A Roy Morgan Single Source survey has found that four per cent of Australians aged 18+ were lactose intolerant in the year to September 2015, compared with 2.8 per cent in the year September 2011. The number of men who are lactose intolerant has risen by just 3,000 to 1.7 per cent over this period, but the number of women has risen from 3.8 per cent to 6.2 per cent. The survey also shows that women aged 25-34 have the nation’s highest incidence of lactose intolerance (8.2 per cent), followed by women from the 35-49 age bracket (6.9 per cent).
