When To Consume Sweet Corn?

Sweet corn is loaded with protein and releases ample energy. It contains a significant quantity of carbohydrates and fiber. It should be consumed at a time when the body’s energy demand is at its peak. The ideal time for consumption is during breakfast or lunch. When consumed early in the day, the body has enough time to digest and utilize the energy released by sweet corn. It also helps in avoiding bloating and flatulence which happens due to partial digestion of the food.

Overconsumption of sweet corn can lead to a number of adverse effects. Some of the common ones are:
