Children with transient vision loss are less likely to have an ischemic cause for their symptoms and are more likely to have a benign disorder. In some children, a cause for the visual disturbance cannot be identified, and the symptoms remain medically unexplained.
There are three main types of carbohydrates, which are sugars, starches and fibre. Carbohydrates contain about 4 calories per gram. The main function of carbohydrates is to provide your body with fuel and energy that is required to carry out daily activities and exercise. When carbohydrates are in our body, they are being broken down and used as energy.
Your body looks at carbohydrates as fuel, so one of the main functions of carbohydrates is supplying energy to the body. Your brain is particularly in need of the simple carbohydrate glucose as an energy source. So supplying energy to the brain is another important function. We also see that having enough carbs for energy can prevent the breakdown of proteins for energy.
