Beauty starts from within, they say. Well, get ready, because gut health is set to be a major trend in 2018. Food and wellness experts claim that the good bacteria that lives in our digestive systems plays a role in our ability to absorb important vitamins and minerals, balancing our hormones and clearing out toxins. If the bacteria goes out of whack, or the bad kind is more present than the good, this can lead to all sorts of problems, such as a compromised immune system, poor digestion and even mental health concerns. In other words, it’s not just a stomach ache you should be worried about.
