242"It is often necessary, even desirable, for political leaders to withhold
information from the public."
99"The purpose of many advertisements is to make consumers want to buy a
product so that they will 'be like' the person in the ad. This practice is
effective because it not only sells products but also helps people feel
better about themselves."
Milk and dairy products are rich in vitamin D and calcium, substances
essential for building and maintaining bones. Many people therefore believe
that a diet rich in dairy products can help prevent osteoporosis, a disease
in which the bones weaken significantly with age and that is linked to both
environmental and genetic factors. But a long-term study of a large number
of people has found that those who have consistently consumed dairy products
throughout the years of the study have a higher rate of bone fractures than
any other participants in the study. Since bone fractures are a symptom of
osteoporosis, this study result shows that a diet rich in dairy products may
actually increase, rather than decrease, the risk of osteoporosis.
