“I never imagined I would be vitamin D deficient. I live close to the beach in a relatively rural area of India and travel a lot on my bike. My skin is exposed to the sun. Yet, after 50 years of relatively healthy teeth, I found myself with a cavity. After being away from dentists for so long I had to visit one! Since I take such good care of my health and my teeth, I felt a bit defeated. But I was determined to find out why I had developed the cavity. It was a wake-up call. I got my vitamin D levels tested and found them lower than normal. And all along, I had thought I was getting a fair amount of sunshine just because of where I live!

The experience taught me a lot about this vital vitamin. I learnt that receptors are around our eyes and that if we wear sunglasses our body is tricked into believing that it’s not sunny. This can cause other parts of the body to behave inappropriately even causing sunburn. I learnt that darker skin, like mine, needs more exposure to the sun to absorb vitamin D. I also understood that calcium deficiency is usually because of vitamin D deficiency and acid yielding foods and not because of a lack of intake of calcium.

Calcium tablets should never be prescribed or taken – they only cause kidney stones and calcification of arteries. Deficient calcium intake is unknown. Dairy is not a good source of calcium either as it is acid yielding in the body. We just need to make sure that we get enough of the vital vitamin D.” – Dr Nandita Shah
