A woman at risk for osteoporosis is told by her doctor to get 1,200-1,500 milligrams of calcium every day. But when she looks at the Nutrition Facts panel on a carton of yogurt or a jug of milk, she finds that calcium is only listed by “Percent Daily Value” (%DV).

How does she convert that to milligrams?

If she’s like most of us…she can’t. And neither can her doctor.

Those were among the findings of research conducted by Laura A. Peracchio, professor of marketing at the University of Wisconsin-Milwaukee (UWM), and Lauren Block, professor of marketing at Baruch College (CUNY). The results were so compelling that the U.S. Food and Drug Administration added information to its Web site on how to translate %DV to milligrams.

Do you know how to interpret food labeling to make sure you’re getting what you need? You may think you know the answer, but it may be worth a visit to your doctor or a consultation with a nutritionist to be certain. And for free, at-your-fingertips resources, check out the FDA’s online food labeling info.

Nutrition Labels: Helpful, or Just Plain Confusing?

In response to yesterday’s post about the new FDA-approved, no-period birth control pill Lybrel, Alicia asked this question in the comment trail:

What exactly happens to your egg(s) when birth control pills prevent ovulation?

That’s a great question. First of all, let’s be clear on two important facts about the female body:

1. You’re born with all of the eggs you’ll ever need–millions of them, just chilling in your ovaries until menarche.
2. Ovulation refers to the actual release of the egg from the ovary into the fallopian tube, not the production of the egg.

Second, let’s be clear on what happens to eggs that aren’t fertilized and gestated when you’re not taking birth control.

1. At ovulation, the egg is released and travels down the fallopian tube to the uterus.
2. If it’s not fertilized, it simply disintegrates and is absorbed by the lining of the uterus.*

Logically, then, if birth control prevents ovulation from releasing the egg into the fallopian tube, it would eventually just break down and be asorbed back into the body in the uterus. But does that play out scientifically?

From Planned Parenthood of Southeastern Pennsylvania:

Your eggs are just hanging out in your ovaries until they are called upon. Not ovulating doesn’t do any damage to your body, including your eggs.

They don’t all “expire” at the same time, but your eggs have been dying since you were in your mother’s womb.

Girl fetuses have eggs, in fact we have the most eggs (5-7 million) ever when we are still inside our mom developing. A lot of those eggs die before we are even born and they continue to die throughout our life. By the time most of us reach puberty we have about 400,000 eggs left. Which is more than enough!

Some of those eggs get used, some die and some even survive menopause. Really, menopause is sort of an expiration date for the eggs that have made it that far. There may be a few still holding out, but we won’t use them after menopause.

The medical term for this process is atresia, which Stedman’s Medical Dictionary defines as “The degeneration and resorption of one or more ovarian follicles before maturation.”

So, the short answer (after that long one!) is that if the egg isn’t fertilized or if it isn’t even released, the same thing happens: it just gets absorbed back into the body. Amazing, huh?

Lively Women Q&A: What Happens to Your Eggs When You Don’t Ovulate?

Although many women are very excited about the idea of a pill that will stop their “little friend” from visiting every 28 days, the long-term effects of the drug and, more importantly, its effects, are not known. According to a WebMD report,

Side effects of Lybrel are similar to other low-dose oral contraceptives, including an increased risk of blood clots, particularly in smokers and women over 35, and breakthrough bleeding.

Perhaps more importantly however, cancer experts, like NYU’s Julia Smith, MD, are concerned about the lack of long-term data measuring the impact of continuous-use hormones on the risk of breast and other hormone-fueled cancers.

“This is something that has not been carefully studied yet. We don’t have any evidence that there is a problem, but we certainly have many instances in the history of medicine where problems only showed up at a much later date after long-term exposure and widespread use,” says Smith, director of the Lynne Cohen Breast Cancer Preventive Program at the NYU Cancer Institute.

Moreover, she tells WebMD, “When you tamper with the way the body works naturally you can’t predict long-term outcome until you study long-term outcome. And right now we don’t have that data.” (source)

Lybrel’s FDA approval comes on the heels of Seasonale, which offers women the opportunity to reduce periods to only four each year, approved in 2003.

It’s up to you and your doctor to determine whether an oral contraceptive or another form of birth control is right for you, and which specific product in your ideal category is best suited to your medical and lifestyle needs.

But that aside, what do you think of this? Are you excited about the chance to just do away with your period, or would you rather it stick around? Is every month too often, or just right? Is four times a year not enough, or still too many? Share your opinion in the comments!
