Many studies have shown that individuals who consume a diet rich in fruits and vegetables have lower rates of cardiovascular disease. However, a recent study found that a group of individuals who followed a strict vegetarian diet, which includes only plant-based foods, had higher rates of cardiovascular disease compared to a group of individuals who consumed a balanced diet that included both plant-based and animal-based foods. This finding seems contradictory to the previous studies.
Which of the following, if true, resolves the paradox?
(A) The individuals in the vegetarian group had a higher overall calorie intake compared to the individuals in the balanced diet group.
(B) The individuals in the vegetarian group had a higher average body mass index (BMI) compared to the individuals in the balanced diet group.
(C) The individuals in the vegetarian group had a higher intake of processed vegetarian foods that are high in sodium and unhealthy fats.
(D) The individuals in the balanced diet group had a higher prevalence of pre-existing medical conditions related to cardiovascular health compared to the individuals in the vegetarian group.
(E) The individuals in the vegetarian group had a higher genetic predisposition to cardiovascular disease compared to the individuals in the balanced diet group.
(A) The individuals in the vegetarian group had a higher overall calorie intake compared to the individuals in the balanced diet group.
Incorrect. A higher calorie intake doesn't directly correlate with higher rates of cardiovascular disease.
(B) The individuals in the vegetarian group had a higher average body mass index (BMI) compared to the individuals in the balanced diet group.
Incorrect. It doesn't explain why a vegetarian diet would lead to a higher BMI
(C) The individuals in the vegetarian group had a higher intake of processed vegetarian foods that are high in sodium and unhealthy fats.
Correct. This resolves the paradox. Even though they were consuming a vegetarian diet, the high sodium and unhealthy fats in processed foods could lead to higher rates of cardiovascular disease.
(D) The individuals in the balanced diet group had a higher prevalence of pre-existing medical conditions related to cardiovascular health compared to the individuals in the vegetarian group.
Incorrect. It doesn't explain why the vegetarian group would have higher rates of cardiovascular disease.
(E) The individuals in the vegetarian group had a higher genetic predisposition to cardiovascular disease compared to the individuals in the balanced diet group.
Incorrect. Although this potentially could explain the higher rates of cardiovascular disease, it doesn't explain why a vegetarian diet would lead to higher rates of cardiovascular disease.
