When 24-year-old Katlin Smith developed aches and pains, her doctors could provide no answers. After a friend reported benefits with an elimination diet, Katlin decided to try Paleo. So impressed was she with the efficacy of the diet at relieving her symptoms that she quit her job in a Big 8 accounting firm, and started a business making Paleo products--Simple Mills. After much trial and error in her test kitchen, she discovered ways to combine Paleo-compliant ingredients like almond flour that are delicious as well as wholesome. After just a few years, her company has become one of the fastest-growing natural products manufacturers in the country. She makes crackers, cookies, cake and bread mixes, and frostings--all free of preservatives, GMOs, emulsifiers, and 6 of the 8 most common food allergens. Her products have received multiple awards, and Smith was recently named to the Forbes 30 Under 30 Class of 2017.
