Carbohydrates, Why are carbohydrates so important?Aliza
protein is made up of amino acids, carbohydrates consist of building blocks called ‘saccharides’ or ‘sugars’. Glucose, a common example of the simplest type of sugar, is a monosaccharide, together with fructose, found in fruit. Two monosaccharides joined together are called disaccharides, the most common being sucrose or ‘white cane sugar’ as we know it. Another example is lactose, found in milk. When large numbers of saccharides are joined together, they form polysaccharides and are found the foods we commonly think of as ‘carbohydrates’, e.g. bread, potatoes and pasta.
Dietary fibre belongs to the carbohydrate group but is not digestible. Fibre has important roles in helping you feel full after a meal, in adding bulk to stools and preventing constipation and generally for gut health. Fibre is only found in plant-based foods such as whole grains, lentils and fruit and vegetables.
