Physiologist: The likelihood of developing osteoporosis is greatly increased by a deficiency of calcium in the diet. █████ ████████ ███████ ███████ ████ ███████ ███ ███████ ████ ██ ██████ ███ ███████████ ███ ██ █████████ █████ █████ ████████ ███ █████ ███ ██████ ███ ██████████ ███ ███ ████ ██████ ██ ████████ ███ █████████ ██ ████████████ ██ ████ █████ ████ ██ █████████ █████ ██████ ███████ █ █████ ████ ██ ███████ ████ █████ █████████
"Surprising" Phenomenon
Why is the rate of osteoporosis much lower in countries where fruits and veggies are the main source of calcium than in countries where people get a lot of calcium from dairy products, even though dairy products usually contain more calcium per serving than do fruits and vegetables, and the chance of getting osteoporosis increases from calcium deficiency?
Objective
The correct answer should suggest a difference between the people in countries in which fruits/veggies are main source of calcium and the countries in which dairy products provide a lot of the calcium. This difference should help explain the lower rates of osteoporosis in the fruits/veggie-focused countries.

The comparison involves people in countries “where dairy products are rare.” So, we’re focused on countries where the typical fruit/veggie-eater wouldn’t be able to consume lots of dairy.

This suggests that people in the dairy countries might get less calcium than the people in the fruit/veggie countries. Although dairy has more calcium, it makes the calcium more difficult to absorb. This might explain the fruit/veggie countries’ lower osteoporosis rate.
