I found it interesting to discuss vitamin D deficiency because it is something that has been recently relevant to me, since moving to England. (1) Vitamin D is important for healthy bodily function, as it influences calcium levels, maintains organ functions, and it needed for healthy bones. Low levels of vitamin D could lead to increased risks of osteoporosis and hip fractures in adults or rickets in children. (2) Although it is still debated on what adequate vitamin D levels should be, it is certainly evident that insufficient levels of this vitamin it is a global issue. (3) The leading risk factors for low vitamin D levels include older age, female sex, lower latitudes, winter season, darker skin, and dietary habits. Living in England, having little sunlight and darker skin, I can feel how my mood and body change when I do not supplement vitamin D into my diet.
