The food thing may (or may not) have been true in the hunter/gatherer culture... but in modern times? Amongst the population that the statistic comes from? The hormonal change seems more likely... but I'm at a loss as to what hormonal changes would be so specific in subsequent pregnancies as to indicate the number of (presumably successful) previous pregnancies. If it's it a biological effect it seems more likely to me that its environmentally linked to the presence of multiple male siblings, not the number of pregnancies. I do agree, intuitively, with your unspoken assumption at the end: it seems most likely that a very small gene change could cause homosexuality. Since very little of the libido, the sex drive or behavior isn't usually altered: just the gender of attraction. It also must be a fairly "easy" change since the result is so common. I'm not sure if I believe the "1 in 10" claim but homosexuality is far from rare in the population. Lastly it must be a "simple" change since the vast majority of homosexuals are completely "normal" otherwise: homosexuality isn't associated with known genetic anomalies, birth defects or other issues. In other words if it took a lot of "work" and change to make somebody homosexual it may then be more likely to also effect other genetic changes. In short I really wouldn't surprised if, at the genetic level, there's a very fine (and pretty damn malleable) line between "straight" and "gay".
