Abstract

Consumer demand for organic food is mostly based on the belief that organic products are healthier because they are less contaminated with pesticides. We explain why health benefits from a decreased exposure to pesticides through organic food consumption remain unsubstantiated. There is sufficient evidence to conclude that nonorganic food products contain higher levels of synthetic pesticides. However, a link between the consumption of an organic diet with health benefits is confounded by a number of lifestyle and demographic covariates. We recommend dietary intervention studies be conducted such as randomized double-blind placebo-controlled investigations to determine if a group of individuals consuming an organic wholefood diet or an equivalent nonorganic diet present any differences in health status.
