Early Puberty and the Environment

Have you noticed girls are “blooming” earlier and earlier?  According to a new study, almost one in four black girls and one in 10 white girls in the U.S. had developed breasts by the age of seven.  SEVEN.  My daughter will be in first grade when she’s seven.  First graders should not have breasts already!

By age 8, the numbers are worse, almost 1 in 2 black girls and 1 in 5 white girls.   These numbers are getting worse.  In 1997, the proportion of white girls that had developed breasts by age seven was 5% – so in just 13 years, the number has doubled.

Early puberty is linked to early sexual experiences, low self-esteem, higher risk of eating problems,  depression, suicide, and a greater risk of breast cancer.

So what is causing this alarming trend?

There are several possible causes: the environment and childhood obesity.

One of the top environmental concerns are endocrine disruptors – chemicals that act on hormones to change bodily functions.  Bisphenol-A (BPA) sound familiar?  If not, you can read more about this chemical in plastics here, here and here.  If you drink soda – you’re ingesting a little BPA.  If you have old baby bottles (older than 2008 or so) – you’re feeding your child a little BPA.

The other endocrine disruptor commonly found in plastics are phthalates.  Phthalates are everywhere. Personal care products like perfume and nail polish,  vinyl floors, vinyl upholstery, toys, paints, packaging, detergents and even medication.   Just researching this post, I found that the medication I take to control my Crohn’s Disease is covered in a coating containing phthalates and since I’m taking large quantities per day, let’s just say my internal alarms are flying off the hook.

One other interesting finding in the study was that the prevalence of early puberty was different amongst regions.  Girls in San Francisco were found to have a lower rate (11.6%) than girls in New York (15.3%) and girls in Cincinnati (18.9%).  This could be due to San Francisco’s reputation as an area for healthy eating, exercise, low plastics and chemical use.

Let’s keep our little girls, just that. Little girls.  Not concerned about bras, sexual experiences or obsessed with their image.    Free to have tea parties with their friends, ride bikes through the neighborhood and run unabashedly through the sprinkler.

 

Free Range Eggs vs. Supermarket Eggs

In the left corner, it’s FREE RANGE EGGS.  And in the right corner, it’s generic SUPERMARKET EGGS.

A new study by Mother Earth News finds that free range eggs contain 3-6x more vitamin D than typical supermarket eggs.  Vitamin D can be absorbed from skin exposure to the sun, but many people don’t go outside enough in the winter and lack sufficient vitamin D. 

Research is finding that low levels of vitamin D may be linked to diabetes, cancer, heart disease and multiple sclerosis.

Compared to factory-farm eggs, free range eggs also contain: 1/3 less cholesterol, 1/4 less saturated fat, 2/3 more vitamin A, 2x more Omega-3 fatty acids, 3x more vitamin E, and 7x more beta carotene.  These little white eggs pack a punch.

Round 1 goes to FREE RANGE EGGS!

P.S.  In my post yesterday, I said that in order to improve indoor air quality, I would open windows in my house for at least 5 minutes every day.  Today was Day 1 and it was delightful!  The smell of fresh air and the sound of birds chirping.  Free therapy.
