However, a recently published study by researchers at Baylor College of Medicine found no differences in the microbiome of infants at 4 to 6 weeks of age between those delivered by C-section or born vaginally. According to the researchers, one explanation is that the microbiome may actually have been established in utero from the placenta during pregnancy and even undergone some maturation prior to birth. 3,4
Infants who are breastfed after birth continue to exhibit colonization and maturation of their gut microbiome. According to a recent study from UCLA5, breast milk contributed more than 25% of the bacteria to the infant gut with an additional 10% coming from the areolar skin - findings that were most pronounced during the first month of life. More importantly, infants who continued to breast feed through 6 months of age after the introduction of solid foods had a lower incidence of obesity and asthma. Although these findings need to be corroborated, they potentially add to the body of evidence supporting the benefits of breast feeding.

So why is this important? Because interestingly enough, of the 23.5 million Americans, 75% of those diagnosed with autoimmune diseases are women over the age of 50. The reasoning behind this has in the past been attributed to hormonal, genetic and epigenetic susceptibility, or chromosomal differences. These diseases ultimately impact various organ systems such as kidneys, GI tract, skin, etc.
Give a shout out to someone you know who is combating these autoimmune diseases and how they are living a complete life for our readers!

While listening to the CBC radio program “Under the Influence” on satellite radio the other day, I was astonished to learn something I never knew about the common household product, Lysol: in the late 1920s it was marketed as a feminine hygiene product! The disinfectant was promoted as a vaginal douche to kill intimate germs and odors and safeguard “dainty feminine allure.” Its active ingredient, benzalkonium chloride, is classed as a Category III antiseptic by the FDA and is a known irritant. The formula was even more concentrated back in the ‘20s than it is today, resulting in women becoming poisoned, experiencing severe burns and some even dying.
It turns out, however, that Lysol ads were not even really about cleanliness; rather “feminine hygiene” was a euphemism for birth control. At the time, using birth control or even talking about it was taboo. According to the CBC program, this fueled sales of “under the counter” spermicides like Lysol. In fact, Lysol became the best selling method of contraception during the Great Depression.
Fortunately, times have changed and so has knowledge and discourse about contraception. Women today have many more birth control options as well as safer real feminine hygiene products – and that’s the poise that modern medical knowledge gives!
