Apples can neutralize stomach acid.
According to some experts, Granny Smith and Braeburn apples are great acid neutralizers and those who prefer natural remedies might want to give them a try. Apples contain malic and tartaric acids which naturally neutralize stomach acids. This reduces stomach pressure, which lessens the likelihood of heartburn. History notes that people have used the natural antacids of apples for many years to relieve discomforts brought about by heartburn. Since apples are natural you can eat as many apples as you’d like without getting any adverse effects.
Apple cider vinegar is another good remedy.
Vinegar is also another popular homemade remedy for heartburn, especially the apple cider vinegar. You can take a couple of teaspoonfuls of this vinegar in a cup of water or in applesauce to experience an immediate healing effect. Vinegar adds to the bulk of the acid in the digestive system and aids in the digestion process.
