zinc, protein, and fiber. (In case you were wondering, seedless watermelons aren’t genetically modified, as they’re the result of hybridization.)
5.It’s Mostly Water
This might not be surprising, but it’s still a fun fact; watermelon is more than 91 percent water. This means that eating watermelon with you on a hot summer day is a tasty way to help you stay hydrated and avoid dehydration (it’s not a substitute for drinking plenty of fresh water, however).
Watermelon Extract May Significantly Reduce Blood Pressure
New research also highlights the role of watermelon nutrients on heart attack prevention, via a significant reduction in blood pressure. Obese study participants who received citrulline and arginine supplements derived from watermelon extract had significant improvements in blood pressure and cardiac stress, both while at rest and undergoing a stressful cold-water test. According to the researchers:
“Watermelon supplementation reduced aortic BP [blood pressure] and myocardial oxygen demand during CPT [cold pressor test] and the magnitude of the cold-induced increase in wave reflection in obese adults with hypertension. Watermelon may provide cardioprotection by attenuating cold-induced aortic hemodynamic responses.”
Remember, in your body the citrulline in watermelon is converted into L-arginine, which is a precursor to nitric oxide. Adequate nitric oxide is required to enable you blood vessels to stay relaxed and open for blood flow, which is one reason why it may help lower blood pressure.
Watermelon for Inflammation, Sexual Health, and More
L-arginine may also help with erectile dysfunction by helping to relax your blood vessels, including those supplying blood to your penis – and that’s why watermelon is sometimes referred to as “Nature’s Viagra.” In fact, citrulline supplementation has been found to improve erection hardness in men with mild erectile dysfunction.
What else is watermelon good for? It’s rich in anti-inflammatory substances. For instance, watermelon contains the anti-inflammatory antioxidant lycopene as well as cucurbitacin E, or tripterpenoid, which reduces the activity of the pain and inflammation-causing enzyme cyclooxygenase – the same enzyme blocked by COX-2 inhibitors, which include most NSAIDs like aspirin and ibuprofen. While being very low in calories (about 46 calories in a cup), watermelon also contains an impressive variety of other important nutrients in which many Americans are lacking, including: Vitamin C, Vitamin B6, Potassium, Vitamin A.
