In culinary terms, white meat is meat which is pale in color before and after cooking. In traditional gastronomy, white meat also includes rabbit, the flesh of milk-fed young mammals (in particular veal and lamb), and sometimes pork. [1] [2] [3] [4] In ecotrophology and nutritional studies, white meat includes poultry and fish, but excludes all mammal flesh, which is considered red meat . [5]
Various factors have resulted in debate centering on the definition of white and red meat. Dark meat is used to describe darker-colored flesh. A common example is the lighter-colored meat of poultry (white meat), coming from the breast, as contrasted with darker-colored meat from the legs (dark meat). [6] Certain types of poultry that are sometimes grouped as white meat are red when raw, such as duck and goose. Some types of fish, such as tuna, sometimes are red when raw and turn white when cooked.
The terms white, red, light and dark applied to meat have varied and inconsistent meanings in different contexts. [7] The term white meat in particular has caused confusion from oversimplification in scientific publications, misuse of the term in the popular press, and evolution of the term over decades. Some writers suggest avoiding the terms "red" and "white" altogether, instead classifying meat by objective characteristics such as myoglobin or heme iron content, lipid profile, fatty acid composition, cholesterol content, etc. [7]
In nutritional studies, white meat may also include amphibians like frogs and land snails. [8] [9] Mammal flesh (eg; beef, pork, goat, lamb, doe, rabbit) is excluded and considered to be red meat. [5] Periodically some researchers allow lean cuts of rabbit to be an outlier and categorize it into the “white meat” category because it shares certain nutritional similarities with poultry. [9] [10] [11] Otherwise, nutritional studies and social studies popularly define "red meat" as coming from any mammal, "seafood" as coming from fish and shellfish, and "white meat" coming from birds and other animals. [12] [13] Some entomologists have referred to edible insects as "the next white meat". [14]
The United States Department of Agriculture (USDA) typically classifies red meat, poultry, and seafood as their own separate categories. [15] The USDA considers all livestock animals (including beef, veal, pork) to be "red meat” because their muscles contain enough myoglobin that their fresh meat is deep red in color prior to being cooked. Poultry and seafood are not considered to be red meats because they contain less myoglobin. [16] The term white meat is used to describe poultry in particular; [17] [18] while this includes duck and geese, they are considered to be a dark meat. [19] Seafood is treated as a distinct product and not included as a type of meat by the USDA's FSIS. [20] The World Health Organization (WHO) makes a distinction between white meat and seafood. [21]
Within poultry, there are two types of meats—white and dark. The different colours are based on the different locations and uses of the muscles. White meat can be found within the breast of a chicken or turkey. Dark muscles are fit to develop endurance or long-term use, and contain more myoglobin than white muscles, allowing the muscle to use oxygen more efficiently for aerobic respiration. White meat contains large amounts of protein.
Dark meat contains 2.64 times more saturated fat than white meat, per gram of protein. [22] One commentator wrote that dark meat contains more vitamins, [23] while a New York Times columnist has stated the two meats are nearly identical in nutritional value, especially when compared with typical red meat. For ground-based birds like chicken and turkeys, dark meats occur in the legs, which are used to support the weight of the animals while they move. According to the U.S. Department of Agriculture, 28 grams (1 oz) of boneless, skinless turkey breast contains about one gram of fat, compared with roughly two grams of fat for 28 g (1 oz) of boneless, skinless thigh. [24] The numbers go up when the skin is kept in: a chicken thigh, with skin intact, has 13 grams of total fat and 3.5 grams of saturated fat per 85 g (3 oz) serving; this is about 20 percent of the recommended maximum daily intake. [25] Birds which use their chest muscles for sustained flight (such as geese and ducks) have dark meat throughout their bodies. [26]
Because of health concerns, meat producers have positioned pork as "white meat", taking advantage of the traditional gastronomic definition. The United States National Pork Board has marketed their product as "Pork. The Other White Meat".
In Israel, where Jewish dietary laws which forbid the consumption of pork are popularly practiced, "white meat" is the accepted euphemism for pork. [27]
The health effects that correlate with white meat consumption have been studied as compared to red meat and vegetarian diets. There is a decreased incidence of stroke. [28] There is no association with obesity or insulin resistance. [29] [30] White meat appears to have a neutral or favorable effect on blood coagulation profiles. [31] There is additional evidence that myoglobin promotes carcinogenesis in colorectal models and therefore epidemiologic evidence supports reduced prevalence of colon cancer in those who consume white meat as opposed to red meat. [32]
Ham is pork from a leg cut that has been preserved by wet or dry curing, with or without smoking. As a processed meat, the term "ham" includes both whole cuts of meat and ones that have been mechanically formed.
Meat is animal flesh that is eaten as food. Humans have hunted, farmed, and scavenged other animals for meat since prehistoric times. The establishment of settlements in the Neolithic Revolution allowed the domestication of animals such as chickens, sheep, rabbits, pigs, and cattle. This eventually led to their use in meat production on an industrial scale in slaughterhouses.
Poultry are domesticated birds kept by humans for the purpose of harvesting useful animal products such as meat, eggs or feathers. The practice of raising poultry is known as poultry farming. These birds are most typically members of the superorder Galloanserae (fowl), especially the order Galliformes. The term also includes waterfowls of the family Anatidae and other flying birds that are kept and killed for their meat such as the young pigeons, but does not include wild birds hunted for food known as game or quarry.
A food pyramid is a representation of the optimal number of servings to be eaten each day from each of the basic food groups. The first pyramid was published in Sweden in 1974. The 1992 pyramid introduced by the United States Department of Agriculture (USDA) was called the "Food Guide Pyramid" or "Eating Right Pyramid". It was updated in 2005 to "MyPyramid", and then it was replaced by "MyPlate" in 2011.
