Explanation: 

Detailed explanation-1: -Carbohydrates are the body’s main fuel source. During digestion, sugars and starches are broken down into simple sugars. They’re then absorbed into the bloodstream, where they’re known as blood sugar (blood glucose). From there, glucose enters the body’s cells with the help of insulin.

Detailed explanation-2: -Alongside fat and protein, carbohydrates are one of the three macronutrients in our diet with their main function being to provide energy to the body. They occur in many different forms, like sugars and dietary fibre, and in many different foods, such as whole grains, fruit and vegetables.

Detailed explanation-3: -Protein is an important part of a healthy diet. Proteins are made up of chemical ‘building blocks’ called amino acids. Your body uses amino acids to build and repair muscles and bones and to make hormones and enzymes. They can also be used as an energy source.

Detailed explanation-4: -Glucose (breakdown of most carbohydrates) is what our brain utilizes for energy. Fiber (source of carbohydrate) plays an important role in digestive health. Your brain and gut communicate – the brain is part of the control system for the gut. More items •25-Feb-2020
