Caffeine does NOT affect calcium absorption; the things that do are: spinach, soybeans, and cocoa (contain oxalic acid which binds to calcium directly in some plant-foods making the calcium unavailable for absorption)phytates (substances found in some plant foods); dietary fiber; laxatives/diarrhea, tea (contains tannins which hinder calcium uptake), and certain meds like steroids and anti-epileptic drugs.

Annual Checkup
It is recommended that all individuals see a Family Doctor for a full medical examination annually. Adults should get their blood pressure checked (US Preventive Task Force), a flu vaccine (CDC) and more each year.
The American Dental Association recommends dental cleanings for adults at least twice annually. Some stains can only be removed by a professional cleaning.
It’s recommended by the American Academy of Ophthalmology that every adult between the ages of 18 and 80 does an eye examination at least once every two years.
It's recommended by the American Cancer Association that every adult between the age of 20 and 80 does an annual skin screening by a licensed dermatologist.
