A few weeks ago, someone tweeted at me, "Is it possible to develop an intolerance to dairy after being vegan for a short time?" Going vegan (or dairy-free) doesn't make you lactose intolerant, yet many people find after removing dairy from their diet, they can no longer tolerate it. Why? People who are lactose intolerant can't digest lactose, the sugar found in milk. Lactase, the enzyme that helps humans digest lactose stops being produced when the person is between the ages of 2 and 5. Without lactase to break down the sugar, it goes on to the colon undigested where it ferments, producing gas that causes cramping, bloating, nausea, flatulence and diarrhea.
