Campbell's soups are healthy in moderation.
But Campbell's soup does contain lots of sodium, salt and other not too good ingredients and so when eaten in excess the Campbell's could become unhealthy for you.
If you need to watch your salt or sodium intake then it would be best to avoid eating too much of Campbell's soup.
But even if you do need to watch your sodium intake you can still eat some Campbell's soup and you should be just fine.
The healthiest soup is soup made at home with your own healthy and natural ingredients.
But Campbell's soup is not bad for you as long as you watch how much Campbell's soup you eat and eat other more healthy foods.
Campbell's soup is good soup though and as long as you're overall healthy the Campbell's soup will not cause you any health issues.
