US snacks maker Kind LLC has been one of the country's most successful challenger brands in recent years, with its products eating into the sales of larger, more-established competitors amid growing demand for simpler, less processed foods. Last year, the US Food and Drug Administration claimed Kind was breaching rules on content claims by putting the word 'healthy' on its bars, as the products contained higher-than-permitted levels of saturated fat, principally due to the nuts in the recipes. Kind changed its packaging but started work on challenging the FDA's decision. Earlier this month, after discussions with Kind, the FDA relented. Dean Best spoke to Kind CEO Lubetzky about the episode.
