Poultry meat can be divided into two categories: white and dark meat. The colour of the meat depends on the type of muscle fibre. White meat comes from muscles with mostly white fibres, while dark meat comes from muscles with more red fibres. Dark meat is considered to be the chicken legs, drumsticks, thighs, and tail.

What You'll Learn
Dark meat comes from muscles used for endurance
Poultry meat can be classified into two broad categories: white and dark meat. These different colours of meat are different types of muscle. Dark meat, usually found in the thighs and legs of birds like chickens and turkeys, has a rich colour due to its high myoglobin content. Myoglobin is a protein that helps store oxygen in muscle cells, which is essential for sustaining long-term activities such as standing or walking.
White meat, which comes from the breast and wings, has less myoglobin and is lighter in colour. The breast muscles are fast-twitch muscles, used for quick bursts of activity like flapping wings. They require energy quickly but not for an extended period, so they rely on anaerobic metabolism, which does not use oxygen and therefore produces less myoglobin.
In chickens, flying happens in bursts and requires fast-twitch muscle fibres. However, it is not exclusive to flight. For example, crocodilians, the closest relatives of birds, have mostly white meat because they are ambush predators. Mammals have their endurance and twitch muscle fibres intertwined, allowing humans to be successful long-distance runners.
Chicken drumsticks are a complex mass of small muscles, bone, and connective tissue, while thighs can be cooked bone-in or easily skinned and deboned, providing a tender cut of dark meat. Boneless chicken thighs can be used in stir-fry and pasta dishes as a richer, more flavourful alternative to white meat cuts.

White meat comes from muscles used for quick bursts of energy
Poultry meat can be classified into two broad categories: white and dark meat. These different colours indicate different types of muscles. White meat comes from muscles that are used less frequently and contain less myoglobin, a protein that gives meat its red colour. White meat is found in the breast, tenderloin, wing, and parts of the back cuts of poultry.
White meat is also known to have a milder flavour compared to its darker counterpart. This is because the breast and wing muscles are not heavily worked. The meat is leaner and dries out easily if overcooked. It is also lower in fat and calories, making it a healthier option for many. The muscles in white meat get their energy from rapidly converting carbohydrates from within the fibres themselves.
On the other hand, dark meat contains more red muscle fibres, which are used for prolonged movements such as standing or walking. These muscles get their energy from fat, which can come from within the fibres or the bloodstream. Dark meat is found in poultry legs, which are more flavourful and juicy, and can be cooked longer without drying out.
The different types of muscles in poultry result in distinct colours and characteristics for white and dark meat. White meat, coming from muscles used for quick bursts of energy, has a milder taste and is leaner, while dark meat has a more intense flavour and is juicier. These differences make each type of meat suitable for various culinary applications.

Dark meat is generally considered more flavourful
Poultry meat can be divided into two broad categories: white and dark meat. Dark meat is considered to be more flavourful than white meat, which has a milder flavour. This is because dark meat is generally juicier and harder to overcook. Dark meat is also healthier, containing larger amounts of minerals.
The difference between the two types of meat is due to the different types of muscles from which they come. White meat comes from the muscles used for flying, which require a surge of energy to get started, while dark meat comes from the muscles used for walking, which is a slower and more long-duration form of exercise. Chickens, turkeys, and other domesticated birds mostly walk around, so the dark meat is found in the legs and thighs, while the breast muscles, which are used for flying, remain less developed and stay white.
Some people may find the taste of dark meat too "gamey", and it also reminds people more of the animal it came from because it has veins, tendons, bones, and stringy bits. White meat, on the other hand, is lower in fat and calories, making it a good choice for combining with subtle flavour profiles. To keep white meat from drying out during cooking, avoid dry heat and don't be afraid to add a little fat, such as herbed butter or olive oil.
Despite these differences in taste and texture, all poultry birds can be cooked in the same basic ways, whether they are cooked whole or broken down into cuts. For example, poultry thighs can be cooked bone-in or easily skinned and deboned, and they don't dry out as easily as breasts, making them easier to cook. They can be used as a richer, more flavourful alternative to white meat cuts in stir-fry and pasta dishes.

White meat is leaner and dries out more easily
Poultry meat can be classified into two broad categories: white and dark meat. White meat comes from the breast and wings of the bird, while dark meat comes from the thighs and drumsticks. White meat is leaner and dries out more easily than dark meat. This is because white meat has less myoglobin, a protein within muscles that is full of iron and converts fat into energy. Dark meat has a higher fat content, which yields more flavor and helps it retain moisture during cooking.
White meat is also lower in fat and calories and has a milder flavor than dark meat. Because of its lower fat content, white meat releases more moisture during the cooking process, leaving it dry and less juicy. To prevent this, it is recommended to use cooking techniques and tools that help retain moisture. For example, basting white meat with sauce, pan drippings, or fat such as butter or oil during cooking can help reintroduce moisture. Using aluminum foil packets or poaching the meat are also effective ways to prevent moisture loss and create a tender texture.
When preparing white meat, it is important to avoid dry heat and not be afraid to add a little fat. Spreading a small amount of herbed butter or olive oil over the surface of the meat can help infuse flavor and moisture. Alternatively, wrapping the breast and wings in bacon can add decadence and moisture to the dish.
In contrast, dark meat is composed of endurance muscles that are used more frequently, such as walking muscles in the case of chickens. These muscles have a higher demand for energy and therefore contain more myoglobin and fat. As a result, dark meat takes longer to reach the same internal temperature as white meat during cooking.
Overall, the difference in moisture retention between white and dark meat can be attributed to their varying muscle types and fat content. White meat, coming from less-used twitch muscles, has lower fat content and releases moisture more readily during cooking, leading to drier meat. On the other hand, dark meat, derived from endurance muscles, contains more fat and myoglobin, enabling it to retain moisture and flavor more effectively.

Dark meat is healthier, containing more minerals and vitamins
White meat and dark meat are two different types of muscle. The muscles that aren't used for everyday activity get their energy differently than other muscles that are in almost constant motion. Dark meat is considered walking muscles, while white meat is considered flying muscles.
Dark meat is generally considered to be juicier and more flavourful than white meat. It is also a vitamin and mineral powerhouse, containing vitamin B6, zinc, niacin, selenium, phosphorus, iron, riboflavin, and pantothenic acid. Dark meat also contains more protein and healthy fat.
White meat, on the other hand, is lower in fat and calories and has a milder flavour. It is also higher in protein. White meat is found in the breast, breast tenderloin, and wings of a chicken.
According to the USDA, white-meat chicken has more protein per serving than dark-meat chicken. However, dark meat can still be a part of a healthy meal plan when balanced with nutrient-dense foods.
While dark meat is generally considered to be healthier due to its higher nutrient content, it is important to consider your individual health goals and needs. For example, if you have heart disease, you may need to limit your saturated fat intake, in which case white meat may be a better option.

Frequently asked questions
Dark meat chicken contains around 50% red fibres and is found in the legs, drumsticks, thighs, and tail of the chicken.
White meat has white fibres, used for short, quick movements. Red fibres, on the other hand, are used for prolonged movements such as standing. White fibres get their energy from carbohydrates, while red fibres are fuelled by fat and contain myoglobin, which is purple and full of iron.
Dark meat gets its colour from myoglobin, a protein that carries oxygen to muscles while they move. The legs and thighs help chickens get around, so these parts are darker.
White meat is lower in fat and calories, but dark meat contains higher levels of zinc, iron, vitamin C, and saturated fat. White meat has more B vitamins, while dark meat has more immunity boosters like thiamine, niacin, and B12.
