It is generally safe to eat one or two bananas per day. However, if you eat too many bananas, you may experience some side effects, such as:

• Weight gain: Bananas are a high-calorie food, so eating too many of them can lead to weight gain.

• Stomach upset: Bananas are high in fiber, and eating too much fiber can cause stomach upset in some people.

• Allergies: Bananas are a common allergen, so if you have allergies, you should be careful about eating them.

Overall, bananas are a healthy and versatile fruit that can be enjoyed at any time of day. However, it is important to eat them in moderation and to be aware of any potential side effects.
