According to a survey, despite a diet that includes high levels of refined sugars, processed foods, and sodas, which are known to lead to obesity and diabetes, only 15% of Japanese adults are obese, while the obesity rate for American and Australian adults who also consume high levels of sugars and processed foods is 35% and 27% respectively.
All of the following, if true, most help to resolve the contradiction above EXCEPT:The paradox is that Japanese adults have a much lower obesity rate even though their diet also includes foods linked to obesity.
A good resolver should explain why the Japanese obesity rate is lower
despite the unhealthy parts of the diet.
(A) The average Japanese meal contains significantly fewer calories compared to the average American or Australian meal.
This helps. If Japanese meals have fewer calories overall, then Japanese adults may consume less total energy even if their diet includes refined sugars and processed foods.
(B) The Japanese lifestyle includes a higher level of physical activity, such as walking and cycling, compared to that of Americans or Australians.
This helps. More physical activity can offset calorie intake and help explain the lower obesity rate.
(C) The Japanese diet, although containing high levels of sugars, also includes large amounts of fish and vegetables, which provide essential nutrients and balance the overall diet.
This helps at least somewhat. It suggests that the overall diet may be healthier and more balanced than the unhealthy-food description alone implies.
(D) Unlike Americans or Australians, the Japanese have a cultural practice of smaller portion sizes and not eating to the point of fullness.
This helps. Smaller portions directly reduce total calorie intake, which can explain the lower obesity rate.
(E) The Japanese genetic predisposition makes them less likely to store excess calories as fat compared to Americans or Australians.
This is the exception. The contradiction is mainly about diet and lifestyle, and this answer introduces a broad genetic claim without tying it to the survey’s dietary comparison. It is much less grounded than the other choices, which directly explain how Japanese adults may consume fewer net calories or have a healthier overall lifestyle.
Answer: (E)
