Organic whole milk contains more omega-3 fatty acids than conventional whole milk, according to a study published in PLOS One. The research, funded mainly by the Organic Valley farm cooperative, analyzed 384 milk samples collected throughout the U.S. over an 18-month period. The organic milk had a 2.28 ratio of omega-6 to omega-3 fatty acids -- or 62% more omega-3 and 25% less omega-6 -- compared with conventional milk's 5.77 ratio, according to the findings.
