I caught on video news this AM that due to last summers weather extremes, the price of peanut butter is set for a dramatic rise with the Peter Pan brand to start the parade today. I would guess that it has probably taken place over night.
Peanut butter has been a protein source for low income families and seniors for a long time. Also, a healthy lunch item for school children. I personally use it as a buffer against glucose spikes in the AM. I may go back to a whey additive for the buffer. It makes my breakfast gruel taste funny but it works.
I suspect we have more price increases yet to come.
