Observational studies are misleading and wasting of public money: Vegans and bones

"Vegans watch your bones..."

This unanimity in the media is totally baseless.
1/ this study is observational and shows only associations.
2/ The absolute risk is 4,8/1000 for meat-eaters, more exactly 47.2 (44.9, 49.7) fractures for 1000 persons during 10 years...
3/ Stating some advice or worse writing a prescription on observational studies is BS or biased governmental bla-bla.
4/ The amount of dairy in the questionnaire needs further analysis.

Classification of diet group

At recruitment, participants completed a questionnaire which asked about diet, socio-demographic characteristics, lifestyle, and medical history. A follow-up questionnaire which asked similar questions was sent to participants in 2010. Based on the responses to both questionnaires (if the participant completed the follow-up questionnaire), the participants were categorised into meat eaters, fish eaters (did not eat meat but ate fish), vegetarians (did not eat meat or fish, but ate one or both of dairy or eggs), and vegans (participants who did not eat meat, fish, dairy, and eggs) at both time points. Further details on the questionnaires, classification of diet group including agreement of diet group at baseline and follow-up, and data collection of other baseline characteristics can be found in Additional File 1: Supplementary methods [20,21,22,23,24,25,26,27]."

Same unreliable studies where you sent questionnaires at 10 y interval. The peer review is faulty.
