Organic food

What the organic label means, what the evidence says about health and nutrition, and how to shop for it sensibly.

Organic food is grown and produced under rules that limit synthetic chemicals and require farming practices meant to protect soil, water and animal welfare. Many people buy it because they believe it is healthier, better for the environment or tastes better. Some of those beliefs are well supported, others less so. Here is what the label actually means and what the evidence shows.

What does organic mean?

In the United States, "organic" is a legal term regulated by the US Department of Agriculture (USDA). To be sold as organic, food must come from a certified operation that follows the National Organic Program's standards. In broad terms:

  • Crops are grown without most synthetic pesticides and synthetic fertilizers, without genetically engineered seeds, and without sewage sludge or irradiation. Farmers rely on crop rotation, compost, cover crops and natural pest control. Some pesticides are allowed, mostly from natural sources, along with a short list of approved synthetic substances.
  • Animals raised for organic meat, milk and eggs must be fed organic feed, have access to the outdoors, and cannot be given antibiotics or growth hormones.
  • Processed foods cannot contain artificial preservatives, colors or flavors, and must be made mostly from organic ingredients.

Other countries, including Canada and the members of the European Union, have their own organic standards, which are broadly similar.

Reading the label

The USDA organic seal can appear on products in the first two of these categories:

  • 100% organic: every ingredient is organic.
  • Organic: at least 95% of the ingredients are organic.
  • Made with organic ingredients: at least 70% organic ingredients. These products can list the organic ingredients on the front but cannot use the seal.

"Natural" is not the same as organic. In the United States, "natural" has no strict legal definition for most foods and does not mean the food was grown without pesticides. Labels such as "free-range" and "hormone-free" also have their own, narrower meanings.

Is organic food more nutritious?

Not by much, as far as the evidence shows. A large 2012 review by researchers at Stanford University looked at more than 200 studies and found little evidence that organic foods are significantly more nutritious than conventional ones. Later studies have reported some differences, such as slightly higher levels of certain antioxidants in some organic crops and more omega-3 fatty acids in organic milk, but the differences are generally small and vary with the farm, the season and the variety.

For your health, eating plenty of fruit, vegetables, whole grains and legumes matters far more than whether they are organic or conventional.

Pesticides, antibiotics and hormones

The clearest difference is in pesticide residues. The Stanford review found that organic produce was about 30% less likely to contain detectable pesticide residues than conventional produce. However, residues on conventional produce were usually within the safety limits set by regulators, and organic produce is not always residue-free.

The same review found that conventional chicken and pork were more likely to carry bacteria resistant to several antibiotics. This is part of a wider public health concern about antibiotic use in farming, which organic rules address by banning it.

Whatever you buy, wash fruit and vegetables under running water before eating them. It removes dirt, bacteria and some surface residues.

Environmental and ethical considerations

Organic farming generally uses fewer synthetic chemicals and puts more emphasis on soil health, and organic farms often support more wildlife and plant diversity. On the other hand, organic farms usually produce less food per acre, so producing the same amount can take more land. Whether organic is better for the planet overall depends on the crop, the farm and what is being measured.

Organic standards also set rules for animal welfare, including outdoor access and organic feed, which matter to many shoppers.

Shopping for organic food

Organic food usually costs more, because it takes more work and often produces lower yields. If you want to buy some organic food but can't buy everything organic, a few approaches help:

  • Prioritize the foods you eat most often, especially fruit and vegetables eaten with their skin.
  • Shop in season, and look at farmers markets, where you can ask growers directly how they farm. Some small farms follow organic methods without paying for certification.
  • Compare store brands, frozen organic fruit and vegetables, and bulk dried goods such as beans, rice and oats, which are often cheaper.
  • Remember that organic cookies, chips and soda are still cookies, chips and soda. The label tells you how the ingredients were grown, not whether the food is healthy.

Frequently asked questions

Is eating organic really better for you?

Organic food reduces your exposure to pesticide residues, but there is little evidence that it is more nutritious. Eating plenty of fruit and vegetables, organic or not, is what matters most.

What are 100% organic foods?

Foods labeled "100% organic" contain only organic ingredients and can carry the USDA organic seal.

Does organic food taste better?

Taste depends mostly on the variety, freshness and ripeness of the food. Many people find locally grown, in-season produce tastes better, whether or not it is organic.
