Pork loin and other lean meats are a good choice for people on a heart-healthy diet, provided that the cooked portions are limited to 3 to 4 ounces, as recommended by Avera Heart Hospital Registered Dietician Joanne Shearer. The American Diabetes Association also recommends a 3 to 4 ounce portion of pork loin as a protein source in a diabetic diet. Because they do not contain carbohydrates, lean meats do not increase blood glucose levels.
Pork is the most widely consumed meat worldwide and pig husbandry is believed to date back to 5000 B.C. About 38 percent of the worldwide meat production is pork. The three largest consumers of pork are China, the European Union and the United States, with China accounting for about half of the worldwide consumption.
