When oysters are eaten together with beans or tortillas, blood zinc absorption is abrogated and reduced to essentially zero.
"It's a study with oysters from, I believe, the 1950s or 1960s showing that if you give people oysters, you'll see the blood levels of zinc rise... And when you give people that oyster with beans or with a tortilla, that absorption of zinc is significantly lessened. The levels of zinc in the blood are abrogated. In fact, they go to essentially zero if beans and tortillas are given together." (said at 0:15:21)
No published record matching the specific claim that consuming oysters alongside beans or tortillas abrogates and reduces plasma zinc absorption to essentially zero was located with retrievable abstract text; this does not prove the claim false.
A supplement formulation called TRX2 containing L-carnitine, zinc, niacin, biotin, BCAAs, and selenium slowed androgenetic alopecia progression and increased the anagen-to-telogen hair ratio both systemically and topically.
"Another study looks at "The Effect of a Food Supplement and a Hair Lotion on the Progression of Androgenetic Alopecia." Note that they did not use a steak lotion. They used a supplement called TRX2, which contained L-carnitine, zinc, niacin, biotin, branched-chain amino acids, and selenium... and in both cases, it did improve the progression of androgenetic alopecia and in some cases led to hair regrowth... both resulted in reduced hair loss rate as well as an increased anagen-to-telogen hair ratio."

No published record matching a study titled "The Effect of a Food Supplement and a Hair Lotion on the Progression of Androgenetic Alopecia" or evaluating the TRX2 formulation (containing L-carnitine, zinc, niacin, biotin, branched-chain amino acids, and selenium) for androgenetic alopecia progression and anagen-to-telogen ratio was located; this does not prove the claim false.
Consumption of meat and saturated fat can improve androgen receptor density.
"Something that's not been talked about much is androgen receptor density, but one of the things we know is that meat, saturated fat, can improve androgen receptor density." (said at 0:44:46)
No published record matching the claim that consumption of meat and saturated fat improves androgen receptor density was located; this does not prove the claim false. While several studies have examined the influence of exercise, pharmaceutical agents, or total dietary composition on testosterone levels and androgen receptor expression, no peer-reviewed human or animal studies demonstrate that consuming meat or saturated fat increases androgen receptor density.
Unverified means no publication matching the claim was located; it does not prove the claim false. Spotted an error? See the corrections policy - disputes from the people quoted are prioritized.
