Effectiveness of a canteen-based dietary intervention for metabolic syndrome in occupational men: A randomized controlled trial.
Plain-language summary
This study tested whether a workplace canteen could improve the health of men with metabolic syndrome (a cluster of a large waist, high blood pressure, high blood sugar, high triglycerides, and low HDL or good cholesterol that together raise heart-disease and diabetes risk). It randomly assigned 321 affected men to either healthier canteen lunches plus personalized diet advice and health education, or health education alone, for six months. The men getting the better lunches saw larger drops in blood sugar, cholesterol, waist size, and weight, and were 30 percent less likely to still meet the criteria for metabolic syndrome, while the education-only group barely moved.
Key findings
- Men who received healthy lunches and personalized dietary advice saw greater reductions in blood sugar, total cholesterol, and waist size than those who only got health education.
- The intervention group also had a lower risk of metabolic syndrome after six months.
How to analyze the study yourself
- Study type
- Randomized controlled trials are strong for testing cause and effect but may not reflect real-world conditions outside the study setting.
- Population
- Men with metabolic syndrome working at an oil field in China.
- Funding
- Not reported
- Watch for
- This study found that swapping in healthier work lunches, on top of diet advice, meaningfully improved the markers behind metabolic syndrome in six months. If your workplace offers a healthier meal option, it may be worth making it your default.
