Organic VS Conventional
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.
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. 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.
