Building your bone bank account – start early!

A large handful of dates and a big glass of ice cold milk. Yum! This simple snack was my daily childhood after school energy replenishment. Without realising it I was making great deposits in my bone bank account when my body most needed it – the teenage years. About 45% of our total skeleton is laid down in adolescence. How strong our bones get during this mega-growth period determines our bone strength for the rest of our lives.
It’s sort of like an n shape. We build up calcium in our bones until our early 20’s, it tapers off for the next 20 or so years and then we hit the calcium down-hill slide. As adults we can slow down this calcium loss but what counts most is how much calcium we had in our bones to start with. This is why it’s so important for teenagers to eat plenty of calcium. Compared with children or young adults, teenagers actually absorb more calcium from their food. It’s a great design feature that helps them meet their huge calcium needs – around 4-5 serves of dairy foods each day.
