Nutritionist: Most fad diets prescribe a single narrow range of nutrients for everyone. But because different foods contain nutrients that are helpful for treating or preventing different health problems, dietary needs vary widely from person to person. However, everyone should eat plenty of fruits and vegetables, which protect against a wide range of health problems.
Summary
Most fad diets prescribe a narrow range of nutrients for everyone. But dietary needs vary widely from person to person because different foods have different nutrients for treating and preventing different health problems. However, everyone should eat plenty of fruits and vegetables because these foods protect against a range of health problems.
Strongly Supported Conclusions
Most fad diets do not meet the dietary needs of at least some people.
A
Most fad diets require that everyone following them eat plenty of fruits and vegetables.
This answer is unsupported. We don’t know what specifically most fad diets require. We only know that most fad diets prescribe a narrow range of nutrients.
B
Fruits and vegetables are the only foods that contain enough different nutrients to protect against a wide range of health problems.
This answer is unsupported. Saying these are the “only” foods with these characteristics is too strong. We only know that fruits and vegetables are an example of a food group containing a diversity of nutrients.
C
Any two people have different health problems and thus different dietary needs.
This answer is unsupported. It is possible that you could have two people with the same health problems.
D
Most fad diets fail to satisfy the dietary needs of some people.
This answer is strongly supported. We know that the dietary needs of people vary widely and that most fad diets prescribe a narrow range of nutrients. It’s inevitable that most fad diets don’t meet some people’s dietary needs.
E
There are very few if any nutrients that are contained in every food other than fruits and vegetables.
This answer is unsupported. We don’t know what nutrients are contained in other foods.
