70% of the world population is also lactose intollerent, which means they CANNOT digest it. If you use lactaid , then the slow digesting carb becomes a blood sugar raising bomb. Lactose is glucose + galactose bound together. This means that it's a disaccharaide. 2 simple sugars bound together. The enzyme in your stomach (for the 30% that produce this enzyme) called lactase is used to break the bond between the 2 simple sugars. Once broken , the 2 simple sugars will have a high insulin response. So using milk with lactaid in conjunction with r+ala makes sense.
