All proteins are not created equal. The ones that are best for you are highpurine proteins, which are commonly found in fattier meats. This is not to say that you should cut out chicken or fish, but you need the heavier proteins most because they help slow down your rate of oxidation. Choose from this list of proteins when deciding on a meal or snack.
High Purine: organ meats (pate, liver, etc.), herring, mussels, sardines, anchovies
Moderate Purine: beef, bacon, dark meat chicken, duck, lamb, spareribs, dark meat turkey, veal, wild game, salmon, shellfish (lobster, shrimp, crab), oysters, scallops, octopus, squid, dark tuna
