Deep dives

Thiamine Deficiency and Its Prevalence

Over 56% of individuals do not consume enough thiamine, or vitamin B1, which is crucial since the body cannot synthesize it and relies entirely on dietary intake. Thiamine deficiency may arise from factors such as stress, inflammation, and poor gut health, potentially creating a cycle where gastrointestinal issues worsen due to decreased vitamin absorption. The 2011 NHANES data identified this deficiency as under-recognized, with symptoms often manifesting as digestive disturbances like bloating, nausea, and food intolerances. Given its vital role in energy production and supporting both immune and nervous systems, the lack of thiamine can significantly impact one's overall health.
