Some foods have always been championed as good for the gut. Take yogurt, for example. It contains live "good" bacteria, a.k.a. probiotics, which aid in boosting the immune system, ameliorating gastrointestinal conditions, and making you feel fuller. Now a new study says that even coffee and wine—two drinks that seem like highly acidic choices for sensitive stomachs—may actually be good for gut bacteria.
According to Dr. Jingyuan Fu's research at the University of Groningen in the Netherlands, it's not that our bodies need certain microbes in the gut; we need a good diversity of microbes. Fruit, vegetables, tea, buttermilk, yogurt, coffee, and wine are all recommended, while sugary sodas, savory snacks, artificial sweeteners, high-fat whole milk, and foods rich in simple carbohydrates are discouraged because they reduce bacterial diversity.
