With their healthful image, mushrooms are a smart choice for chips, especially crisp and flavorful ones that come in on-trend flavors. Those two aspects are likely to mitigate any potential ick factor, and the worldwide popularity of mushrooms is another asset. According to statistics reported by Food Navigator, the global mushroom market is projected to more than double from $34.1 billion in 2015 to $69.4 billion by 2024. Besides their adaptability to different dishes and flavors, mushrooms are considered a superfood because of their nutrient profile. They contain the soluble fiber beta glucan, which scientists say can help bolster the immune system. They have virtually no fat or cholesterol and contain B vitamins, as well as selenium and potassium. As an example of the shiitake's potential, Kellogg last fall invested through its VC arm in MycoTechnology, a Colorado firm making vegan mushroom-based protein.
