Still not convinced? Lard is high in Vitamin D and just behind olive oil in monounsaturated fats (or MUFAs, which I have trouble saying without laughing), and tolerates high heat when cooking with it. Monounsaturated fats are the 'good fats', and including them in your diet (according to the Mayo Clinic) improves "blood cholesterol levels, which can decrease your risk of heart disease. Research also shows thats MUFAs may benefit insulin levels and blood sugar control, which can be helpful if you have Type 2 diabetes".
I got my pork fat from my Cook Pigs Ranch visit. But you may be able to find it in specialty markets, or if you have a butcher they may carry it or can order it for you. My suggestion, find a farmer. They probably have tons.
