“In ecologic information, correlations exist between per capita meat…consumption and prostate most cancers mortality fee [1 study cited]. In case management and potential research, the most important contributors of animal protein, meat, dairy merchandise and eggs have continuously been related to the next fee of prostate most cancers…[23 studies cited].”[1]
Here’s a quote from my ebook, The China Research[2]:
“Below unhealthy situations…IGF-1 turns into extra lively, growing the delivery and progress of latest cells whereas concurrently inhibiting the removing of outdated cells, each of which favor the event of most cancers [7 studies cited]…consuming animal-based meals will increase the blood ranges of this progress hormone, IGF-1 [3 studies cited].
With regard to prostate most cancers, individuals with greater than regular blood ranges of IGF-1 have been proven to have 5.1 instances the danger of advanced-stage prostate most cancers…when males even have low blood ranges of a protein that binds and inactivates IGF-1 [1 study cited], they’ll have 9.5 instances the danger of superior stage prostate most cancers….basic to this discovering is the truth that we make extra IGF-1 after we devour animal-based meals like meat…[3 studies cited].”
In impact, these information, summarized from a number of research and together with BOTH observational information AND mechanistic explanations is much extra dependable than citing an occasional examine. This sort of evaluation additionally turns into way more spectacular as a result of it refers to a common property of a gaggle of meals, on this case animal-based meals of which meat is a serious part. And at last, an elevated danger of 9.5 instances is big, actually fairly extraordinary.
A really related scenario exists with breast most cancers. For instance, there’s a very sturdy relationship between breast most cancers charges and the consumption of animal-based meals when evaluating numerous international locations[3]. Though this doesn’t show a cause-and-effect relationship, it nonetheless turns into way more convincing after we contemplate the mechanism by which meat and different animal primarily based meals work. For instance, animal primarily based meals improve blood (circulating) ranges of estrogen and different feminine hormones. In line with one of many main breast most cancers analysis teams on the planet, they are saying this about estrogen and breast most cancers:
“There may be overwhelming proof that estrogen ranges are a essential determinant of breast most cancers danger”[4] and moreover, “estrogen instantly participates within the most cancers course of.”[5]
