20 Foods That Help Heartburn
Almonds

Generally alkaline (low in acid), almonds are high fiber content, monounsaturated fatty acids and omega-3 fatty acids. This means that they will keep you full between meals, lowering the risk of overeating and therefore the chances of getting heartburn.
Pro Tip: When it comes to almonds, portion control is key. Try to keep your snacks to one serving size which is approximately 23 almonds.
