This guy has a great take on cholesterol that I completely agree with from what I have read, so his take on blood pressure is likely accurate, as well.
I have not looked much into high blood pressure other than the drugs my bf is on. I can't control what he does so I haven't done a lot of research. I do know that salt is not really a factor unless you have kidney issues.
Has she had her thyroid checked? Once I got mine under control a lot of things settled down for me and I lost nearly 100lbs in a year and half without changing my diet. My bp was high when I was forced on SSRIs and took a few years to go back to normal.
Thanks. Did not have the time to go through the whole article but seems really interesting. I think she had her thyroid checked about two years ago but I'll ask her.
