One of the Cook's bigges resort owners is backing a call from health experts for a "junk food tax". Tata Crocombe (right), the managing director of The Rarotongan, wants to see price rises on foods with high sugar, salt or saturated fat to force people to buy healthier. In his words "we should be taxing the hell out of bad food products". He said if Cook Islanders went back to the diets of their grandparents - fish, lots of vegetables, some taro, maniota, kumara and rukau - they'd be 70 per cent of the way back to good health. And if they exercised, and they'd be 90 per cent there.
