Carbohydrates are one of the main types of nutrients our bodies need for energy. They are found in foods like bread, rice, pasta, fruits, and vegetables. When we eat carbohydrates, our bodies break them down into glucose, which is a type of sugar that provides fuel for our cells. There are two main types of carbohydrates: simple and complex. Simple carbohydrates, like those in candy and soda, provide quick energy but can lead to crashes. Complex carbohydrates, found in whole grains and legumes, offer longer-lasting energy and are often packed with fiber, which is good for digestion and overall health.
