This might be the most misinterpreted aspect of the nutritional value of bananas. Since they are sweet fruits, many people, particularly health-conscious ones or those suffering from certain conditions, avoid them.
The glycemic index (GI) of bananas ranges from low to medium, being about 42 to 62 according to their ripeness level. The GI indicates the effect of food consumption on the level of glucose in our bloodstream after eating it. This is because the presence of dietary fiber and resistant starch makes bananas not produce the high blood sugar spikes typical of processed foods like white bread.
According to scientific studies, unripe green bananas have a lower GI than ripe ones with black spots on them. It is easy for a healthy body to digest the sugar contained in bananas. Diabetic patients should be very cautious regarding the intake of portions of bananas, but it does not mean they cannot eat this fruit alongside other foods like proteins.
Weight Management: The Satiety Factor
Bananas have been accused of being fattening, which is quite the opposite of the truth. Satiety plays an important role in successful weight loss. Feeling fuller leads to less consumption of calorie-rich, processed foods.
Fiber in bananas works as a satiety inducer because:
it increases bulk in the stomach;
it helps slow stomach emptying.
By substituting a 300-calorie snack bar with a 100-calorie banana, not only do you cut down the number of calories, but you also provide your body with nutrients that help regulate metabolism.
A Shield of Antioxidants
People usually assume that berries and dark leafy vegetables are the only foods that can provide antioxidants, but bananas have a lot of these essential substances. There are different kinds of antioxidants, such as flavonoids and dopamine and catechins.
Antioxidants neutralize free radicals within the body, which cause oxidative stress. With time, oxidative stress leads to aging and different diseases such as cardiovascular disorders and some cancers. Moreover, bananas also have vitamin C, which strengthens the immune system and increases resistance to infections.
Kidney Health and Longevity
Kidneys are not given enough credit when it comes to keeping our blood clean and controlling the balance of minerals within us. Potassium plays a key role here. Several longitudinal studies have shown that females who consume bananas two to three times weekly have a much lower risk of kidney diseases in the following 13 years.
Moreover, through proper regulation of our blood pressure, bananas also help to safeguard the kidneys from any harm. One of the primary reasons behind kidney disease is high blood pressure. On the other hand, people with severe kidney diseases and on a low-potassium diet must discuss their diet plan with their doctors.
