Sounds like the promos for lots of the overly expensive dehydrated powdered supps of veg!!
So, will have the very same quality issues.
Also, these are processed foods. Can not be sure that extra NPN did not find its way into them!!!
A few of their selections are combos of food that are usually at least average in quality. Those food combos have worked well for me purchased IF THE FOOD IS FRSH AND HOME-PREPARED.
Others contain at least one food variety that is typically so poor in quality from almost all commercial sources that it should only be eaten home-grown. So, HOW will the combo of poor quality, too much NPN help ANYONE???
