First of all, in order to avoid different regions called different, first to clarify the premise of my text refers to the "maw", including what prairie maw, ecological maw ah and other things, it is usually seen to grow into something like this: In general, if you want to ask something to eat will turn into what, the information needed is only two areas What is this thing, is made up of what (such as ham and sausage is mainly meat and starch) people generally eat how (such as raw apples, cooked or fried fat sausage) and know that after these, we can infer their nutrient composition, and according to the way of consumption will be introduced or removed some nutrients (such as fat sausage to oil will reduce fat, the meat made into a crispy meat will increase carbohydrates and fat), and then can be based on the way to eat the fat sausages, and then the meat will increase the fat and carbohydrates and fat), and then can be analyzed according to the customary processing of the human digestive system. 100g of fresh tripe is composed of: 83.4g of water, 14.5g of protein, 1.6g of fat, 0g of carbohydrates, 104mg of cholesterol; other micronutrients do not have a particularly prominent content, and will not be repeated here. Translated into human language is: tripe is the cow's stomach, in addition to water, mainly protein, and then contains a little bit of fat. Although also derived from cattle or pigs, the yellow throat is neither a throat, nor a trachea, nor an esophagus, but rather - large blood vessels. Theoretically, in fact, these large blood vessels may also contain some cholesterol, but these cholesterol is generally more in the hardening of the blood vessels, and we eat pigs and cows, are in the young and unintelligent, not young and strong when they contribute their aortic arches to us, so there is rarely a hardening of the blood vessels, and we will see that the yellow throats are all smooth inside when you eat them.
