High cholesterol

High cholesterol levels are associated with increased risk of heart disease and stroke. Reducing saturated fat intake, increasing fibre intake and being more active can all help reduce blood cholesterol levels.


Iodine helps make the thyroid hormones which control the body’s metabolic rate.Iodine is a trace element found in seawater and some types of soil. Good food sources include sea fish and shellfish. Plant foods can also be a good source, depending on the iodine content of the soil. Adults need 0.14mg of iodine a day.


Dietary iron is found in two forms - haem iron (from animal sources) and non-haem iron (from plant sources). Haem iron is the most bioavailable form of iron. The main food sources are red meat, liver, offal, fortified cereals, shellfish, wholegrain breads, pasta and cereal, pulses and green leafy vegetables. Vitamin C will enhance iron absorption. Iron is involved in red blood cell formation, oxygen transport and utilisation.

A lack of dietary iron may result in iron deficiency anaemia. Loss of blood due to injury or large menstrual losses increases iron requirements in the short-term. The recommended intake is 8.7mg/day for men and 14.8mg/day for women.
