I thought I was eating pretty healthily with lots of fresh fruits & kitchen-grown sprouts, but I was always too acidic with resulting fatigue. I used baking soda effectively but it can cause dizziness & damage the kidneys over time. One day I tried some hearts of romaine - I didn't know they are not bitter like regular romaine, which I don't like, until someone told me.
Amazing! If I just eat a bit of that several times a day, even the whitish part, I'm quite alkaline. Putting ground parsley on food also helps a lot.
I suspect spinach would be very alkalizing but too much of it can be a goitrogen - I. E. a danger to thyroid health.
