Can Milk Be Bad For You?

Most People are Lactose Intolerant 1 of 8

Most people are lactose intolerant to some degree, meaning they don't produce enough or any of the enzyme lactase, which digests lactose, the sugar in milk. About 75 percent of people worldwide are lactose intolerant; and some groups, such as those of Asian descent, are afflicted even more at 90 percent.

Most people stop producing lactase as they age, evidence that we are not meant to drink milk beyond childhood. Those who are lactose intolerant can develop symptoms, such as:

  • nausea
  • bloating
  • cramps
  • gas
  • diarrhea
  • abdominal pain
