If it is preparaed correctly POstum is a delicious cereal based hot drink. It stands alone and in no way should be confused as a substitute for coffee. (My opinion. I am 77yrs old and entitled to an opinion)
Postum is delicious????? I can't gag it down. When I read on this board, several years ago that Postum was going off the market, my DH rushed out and went to all the local stores (within a 60 mile radius) and bought all the Postum they had. Because they were on close-out, he only paid a dollar or 2 for each. We have enough to last as long as he lives. It was quite a bargan if you don't count the fuel it took to round them up.
Actually, the health benefits of tea and coffee are such that not drinking them may cost you your life. I am referring to the fact that it reduces one fatal type of prostate cancer up to 80%, may reduce adult onset diabetes up to 50%, reduce depression, permit you to drive more safely, and delay Alzheimers. I don't know of any kosher rule which actually harms you as does the WoW.
