Nutrition Dictionary

  • Insoluble Fibre

    Insoluble fibre is a type of dietary fibre found in cereals, the outer skins of some fruit and vegetables, nuts, seeds and often in high fibre breads. Insoluble fibre absorbs water in the large intestine which helps to soften bowel contents and promote regularity.

  • Insulin

    Insulin is a hormone that is produced by the pancreas in response to the food we eat. Insulin’s main role is to take glucose from the blood and move it into the body’s cells so that the cells can use the glucose for energy.

  • Iron

    Iron is a mineral that is used by the body to make haemoglobin, the part of the red blood cell that transports oxygen. Iron-containing foods include red meat, poultry, legumes, green leafy vegetables and whole grain breads and cereals. A lack of iron in the diet or poor absorption of iron can lead to iron deficiency anaemia.
