Notes:

3. Not suitable for women: Women who often drink caffeinated beverages have difficulty conceiving, and women who drink cola and smoke have even more difficulty getting pregnant, so women of childbearing age should not drink it.

4. Not suitable for pregnant women: Caffeine will inhibit the normal development of the fetus in the mother's body. Drinking too much cola will often give birth to babies with low weight and higher natural mortality.
