That is alot of sodium, even with moderate sweating and proper intake of water I wouldn't habitually eat two cans a day.
Besides, much of the nutrients in foods get lost in the canning process.
I would go with a healthier substitute.
It isn't that much sugar, but it certaintly could be done away with. Whether or not it is too much depends on your goals and what the rest of your nutrient intake is like.
Personally, I would ditch it.
