When severe stress is experienced, the compromised artery may narrow due to spasm, which blocks the blood flow, which leads to a heart attack.

Calcium is the principal mineral in bone, and if you don’t get enough calcium you either can’t make enough bone during growth or you tear down your bone as an adult in order to make up for what your diet doesn’t provide.
