I encourage any US Americans reading this to start looking at the salt content of your foods. It is ALWAYS high. Even canned vegetables. You specifically have to get "no salt added" canned vegetables, and it's ridiculous.
Try cooking foods yourself and adding spices and maybe a little salt. Be weary of spices even, salt is often the first ingredient. I love creole seasoning but it's all full of salt so I had to buy the individual ingredients (garlic powder, onion powder, paprika, etc.) and make it myself.
Spaghetti is a common, easy to make meal. The premade sauces are cheap but so, so full of salt. Try making your own using (no salt added) crushed tomatoes. So good!
