Studies suggest canned tomatoes are better for you than typical supermarket (i.e., non-vine-ripened) tomatoes.
I don't think canned tomatoes get any better than Muir Glen's. I like to have some cans of whole tomatoes on hand in winter. I pour the juice they're packed in into a glass and it's the best tomato juice I can imagine.
The fire-roasted tomatoes are tasty and spicy as salsa (but don't overlook their jars of salsa, BTW). The juice these fire-roasted whole tomatoes are packed in poured into a glass surpasses V-8 for tastiness, IMO.
