Watermelon is a seasonal fruit and is mostly grown in temperate and tropical regions. Watermelon was harvested 3500 BC in nowaday Libya, and with time it was grown in Egypt. During the Roman Ages, it was spread throughout Europe.
China is the highest producer of watermelons. The newly modified watermelons are sweeter, disease-resistant, and grow after 100 days of planting the seed.
On the other hand, banana is one of the most widely harvested fruits in the world.
It is native to India and Southeast Asia, but it is currently grown worldwide.
Bananas may be eaten raw, blended into smoothies, and even used as an ingredient in baking.
Bananas grown now are not the same as those found in the wild. Wild bananas were substantially smaller in size and had seeds within. The wild-type bananas were transformed into contemporary domesticated bananas in the early ages.
In this article, we will discuss general differences, nutritional content comparison, weight loss and diet, and health impacts.
In this section, we will discuss price and availability, taste, shelf life, and culinary world usage.
Price and availability
Bananas are always available nearly all around the world, and they are cheaper than watermelons. On the other hand, watermelon is available during the summer season.
Watermelon is watery and refreshing, and it has a sweet flavor. On the other hand, bananas are starchy, and their sweetness depends on their ripeness stage.
The shelf life of watermelon is longer compared to bananas. After 5-7 days, the banana turns ripe; however, watermelon can stay unrefrigerated for more than one week.
Culinary world usage
Bananas are widely used in the culinary world. It can be eaten raw, turned into smoothies, used in baking. The peel can be turned into banana flour, an alternative to other flours. In addition, bananas are fried in some cuisines and used as part of meals.
However, watermelon doesn’t have a wide usage as much as a banana, and it is mostly used as a fruit and juice.
Nutritional content comparison
This section will compare the difference between the macronutrients, vitamins, and minerals of watermelon and banana according to 100g of each.
100g of watermelon is composed of 92g of water so technically speaking, watermelon is 92% water. On the other hand, a banana is composed of 75g of water.
Furthermore, bananas are richer in macro, vitamins, and minerals, mainly since watermelons are 92% water. Technically the nutrients are in a diluted state.
The glycemic index of watermelon is categorized as high, whereas bananas are considered as low glycemic index foods. The glycemic index of watermelon is 76 compared to that of banana, which equals 48.
Bananas are higher in calories, three times the amount of watermelon.
The net carbs of bananas are much higher than that of watermelon. Bananas contain nearly three times more carbs than watermelon.
It is important to talk about the fiber content of each fruit. Bananas are 6.5 times richer in fibers than watermelon. This has significant characteristics when it comes to gastrointestinal health and wellbeing.
The total amount of protein is not of high significance.
The total amount of fat is negligible.
Watermelon contains minerals; however, their amount is not of high significance. On the other hand, bananas are richer in copper, magnesium, and potassium. Bananas also contain higher amounts of other minerals, seen in the comparative diagram below. However, they are not of high significance.
Watermelon is richer in vitamin A compared to bananas. Bananas are richer in vitamin C, folate, B2, B3, B5, and B6. The vitamin B6 content of bananas is of high importance.
In the diagram below, we can see the comparison between these foods.
Weight loss and diets
Watermelon and bananas are a good addition to be added to everyday diets. Since watermelon is seasonally available, that would be limited to 3-4 months a year. However, bananas are available year long and can be part of everyday diets.
Vegans can eat both bananas and watermelon. In addition to that, banana is a special fruit considered in the vegan diet, and bananas can be used to bake cakes and prepare ice cream since they can replace eggs and creams. Vegans use bananas instead of eggs as an alternative ingredient.
Since they are lower in carbs, watermelons can be eaten on a ketogenic diet. Compared to bananas which are high in carbs and cannot be consumed in the keto diet.
Bananas can be used in making energy shakes and baby foods. It is balanced and contains fibers which is a good addition to everyday diets. On the other hand, watermelon is mostly water. It is a good refreshing fruit that can be enjoyed during hot weather. Watermelon can also be used in making smoothies and juices similar to bananas.
Anti-diabetic effects are found in bananas. In order to absorb carbohydrates, an enzyme in the digestive tract breaks down large chain molecules of sugar into smaller sugar molecules. Bananas include enzymes that prevent this from occurring, limiting the amount of sugar absorbed from the digestive system and keeping blood sugar levels in balance. (1)
Watermelon also has anti-diabetic properties; it reduces the activities of enzymes and transporters that help in breaking down glucose into the blood. Thus, not causing spikes in glucose levels. (2)
Lycopene present in watermelon reduces oxidative stress and free radicals, in turn reducing the risks of developing cancer. (3)
Lectins are active proteins found in bananas that act on cancer cells and inhibit their growth (multiplication). As a result, cancer proliferation and metastasis are reduced.
Overall there is a reduction of cardiovascular diseases and atherosclerosis in patients who consumed watermelon, and this was mainly due to the effect on lipid metabolism, and reduction of risks of cardiovascular diseases was observed. (5)
Bananas are rich in phenolic compounds that reduce antioxidants and the damage caused by free radicals. This, in turn, reduces inflammation and several degenerative diseases. (6)
Green bananas are richer in fibers than compared ripe bananas, and this positively affects the gut microbiota. In addition to that, the fibers give a sensation of fullness which causes a reduced frequency of eating and ultimately weight loss. (7)(8)
When it comes to bananas, it is best to avoid them if you are using MAOI medicines, which are a form of antidepressant. Some people may get hypertensive crises as a result of the combination of MAOI medications with bananas. (8)
