Newcastle University Study Reveals Persistent Vitamin D Deficiency in Certain Groups
Researchers at Newcastle University have discovered that certain groups, including older adults and individuals from minoritized ethnic backgrounds in northern Britain, do not experience the expected seasonal boost in vitamin D levels, even during the sunniest months. The study, published in the European Journal of Clinical Nutrition, analyzed vitamin D levels in nearly 300 participants and found that more than half of the adults aged 65 and older had insufficient vitamin D levels. The findings suggest that vitamin D insufficiency is a persistent health issue for many, challenging the belief that summer sunlight is sufficient to restore vitamin D levels.
