Ketchup
We know you love it, but don’t squeeze that blob onto your plate. “Ketchup is extremely acidic thanks to the tomatoes it’s made with,” offers Hayim. “In addition to the acid that is naturally there, ketchup is usually preserved with other chemicals that make them even more acidic and may lead to heartburn.”
Watch out for tomato sauce, too: “Pasta and marinara sauces can contribute to indigestion and heartburn,” The Nutrition Twins say. “This is especially important if you’re prone to indigestion. When you lie down to go to bed, digestion slows and the horizontal position can make heartburn and indigestion even worse.”
