Raw Tomatoes Vs. Tomato Sauce.

[rueyn]

I realized after a few tries that eating pasta sauce (several different brands, all gluten-free) causes massive stomach upset for me, as do canned tomatoes. However...I can eat salsa and even raw tomatoes without a single problem.

I cannot for the life of me figure out why one kind of tomato-based product would cause issues, when the base ingredient of that product (i.e. tomatoes) doesn't.

Does anyone have any ideas?

cooking alters proteins, but maybe it's an additive to those products that bother you, not the tomatoes. You could try making your own sauce.

Hey there! The person above was right, you could just be intolerant of the additives in the tomato sauce. It is very weird that we can be intolerant of spices and things like that. I just had a test done. It said I was intolerant to tomato's, basil, parsley, oregano,and lots of other things. However those are all things found in spaghetti sauce!

Count me among those who cam handle a little raw tomato, but anything cooked (ketchup, pasta sauce, pizza sauce, sundried tomatoes, etc.) really zaps me, I came to the same conclusion Jestgar did, that the cooking alters the protein structure; also cooked tomato tends to be more concentrated, i.e., you are getting MORE tomato than if eating raw.

The altering of protein structure and be tested by making the sauce yourself. I've done that and it didn't make me sick. I think it comes from processing in a mixed facility.

I agree--I now make my own sauce using Cento crushed tomatoes. Their tomato products are processed in a completely gluten-free setting--I have spoken to the company. I had on and off problems with prepared sauces, even those from companies that "list all gluten" on the labels.

Unfortunately, sometimes we have to experiment a little to figure out what is actually bothering us.

I usually make my own sauces. But you have to keep in mind, I am nightshade intolerant

I can eat raw tomatoes like candy, and often do. I am known to eat a pint of cherry tomatoes for a snack

But, I can't do a lot of sauce. I make my own, simply because it tastes better. But, tomato sauce will almost always give me heartburn. It's the sauce. It becomes very acidic when you cook it down... ever wonder why there's sugar in tomato sauce??? Try it without it; it's very bitter.

There are people who can only eat cooked fruit vs raw fruit, or the other way around.My cousin can eat cooked carrots, but raw carrots makes her throat close. As others have said, the cooking process significantly changes most foods.

FYI, the acidity of tomatoes changes as you cook them. Raw tomatoes are much less hard on the digestion than cooked tomatoes. Bad news if you have a sensitive stomach and like pasta sauce. Good news? There are lower acid tomatoes out there that you may be able to eat. They're the yellow and orange ones you see sometimes in the veggies section. Just stay away from the red ones and bottled sauce. You can make your own sauce from the low acid tomatoes, some olive oil and garlic instead.

Thank you all *so* much for the replies! It's good to know I'm not totally crazy, and that other people have experienced this, too.

So...next question...anyone have a good, simple recipe for pizza sauce?

Thanks for the gluten-free source!
