High levels of methionine can be found in eggs, meat, and fish; sesame seeds, Brazil nuts, and some other plant seeds; and [[cereal]] grains. Most fruits and vegetables contain very little. Most [[legume]]s, though protein dense, are low in methionine. Proteins without adequate methionine are not considered to be [[complete protein]]s.<ref>{{Cite journal |vauthors=Finkelstein JD |date=May 1990 |title=Methionine metabolism in mammals |journal=The Journal of Nutritional Biochemistry |volume=1 |issue=5 |pages=228–237 |doi=10.1016/0955-2863(90)90070-2 |pmid=15539209|s2cid=32264340 }}</ref> For that reason, racemic methionine is sometimes added as an ingredient to [[pet food]]s.<ref>{{Cite book |last=Palika |first=Liz |title=The Consumer's Guide to Dog Food: What's in Dog Food, Why It's There and How to Choose the Best Food for Your Dog |date=1996 |publisher=Howell Book House |isbn=978-0-87605-467-3 |location=New York |name-list-style=vanc}}</ref>
