How Many Calories Does A Banana Have?

Nutritional Information For Bananas

October 17th, 2012

By , Clinial Nutrition Writer

There are 100 calories in a medium banana and 125 calories in a large banana. Bananas are primarily composed of carbohydrates (92%). Broken down further, bananas are 3% fat, 55% sugar, 12% fiber, 25% complex carb, and 5% protein. Of the sugar they contain, roughly 51% is glucose and 49% is fructose.

Bananas are significant sources of several vitamins and minerals, including vitamin C, vitamin B6, potassium, magnesium, and manganese. However, from when stacking nutrients against calories, bananas are not as nutrient-dense as other foods which contain higher levels of these vitamins and minerals and lower calories, such as chard and spinach.

One banana contains, on average, 7-8 grams of fructose. Fructose is found in most fruits and is not, by itself, harmful, but when consumed in large amounts it is converted easily into fat. Compared to other fruits, bananas contain more fructose and less nutrients, especially beneficial phytochemicals, and is not an ideal choice for fruit. In fact, bananas earned only a 35 out of a maximum of 1000 on a scale of nutrient density developed by Dr. Furhman, which is less than half what most fruits got!

Having a banana every now then is not a problem, but if bananas are always your go-to fruit of choice, you might want to consider finding a different fruit to begin snacking on! Organic berries are always a fantastic choice, and if you want to increase your daily fiber intake, finding fruits with edible skins will ensure you get some extra fiber in. Remember though, if you eat the skin, it's important to buy organic so you don't eat all the pesticides sprayed on the skin as well!

How Fructose Prevents Belly Fat From Being Burned

Of even more worry than glucose in the modern diet is fructose. Most refined sugars contain a significant portion of fructose in addition to glucose. Many people revile high-fructose corn syrup as being a great evil in the world of food, but the truth is that even regular table sugar is 50% fructose (the aforementioned high fructose corn syrup is 55% fructose, a scant 5% higher--realistically speaking, table sugar is just as bad).

Agave nectar is even worse, running as high as 85% fructose in some batches! As with fat, fructose is not truly the enemy here--overconsumption of that sugar is.

The issue with fructose is that our body cannot use it directly as energy, vastly preferring glucose as its sugar fuel source. While glucose will begin circulating in the blood almost instantly after absorption, providing energy to our brain, muscles, and other organs, fructose gets metabolized by the liver instead, first into glycogen (a form of short-term storage) if it is needed, and then into fat.

Key Point: If too much fructose is consumed at once, our liver is overloaded, and more fructose will end up as fat.

When we consume processed food, the sugar content is usually significantly higher than what is found in nature, and is released much faster (as a result of low to no-fiber content). The average can of soda contains more sugar than two apples, and the sugar it contains is completely absorbed by our small intestine within 5 minutes.

A small cake or cookie can be completely broken down and absorbed in twenty minutes once it enters the small intestine. Even if the food is low-fat, the end result is still a rise in free fatty acids in the blood, as the sugars get metabolized into fat to be stored!

Why You Must Avoid Processed Foods To Burn Belly Fat

To make matters worse, many processed foods tend to be high in both fat and sugar, a nightmare for insulin resistance. Now, free fatty acids are being elevated from two ends of the spectrum, and there is a good chance that much of the excess energy (especially from the fat) will be stored instead of burned, leading to obesity as well.

This extra weight will then play its own role in the formation of insulin resistance, creating a dangerous cycle.
