A study in "Climate Change" concluded "if ... average diets among UK adults conformed to WHO recommendations, their associated GHG emissions would be reduced by 17%. Further GHG emission reductions of around 40% could be achieved by making realistic modifications to diets so that they contain fewer animal products and processed snacks and more fruit, vegetables and cereals." A study in "The Lancet" estimated that the "30% reduction in livestock production" by 2030 required to meet the UK Committee on Climate Change's agricultural would also result in a roughly 15% decrease in ischaemic heart disease.
