Transcript

Anyways, when you hear about “environmental estrogens” and male fertility they’re not talking about phytoestrogens, they’re talking about xenoestrogens, these humanmade chemicals like PCBs, pesticides that can have estrogenic effects. Where are they found the most? Fish. So it follows that “The highest…concentrations were found in urban fish eaters, followed by rural fish eaters, [then] urban vegetarians, and with the lowest levels in rural vegetarians.”
Here are the sperm counts, fisheaters versus vegetarians.

    Hi, Dr Greger. I’m vegan and love it, and am blood type A. I know people, especially blood type O, who say they NEED meat or their health declines. What do you say to that? I would like to think that no one needs meat and perhaps there’s something wrong that’s making them need meat. Could you shed any light on this for me, as I don’t know how to respond to them other than maybe it’s their blood type (like in the blood type diet). Thank you :-)
