Calcium in nutrition and prevention of disease
1991
Heaney, R.P. | Barger-Lux, M.J.
The calcium intake to which human physiology is naturally adapted is on the order of 2000 to 3000 mg/day--4 to 6 times what contemporary North Americans ingest. Not everyone can adjust successfully to lower intakes. A portion of the burden of at least three major chronic diseases--osteoporosis, colon cancer and hypertension--is probably caused by low calcium intake. Given the decline in total nutrient intake over the last half century, it is unlikely that natural foods can be relied upon to bring calcium up to safe levels for the bulk of the population. Food fortification is an attractive alternative option. Processed meat products hold an important place in the U.S food intake and present a safe and inexpensive vehicle for calcium fortification.
