Hi, in January Elizabeth posted something about homocysteine and it's dangers. Homocysteine is made by the body in the process of converting methionine to the really needed cysteine. So I had the idea to scan the database for food items *already* high in cyysteine. (my post describing this idea http://maelstrom.stjohns.edu/CGI/wa.exe?A2=ind0301&L=paleofood&P=3404 ) Now I've made a query indicating the ratio of cysteine to methionine. If that's a theeory, then eating much high cysteine food items would lower homocysteine hence be beneficial for IHD (as an example). Many proteins have 1:1 equal of both. (column ratiocyst2met). Some have much more cy some much more met. Lentils and almonds, oats and hazel are relative high in cysteine. (ratio 1.5:1) Pumpkin seeds, rice, brazils, salmon,milk, beef and various meats are at 0.5:1 One of the best meats: pork kidney (1:1) and beef lungs (0.77:1). Here's the table: http://www.geocities.com/paleolix/CYT_PROTEIN_RATIO.html Interesting is the column ratiocyst2met (sorted) or cystein per protein. High values should be beneficial. I selected again my whole food items but only those with > 2g protein. Does anybody know his or her homocystein test value? And would like to test if some time with high cystein-foods might lower the homocystein results? Preferrably with a protein intake of less than double or 3-fold the RDA (less than 100 or 150 g protein or 500g-750g meat per day). Because in 3-fold RDA even low percents of cysteine would result in high enough cysteine intake. regards Amadeus
