NPR recently did an interesting podcast on the marketing campaign that caused American consumers to abandon natural, healthy pork lard in favor of cooking with toxic, industrial garbage like Crisco. Unfortunately, although the podcast does a good job with the historical facts, the hosts still buy into the myth that saturated animal fat is unhealthy. They also make the false claim that the trans fats have been removed from products like Crisco. In reality, the processed food industry successfully lobbied the government to allow them to put "0 grams trans fat per serving" labels on products that actually do contain the stuff.
Any food that has less than 0.5 grams of trans fat "per serving" can make the "no trans fat" claim. Keep in mind that the manufacturer can determine what a serving is based on that loophole. A little "four-serving" bag of potato chips with "0 grams trans fat" could easily contain two grams of trans fat. The best approach is to avoid foods that contain any refined "vegetable" oils like corn oil, soybean oil, cottonseed oil and canola oil. When did soybeans, cottonseeds and canola become vegetables anyway? Even corn is actually a grain. By replacing these laboratory-produced oils with natural, saturated fats in my diet I've made a substantial improvement in the ratio of "good" HDL to "bad" LDL in my cholesterol profile.
