An international team of scientists headed from the University of Santiago de Compostela ensures that reading the labels on food products is linked to obesity prevention, especially in women. According to the study which used data from the USA, female consumers who consult food labels weigh nearly 4 kilograms less.

Along with the Universities of Tennessee, Arkansas (USA) and the Norwegian Institute for Agricultural Finance Research, the University of Santiago de Compostela has participated in a study on the relationship between reading the food label and obesity.

The results indicated that the body mass index of those consumers who read that label is 1.49 points lower than those who never consider such information when doing their food shopping. This translates as a reduction of 3.91 kg for an American woman measuring 1.62 cm and weighing 74 kg.

The data was taken from the annual National (NHIS) performed by the U.S. (CDC - http://www.cdc.gov/nchs/nhis.htm). Some 25,640 observations were collected on health and eating and . These included various questions on whether participants read the nutritional information in supermarkets and how often.

"First we analysed which was the profile of those who read the nutritional label when purchasing foods, and then we moved on to the relationship with their weight," as explained to SINC by María Loureiro, lead author of the study published in the 'Agricultural Economics' journal.

"Obesity is one of the most serious health problems in modern day USA," outlines the researcher. "The number of overweight or has risen over the years. From 2009 to 2010, more than a third (nearly 37%) of the in this country were obese and in children and adolescents this figure rises to 17%.

In terms of distribution, the highest was recorded amongst the non-Latin black population (49.5%), Mexican Americans (40.4%), Latins (39.1%) and the non-Latin white population (34.3%), according to 2010 CDC data.

Greater effect on urban white women

The team found very significant differences between consumers that read labels and those that do not. On the one hand, the study shows that the smoking population pays much less attention to this information. According to the researcher, "their lifestyle involves less healthy habits and as a consequence, it could be the case that they are not so worried about the nutritional content of the food they eat, according to our results."

Furthermore, the city-dwelling population (49% of the sample) takes nutritional information into account the most. This is also the case for those with high school education (40% of those surveyed) and universities studies (17% of the total sample).

According to sex, 58% of men either habitually or always read the information contained within nutritional labels. However, this figure stands at 74% for women.

"In general, the associated impact is higher amongst women than men," adds the researcher. On average, women who read the have a of 1.48 points lower, whereas this difference is just 0.12 points in men.

The study also touches on significant ethnic differences. In this sense, the white female consumers see the greatest reduction in the of around 1.76 points.

"We know that this information can be used as a mechanism to prevent obesity. We have seen that those who read 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," concludes Loureiro.
