Deficiency of which nutrient has been linked to psychological and neurodevelopmental conditions according to a recent study?
Answer: Option

A major new study has found that vitamin D deficiency may play a significant role in the development of psychological and neurodevelopmental conditions. The research highlights that low vitamin D levels are not only a personal health concern but also a biological factor that can be passed down through generations, potentially affecting brain development as well as bone health. Conducted in Denmark, the study's conclusions are also consistent with clinical observations in countries like India. This reinforces the importance of maintaining adequate vitamin D levels, especially during pregnancy and early childhood, to support both mental and physical health.
