There are Luna Snack Bars that come in various flavors.
However, some say if you are a man, you should ‘be careful’ eating a lot of these over a long period of time, because the bars are meant for women. The product page says ‘there is no truth to the rumor that Luna Bars will cause a man to grow breasts. They contain no estrogen or other hormones!”
They wouldn't have to deny it if it wasn't true.
The protein in Luna bars comes from soy. Soy has multiple estrogenic and steroidal compounds in it (but not actual “estrogen”). Japanese men who ate more soybeans were shown to have a higher rate of severe mental disease. Women do not get this problem, but can have greater feminine characteristics, and can start puberty earlier.
My wife and I stay away from soy products.
