You hear so much in the nutrition world about glycaemic index, insulin index and glycaemic load and how you should avoid particular foods that fit into certain categories. Just walk down the cereal isle in the supermarket and you will see an abundance of packaging boasting that this particular product is ‘low GI’ and therefore the healthy choice. With all this confusion about these different terms it’s worth having a think about what in fact they actually mean. Should we be putting a lifetime ban on foods that have a high glycaemic index and on the contrary; does a low glycaemic index food mean it is a great healthy option?

Dietary guidelines for health are still heavily weighted (excuse the pun!) in favour of high-carbohydrate diets.
Nutrient Reference Values (NRV) for New Zealand and Australia for example state that the diet should contain a minimum of 45% of its calories from carbohydrate (1) and New Zealand Heart Foundation position statements on carbohydrate (currently being updated) suggest a range of 55%-65% caloric intake should be obtained from carbohydrate along with reducing intake of total and saturated fat (2).
Why is this the case?

The New Zealand Heart Foundation state that the “Tick Programme helps New Zealanders make healthier food choices” but evidence would suggest that many of the foods that sport the Heart Foundation’s Tick are exactly the type of foods that do not support making of better health.
