Interesting question. It brought up 3 things for me. The difference between fresh (organically grown) tomatoes and processed tomato juice in a can can be two completely different animals. Personally, anything that comes in a box, can, bottle or a bag should be avoided or minimized.
So we know Mr. Dreamboat husband drinks tomato juice every morning . . . but . . . what does the rest of his diet look like? Maybe the culprit lays somewhere else.
A new subject of interest for me is the Lymph System. Since there is nothing like the heart to pump that fluid around like the blood, it depends on Movement and/or Exercise to circulate it around the body. Lymph is highly responsible for carrying out Toxic Wastes. If he is bed ridden he needs a lot of massage work done.
Also, tomatoes are an Acid food but the concern should be about the chemical process that happens once a food substance gets in the body. Ex: Apple Cider Vinegar is very Acidic but when it gets in the body it raises the pH up toward Alkaline.
Here's what I tell all my guys: If you've got too much Uric Acid, you're too Acidic. You need to look for ways to move the pH of your body chemistry up toward Alkaline.
