Grass-Fed Animal Products

Most conventional supermarket dairy and beef contain negligible amounts of CLA. Animals must be exclusively grass-fed for their entire lives for meaningful CLA content in their meat and dairy. Ruminants produce CLA by converting linoleic acid from grass through a digestive process; shifting to a grain diet disrupts this pathway. Farmers markets are more reliable than conventional grocery stores for verifying grass-fed sourcing. Even partial grain feeding during only the final months before slaughter is enough to negate the CLA advantage entirely.
