Top 5 Health Benefits of Watermelon
Watermelon has long been considered a nutritious, healthy fruit that’s both delicious and fun to eat- but are there real health benefits to adding it to your diet? It turns out that the answer is yes.
While most people associate watermelon with hot summer days and picnics, this fruit actually has several nutritional benefits that make it an excellent addition to your diet year-round.
Here are some of the many benefits of watermelon that will have you eat it daily! (in no particular order)
Good for Weight Loss
You must be wondering how watermelon is good for weight loss.
Watermelon is low in calories but high in water content, making it an excellent food for weight loss. The high water content can help you feel full and eat less overall, and the nutrients in watermelon may help boost your metabolism.
Besides, the fiber content increases too, which can help you feel full longer, making you less likely to overeat later.
Prevents Growth of Cancer Cells
In addition to being loaded with vitamins and nutrients, watermelon also contains lycopene, an antioxidant known to lower the risk of developing certain types of cancer by protecting cells from damage, for example, prostate cancer and other cancers.
Keeps You Hydrated
Watermelons are high in water content. So, it makes them an excellent way to stay hydrated while providing several essential nutrients.
Improves Hair Growth
People often say that consuming a lot of watermelons is suitable for your hair because it provides the essential hydration needed to keep strands and follicles healthy. While this may be true, there are other ways to care for your hair.
Anti-inflammatory Properties
Recent research has shown that watermelon may have anti-inflammatory properties. These properties help reduce the body’s inflammatory responses and improve symptoms of allergies, asthma, inflammatory bowel disease, rheumatoid arthritis, and type 2 diabetes.
Watermelon Side Effects Due To Overeating
Did you know that consuming too much watermelon can cause health problems?
It might seem counterintuitive, but there are three health risks of consuming watermelon (that you didn’t know about). Here they are. You’ll never look at the popular summer fruit the same way again.
Risks Of Too Much Vitamin A
Too much vitamin A can be dangerous as it can increase the risk of osteoporosis and cancer. For pregnant women, too much vitamin A can cause congenital disabilities.
There is also a chance that some people will experience allergic reactions to eating watermelon due to the fact that they are allergic to melon or cucumber, both of which are in the same family as watermelons.
Risks Of Too Much Lycopene
Lycopene is what gives watermelon its rich red color. It has been thought to protect against cancer, heart disease, and macular degeneration. However, too much lycopene can also be harmful to some people with diabetes or kidney problems.
Also, eating large amounts of lycopene-rich foods may result in diarrhea, stomach cramps, nausea, vomiting, and dizziness.
Risk of too much fructose
Watermelon is a high fructose (fruit sugar) fruit. According to the USDA, 100 grams of watermelon has 6 grams of fruit sugar. Studies have also shown that overconsumption of high-fructose fruits has been linked to increased body weight, belly fat, and triglycerides.
Risks Of Too Much Oxalic Acid
Oxalic acid is the compound that makes many fruits and vegetables taste sour, apples, oranges, and rhubarb. It also has a mild laxative effect, so people who eat a lot of these foods will sometimes get an upset stomach or diarrhea.
Although the concentration of oxalic acid in watermelon is less than 0.5%, it is still there. And consuming too much oxalic acid can lead to oxalate kidney stones or gout.
Risk Of Too Much Citric Acid
Because the fruit contains an acid called citric acid, which is present in high concentrations when the watermelon is under-ripe, this could be bad for tooth enamel. Usually, a cup of watermelon contains around 12 milligrams of vitamin C, which can be easily overconsumed if you do not control the portion.
Watermelon vs Watermelon Juice- Which One is Healthy?
Watermelon is delicious, but in order to reap the maximum benefits, it should be consumed as whole fruit, not in juice form.
The first problem with watermelon juice is that it lacks the fiber that comes from the skin and pulp of fresh watermelon. A cup of watermelon contains around two to three grams of fiber, while only trace amounts are found in one cup of watermelon juice.
Consuming less than 20 grams of fiber daily can lead to constipation and other digestive problems. This is definitely something to consider if you’re relying on watermelon juice for your daily dose.

