Miscarriage Diet

See the first link. Apparently a lot of miscarriages (but not all of them) can be traced to an inadequate supply of niacin (Vitamin B3) in the diet. The Recommended Daily Allowance for niacin, for women, is about 14 milligrams per day --I assume a pregnant woman would likely need more than that.

However, logically, for a woman who happens to be pregnant but does not want to be pregnant, it could be a lot cheaper to deliberately restrict niacin intake until a miscarriage happens, than to obtain an abortion. Also, no one who is against abortion would know for sure why the miscarriage happened --such things quite naturally tend to happen to about 1/6 of all confirmed pregnancies-- and therefore the woman who chooses a Miscarriage Diet would not be stigmatized.

Immediately after the miscarriage, of course, the woman would want to restore a normal niacin intake in the diet (and there are over-the-counter vitamin pills that can quickly fill a deficiency). The third link describes what can happen if a niacin deficiency persists for too long.
