Strawberries come from a blossom, but have no seed inside.
I've heard that lemons are #1. The acid in lemons leaves your body on your breath.
Cantelope and watermelon are also great from what I've read.
I'm not a health expert. Two of the best books I've ever read on this stuff are "back to eden" by Jethro Kloss and The Acid - Alkaline Diet by Chistopher Vasey, N.D.
Jethro Kloss also has alot of good things to say about cayenne pepper.
One thing that Vasey says that made alot of sense to me is that, if you check the pH of your urine first thing in the morning, it will be more acid than the rest of the day. It's had all night to build up.
That's just the opposite of what the "don't eat fruit" guy says. I think he said that is the only time to check it.
