I didn't remember writing this, sometimes there's this stupid guy who hacks my account and post with my profile.@Amazoniac , thanks for mining such interesting sources for us yet again.
I've read threads here about magnesium bicarbonate, and I've followed a recipe to make and drink it etc. But I wasn't aware that Peat had directly recommended it? I thought I'd seen him recommend magnesium carbonate?
Not that I'm recommending a diet of solely meat/fish and super starchy foods, but unless you actually meant pure starch (which isn't really food, and few people eat as a staple), I think to be fair one could distinguish different starchy foods - I'd expect at least some tubers to be more alkalinising than many grains, for instance.
I guess what I meant was that excluding veggies and fruits (fibers, allergens, goitrogens..) may be nonsense. I doubt many here exclude both. I don't know how alkalizing potatoes would be, as I discussed on the travis corner, sweet potatoes look like they have a much peat-friendly calcium/phosphorus ratio for instance. I can't eat much of them at once though. Perhaps white rice would be safe too but better consumed with (potassium + b-vitamins)-rich foods.
