About these women who were interviewed...
1- How many of them were working mom's under the stress of having two full-time jobs at once? Some women can wing it, no problem. But let's face it, working mom's carry a LOT of excess stress as they are pulled in two directions. Stress, for certain, is a risk factor for miscarriage.
2- How many women were regular users of the Pill prior to trying to get pregnant? Even if a woman stops taking the Pill, it can take a long time, in many cases, for the woman's body to get back to a normal, healthy state. The Pill not only messes with a woman's ovulation cycle, but it also thins the lining of the uterus. Even if fertilization occurs, if her uterus is still thin, the baby can't implant, thus a miscarriage occurs.
3- How many of them drank a mix of both coffee and pop? Perhaps coffee isn't the main culprit.
4- Were these women's progesterone levels checked prior to entry into this study? If her levels are low, that too can cause miscarriages.
5- Were these women checked for previous miscarriages? If she has a history of miscarriages, then there might be a physiological pattern completely unrelated to her beverage choice.
6- Were other health concerns taken into consideration? Did all the women in the study have a clean bill of health? Even things like undetected hypo/hyperthyroid can cause miscarriages.
7- Are these women taking prescription medications that may effect their female health?
8- Did any of these women lead destructive lifestyles prior to attempting to get pregnant: excessive use of alcohol and/or drugs, multiple sex partners, etc.
9- Did any of these women have STD's?
Perhaps they're right... but I'm definitely a skeptic. I just find it hard to believe that caffeine is that big of a reason for miscarriages. Perhaps in huge quantities- but anything is huge quantities is dangerous.
