Introduction
The main goal of this article is to compare bananas and potatoes in terms of nutrition. These products are different in many ways; nutrition, taste, and appearance. However, they both are very healthy.
Varieties
Bananas belong to the Musa genus; therefore, they are known as fruits and as vegetables. Bananas have many different varieties. The most common species are Cavendish Bananas and Lady's Finger Bananas.
The potato plant is a part of the Solanaceae family, the Solanum genus. The Solanaceae family of flowering plants also includes tomatoes, chili, and bell peppers.
The most known species are Classic Russet and Bannock Russet potatoes [1] [2].
Uses
Bananas and potatoes are the most used products in the kitchen. Potatoes are spread around the world and have become a staple crop in many countries. They are mainly used boiled, baked, roasted, fried in a massive range of different dishes.
Bananas can be eaten both raw and cooked. They are used in various dishes, salads, muffins, smoothies, and so.
Nutrition
Bananas and potatoes have very different nutritional profiles. Both are rich in micronutrients. To better understand the difference, find the nutritional infographic at the bottom of this page.
Micronutrients
Banana and potato are relatively equal in micronutrients. Potatoes contain more protein and fewer sugars than bananas. On the other hand, bananas contain more fiber and fats than potatoes. The amount of cholesterol is equal [3].
Calories
Overall, bananas contain more calories than potatoes. Each banana has about 89 calories per 100 g, while each potato contains 77 calories per 100 g.
Vitamins
The vitamin content of bananas and potatoes is comparatively equal. Banana contains 30 times more Vitamin A and nine times more Vitamin E. Vitamin B2, Vitamin B5, Vitamin B6, and Folate are also high in bananas. Nonetheless, potatoes have more Vitamin C, Vitamin B1, Vitamin B3, and Vitamin K. Vitamin B1 and Vitamin K levels are almost two times higher in potatoes than bananas [3] [4].
Vitamin Comparison
Minerals
In general, potatoes are relatively richer in minerals than bananas. It contains two times more iron and two times more phosphorus. The levels of zinc, calcium, and copper are also higher in potatoes. On the other hand, bananas are rich in magnesium and have less sodium. The amount of potassium is also high in potatoes [3] [4].
Mineral Comparison
Potassium
Our body needs potassium because it may help to reduce the risk of kidney stones and normalize lower blood pressure. In this case, potatoes have more potassium than bananas. It has 425 mg per 100 g, whereas bananas have 358 mg potassium per 100g.
Glycemic Index
The difference between the glycemic indexes of these two is enormous. The estimated glycemic index of bananas is 48, while the glycemic index of potatoes is equal to 86. Bananas are considered a low glycemic index food.
Health Benefits
Weight Loss
Bananas and potatoes are middle calories products that hold tiny proteins and fats. Eating bananas can't directly lead to weight loss; nevertheless, some components can help reduce bloating and replace processed sugars. Vegetables can be included in all diets when prepared with the correct methods. For example, the Potato Diet claims to help you lose one pound a day by eating nothing but plain potatoes. However, the calories and exact diet depend on the cooking methods of these vegetables [5] [6].
Cardiovascular Health
Bananas have high potassium and low sodium content; their intake is associated with a lower risk of cardiovascular disease and lower blood pressure.
Banana and potato both are high in fiber, which studies prove role in preventing heart disease. Fiber can lower both blood pressure and cholesterol. However, according to the study, a high intake of baked, boiled, mashed, or fried potatoes may increase the risk of hypertension. This effect may be explained by a high glycemic load of potatoes [7] [8].
Cancer
According to the Swedish study, the women who ate 4-6 bananas a week cut in half their risk of developing kidney cancer. Moreover, bananas contain lectins which have a distinctive role in the reduction of cancer metastasis.
Acrylamide is a chemical compound that can form in some foods during high-temperature cooking processes, such as French fries, potato chips, foods made from grains. High doses of acrylamide can cause nerve damage. Lab animal studies show that acrylamide causes cancer [9] [10].
Diabetes
Based on studies, potato consumption leads to an increased risk of developing type 2 diabetes, associated with potatoes' high glycemic index and glycemic load. However, more research on humans is needed [11].
Bananas are a good source of fiber; besides, they are considered a low glycemic index food. Unripe bananas can be included in diabetic diets in moderation [10].
Good Digestive Health
Dietary fiber has been associated with improving digestive health. Moreover, resistant starch in bananas and potatoes is mainly converted into fatty acid butyrate, the preferred food source for gut bacteria. Butyrate may help patients with inflammatory bowel diseases such as Crohn's disease or ulcerative colitis. [12].
Good Eye Health
Bananas are suitable for your eye health. According to studies, Vitamin A present in bananas plays an essential role in keeping the mucus membranes in the eyes healthy. Besides, they are also high in carotenoids, which may help protect your eyes from the damaging effects of blue light and reduce your risk of macular degeneration, especially when you are older [13].
Side Effects
Toxicity
Some potato specials may produce a toxic compound called solanine, a glycoalkaloid. Mainly, under certain unfavorable conditions, such as pests, potatoes can increase the production of solanine, especially when kept in sunlight. Solanine gives potatoes a bitter taste and a green color, which may include symptoms like diarrhea, vomiting, fever, and abdominal pains [14].
Allergy
Both products are likely safe in the amounts typically eaten as food. However, an allergic reaction to bananas usually has people who are sensitive to latex. The symptoms include irritation and itching of the mouth, diarrhea, and gas [15].
A potato allergy can affect people of any age and cause-specific compounds of potato, patatin, or saline. The symptoms mainly include sneezing, runny nose, hives, and itchy skin [16].
