“…Internationally, all studies except India (34%) [ 46 ] reported a lower prevalence of low serum levels of B12, including Bangladesh (~<15%) [ 53 ], Liechtenstein (13.4%) [ 54 ], Panama (11.8%) [ 55 ], Spain (10.9%) [ 43 ], Costa Rica (11.2%) [ 56 ], the UK (6%) [ 42 ], Ireland (6%) [ 57 ], Canada (~<6%) [ 58 ], Ecuador (5.46%) [ 39 ], the US (~3–4% in 1999–2002 [ 41 ] and ~<7% in 2003–2006 [ 59 ]), France (3.3%) [ 60 ], Australia (2.3%) [ 61 ], and Korea (~<2%) [ 62 ]. As for our alarming prevalence of low to intermediate levels of B12 combined together (61.1%), it unexpectedly appeared to be the highest of all published studies that assessed the prevalence of low serum levels of B12 to our knowledge, including Jordan (43.5%) regionally [ 52 ]; and Costa Rica (42.4%) [ 56 ], Panama (37.5%) [ 55 ], Canada (~<28%) [ 58 ], the US (17–20%) [ 41 ], Australia (14.7%) [ 61 ], Brazil (6.4%) [ 63 ], and Finland (4.7%) [ 64 ] internationally. This raises public health concerns regarding the nutritional status of the Lebanese population.…”
