Yeah, I have a 15YO son allergic to peanuts and tree nuts.
He just went on a week long Appalachian Trail trip were most of his peers spend the day slowly fueling on peanut laden GORP. His mix was dark chocolate M&M's, raisins and quality beef jerkey. Hard to trust ANY of the energy bars, as even the ones without an explicit nut ingredient are generally labeled as made in a facility that processes nuts.
As previously noted, fig bars are great. Even the son, who is somewhat of a picky eater, likes 'em.
