"Healthy" Diet Makes You Fat?

UPDATE

Dr Eades comments in this study here


I couldn't really resist this one....it seems like a "healthy diet" - whole grains, fruits and vegetables accompanied by vegetable oil - makes people fat......

Vegetable-rich food pattern is related to obesity in China

Abstract
Objective: To investigate the association between a vegetable-rich food pattern and obesity among Chinese adults.
Design: A food pattern rich in vegetables is associated with lower risk of obesity and non-communicable chronic disease in Western countries. A similar food pattern is found in the Chinese population but the cooking method is different. A cross-sectional household survey of 2849 men and women aged 20 years and over was undertaken in 2002 in Jiangsu Province (response rate, 89.0%). Food intake was assessed by food frequency questionnaire. Factor analysis was used to identify food patterns. Nutrient intake was measured by food weighing plus consecutive individual 3-day food records. Height, weight and waist circumference were measured.
Results: The prevalence of general obesity (BMI 28 kg m-2) was 8.0% in men and 12.7% in women, central obesity was 19.5% (90 cm) and 38.2% (80 cm), respectively. A four-factor solution explained 28.5% of the total variance in food frequency intake. The vegetable-rich food pattern (whole grains, fruits and vegetables) was positively associated with vegetable oil and energy intake. Prevalence of obesity/central obesity increased across the quartiles of vegetable-rich food pattern. After adjusting for sociodemographic factors and four distinct food patterns, the vegetable-rich pattern was independently associated with obesity. Compared with the lowest quartile of vegetable-rich pattern, the highest quartile had higher risk of general obesity (men, prevalence ratio (PR): 1.82, 95% confidence interval (CI): 1.05–3.14; women, PR: 2.25, 95% CI: 1.45–3.49).
Conclusion: The vegetable-rich food pattern was associated with higher risk of obesity/central obesity in Chinese adults in both genders. This association can be linked to the high intake of energy due to generous use of oil for stir-frying the vegetables.

The operative words in that abstract: "but the cooking method is different." Your title should read "frying healthy foods in fat makes you fat."

I like how they blame it on the cooking oil in the last line. Riiiight...

What are whole grains doing in a "vegetable rich food pattern"? Sheesh.

As stated in the last sentence of the conclusion:

"This association can be linked to the high intake of energy due to generous use of oil for stir-frying the vegetables."

I didn't think that the notion that higher calorie intake is associated with obesity was breaking news.

Still enjoy your site.

A critical underpinning of a healthy diet is unquestionably the consumption of fresh vegetables and fruits. Unfortunately, many adults do not like these fine foods - so kids are the concern. Anyone interested in getting kids to develop a friendly attitude towards fruits and vegetables should take a look at a new book called “The ABC’s of Fruits and Vegetables and Beyond.” Great for kids of all ages – children even learn their alphabet through produce poems. Out only six months it is already being used in educational programs. It is coauthored by best-selling food writer David Goldbeck and Jim Henson writer Steve Charney.

hi there - thanks for the comment. Not to be too controversial, but the idea that you must have fruit and veg for a healthy diet is not "unquestioned".