Is Watermelon Water Good For You?
Although you will get the same amount of hydration from watermelon juice as you would with consuming the fruit, you risk consuming additional sugar through the juice.
It is evident that fruit juices contain added sugar. So, when the added sugar in the juice is combined with the natural fructose of watermelon, you tend to consume a lot of sugar at once.
Therefore, consuming whole watermelon fruit instead of juice is a healthy option.
How many watermelons Should I Consume Every Day?
Watermelon has high amounts of lycopene and even more significant benefits when combined with selenium, zinc, and copper. It contains other nutrients like beta-carotene (vitamin A), lutein, potassium, folate, and vitamin C.
That said, some caveats can come with overeating watermelon. Eating excessive watermelon over a short time can harm one’s health, as you have seen above.
You might have yet to realize this, but the amount of watermelon a person should consume varies. Some people will be able to have a little more than others and still stay within the recommended daily serving size. Consuming a maximum of one or two cups of watermelon won’t do any harm to a healthy individual.
If you are too concerned about how much is right for you, speak with your doctor or calculate the nutritional information from the chart above.
FAQs
Are watermelons healthy for diabetics?
For people with diabetes, the sugar in watermelons can be problematic if consumption is not controlled. Watermelons have natural sugars called fructose, which can trigger the condition when consumed too much at a time.
Are watermelons healthy for pregnancy?
Watermelon is one of the healthiest fruits to consume during pregnancy. Pregnant women suffer from constipation, so the high fiber content in watermelon helps ease it.
This fruit also keeps their body hydrated and nourished. Also, the numerous healthy vitamins and minerals in the fruit are good for fetal development.
Is watermelon good for diarrhea?
Diarrhea means excessive loss of water from the body. Since watermelon is rich in water, consuming it when you are suffering from diarrhea can help your body with hydration.
In this case, consuming watermelon juice is better to avoid the fiber intake, as drinking too much fiber during diarrhea can increase the condition.
Are watermelons good for gastritis?
Watermelon is a safe fruit to eat even if you have gastritis. It won’t trigger or worsen the condition because watermelon is a low-acidic or alkaline fruit.
A fully ripe watermelon has a pH level of 9. It helps to neutralize the acid produced in gastritis.
Final Thought
Are watermelons healthy? Yes, watermelons are healthy fruit as mother nature has instilled many good things in them; we all know that. But excess of anything has an adverse effect, and that’s what I was trying to show you.
You might have been stuffing your tummy with watermelon, thinking it won’t affect your health negatively. Although it won’t harm you in a single day or two, you should stop immediately if you continue doing it for the entire summer season.

Dark Chocolate Guinness Fudge


Come on and join me over on the dark side. It’s been heaven over here lately. I can’t get enough of dark chocolate. I will let you in on a little secret..this is my first attempt ever at making fudge. And you know what? I nailed it! I am really proud of this fudge. It is moist, rich, and chocolaty smooth. It has just the right essence of Guinness beer. Even had my sister-in-law who doesn’t like beer, but loves dark chocolate, loved it. It doesn’t taste like alcohol, just a really good dark chocolate.

After my post about Dark Chocolate Guinness Rice Krispie Treats, I went back to look at all my pictures from Ireland two years ago and found this picture. Let me tell you, this was some good chocolate. I wanted to bring those tastes together again. That’s how the idea of the fudge came about. Then I found an easy chocolate fudge recipe online and manipulated it to what I wanted.

This recipe is so easy and doesn’t have that many ingredients. I used the same method of boiling down the beer, that I used in the other recipe. Except this time I wanted more of that Guinness flavor, so I used a whole can. I know that leaves you with no left overs to drink as you make this, but you can always pop open another can.

I boiled the beer down to 1/4 cup, twice as much as I used in the Rice Krispie Treats. And I used two different chocolates for an intense flavor. The walnuts are optional. I didn’t add that much, so they don’t interfere with the other flavors.

After the fudge was cooled off, I drizzled a generous amount of caramel over the whole thing and sprinkled it with sea salt. I only had fine grain sea salt, but it worked just as well. It melted into the caramel after awhile, but the flavor was still there. It just tastes like a salted caramel. The salt cuts down a little on the richness of the chocolate.

A box of these makes a perfect gift for those Irish loved ones in your life or those dreaming about going to Ireland. Or even those who just love chocolate and beer. Enjoy!
