Corn is considered as a starchy vegetable as it contains a high amount of carbohydrates which provide you with short term and long term energy. They also ensure proper functioning of brain and nervous system. One cup of corn provides around 29 grams of carbs. This is particularly beneficial for athletes as they require more carbs to optimize exercise performance. Moreover, corn is a complex carb so it gets digested at a slow pace, thus providing you with balanced energy levels that are free of peaks and valleys. It is advisable to eat corn a couple of hours before exercising for lasting energy.
