Since dairy products are an abundant source of calcium, dairy avoidance presents an issue where one would need to conscientiously consume from other sources.  Eating replacement foods high in calcium is important.  Oranges, broccoli, almonds, and many other foods contain calcium, but supplementation is often a good idea as well. An 8 ounce glass of skim milk contains about 300 milligrams of calcium as compared to 1 fresh orange which contains about 52 milligrams of calcium. The minimum recommended daily intake of calcium for an otherwise healthy person is 1,000 milligrams. That’s about four 8 ounce glasses of milk compared to 20 oranges!
