Nachos, chocolate, frozen yogurt, smoothies and many more delicious foods have one thing in common: they traditionally contain milk. The trouble is, not everyone can absorb and tolerate milk in the same way because many people are affected by lactose malabsorption, which in turn can lead to lactose intolerance. Lactose intolerance simply means that a person actually presents digestive symptoms based on this inability to break down Lactose, a sugar naturally derived in milk and milk products.
