Reading food labels while doing grocery shopping has been linked to obesity prevention, especially in women.
That's according to a study by an international team of scientists from the University of Santiago de Compostela, reported by foodbev.com, who found that females who consult food labels before purchase weight nearly 4kg less than those who do not.
Furthermore, 58 per cent of men 'either habitually or always read' the information contained within nutritional labels. This figure stands at 74 per cent for women.
Other figures from the study show the city-dwelling population take nutritional information into account (49 per cent). Those with high school education (40 per cent) and those at university (17 per cent) also read labels.
Additionally, those who smoke pay much less attention to labels.
Lead researcher Professor Marma Loureiro, cited by dailymail.co.uk, commented on the figures: "We know that this information can be used as a mechanism to prevent obesity. We have seen that those who read food labels are those who live in urban areas, those with high school and high education.
"As we would hope therefore, campaigns and public policy can be designed to promote the use of nutritional labelling on menus at restaurants and other public establishments for the benefit of those who usually eat out," added Loureiro.
