A new cookbook offers guidance and recipes for maximizing gastrointestinal health. Cooking for your body can mean avoiding some foods and adding others. It hinges on ingredients, and having a diverse diet. "Cook for Your Gut Health," is a new cookbook produced by America's Test Kitchen with dietician and nutritionist Alicia A. Romano ($29.99). Dan Zuccarello, America's Test Kitchen's executive food editor, discussed the new book during a recent interview. His team publishes 17 cookbooks a year, regularly working on two books at the same time. The topics are specific to the needs of their readership and current trends, he said. Gut health is a subject relatable to a wide swath of the public who suffer from bloating and gas and other digestive issues including irritable bowel syndrome, IBS.
