The body can utilise three forms of nutrient to produce energy, they are carbohydrate, fat and protein. Carbohydrates can consist of simple sugars such as glucose (found in manufactured food) or complex carbohydrates such as starches, fibre, etc (root vegetables). Before carbohydrates can be used as food they all have to be broken down into glucose. All carbohydrates should be seen in the simplest of terms, they all become glucose once they are eaten. Glucose requires insulin for the body to be able use it. It can be used immediately for instant energy or stored in the form of glycogen in the liver and muscles. Excess glucose is converted to triglycerides (a fat) which ends up as body fat and in the liver, pancreas and eventually in arteries causing disease. High levels of glucose and insulin are thought to be involved in the increased production of beta amyloid, a protein that leads to Alzheimer’s dementia. Carbohydrates are not essential for life as we are able to thrive eating saturated fats.
