Not necessarily. Many individuals who have difficulty digesting lactose (milk’s sugar) can consume a glass or two of milk a day with meals with few, if any, symptoms. Smaller portions of milk (4 oz) consumed more often may be better tolerated. Lactose-reduced or lactose-free milks are also an option. Lactose-reduced milk contains about 70% less lactose than regular milk. Lactose-free milk is 100% lactose reduced.
