I think there's a basic failure to understand the nature of the flaxseed/thyroid connection. Basically, raw flaxseeds contain cyanogenic glycosides which - if you eat more than 4-5 Tbsp daily, can inhibit thyroid function. There's an easy solution: Toast the flaxseeds (heat destroys the glycosides).

Thus, flaxmeal made from toasted flaxseeds poses no thyroid threat. FYI, other foods that contain cyanogenic glycosides include almonds, lima beans, cassava, prunes, bamboo shoots.

Hope this helps
