Read the passage below and answer the questions that follow :Be bone healthy1. Every time a child takes a soft drink, is he laying the groundwork for a dangerous bone disease? Fizzy and sugary drinks don’t cause osteoporosis but, because they are often a substitute for a glass of milk, the children miss out on taking in the calcium and Vitamin D they need to build a strong skeleton. Many of them also lead a sedentary lifestyle, so they aren’t getting the bone-building benefits of vigorous exercise either. These children tend to suffer from brittle bones and fractures later on in life. In addition, they could be at a risk of being diagnosed with osteoporosis at an earlier age than most others.2. The Indian society for Bone and Mineral Research (ISBMR), a body comprising experts on osteoporosis was established in 1996 with the aim of promoting research and circulating awareness about metabolic bone diseases especially this bone crippling disease. Osteoporosis starts in childhood but its consequences are apparent at a later stage in life. This condition causes bones to become riddled with holes like the framework of a house that’s been attacked by termites. This can lead to broken bones which in turn can cause deformity, chronic pain, and disability. Osteoporosis can be fatal : upto 953 of older people who suIer a broken hip, die within a year.
