Friday Favorites: Talcum Powder and Fibroids


Under is an approximation of this video’s audio content material. To see any graphs, charts, graphics, pictures, and quotes to which Dr. Greger could also be referring, watch the above video.

In the event you randomly choose a gaggle of girls and ultrasound their uterus, nearly all of them have fibroid tumors by age 50. And by most, I imply, greater than 80% of black ladies, and about almost 70% of white ladies. Half of white ladies have already got fibroids by their early 40s, and the identical may very well be mentioned for African-American ladies of their mid-30s.

After getting over the shock of how widespread fibroids are, the subsequent query turns into, why the racial disparity? Is it “food plan, stress,…environmental exposures”? Perhaps, no matter it’s may supply a clue as to what causes fibroids. For instance, African-People are inclined to have a “decrease consumption…of fruits [and] greens,” and vegatables and fruits seem protecting towards fibroids—notably citrus, right here within the Black Ladies’s Well being Research; although not, apparently, simply citrus juice.

It’s attention-grabbing; in the event you measure the degrees of beta-carotene in contemporary surgical tissue samples of uterine fibroids, and “adjoining regular [uterus tissue] obtained” throughout hysterectomies, you discover “considerably…decrease” concentrations within the fibroids. In truth, beta-carotene was not even detectable in half the fibroid specimens. The identical factor is definitely present in most cancers. Most cancerous tissues examined had undetectable ranges of beta carotene, in comparison with the traditional tissue proper subsequent to the tumor. So, perhaps “decreased ranges of [beta]-carotene” someway play a job in inflicting these circumstances? Appears like a little bit of a stretch, however you don’t know till you place it to the check. However, there had by no means been a randomized, managed, medical trial of vegatables and fruits for fibroids, till… by no means! They did do a randomized, managed trial of kind-of-a-fruit-and-vegetable-at-the-same-time—tomatoes—however for the prevention of fibroids in Japanese quail, and most of my sufferers will not be Japanese, nor quail.

The motion of lycopene, the crimson pigment in tomatoes, “in an animal mannequin might not precisely characterize lycopene motion in people.” And certainly, the Harvard Nurses’ research discovered no obvious hyperlink between lycopene consumption and fibroids. So, yeah; fruits and not less than inexperienced greens might have a “protecting impact.” However we gained’t know for certain, till they’re correctly put to the check.

Vitamin D is one other risk as to why African-People disproportionately undergo from fibroids. “Ladies with darker pores and skin are…extra prone to be Vitamin D-deficient;” as many as 80% of black ladies might have “insufficient ranges of Vitamin D,” in comparison with just one in 5 white ladies.

Vitamin D does inhibit fibroid cell proliferation—in a petri dish. It could possibly shrink tumors in your pet rat; however what about individuals? A inhabitants research did discover that “[w]omen with enough vitamin D” ranges of their blood had a few third “decrease odds of fibroids”—according to the discovering that girls who report a number of solar publicity additionally look like protected. However, till there’s an interventional trial the place ladies are randomized to vitamin D or placebo, we gained’t know for certain if vitamin D performs a job in fibroid prevention or therapy, or not.

African-American ladies are additionally extra prone to sprinkle child powder on their genitals, which can not solely double the percentages of fibroids, however might enhance the chance of ovarian most cancers—the deadliest gynecological most cancers. Inside memos present Johnson & Johnson knew in regards to the most cancers threat, however nonetheless determined to focus on African-People. “Consider us”, Johnson & Johnson mentioned, “as a lifetime good friend of the household”—a lifetime reduce quick, maybe, by its child powder, or not less than so mentioned a jury, which lately awarded a household $110 million in damages—on high of the $200 million in verdicts from final yr, with 1000’s of lawsuits pending after inner memos revealed that a long time in the past, their very own contracted toxicologists had been warning the corporate that there are a number of research displaying a most cancers hyperlink, and anybody who denies this threat “can be perceived by the general public” in the identical gentle as those that denied a hyperlink between smoking cigarettes and most cancers: “denying the plain within the face of all proof on the contrary.”
