There are bananas galore in grocery stores, and when we buy a bunch we hardly focus on their nutritious value and health benefits. There are a much greater number of them than we think! Bananas are great for everyone, regardless of sex and age.
What makes them healthy?We’d better start with what they are law on: protein, fats and, consequently, calories. What bananas are high on are net carbs, starch, water, and fiber. Other key substances and elements include potassium, vitamin C, vitamin B6, copper, magnesium, and manganese. As a fruit ripens, the starch bulk begins to transform into carbohydrates – fructose, glucose, sucrose.
What’s the role of these ingredients?
Heart, blood sugar and digestion
- Potassium plays a key role in maintaining the functioning of the heart and blood system. Particularly, it regulates blood pressure and prevents related cardiac and vascular issues. Research indicates that men who eat bananas and other potassium-rich meals are less prone to strokes.
- Bananas do contain carbohydrates, and it is one of the few foods that contain healthy amounts of them. The average glycemic index of a medium-sized banana is 50, ranging between 30 in unripe and 60 in ripe bananas. It is a well-known fact that bananas do not cause blood sugar to soar in healthy people. Ripe bananas are rich in fructose-containing carbohydrates (fructooligosaccharides), which, instead of being metabolized in the digestive system, reach the lower bowel and feed healthy bacteria.
- Fiber (pectins and resistant starch) helps the body to adjust digestion and regulates the metabolism of carbohydrates. As a banana ripens, it accumulates sugar and water-soluble pectins simultaneously. The fiber blocks excess sugar intake and keeps general blood sugar level stable.
