When You Eat Too Many Bananas, This Is What Happens
Bananas are known for their nutritional benefits as a quick on-the-go snack. But hidden behind the vitamin-rich reputation are some risks to overeating them. Here's what can happen when you go overboard on bananas.
Although bananas are high in fiber, which could help you stay full longer, they are also packed with carbohydrates, calories, and sugar, which can lead to weight gain if eaten in excess (via Eat This, Not That!). In fact, over 90 percent of the calories in bananas come from carbohydrates, according to Healthline.
The high sugars can also spike your blood sugar — especially in overripe bananas. Those who are diabetic should monitor their banana intake. The sugar in bananas can also have an effect on your teeth like candy. Studies show that the sugars in bananas can cause more damage than chocolate (via Orlando Sentinel).
While bananas are an important part of the "BRAT" diet for those experiencing bowel issues, consuming too many can have the opposite effect. The tannic acid in bananas can cause uncomfortable bowel issues (like constipation) that could become serious if untreated.
How many bananas should you eat daily?
As with most foods, moderation is key. Sticking with just one fruit source like a banana can cause nutrient deficiencies. In the case of bananas, your diet may lack protein, fat, calcium, vitamin D or iron (via Healthline). The nutrition makeup of bananas can also lead to some side effects, like migraines and sleepiness.
In more rare, serious cases, the high levels of potassium you could gain by eating numerous bananas could cause you to develop hyperkalemia, a condition that impairs muscle and nerve cells, according to Eat This, Not That!.
So how many bananas should you eat in one day? There's no magical number, as it can vary based on your dietary requirements and personal nutrition. However, a general rule of thumb for moderate banana consumption is 1-2 per day for most healthy people.
Overall, bananas can be a healthy addition of much-needed fruit to a well-rounded diet. If you have concerns about bananas and your personal nutrition plan, it is best to consult with your medical team for guidance.
