Identifying vegans in UK Biobank.

Of 728 UK Biobank participants who self-identified as vegan at least once on a 24-hour recall (24HR) survey. Vegans were assessed on four criteria: self-identifying as vegan on the first 24HR that they participated in, not eating meat or fish on the first 24HR, not eating meat or fish on the initial assessment (IA), and no major dietary changes over the past 5 years. Only 208 UK Biobank participants met these four criteria (top row, bold). This table shows counts from all UK Biobank participants who took the 24HR (N = 210,967). After filtering by ancestry, the total of 208 was reduced to 133 European vegetarians.
