Quoted from RobT:
I joined the vegan club 3 months ago for reasons similar to yours (I was having a lot of stomach/digestion problems that were not going away, despite seeing doctors and given medication that didn't work). This led me to start doing my own research as I was getting pretty frustrated with how I was feeling. Going vegan was not remotely on my radar or something that I thought I would do a very short time ago (big meat eater here)!
Well, I decided to give it a try. Definite improvement 2 weeks in. 90% improvement 4 weeks in. Feeling *much* better overall now, not only with the digestion problems I was having, but in overall health, including lower BP (like you).
I gotta apologize to my buddy rarehero as I used to give him shit for being a vegan. Sorry bro! You were right.
Based on what? Let me guess: because we have "canine" teeth?
Anyway, back on topic: Andrew Heighway sucks.
The digestive benefits are due to fiber and the best thing you can eat are leafy greens. The impact can't be overstated.
There is an easy way to validate it for yourself. Ask for a full blood test -liver function, platelet count, cholesterol, the works. Go plant based for 3 months and then ask for another blood test. Rinse and repeat. I do still eat meat, but only up to 12 oz of grass-fed organic beef. Stay away from chicken and pork and ANY processed meat. It's damn near as deadly as tobacco is.
And Andrew Heighway sucks big time.
