What is Organic?
“Organic” means the food was produced with agricultural methods that facilitate cycling of resources, promote ecological balance, and maintain biodiversity. Organic production does NOT involve pesticides, synthetic fertilizers, sewage sludge, irradiation, or genetic engineering.
There are a few ways organic foods can be labeled. Foods that are made with all organic ingredients can use the USDA Certified Organic Seal And can claim “100% organic” on the front label. Foods made with 95% of organic ingredients – by weight, excluding water and salt – can use the claim “organic” and also display this seal. Foods that are labeled “made with organic ingredients” contain at least 70% organic ingredients. The can be listed on the font label and in the ingredients list but the organic seal cannot be displayed on the product. The below image provides a quick glance at organic labeling.
According to a review conducted in Brazil, some organic foods had slightly better nutritional content and durability, but more studies are needed to determine whether or not they are actually superior. (Sousa AA, Azevedo Ed, Lima EE, Silva AP. Organic foods and human health: a study of controversies. Rev Panam Salud Publica. 2012 Jun;31(6):513-7.)
Another review, this time looking at the safety of organic versus conventional foods, found that there is not strong evidence that organic foods are more nutritious compared to conventional ones, but they may reduce the exposure to pesticides and antibiotic resistant bacteria. (Smith-Spangler C, et al. Are organic foods safer or healthier than conventional alternatives?: a systematic review. Ann Intern Med. 2012 Sep 4;157(5):348-66)
I also found a review conducted in Germany that focused on organic versus conventional dairy. The study added data from the last three years to an existing pool of data and found that organic dairy products are higher in protein and omega-3 fatty acids and have a higher omega 3 to omega 6 fatty acid ratio than those of conventional types. Typically, the Western diet is high in omega 6 fats and low in omega 3 fats, but a higher omega 3 to omega 6 ratio is thought to reduce inflammation and risk of heart disease. The authors suspect that these results are due to the differences in the way organic and conventional dairy cows are fed. (Palupi E, Jayanegara A, Ploeger A, Kahl J. Comparison of nutritional quality between conventional and organic dairy products: a meta-analysis. J Sci Food Agric. 2012 Mar 19. doi: 10.1002/jsfa.5639. [Epub ahead of print])
A study on the environmental impact of organic farming found that organic systems had lower nutrient losses and energy requirements but had higher nitrous oxide emissions and required more land than conventional farming. Most studies did show less environmental impact from organic farming than conventional farming.(Tuomisto HL, Hodge ID, Riordan P, Macdonald DW. Does organic farming reduce environmental impacts? – A meta-analysis of European research. J Environ Manage. 2012 Sep 1;112C:309-320. [Epub ahead of print)
And finally, there is the now infamous Stanford Study. Published a few weeks ago, this review of studies on conventional versus organic fruits and vegetables found that organic produce wasn’t overall any more nutritious or any less of a health risk than conventional produce, although it did lower the risk of pesticide exposure.(Smith-Spangler C, Brandeau ML, Hunter GE, Bavinger JC, Pearson M, Eschbach PJ, Sundaram V, Liu H, Schirmer P, Stave C, Olkin I, Bravata DM. Are organic foods safer or healthier than conventional alternatives?: a systematic review. Ann Intern Med. 2012 Sep 4;157(5):348-66.)
Basically, what all this tells me is that organic produce has its benefits – like that it is more sustainable, better for the environment, and contains less pesticide residue. But this doesn’t mean eating conventionally grown foods are bad for you. While a conventional apple may have more pesticide residue than an organic one, it is still far below the level that the Environmental Protection Agency deems unsafe.
Focus on eating more fresh or frozen fruits and vegetables overall, no matter how they are grown. If you can afford to buy every single item organic, and are inclined to do so, then obviously this is ideal. BUT, if you’re on a tight budget, don’t lose sleep over it. The health benefits of eating more fruits and veggies far outweighs the risks brought on by the amount of pesticide or bacteria on the item. Especially if you wash it well.
Now, if you want to start buying some organic foods, I suggest starting with milk and dairy, since research HAS shown organic dairy to be nutritionally superior. Next, move on to the fruits and vegetables known as the “dirty dozen”, which are basically items with either thin or edible skins that are most likely to transmit any pesticides on to you. These are:
- Sweet Bell Peppers
Finally, I’d like to make one last point about organic foods. A lot of people associate the word “organic” with “healthy”, but this is NOT always the case. For example, organic cane sugar is no better for you than normal cane sugar, and a brownie made with organic sugars and nuts will add just as many calories and sugars as a brownie made with conventional items. When you choose an organic item, except for dairy, it should be because you want to choose something produced with a lower environmental impact and less pesticides, not because you are looking for a “healthier” or “more nutritious” food.
What’s your take on organic foods? Must have, or waste of money?
