Eine große Kohortenstudie in den USA ergab, dass Diäten mit einem hohen glykämischen Index mit einem höheren Lungenkrebsrisiko verbunden sind, während Diäten mit einer hohen glykämischen Last ein geringeres Risiko zeigen

Please share what foods this includes for us here in the thread 🙂
The correlation with high glycemic load was smaller but this still seems counterintuitive unless there is another risk factor that the carbs are displacing. For example, high GI foods and meat could increase cancer risk but eating more carbs decreases meat consumption so it has an overall beneficial effect.
I don’t read many of these types of studies, but is their control for „physical activity“ really controlling for exercise because it seems laughable. They broke participants into two physical activity groups: less than once a month and more than once a month.
This seems like an important distinction because high GL foods, according to the paper, are high GI foods with high carbohydrate content. Some of the biggest consumers of carbohydrates are athletes. I am a very mediocre runner and run anywhere from 1 to 5 times a week. I put on weight and lose muscle when I’m running only once a week. The exercise cutoff in the statistical analysis seems like it would include a substantial number of sedentary people in the physical activity positive group.
