Medical research has established that the Beta Diet is healthier than a more conventional diet. But on average, people who have followed the Beta Diet for several decades are much more likely to be in poor health than are people whose diet is more conventional.

"Surprising" Phenomenon
Why do people who follow the Beta Diet for decades suffer from below-average health?

Objective
Any hypothesis resolving this conflict must state new information about the Beta Diet or the people who follow the Beta Diet for decades. That information must result in those who follow it for decades being less healthy than average, either because the diet has a different effect over an extended period or because those people are unhealthy in the first place.

A
On average, people who have followed the Beta Diet for their entire lives are much more likely to have a variety of healthful habits than are people whose diet is more conventional.
This deepens the mystery. If consistent followers of the diet have other healthy habits, their below-average health after an extended period is even more surprising.
B
The Beta Diet is used primarily as a treatment for a condition that adversely affects overall health.
This explains why people who follow the Beta Diet for decades are likely to suffer below-average health. They are unhealthy because of a condition the diet is intended to treat.
C
People of average health who switch from a conventional diet to the Beta Diet generally find that their health improves substantially as a result.
This makes no claim about people who follow the Beta Diet for decades. A short-term health benefit does not explain health problems that occur decades later.
D
The Beta Diet provides dramatic health benefits for some people but only minor benefits for others.
This does not imply that the Beta Diet has negative effects on the health of some people. It claims only that dieters benefit to different degrees.
E
Recent research has shown that a diet high in fruits, vegetables, and skim milk is even healthier than the Beta Diet.
This does not imply that the Beta Diet is unhealthy, or responsible for the poor health of its long-term followers. It allows the possibility that the Beta Diet is healthier than the average diet over the long-term, in which case the conflict remains unresolved.
