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].

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].
