OXFORD, England, May 18 (UPI) -- Taxes on unhealthy food might improve health, but the tax would need to be at least 20 percent to have a significant effect, British researchers said.
Oliver Mytton and colleagues at the University of Oxford in England said evidence suggests taxing a wide range of unhealthy foods or nutrients is likely to result in greater health benefits than narrow taxes, although the strongest evidence base is for a tax on sugary drinks.
