"I love Justin's nut butter packets!" said Allison Childress, PhD, RDN, CSSD. "They are so easy to tote around, and you can leave them in your car, gym bag, or purse because they aren't susceptible to heat or cold. If you are trying to increase your consumption of healthy fats, these packets are the way to go!" Buy Justin's Honey Peanut Butter Packs ($7 for a pack of 10) on Amazon.
