Live longer, enhance fertility and increase stress resistance: Eat organic foods
Health food advocates have long claimed that organic foods are better for your health because they have more nutrients and fewer pesticides than non organic or genetically modified grown foods. On the other hand, the USDA and agribusiness tend to claim that organically grown foods have no additional benefits. Until now, much of the published research appeared inconclusive and meta-analysis appeared to indicate that there are no health benefits from organic as compared to non organic foods although organic foods did reduce eczema in infants (Dangour et al, 2010).
Food studies that have demonstrated no benefits of organic farmed foods as compared to non-organic or genetically modified crops should be viewed with skepticism since many of these studies have been funded directly or indirectly by agribusiness. On the other hand, independently funded research studies have tended to demonstrate that organic foods are more beneficial than non-organic foods. Sadly, the United States Department of Agriculture (USDA) and agribusiness are highly interdependent as the USDA both regulates and promotes agricultural products.
Historically, most nutritional studies have investigated the nutritional difference or pesticide residue between organic and non-organically farmed. Many studies have shown that organic grown foods have significantly lower pesticide residues than non organic foods (Baker et al, 2002; Luc, 2006). Even though agribusiness and the USDA tend to state that the pesticide residues left in or on the food are safe and non-toxic and have no health consequences, I have my doubts. Human beings accumulate pesticides just like tuna fish accumulates mercury—frequent ingesting of very low levels of pesticides residue may result in long term harmful effects. One way to measure if there is an effect of organic, non organic or genetically modified grown foods or residual pesticides is to do a long term follow up and measure the impact over the lifespan of the organism. This is difficult with human beings; since, it would take 50 or more years to observe the long term effects. Nevertheless, the effects of organically grown foods versus non-organically grown foods upon lifespan, fertility and stress resistance has now been demonstrated with fruit flies.
