aChange observed when comparing consumption of foods high in salt/sugar with substitutes lower in salt/sugar. bTotal change in environmental impacts when aggregating daily impacts over 1 y and for a UK adult (males + females) population of 53.2 million. CO2eq = carbon dioxide equivalents (climate change impact); PO4eq = phosphate equivalents (eutrophication potential); SO2eq = sulphur dioxide equivalents (acidification); Mt = mega tonnes; ha = hectares
