Vitamin D deficiency impacts Chilean population

Chile faces a significant Vitamin D deficiency crisis, with data from the National Health Survey indicating that 84% of women of childbearing age have some level of deficiency, while only 13.4% of older adults maintain acceptable levels. This issue is driven by both dietary habits and insufficient sunlight exposure.

In response, new health policies implemented since June require the fortification of certain foods, such as liquid milk, powdered milk, and wheat flour. Experts note that natural sources like egg yolks, red meats, and certain fish are essential for maintaining levels of this nutrient, which is vital for bone development, muscle function, and immune regulation.

Medical specialists warn that Vitamin D deficiency often progresses asymptomatically. Beyond bone health, the nutrient acts similarly to a prohormone, playing a critical role in metabolic regulation, immune response, and mental health. Low levels have been linked to chronic fatigue, depression, and increased susceptibility to infections. Research from Harvard suggests the body's ability to synthesize the vitamin decreases with age, making periodic blood monitoring essential for early detection of autoimmune and metabolic issues.
