My cousin is a nutritionist and lecturer, and he goes on and on sometimes about how deceptive "wheat bread" is, in that most stuff sold as "wheat bread" is not really significantly healthier than white bread, and that allowing producers to try to market their "wheat bread" as something somehow better than "white bread" in any health-related way is deceptive and damaging to America's health, overall, because it lulls us into a false sense of security.
Currently, he's recommending just one national brand of bread that meets his criteria: Food For Life's Ezekiel bread.
If that's not an option, he says that you buy bread for which "sprouted wheat" is the first ingredient... or at the very least, that "whole wheat" (not "whole wheat flour") is the first ingredient.
