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.
Which one of the following is most strongly supported by the nutritionist's statements?
Most fad diets require that everyone following them eat plenty of fruits and vegetables.
This answer is unsupported. We only know that most fad diets prescribe a narrow range of nutrients, not whether they include fruits and veggies.
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 broadly protective food group.
Any two people have different health problems and thus different dietary needs.
This answer is unsupported. The stimulus indicates that many people have different health problems, but it's still possible that two people have the same health problems.
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. So we can infer that most fad diets don’t meet some people’s dietary needs.
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 foods other than fruits and veggies. We don't even know what nutrients are contained in fruits and veggies!
