Add the salt pork, onion and cayenne; bring to a boil. Reduce to simmer, and cook uncovered for 1-1/2 to 2 hours, or until thickened and creamy. Do not allow to boil. Stir in the bacon fat or butter, taste and season as needed with salt, pepper and Cajun seasoning.
Pay extra attention to your iron intake if you follow a vegan diet, since you rely solely on non-heme iron. Be aware that your body does not absorb non-heme iron as well as it does heme. Focus on plant-based foods with the highest iron content so that you can increase your ferritin levels. Broccoli, asparagus and dark leafy greens such as spinach, collards and kale are the richest iron sources among vegetables, while lima beans and kidney beans are iron-rich legumes.
Ferritin Rich Foods. A close-up of sliced steak on a piece of slate. Overview. The body requires iron to function properly; specifically, it supports the blood in your body and forms the central part of hemoglobin. The foods in your diet supply all the iron that you need--at least that is the theory. When the digestive system processes your food, the iron is absorbed in the intestines and is stored in the cells of your body as ferritin until it is required.
