   On average, people who have followed the Beta Diet for their entire lives are much more likely to have a variety of healthful habits

   Why this is right

   Beta dieters are in poorer health because first they get in poor health (they suffer from a condition that adversely affects overall health), then they get put by a doctor on onto the Beta Diet.

   Recent research has shown that a diet high in fruits, vegetables, and skim milk is even healthier

   Out of Scope: "healthier than Beta Diet" We know that Beta is a healthy diet. Healthier than average.
