Chicken meat is made up of two types of muscle fibres: white fibres, which are used for short, quick movements, and red fibres, which are used for prolonged movements such as standing. White meat chicken, found in the breasts and wings, contains about 10% red fibres, while dark meat chicken, found in the legs and thighs, contains around 50% red fibres. The red fibres in dark meat chicken contain more capillaries for increased blood flow and oxygen, which gives the meat its reddish colour. The reddish colour comes from a protein called myoglobin, which is purple and full of iron. Dark meat chicken is also higher in fat and calories, but it is still a lean protein source.

What You'll Learn
White meat dries out quicker
White meat chicken dries out quicker than dark meat chicken. White meat is found in the breasts and wings, while dark meat is found in the legs, thighs and drumsticks.
White meat chicken is leaner and dries out easily if overcooked. It is best cooked using quick methods such as broiling, sauteing, stir-frying and grilling. White meat should be cooked until it is completely white, not pink.
Dark meat chicken, on the other hand, has a higher fat content, which makes it juicier and more flavorful. It is better suited to longer, slower and lower heat cooking methods such as roasting, braising and frying.
The difference in moisture content and cooking methods is due to the different types of muscle fibres present in white and dark meat. White meat contains mostly white muscle fibres, which are used for short, quick movements and rapidly convert carbohydrates into energy. In contrast, dark meat contains more red muscle fibres, which are used for prolonged movements such as standing and are fuelled by fat.
The colour of the muscle fibres is due to the presence of myoglobin, a purple, iron-rich protein that helps convert fat into energy. Dark meat contains more myoglobin, which gives it its reddish colour.

Dark meat is juicier and harder to overcook
Chicken meat is made up of two basic types of muscle fibres: white fibres, which are used for short, quick movements, and red fibres, which are used for prolonged movements such as standing. White muscle fibres rapidly convert carbohydrates from within the fibres themselves into energy, whereas red muscle fibres are fuelled by fat, giving them their darker colour.
Red muscle fibres contain more capillaries for increased blood flow and oxygen to the area, which is why they are darker in colour. Because they contain fat and proteins, red fibres are more flavorful than white. Most muscles contain a combination of both types of fibres, but we refer to muscles with mostly white fibres as white meat, and muscles with more red fibres as dark meat.
Dark meat chicken contains around 50% red fibres and is found in chicken legs and thighs, which are more flavorful and juicy, and can be cooked longer. The legs and thighs are the parts of the chicken that the bird uses most, so they have more myoglobin, which is what transports oxygen throughout muscles. This is why dark meat is redder in pigment. When cooked, the reddish colour turns brown.
White meat, found in the breasts and wings, contains about 10% red fibres. This part of the chicken is leaner and milder in flavour, and dries out easily if overcooked. Broiling, sauteing, stir-frying, grilling, and other quick methods are best for white meat, which tends to dry out.

Dark meat has more myoglobin
The colour of chicken meat is determined by the presence of myoglobin, an oxygen-carrying protein or hemoprotein. Myoglobin is responsible for transporting oxygen throughout muscles, similar to how hemoglobin functions in the rest of the body. The muscles that require more oxygen will have a higher concentration of myoglobin, resulting in darker meat.
Chickens, being flightless birds, primarily use their legs and thighs for movement, leading to a higher occurrence of myoglobin in these areas. As a result, the leg and thigh muscles exhibit a darker colour compared to the breast or wings, which remain less developed and appear white. The dark meat in chicken legs contains around 50% red fibres, while white meat in the breast and wings contains about 10% red fibres.
Myoglobin is purple in colour and rich in iron content. It is responsible for the reddish hue observed in dark meat. When cooked, this reddish colour transforms into a brown shade. The presence of myoglobin also contributes to the juicier texture and richer flavour of dark meat.
Dark meat, due to its higher myoglobin content, is a good source of iron and other nutrients. It provides more micronutrients such as zinc, riboflavin (vitamin B2), and vitamin C. In contrast, white meat offers higher levels of B vitamins, including vitamin B12, niacin (vitamin B3), and vitamin B6.
The difference in myoglobin levels between white and dark chicken meat is a result of the distinct types of muscle fibres present. White muscle fibres are used for short, quick movements and efficiently convert carbohydrates into energy. On the other hand, red muscle fibres are utilised for prolonged movements, such as standing, and derive their energy from fat and the bloodstream. The red fibres obtain their colour from myoglobin, which plays a crucial role in converting fat into energy.

White meat is leaner
Chicken is composed of two types of muscle fibres: white fibres, which are used for short, quick movements, and red fibres, which are used for prolonged movements such as standing. White muscle fibres rapidly convert carbohydrates from within the fibres into energy, while red muscle fibres are fuelled by fat and contain more capillaries for increased blood flow and oxygen to the area.
White meat chicken is made up of muscles that contain mostly white fibres, while dark meat chicken contains more red fibres. White meat, found in the breasts and wings, contains about 10% red fibres and is lean and mild in flavour. It dries out easily if overcooked and is best cooked using quick methods such as broiling, sauteing, stir-frying, and grilling.
Dark meat chicken, on the other hand, contains around 50% red fibres and is found in chicken legs, thighs, and drumsticks. It is more flavourful and juicy and can be cooked longer.
The difference in colour between white and dark meat is due to the presence of myoglobin, an oxygen-carrying protein or hemoprotein that gives meat its reddish colour. The more myoglobin is present in the meat, the darker it appears. Chickens use their legs and thighs to get around, so these parts contain higher amounts of myoglobin, making them darker than the breast or wings.
White meat is considered leaner than dark meat because it has lower fat and calorie content. It is recommended for those following a low-fat, heart-healthy diet or looking to cut calories and fat. White meat also has a higher protein content, providing 10 grams more protein per serving than dark meat. However, dark meat contains higher levels of certain nutrients such as iron, zinc, and vitamin C, while white meat is richer in B vitamins, phosphorus, vitamin B12, niacin (vitamin B3), and vitamin B6.

Dark meat is more nutrient-rich
White meat and dark meat chicken have several differences, including their nutritional content. Dark meat chicken is generally considered to be more nutrient-rich than white meat. This is because it contains more myoglobin, an oxygen-carrying protein that gives the meat its reddish colour. The muscles that a bird uses the most require more oxygen, so they have more myoglobin. As chickens are flightless birds, they use their legs and thighs to get around, making the meat in these areas darker than the breast or wings.
Dark meat chicken contains more total fat, saturated fat, and sodium, which gives it a juicier, fattier flavour and mouthfeel. It also provides more micronutrients such as iron, zinc, and riboflavin (vitamin B2). On the other hand, white meat chicken has more phosphorus, vitamin B12, niacin (vitamin B3), and vitamin B6.
Dark meat chicken is also a good source of healthy fats, containing mostly unsaturated fat and some saturated fat. It has a higher content of zinc, an essential mineral that supports immune function and aids in wound healing. Additionally, dark meat chicken contains higher levels of iron, an essential mineral that plays a vital role in transporting oxygen throughout the body.
While white meat chicken is known to be leaner and lower in fat, dark meat chicken is still a fairly lean protein source. It is important to note that both white and dark meat chicken provide numerous nutritional benefits, and the right choice depends on individual health goals, preferences, and health conditions.
