Voedingsadvies El MondoResearch Question:
Eating red and processed meats increases the chance of getting overweight?
Study Design:
This overview article contained 21 and 18 observational studies (n = 1135661).
The heterogeneity between the studies was significant.
Results and conclusions:
The researchers found (n = 113477) that a high consumption of red and processed meats the chance of getting obesity significantly with 37% [OR = 1.37, 95% CI = 1.14-1.64] increased. Significant is, there is a link at a 95% reliability.
The researchers found that the BMI with high red meat consumption 1.37 point [average difference = 1.37, 95% CI = 0.90-1.84] increased.
The researchers found that a high modified meat consumption the BMI with 1.32 point [average difference = 1.32, 95% CI = 0.64-2.00] increased.
The researchers found that a high red meat consumption the waist circumference with 2.79 point [average difference = 2.79, 95% CI = 1.86-3.70] increased.
The researchers found that a high modified meat consumption the waist circumference with 2.77 point [average difference = 2.77, 95% CI = 1.87-2.66] increased.
The researchers concluded that a high consumption of red and processed meats the chance of getting obesity, a high BMI and waist circumference probably increased. Probably because the heterogeneity between the studies was significant.

When there has been a significant heterogeneity between the studies found risk then it is not really reliable because this is an Apple-peer comparison. In the case of a significant heterogeneity between the studies, is often a subgroup analysis conducted to see if the risk actually found is reliable or not. In this review article was no subgroup analysis (because it was not possible), and as a result, the increased risk found between high consumption of red and processed meats the chance of getting obesity, a high BMI and waist circumference uncertain.
