In order for our bodies to operate properly, a variety of acids are needed. Many of these acids can be found in our food supply. Knowing which foods contain acids is important to help us maintain a healthy metabolism. In addition to being found in natural foods, acids can be found in a variety of commercially prepared foods.
Dark Leafy Greens
Foods found in the dark, leafy greens family contain ascorbic acid. Included in this category are kale, leeks, mustard greens, dandelion greens, collards and spinach. Mustard spinach, in particular, contains rich amounts of ascorbic acid (vitamin C). According to www.nutritiondata.com, a 1-cup serving of raw spinach will provides 195mg of the acid (325 percent of your daily nutritional allotment of ascorbic acid).
Spices and Herbs
There are a variety of spices and herbs you can choose from that will provide you with ascorbic acid. Chives contain the richest amount, with more than 100mg of the vitamin in a 1-cup serving. Other spices and herbs that contain rich amounts of ascorbic acid include thyme, parsley, coriander and willow cites the USDA.
Turkey
Animal-based sources can contain a wealth of amino acids, the building blocks of protein. One essential amino acid is known as tryptophan. Tryptophan is found in the eggs, neck, organ meats (kidneys, gizzards and heart) of the turkey. A 3-oz. serving of turkey breast will supply you with 32g of this nutrient plus 64 percent of your daily recommended allotment of protein and amino acids.

A variety of fin fish contain protein and a mixture of amino acids. A 3-oz. serving of salmon can contain 62g of amino acids. Salmon varieties that contain equivalent amounts of amino acids include chum, king, Chinook, farm-raised, wild, red (also known as sockeye) and pink. Other fin fish that contain amino acids include herring, cod, tuna varieties, sardines, trout and mahi mahi.

If you desire a snack, a 1-oz. serving of unseasoned pork rinds will supply you with 34 percent of your daily nutritional recommendations for protein and amino acids. You can receive 17g of protein and amino acids by eating this portion size. Be aware that pork rinds are high in saturated fats and sodium, however.
