Turkey meat is a popular choice for consumers, being the second most consumed poultry meat worldwide. It is a rich source of high-quality protein and B vitamins, which are essential for muscle growth and maintenance. However, the intense selection for rapid breast muscle development and high carcass yield has led to concerns regarding meat quality. Scientific evidence suggests that this intense selection process may contribute to a higher occurrence of growth-related myopathies and abnormalities, such as deep pectoral myopathy and pale, soft, and exudative-like meat. These abnormalities can impact the overall eating quality of the meat, with issues such as white striping and an overall toughening of the breast muscle. While providing nutritional benefits, it is important to be mindful of the potential health implications of processed turkey meat, which tends to be high in salt content.

Turkey meat is a source of high-quality protein, vitamins and minerals
Turkey meat is a rich source of high-quality protein, vitamins, and minerals. It is one of the most consumed meats globally, with its popularity stemming from its nutritional composition. Turkey is a valuable part of a balanced diet, offering a range of health benefits.
The protein in turkey is of high quality, providing all nine essential amino acids required for growth and repair. This makes it ideal for muscle growth and maintenance, as protein is a macronutrient that the body uses to build and repair muscles, bones, cartilage, skin, blood, and tissue. Turkey is also a good source of selenium, zinc, phosphorus, and iron. Selenium aids in the production of thyroid hormones, which regulate metabolism and growth. Zinc is essential for gene expression, protein synthesis, and enzyme reactions, while phosphorus helps build strong bones and teeth.
Turkey is also a source of B vitamins, including B3 (niacin), B6 (pyridoxine), and B12 (cobalamin). These vitamins are important for energy production, cell communication, amino acid formation, and the formation of red blood cells. B vitamins also support brain and nerve function, and a deficiency may manifest as high-stress levels, fatigue, or muscle weakness. The darker cuts of meat, such as the leg and thigh, are richer in certain minerals like iron, making them beneficial for women and girls of reproductive age.
In addition to its nutritional benefits, turkey is a healthier alternative to red meat. Red meat is associated with an increased risk of colon cancer and heart disease due to its high levels of saturated fat and cholesterol, which are lower in turkey. Turkey is also part of the MIND diet, which aims to slow mental decline associated with Alzheimer's disease and dementia. Consuming turkey at least twice a week as part of this diet may help preserve memory and thinking skills in older adults.

Turkey is the second most consumed poultry meat worldwide
Turkey is a popular meat that is enjoyed by people all over the world. It is a rich source of high-quality protein and B vitamins, which are essential for muscle growth and maintenance. Turkey meat is also a good source of selenium, zinc, and phosphorus. This makes it a healthier alternative to red meat, which has been linked to an increased risk of colon cancer and heart disease.
According to recent estimates, turkey meat is the second most consumed poultry meat worldwide, with an average annual consumption of 4.0 kg and 7.3 kg per capita in the European Union (EU) and the United States, respectively. The global consumption of meat is increasing, and the same is true for turkey meat. The quantity of turkey meat produced has increased two and a half times over the 30 years to 2012, from 2.2 million tonnes to 5.6 million tonnes. This increase in production is driven by the growing human population and the demand for high-quality protein.
The turkey sector is one of the major pillars of the poultry industry, which has seen significant growth in recent years. Poultry meat used to constitute a smaller portion of total meat production, but its share has significantly increased in recent years. This is partly due to the affordability of poultry meat compared to other types of meat. Cultural, religious, and economic factors also play a role in the increasing consumption of turkey meat. Certain cultures may consider specific meats taboo, while others may elevate the status of certain meats, making them central to their culinary traditions.
To meet the increasing demand for turkey meat, breeding companies have been selecting genetic lines with increased growth potential and breast muscle proportion. This has led to some meat abnormalities, such as deep pectoral myopathy and pale, soft, and exudative-like meat. However, the occurrence of these abnormalities has been sporadic, and the industry has been working to improve meat quality and safety.
In summary, turkey is a popular and nutritious meat that is consumed worldwide. It is the second most consumed poultry meat, and its production and consumption are expected to continue growing in the future.

