foods containing methylsulfonylmethane
Most fruits also contain MSM, but no sulfur from cysteine or methionine, because there is hardly any protein in fruits. MSM has also been found in tea, coffee, beer and port wines. It is not easy to determine sulfur content in foods because the amounts depend greatly on the quality of soil and farming practices.
Canned and cooked tomatoes will contain significantly less MSM per serving. Corn may contain as much as 0.11 ppm, or 0.11 milligram per liter, of MSM. That's less than foods like coffee, which has an MSM concentration of 1.6 ppm, and Swiss chard, with about 0.2 ppm, but more than alfalfa, which contains only 0.07 ppm. It does contain biotin, but not much: 0.06 microgram in a 1/2-cup serving of canned whole corn.
