13) The following report appeared in an archaeology journal.

"The discovery of distinctively shaped ceramic pots at various prehistoric sites scattered

over a wide area has led archaeologists to ask how the pots were spread. Some believe

the pot makers migrated to the various sites and carried the pots along with them; others

believe the pots were spread by trade and their makers remained in one place. Now,

analysis of the bones of prehistoric human skeletons can settle the debate: high levels of

a certain metallic element contained in various foods are strongly associated with people

who migrated to a new place after childhood. Many of the bones found near the pots at a

few sites showed high levels of the metallic element. Therefore, it must be that the pots

were spread by migration, not trade."

14) 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.
