Adding to the all-bran one: the traditional forms of bran are oats and barley. This one is wheat. This year wheat crops have not been very good. They're selling you the extra roughage and waste now the grain itself isn't available. And claiming it's good.
Yay consumerism, bad science and big business!
I rarely talk to people about Paleo/Primal, but, when I do, it's when they're NOT complaining about their weight or health.
You see, I don't really "do" pity. And one thing I've learned about people is that they're more open to suggestion when they're happy and stable. When they complain they only ever want pity, not to be advised.
