Improving Elimination
Bananas are a smart move if you suffer from elimination problems. A bout of
diarrhea can quickly deplete your body of important electrolytes. Bananas can
replenish your stores of potassium, one of the most important electrolytes,
which helps regulate heart function as well as fluid balance.
In addition, bananas contain pectin, a soluble fiber (called a
hydrocolloid) that can help normalize movement through the digestive tract and
ease constipation. Bananas also contain resistant starch, but this amount
varies depending on their degree of ripeness. In their lesser ripe stages,
bananas score as low as 30 on the glycemic index (below 50 would be considered
low). In their riper stages, this number usually rises to a moderate level in
the 60's. All of the above features help place banana in a more favorable
digestive light than might otherwise be expected for a sugary fruit.
