Besides, bananas are packed with plant compounds that have proven anti-stress and anti-inflammatory properties. According to the World Health Organization, you should eat five servings of fruits and vegetables per day for a sound mind and body.

Very low in protein and fat

Sugars constitute a major calorie portion of bananas, leaving only 8% for fats and proteins combined. Unlike what the diet culture may have you believe, fats are essential to your health. They are not only a source of energy but they also improve brain health, contribute to hormone production, and absorb fat-soluble vitamins. 

Proteins,on the other hand, are needed for proper immune function, tissue repair, muscle building, and bone health.

Although the bananas are wholesome, they are not nutritionally complete. If you like to snack on bananas, supplement it with protein or a healthy fat-containing food such as a handful of walnuts, peanut butter, or a boiled egg. 

Too much of a good thing 

Bananas provide a fair share of calories but if you eat too much of it, unhealthy weight gain will be the consequence. Unripe or green bananas are rich in starch that breaks down into sugar as the fruit ripens over time. 

The rich amount of carb (over 80%) content of bananas is why you should be cautious of over-consumption. Indulging in high-carb foods is especially unhealthy for individuals with blood sugar conditions such as diabetes or prediabetes.

Moreover, you should never rely on a single fruit for complete nutrition. If you like to eat bananas, keep its portion size moderate so you have plenty of room to eat other fruits and veggies for a nutritionally balanced meal. 

The bottom line 

Moderation is the key. Eating 1-2 bananas per day should provide you with enough nutrients that you need from this fruit. For a healthy body and mind, you should turn to other nutrient-dense fruits and vegetables. Opting for a moderate intake of food helps prevent unhealthy weight gain and nutritional deficiencies.
