These foods are grown without fertilizers, pesticides, and other synthetic additives. But are they better for you?
Walk through any grocery store today, and you'll likely see more shelf space devoted to organics—foods that are grown without most synthetic fertilizers and pesticides, and animal products that are free of antibiotics and hormones. Demand for organic food is up, with sales reaching $35.9 billion in 2014. "I think people believe these foods are better for them, but we really don't know that they are,"
Is there a benefit?
While organic foods have fewer synthetic pesticides and fertilizers and are free of hormones and antibiotics, they don't appear to have a nutritional advantage over their conventional counterparts. "There've been a number of studies examining the macro- and micronutrient content, but whether organically or conventionally grown, the foods are really similar for vitamins, minerals, and carbohydrates," says McManus.
According to USDA data, organic foods have fewer pesticide residues than conventionally grown produce. But the amounts for both types of produce are within the level for safe consumption. And it's unclear if the pesticides used in organic farming are safer than nonsynthetic pesticides used in conventional farming. "The verdict is still out about pesticides and fertilizers as far as the long-term impact on health. There are so many other variables in the environment. It's hard to say it's the pesticide on the peach that was the primary cause of a health-related issue," says McManus.
Similarly, we don't have enough information yet to know if the lack of hormones and antibiotics in organic animal products makes them healthier than conventional animal products.
