Study – Discount healthy foods to improve diets
According to a new research carried out by the RAND Corporation in South Africa (attached), reducing the cost of healthy foods in supermarkets and retail outlets increases the amount of healthy fruits, vegetables and whole grains that people eat while lowering consumption of foods with low nutritional value (rather than increasing the cost of unhealthy foods). Writing in the American Journal of Preventive Medicine, the researchers found that a rebate of 25% increased the ratio of healthy to total food purchased by 9.3%. In addition, the rebate increased the ratio of fruit and vegetables to total food purchases by 8.5%, and decreased the ratio of less-desirable food to total food purchases by 7.2%. The authors also noted that the effects of the price subsidies appeared stable over time, while the 25% rebate had consistently greater impact than the smaller rebate. Based on self-report, individuals who received a 25 percent rebate consumed an additional half-serving of fruits and vegetables each day, and were also less likely to consume fast food, foods high in sugar and salt, fried foods and processed meats. However, there was no evidence that the rebate program reduced rates of obesity or that fewer participants were overweight, said the research team.
