You're getting ripped off and it's worst for you and it tastes worse. Buy crushed tomatoes (with 2 ingredients) instead. I like Colavita and Dei Fratelli, depending where I'm shopping.
1. Jarred sauce is a rip-off. Crushed tomatoes cost $1.67 or $1 for a 28 oz can. Pasta sauce costs $2 or $3. And for what? For the extra ingredients.
2. It's worse for you. My Colavita crushed tomatoes have about 6% of my daily sodium allowance per serving. A jar of pasta sauce has a lot more. Newman's Own Sockarooni has 19% of your sodium. Cabernet Marinara has 25%. Roasted Tomato & Garlic has 21%. You can always add salt and salty grated cheese, but there's no way you're going to add this much!
3. Crushed tomatoes taste better. And you can doctor them up however you want. I know some people who doctor up jarred sauce. WHY?! You can doctor crushed tomatoes and not start from expensive sodium juice! Colavita crushed tomatoes are so good you can eat them plain. You can spread them on toast. I once made pizza and my pizza sauce was undoctored crushed tomatoes and everyone asked how I made the sauce taste so fresh.
