Lots of people will say they are lactose intolerant and refuse to eat any dairy products. But lactose is only present in sufficient quantities to cause problems in milk and cream. Practically all cheese, yogurt, sour cream, cottage cheese, and so on all have had the lactose removed or broken down by enzymes during fermentation and won’t cause problems. I know a lot of people fake gluten allergies too. What is the problem/mental illness happening here?
Further, a lot of "bread" has basically zero fiber, which bonds with sugars and carries them straight through the digestive system without being absorbed (which is why whole fruit is healthy but fruit juice isn't).
