Bananas
Bananas are a healthy addition to almost any diet, but too much of any single food, including bananas, could do more harm than good. Bananas are not typically considered a high-calorie food. However, if your banana habit is causing you to eat more calories than your body needs, it could lead to unhealthy weight gain.
Additionally, over 90% of the calories in bananas come from carbs. In unripe or green bananas, the main source of carbs comes from starch. As the fruit ripens, the starch converts to sugar. Thus, by the time your banana is ripe enough to eat, a large proportion of the calories may be coming from sugar. Carb over-consumption without balancing it with proteins and healthy fats could make blood sugar control more difficult for those with blood sugar conditions, such as diabetes.
Additionally, eating too many bananas may lead to nutrient deficiencies, especially if you’re not making room for foods that contain the nutrients bananas are lacking, such as protein, fat, calcium, vitamin D, and iron. Therefore, we should eat 2 bananas a day to have a healthy amount.
