Earlier this week I considered whether there should be a tax on unhealthy foods.
I concluded that a tax on our saltiest, fattiest foods and cutting the price of fruit and vegetables would encourage people to choose healthy options.
Some disagree but it is clear, in my view, that some drastic action is required to tackle growing obesity rates in this country.
That's why it is good to see the Ministry of Health instructing all health boards to stop sales of sugar-sweetened beverages to reduce obesity.
Thirty per cent of New Zealand adults are obese - the third-highest rate in the developed world - and 10 per cent of children.
