Using cheese as a reference point, the high fat with calcium is probably allowed because of the D content. That's pretty high fat... (makes dairy look appealing) If one has a high fat with a calcium food and makes sure to include the D, then what?. I think it's safe to say that sunlight doesn't apply here? Oh this is interesting stuff..... Oliva ----- Original Message ----- From: "Todd Moody" <[log in to unmask]> Unfortunately I don't know how to estimate the amounts. The point is only that fat, like phytic acid, acts as an antinutrient under some conditions. My original source was not a text but a biologist that I work with.
