Is Organic Meat Better?

Several recent scientific reviews have examined the nutritional differences between organic and conventional meat. Read on to learn what the researchers found, if organic meat is really better, and what other factors you should consider when buying your next steak dinner.

U.S. organic food sales have grown from $1 billion in 1990 to $31.5 billion in 2011 (1), and the demand for organic meat products has steadily increased over the last two decades. Most consumers cite an improved nutrient profile as their primary reason for buying organic (2). But is organic meat really better for us, nutritionally speaking? In this article, I’ll discuss the major differences between organic and conventional meat so that you can make an informed assessment of your meat purchases.

What is organic meat?

Before we dive into the nutritional differences, it’s important that we define what organic meat actually is. The United States Department of Agriculture (USDA) organic livestock conditions require that animals must be given year-round access to the outdoors, except in inclement weather. They must be managed without antibiotics (except in cases of illness), added growth hormones, or prohibited feed ingredients like animal byproducts, urea, and arsenic compounds.

Organic livestock must be raised on certified organic land meeting organic crop production standards and any feed must be 100 percent certified organic. Organic ruminants—such as cattle, sheep, and goats—must have free access to organic pasture for the entire grazing season, and 30 percent of their diet must come from organic pasture. Organic practices help to support animal health and are also markedly better from an environmental perspective (3).

Now that we’ve got a basic understanding of what the “organic” label actually means, let’s dive into the nutrition research.

Organic vs. conventional: fatty acid profile

Fatty acids are essential to health and are one of the key areas where organic and conventional meats differ. Two recently published meta-analyses assessed the differences in fatty acid composition between organic and conventionally raised meat and dairy products. We’ll look at the findings of each in more detail.

Meat: The amount of saturated fat was similar in organic and conventional meat, while monounsaturated fats were slightly lower in organic meats. Omega-3 polyunsaturated fatty acids were 47 percent higher in organic meat (4). Omega-3 fatty acids reduce inflammation and have been shown to be protective against cardiovascular disease and cognitive decline (5).

Dairy: The amount of saturated, monounsaturated, and total polyunsaturated fatty acids was similar in organic and conventional milk. Organic milk had 69 percent higher alpha-lipoic acid (ALA) than conventional milk. ALA is known to reduce levels of LDL cholesterol and enhance its clearance from the bloodstream (6). Organic milk also had 41 percent higher conjugated linoleic acid (CLA) and 57 percent higher omega-3 fatty acids.

So what about the organic method is driving this difference? The authors suggest that the pasture-based diets prescribed under organic farming standards are the primary reason for differences in fat deposition in the meat. This is consistent with differences seen between grain-fed and grass-fed animals, as we’ll come back to later on.
