Calories and Nutritions in Chicken

According to the USDA, 100 grams of cooked chicken breast (meat only, roasted) contains 165 calories, while 100g cooked chicken thigh (meat only, roasted) provides 179 calories. A chicken wing (meat only, roasted) has 203 calories, and a chicken drumstick (meat only, roasted) contains 155 calories. Other cuts include chicken breast tenderloins with 89 calories, chicken back (meat only, roasted) at 239 calories, roasted dark meat chicken (meat only) with 178 calories, and roasted light meat chicken (meat only) at 153 calories.

According to the USDA, 1 kg of chicken contains approximately 890 to 2,390 calories, depending on the cut.

According to the USDA, 1 whole fried chicken (628 grams) contains 1,690 calories, while 1 whole rotisserie chicken (600 grams) contains 1,104 calories.

According to the USDA, a baked chicken breast (172 grams, bone and skin removed) contains 284 calories.

Consuming chicken is a healthy choice and its main benefits are listed below:

• Helps Brain Health: Chicken provides choline and vitamin B12, both essential for brain development and function. Many pregnant individuals do not meet daily choline needs, and low levels may be linked to neural tube defects, while higher intake may offer cognitive benefits for babies, as noted by the National Institutes of Health. A 2021 study titled "Choline Intake Correlates with Cognitive Performance among Elder Adults in the United States" by Lu Liu, et. al., suggests that increased choline intake may help prevent cognitive decline in older adults. 
• Support Skin and Joint Health: Chicken is an excellent source of collagen, which is essential for the structure of bones, skin, and tendons. As collagen production declines with age, it contributes to joint pain, muscle weakness, and wrinkles. Research from the 2021 study "A Double-Blind, Randomized, Placebo-Controlled Trial to Evaluate the Efficacy of a Hydrolyzed Chicken Collagen Type II Supplement in Alleviating Joint Discomfort" by Anaam Mohammed and Siran He suggests that chicken collagen may alleviate joint pain and stiffness. Consuming chicken cuts with skin or preparing bone broth from leftover skin and bones can provide these benefits.
• May Aid in Weight Loss: Chicken, particularly skinless chicken breast, is high in protein and low in calories. A 2015 study published in Food and Nutrition titled "Role of Poultry Meat in a Balanced Diet Aimed at Maintaining Health and Wellbeing: An Italian Consensus Document," led by Franca Marangoni and colleagues, demonstrates that chicken may reduce obesity risk when included in a vegetable-rich diet. Protein increases calorie burn during digestion, as highlighted in "A High-Protein Diet for Reducing Body Fat: Mechanisms and Possible Caveats" by Dominik H. Pesta and Varman T. Samuel in 2014 and protein helps maintain lean muscle mass, preventing metabolic slowdown during weight loss, as discussed in the research "Clinical Evidence and Mechanisms of High-Protein Diet-Induced Weight Loss" by Jaecheol Moon and Gwanpyo Koh published in Jomes Journal of Obesity and Metabolic Syndrome in 2020.
• Promoted Muscle Growth and Maintenance: Protein provides amino acids required for muscle repair and growth, and when combined with resistance training, increased protein intake enhances muscle mass and strength and aids in preserving muscle during weight loss, as noted by John W. Carbone and Stefan M. Pasiakos in “Dietary Protein and Muscle Mass: Translating Science to Application and Health Benefit,” in a 2019 study. Inadequate protein intake can result in muscle loss and functional decline in older adults.

Chicken is widely considered healthy, but consuming it also has some potential drawbacks, which are outlined below:

• Antibiotic Resistance: Consuming chicken treated with antibiotics can contribute to antibiotic resistance in humans, making infections more difficult to treat as medications may become less effective, as emphasized in the article, Antibiotic Residues in Chicken Meat: Global Prevalence, Threats, and Decontamination Strategies: A Review by Khurram Muaz, Muhammad Riaz, Saeed Akhtar, Sungkwon Park, and Amir Ismail, published in the Journal of Food Protection, through ScienceDirect. 
• Risk of heart disease: A 2020 study on “Associations of Processed Meat, Unprocessed Red Meat, Poultry, or Fish Intake With Incident Cardiovascular Disease and All-Cause Mortality” by researchers from Cornell and Northwestern University, published in JAMA Internal Medicine, found that consuming two servings per week of unprocessed red meat, processed meat, or poultry increases the risk of cardiovascular disease by 3% to 7%. The study also linked unprocessed and processed meat intake to a 3% higher risk of all-cause mortality. The study also noted that while poultry consumption showed a 4% higher risk of cardiovascular disease, the evidence is insufficient to recommend reducing poultry intake. Researchers suggested alternatives like seafood, plant-based proteins, and other nutrient-rich foods to lower the risk of heart disease. The study involved 29,682 participants, with a follow-up period of up to three decades.

Yes, consuming chicken is good for overall health because it provides essential nutrients, supports weight loss, promotes muscle growth, and contributes to bone health. Eating chicken may contribute to weight loss, as indicated by the study "The Role of Protein in Weight Loss and Maintenance" conducted by Heather J. Leidy, et. al., in 2015. Protein also supports muscle growth when combined with resistance training. Protein plays a crucial role in calcium metabolism and bone health, as concluded by Jane E. Kerstetter, Anne M. Kenny, and Karl L. Insogna in a 2011 study "Dietary Protein and Skeletal Health: A Review of Recent Human Research.”

The 2020-2025 Dietary Guidelines for Americans (DGA) recommend consuming 26 ounces of poultry, including chicken, per week, which is approximately 3.5 ounces of chicken breast per day. A 3.5-ounce serving of roasted boneless, skinless chicken breast is classified as lean poultry by the U.S. Department of Agriculture (USDA). 

The 2020-2025 Dietary Guidelines for Americans (DGA) recommend consuming no more than 26 ounces of poultry, including chicken, per week, which equates to less than 100 grams of chicken breast per day. Daily intake can vary based on individual goals and dietary preferences, but excessive consumption may increase the risk of cardiovascular disease and antibiotic resistance.

The calorie content of chicken primarily depends on the cut and preparation method rather than the specific breed. A 100-gram serving of skinless and boneless chicken breast contains approximately 165 calories, while the same amount of chicken thigh provides about 179 calories. 

According to USDA, chickens (Gallus gallus domesticus) are descendants of the Southeast Asian red junglefowl (Gallus gallus), which was first domesticated around 2000 BC in India. Scientific Reports, in the article “Origin and Evolutionary History of Domestic Chickens Inferred from a Large Population Study of Thai Red Junglefowl and Indigenous Chickens,” notes that West and Zhou proposed that chickens may have originated in Southeast Asia as early as 6000 B.C., based on archaeological and palaeoclimatic evidence. Chickens were initially used in rituals, such as using a crowing rooster to mark dawn. Different cock-fighting and pet breeds were then developed. Over the past century, selective breeding has led to the creation of commercial chicken breeds, including layers and broilers.