Mechanically separated meat (MSM), mechanically recovered/reclaimed meat (MRM), or mechanically deboned meat (MDM) is a paste-like meat product produced by forcing pureed or ground beef, pork, mutton, turkey or chicken, under high pressure through a sieve or similar device to separate the bone from the edible meat tissue. It is sometimes called white slime as an analog to meat-additive pink slime and to meat extracted by advanced meat recovery systems, both of which are different processes. The process entails pureeing or grinding the carcass left after the manual removal of meat from the bones and then forcing the slurry through a sieve under pressure. This puree includes bone, bone marrow, skin, nerves, blood vessels, and the scraps of meat remaining on the bones.
A flexitarian diet, also called a semi-vegetarian diet, is one that is centered on plant foods with limited or occasional inclusion of meat. For example, a flexitarian might eat meat only some days each week. Flexitarian is a portmanteau of the words flexible and vegetarian, signifying its followers' less strict diet pattern when compared to vegetarian pattern diets.
A plant-based diet is a diet consisting mostly or entirely of plant-based foods. Plant-based diets encompass a wide range of dietary patterns that contain low amounts of animal products and high amounts of fiber-rich plant products such as vegetables, fruits, whole grains, legumes, nuts and seeds. They do not need to be vegan or vegetarian but are defined in terms of low frequency of animal food consumption.
Pancetta is a salt-cured pork belly meat, product in a category known as salume. In Italy, it is often used to add depth to soups and pastas.
A high-protein diet is a diet in which 20% or more of the total daily calories comes from protein. Many high protein diets are high in saturated fat and restrict intake of carbohydrates.
A healthy diet is a diet that maintains or improves overall health. A healthy diet provides the body with essential nutrition: fluid, macronutrients such as protein, micronutrients such as vitamins, and adequate fibre and food energy.
In gastronomy, red meat is commonly red when raw, in contrast to white meat, which is pale in color before cooking. In culinary terms, only flesh from mammals or fowl is classified as red or white. In nutritional science, red meat is defined as any meat that has more of the protein myoglobin than white meat. White meat is defined as non-dark meat from fish or chicken.
Processed meat is considered to be any meat that has been modified in order to either improve its taste or to extend its shelf life. Methods of meat processing include salting, curing, fermentation, smoking, boiling, frying, and/or the addition of chemical preservatives. Processed meat is usually composed of pork or beef or, less frequently, poultry. It can also contain offal or meat by-products such as blood. Processed meat products include bacon, ham, sausages, salami, corned beef, jerky, hot dogs, lunch meat, canned meat, chicken nuggets, and meat-based sauces. Meat processing includes all the processes that change fresh meat with the exception of simple mechanical processes such as cutting, grinding or mixing.
A reconstituted meat, meat slurry, or emulsified meat is a liquefied meat product that contains fewer fats, pigments and less myoglobin than unprocessed dark meats. Meat slurry is more malleable than dark meats and eases the process of meat distribution as pipelines may be used.
Chicken is the most common type of poultry in the world. Owing to the relative ease and low cost of raising chickens—in comparison to mammals such as cattle or hogs—chicken meat and chicken eggs have become prevalent in numerous cuisines.
Curing is any of various food preservation and flavoring processes of foods such as meat, fish and vegetables, by the addition of salt, with the aim of drawing moisture out of the food by the process of osmosis. Because curing increases the solute concentration in the food and hence decreases its water potential, the food becomes inhospitable for the microbe growth that causes food spoilage. Curing can be traced back to antiquity, and was the primary method of preserving meat and fish until the late 19th century. Dehydration was the earliest form of food curing. Many curing processes also involve smoking, spicing, cooking, or the addition of combinations of sugar, nitrate, and nitrite.
Proteins are essential nutrients for the human body. They are one of the building blocks of body tissue and can also serve as a fuel source. As a fuel, proteins provide as much energy density as carbohydrates: 4 kcal per gram; in contrast, lipids provide 9 kcal per gram. The most important aspect and defining characteristic of protein from a nutritional standpoint is its amino acid composition.
The Western pattern diet is a modern dietary pattern that is generally characterized by high intakes of pre-packaged foods, refined grains, red meat, processed meat, high-sugar drinks, candy and sweets, fried foods, industrially produced animal products, butter and other high-fat dairy products, eggs, potatoes, corn, and low intakes of fruits, vegetables, whole grains, pasture-raised animal products, fish, nuts, and seeds.
Humans and their hominid ancestors have consumed eggs for millions of years. The most widely consumed eggs are those of fowl, especially chickens. People in Southeast Asia began harvesting chicken eggs for food by 1500 BCE. Eggs of other birds, such as ducks and ostriches, are eaten regularly but much less commonly than those of chickens. People may also eat the eggs of reptiles, amphibians, and fish. Fish eggs consumed as food are known as roe or caviar.
Pork is the culinary name for the meat of the pig. It is the most commonly consumed meat worldwide, with evidence of pig husbandry dating back to 5000 BCE.
Ground turkey, or minced turkey, is a mixture of dark and light turkey meat with remaining skin and visible fat processed together until a "ground" form emerges. The turkey meat, skin, and fat is taken off the bone and processed with additives. The final product has specific characteristics that appeal to customers, including a non pink color and non crumbly texture. The composition of ground turkey is driven by market demand, availability, and meat prices. The majority of ground turkey is made from excess thighs and drumsticks rather than the more costly breast meat. Ground turkey is a common low-fat alternative for ground beef.
