Generality
Arista is the dialect term, which has now become an official noun, referring to the main ingredient of a category of recipes typical of the Tuscan region.
It is a part of the pig's back (trinomial nomenclature: Sus scrofa domesticus) to be cooked whole, as a roasted dish in the oven or on a spit, or overcooked in a casserole; it is flavored with herbs and spices or accompanied with sauces and side dishes, depending on the specific recipe. Among the baked dishes, the most spectacular ones are in salt crust and bread crust; among the side dishes, the accompanying sauces and the most common condiments are recognized: mixed herbs, lard from colonnata, new potatoes, onions, plums and annurche apples.
What cut is it?
The dorsal part of the pig from which it is possible to obtain the loin is quite extensive; it starts from the end of the capocollo (trapezius muscle) to the hips (end of the lumbar segment, rump excluded).
In order of importance, the cuts that can be included in the loin are: loin, sirloin, tenderloin and a small part of the trapezius. With the same criterion, the bones that can be included in the loin are: ribs and vertebrae (both in small portion).
To make a "arista perfectly done, it would be advisable to use the so-called "pork loin", that is the portion of the "saddle" that affects the muscles and vertebrae to which the ribs are joined; however, it should be the responsibility of the butcher, housewife or cook to carefully separate the meat from the bone and reassemble everything (cleaning, trimming and degreasing) before cooking.
We reiterate that the most important muscle that constitutes the cut of the loin is the loin which, beyond the yoke and up to the end of the back, takes the name of "loin". Sometimes, the names "loin" and "loin" are used improperly as synonyms. Sometimes, the lumbar muscles are accompanied by small portions of capocollo, recognizable by a typically darker color but located in the same area with respect to the bone; on the contrary, the thread is on the other side of the “T”.
The pork loin features a series of extremely customizable recipes. This is because, in addition to the variables related to the animal and the cooking or seasoning methods, it is possible to carefully choose which part of the pig's back to prefer. Furthermore, it is at the discretion of the cook to choose whether to use only the loin and to separate any fillet or not. Furthermore, the husking, trimming and degreasing procedures have an equally decisive influence on the result of the recipe.

Nutritional Characteristics
As anticipated at the end of the previous paragraph, "pork loin is a dish with extremely variable nutritional characteristics. On the other hand, since the loin is the largest edible portion, it is logical to think that the nutritional translation should mainly concern this muscle." Speaking of edible portion, remember that the pork contains a part of bone and that, therefore, the edible part is around 60% (extremely variable percentage).
Assuming to use the meat of a light pig with a medium-sized lipid concentration, the relative nutritional characteristics will be summarized below.
Pork Loin Nutritional Values
The pork loin uses a fairly lean cut of meat, although this parameter depends very much on the degree of degreasing carried out during the husking and trimming. It provides more fat than some white meats, such as chicken and turkey breast, or rabbit, and is more lipidic than most fishery products, such as all crustaceans, all molluscs, cod, plaice, trout, sea bream, sea bass, swordfish, tuna fillet, dogfish and emery, grouper, bream, red snapper etc. However, the loin is certainly less caloric than: meatballs, hamburgers, sausages, coppone, ribs, bacon, rib of beef, etc.
The protein intake of the meat used for the pork loin is considerable and has a high biological value (more or less in line with the average of lean and semi-lean meats) which is why, in the diet, this food has the function of complying with the request of essential amino acids.
As it does not contain carbohydrates, the calories of pork loin come only from peptides and fats, even if the protein (55%) and lipid (45%) energy percentage can vary significantly.
The lipids of the pork are mainly composed of triglycerides, while the cholesterol fraction is significant but not excessive; in fact, contrary to egg yolk and certain milk derivatives, the meat of the pork can be contextualized in any diet. Thanks to the feed currently used for feeding light pigs, the fatty acids it contains are mainly unsaturated, with a prevalence of monounsaturated compared to both polyunsaturated and saturated ones.
From the mineral point of view, the meat for the loin contains good quantities of potassium and phosphorus; iron should also be satisfactory but, for this cut, certain nutritional tables do not report particularly high values.
As far as vitamins are concerned, excellent quantities of the water-soluble thiamine (vit. B1) and niacin (vit. PP) are observed; the concentrations of fat-soluble vit. A and vit. AND.
The pork loin is therefore a food that lends itself to most diets, but is logically excluded from vegan, raw food, lacto-ovo vegetarian, Muslim and Jewish diets.
It is easily included in the diet of overweight subjects, taking care to cook it and serve it well degreased and free of added fats.
The quantity of cholesterol is moderate and, if framed in an appropriately balanced diet, it can be part of the nutritional therapy intended for subjects with metabolic pathologies (including hypercholesterolemia).
From the hygienic point of view, the pork loin must respect the preventive rules on the risks of raw meat, as it comes from an animal potentially subject to parasitosis; its cooking is always total, NOT like that of the roast beef it plans to leave the heart of the pink-colored food.
Etymology and Historical Notes
The etymology of the term is hypothetically linked to a legend dating back to the fifteenth century. It seems that at a Florentine banquet of the "ecumenical council" (ecclesiastical meeting), Brasilio Bressarione (Byzantine cardinal) commented on a recipe based on sirloin "Aristos!", Or" the best ". From Greek to Florentine, the noun became “arista”.
On the other hand, it seems that a mention of the same name was made in a document of the thirteenth century, that is much older.
