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?

Due to the high-fat nature of a ketogenic or LCHF diet they have been considered to be potentially hazardous for those with cardiovascular disease (CVD).
Publicly available information (i.e. position statements and general patient information) from public health groups often include cautions against the use of VLCDs due to these perceived risks. Diabetes New Zealand states in their article on Low Carbohydrate Diets that “Eating more protein and fat may increase your risk of heart disease in the long term.” (1).
So are ketogenic diets dangerous for heart health?

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.

Caveat emptor….let the patient beware
The honorific ‘Doctor’ carries with it a certain mystique. We tend to pay more attention to the opinion of someone with a doctorate…and rightly so. The years of study, research and application required to earn a doctorate deserve a certain level of respect, and anyone that has embarked on post-graduate study knows that it’s not an easy journey!
It is exactly this legitimacy that has promoted the drive towards ‘doctorisation’ in many professions, and has also spurred the proliferation of diploma mills and unaccredited colleges.

It's a food fight.
The time has finally come where a deep and important line needs to be drawn in the sand. No more throwing bad science and bad advice around. Stop!
The “food pyramid” guidelines are still alive (and well?) in New Zealand (see here). They are outdated, old school and quite simply wrong. Recently they were up for review…
Unfortunately, they came back more or less the same – saturated fat, and fat are bad for us ….blah blah blah.