Turkey meat abnormalities include deep pectoral myopathy, pale-soft-and-exudative meat, and focal myopathy
Turkey meat is a rich source of high-quality protein and various other nutrients. It is the second most consumed poultry meat worldwide. However, abnormalities in turkey meat have been reported, including deep pectoral myopathy (DPM), pale-soft-and-exudative (PSE) meat, and focal myopathy.
Deep pectoral myopathy (DPM) is a degenerative condition that affects the supracoracoideus muscle, also known as the pectoralis minor or deep pectoralis muscle. It is characterised by muscle degeneration, necrosis, and atrophy, resulting in an altered texture and colour. The colour can vary from a pinkish, bloody appearance to a grayish-green discoloration, giving rise to the name "green muscle disease". DPM is caused by limited blood circulation to the muscle during exercise, which triggers degenerative processes. While DPM does not pose a health risk, affected fillets must be trimmed and discarded as they are unfit for human consumption.
Pale-soft-and-exudative (PSE) meat is another abnormality observed in turkey meat. PSE meat is characterised by higher water-holding capacity, higher pH, longer sarcomere length, and higher fat concentration compared to normal meat. It also exhibits lower shear force and moisture percentage. PSE meat has a higher fat content and can retain more intracellular water, making it a viable alternative for processed meat products.
Focal myopathy is yet another abnormality that has been reported in turkeys. It is characterised by scattered and focal necrosis, granular necrosis, hypercontraction of muscle fibres, and the proliferation of connective and fat tissues. These abnormalities can have a significant impact on the overall meat quality, affecting its texture, colour, and other organoleptic qualities.
These abnormalities in turkey meat have attracted the attention of the poultry industry due to their potential economic implications. The industry is actively working to estimate the occurrence and impact of these abnormalities and to improve meat quality in modern turkey hybrids.

The colour of turkey meat depends on the job of the muscle
Turkey is a popular meat, packed with high-quality protein, B vitamins, selenium, zinc, and phosphorus. It is also a great source of muscle-building protein. But did you know that the colour of turkey meat depends on the job of the muscle?
Turkey meat comes in two colours: white and dark. The colour of the meat depends on the muscle fibres, or muscle "twitch types", that are used for different activities. Muscle physiologists refer to these types as either slow-twitch or fast-twitch muscles.
Slow-twitch, or type I, muscle fibres are used for regular, extended periods of activity. They are also called oxidative muscles, which refers to how they produce adenosine triphosphate (ATP), a cell's energy currency. The muscle cells of slow-twitch fibres rely on their mitochondria, or "factories", to produce ATP. The high number of mitochondria in these muscles is what gives them their dark colour. Turkey legs are a good example of slow-twitch muscles, as they are used continuously by the bird when it walks around.
On the other hand, white meat comes from fast-twitch, or type II, muscle fibres. These muscles are used for quick bursts of energy, like the explosive force needed for flight. However, they fatigue quickly. Unlike slow-twitch muscles, fast-twitch muscles do not heavily rely on mitochondria or oxygen to produce ATP. Instead, they use a process called glycolysis, which requires carbohydrates. White muscles have a low capacity to use oxygen during exercise and do not require a large amount of myoglobin, the iron-rich oxygen shuttle, which is why they are light in colour. The breast muscles of turkeys are an example of fast-twitch muscles, as they are used for flying, although only for very short distances.

Turkey meat is a healthier alternative to red meat
Turkey meat is a lean, low-fat source of high-quality protein and is considered a healthier alternative to red meat. It is a rich source of B vitamins, selenium, zinc, and phosphorus. Turkey meat is also a good source of vitamin B3 (niacin), which is important for efficient energy production and cell communication, and vitamin B6 (pyridoxine), which supports amino acid formation and helps produce neurotransmitters.
Red meat, on the other hand, is high in saturated fats, which have been linked to an increased risk of heart disease. Observational studies have also associated red meat consumption with a higher risk of colon cancer and other health issues. While red meat does provide some nutritional benefits, such as a higher iron content, the current recommendation across most diets is to prioritise poultry and plant-based protein sources over red meat.
Turkey meat is versatile and can be easily incorporated into various dishes, including soups, salads, and curries. It can be used as a substitute for ground beef in recipes like burgers, meatloaf, and tacos, providing a healthier option for those looking to reduce their saturated fat intake and lower their risk of heart disease.
However, it is important to note that highly processed turkey products, such as turkey ham, sausages, nuggets, and salami, should be consumed in moderation due to their high salt content. Excess salt intake has been linked to an increased risk of stomach cancer and high blood pressure.
Overall, when properly prepared and consumed in moderation, turkey meat is a healthier alternative to red meat, offering a leaner and lower-fat protein option with a similar nutritional profile to skinless chicken.
