Impossible Whoppers are loaded with Estrogen. Unless folks want to go to Rainbow/LB for bras, some may want to lay off. Some will do opposite.
Sorry to say this is likely just propaganda being spread by the meat industry because they're worried about loosing sales to a healthy alternative (full disclosure I eat meat, have never tried the new fake meats and have no financial stake in any of this).
I'll will point people instead to an article in Ars Technica, written by someone with an actual phd in microbiology instead. I will quote from the conclusion for those who don't want to click:
Then there are the studies that have looked into whether isoflavones can feminize men and infants and interfere with fertility and development. The general concern goes back decades and has been bolstered by the occasional case report and animal study, which have questionable applicability to human health overall.
In particular, the fear of men growing breasts from soy consumption was highlighted in a 2008 case report in which a 60-year-old man developed benign swelling of male breast tissue and elevated estrogen levels. Doctors reported that the man consumed a whopping three quarts of soymilk a day. That would provide around eight times the intake of isoflavones that have been recorded in older men in Japan and Shanghai who eat soy-heavy diets.
One nutrition researcher noted of the case report that such excessive intake of pretty much any nutritious food could result in untoward effects. For instance, if the soymilk had been fortified with calcium, it would have resulted in an overdose that can cause hypercalcemia.
Overall, analyses of numerous studies have found no evidence that isoflavone consumption in normal ranges affects male hormone levels or sperm and semen quality. Likewise, there is no conclusive evidence that soy-based infant formula has adverse effects, either. The American Academy of Pediatrics has concluded that “soy protein-based formulas are a safe and nutritionally equivalent alternative to cow milk-based formula for term infants whose nutritional needs are not met from breast milk.”
While nutrition researchers say long-term human studies could help provide more concrete conclusions, for now, there's no reason to think eating an Impossible Whopper will increase anyone's cup size.
