Yes, bananas contain glucose which the body turns into energy. Bananas also contain a natural form of sugar called glucose which is often used as a sugar substitute by those needing to watch their sugar intake. Bananas are a preferred food for bodybuilders because they contain potassium which helps muscles contract.
But there are lots of other foods that give energy. Here is a short list:
Pumpkin Seeds - contain magnesium which converts food into energy. Magnesium is also known to help prevent migraine headaches.
Watermelon - full of B-vitamins, potassium and fructose--all of which boost energy.
Apples - also have fructose, in addition to fiber and vitamin C.
Leafy Greens - eating a salad is great for energy. Leafy greens are full of vitamins C and A for energy and also contain a form of vitamin B called folate which is known to help with depression. Folate can be found in spinach, broccoli, asparagus, brussels sprouts and lettuce.
Nuts - contain lots of protein for energy. Nuts like walnuts, cashews, almonds and pecans are great foods for energy.
Eggs - contain protein, B-vitamins and iron and are a powerful source of energy.
Lean Meats - like skinless chicken and turkey also contain B-vitamins and protein for energy.
Red Bell Peppers - one red bell pepper alone contains 380 percent of daily recommended levels of vitamin C, and vitamin C helps fight fatigue.
Other foods known to increase energy include dark chocolate, which can increase blood flow to the brain for 2-3 hours, black or green tea which contains an amino acid called L-theanine that increases alertness (also contains caffeine), and good old coffee, probably one of the most commonly used beverages to increase energy and alertness.
So, before grabbing a pricey energy drink whose ingredients are not known and that can have bad side affects, grab a banana or any of a wide variety of foods that naturally and safely boost energy.
