2. Introduction
Chicken is the most popular type of poultry, and it is the second most consumed meat in the world.
This “white meat” is affordable, nutritious, and it offers a wide range of nutrients for very few calories.
However, there is a common belief that chicken is a poor nutritional substitute for red meat. Is this true?

15. Protein
The nutritional value of proteins is determined first by their content of essential amino acids and their digestibility.
Animal foods in general are considered to be foods with high protein qualities.
The human body needs 20 different amino acids, nine of which are called indispensable because the body cannot make them and must get them in the diet.
2019年8月25日

16. Protein
Indispensable amino acids for adults are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Additionally, children need arginine.
2019年8月25日

Animal foods are considered to have high protein qualities, although their qualities are not always similar because of differences in essential amino acids.
The higher quality of animal protein is due to the high lysine and methionine content.
2019年8月25日

18. Protein
The amino acid content is determined the differences in the amino acid profiles between broiler breast and thigh meats.
On a percent protein basis, amounts of valine, leucine, isoleucine, and histidine were found to be significantly greater in breast meat, and glycine, hydroxyproline, hydroxylysine, threonine, and serine were greater in thigh meat.
2019年8月25日

19. Protein
The protein efficiency ratio (PER) is still used frequently as the biologically determined measure of protein quality.
The PER value found in experiments is commonly standardized for a reference protein, usually casein.
2019年8月25日

20. Fat
The DGA suggests choosing a diet containing 20 to 35% of calories from fat and less than 10% of calories from saturated fatty acids.
Dietary cholesterol be limited to an average of 300 mg/day.
Consumers should choose a diet low in fat, saturated fat, and cholesterol to help reduce the risk of getting certain diseases and to help maintain a healthy weight.
2019年8月25日

21. Fat
The lipid contents of fowl show that both poultry and game birds contain greater amounts of unsaturated [oleic acid (C18:1) is a dominant fatty acid in all tissues] than saturated fatty acids.
The dark meat and skin of fowl contain as much as or even more oleic acid (C18:1) than the total of the saturated fatty acids.
2019年8月25日

22. Fatty acids
The three acids—palmitic (C16:0), oleic (C18:1), and linoleic (C18:2 n-6)—account for at least 68% of the total fatty acids in fowl tissues.
The fatty acid composition in chicken breast from different production regimes and have found that the dominant saturated fatty acids were palmitic acid (C16:0; 21 to 24%) and stearic acid (C18:0; 15 to 17%).
2019年8月25日

23. Fatty acids Myristic acid (C14:0) contents ranged from 0.40 to 1.02%.
The dominant fatty acid was oleic acid (C18:1), then palmitoleic acid (C16:1) and gadoleic acid (C20:1). With regard to polyunsaturated fatty acids (PUFAs), linoleic acid (C18:2 n-6) was dominant, at 16.1%.
2019年8月25日

24. Fatty acids
Arachidonic acid (C20:4 n-6) was found over the range 1.5 to 5.6%.
The dominant n-3 fatty acid was found to be α-linolenic (C18:3 n-3), with a range of 1.15 to 2.51%.
The least abundant n-3 fatty acid was eicosapentaenoic acid (EPA) (C20:5 n-3), comprising 0.24 to 0.96%.
2019年8月25日

25. Fatty acids
The contents of docosahexanoic acid (DHA) (C22:6 n-3) varied from 0.67 to 3.35%.
The n-6/n-3 ratios varied from 3.37 to
the anti-inflammatory, antithrombotic,
Antiarrhythmic, and immunomodulating properties of EPA and DHA can be helpful in the prevention of atherosclerosis.
2019年8月25日

26. Fatty acids
Both n-3 and n-6 fatty acids make powerful substances in the body that play key roles in the structure and function of very cell and, ultimately, in health and well-being.
2019年8月25日

27. Cholesterol
Cholesterol is an indispensable constituent of the cell membranes and brain tissue.
There is a correlation between serum cholesterol level and mortality rate on human cardiovascular diseases.
2019年8月25日

28. Cholesterol
Endogenous cholesterol synthesis in liver is three times higher than amounts usually consumed.
Changes in plasmatic cholesterol level depend significantly on dietary cholesterol.
Knowledge of cholesterol content is important, especially in poultry, because the consumption of poultry is currently increasing based on recommendations regarding healthy nutrition.
2019年8月25日

29. Cholesterol
Chicken or turkey breast meat content is 53 mg/100 g; turkey thigh meat (61.5 mg/100 g) and chicken thigh meat is 82.9 mg/100 g.
Serving of 100 g of poultry meat contributes 18 to 28% of the dietary cholesterol limit per day.

30. Mineral salts
Minerals are the inorganic elements, other than carbon, hydrogen, oxygen, and nitrogen, that remain behind in the ash when food is incinerated.
They are usually divided into two groups: macrominerals and microminerals (or trace elements).
2019年8月25日

31. Mineral salts
Minerals are classified as either essential or nonessential, depending on whether or not they are required for human nutrition and have metabolic roles in the body.
Nonessential elements are also categorized as either toxic or nontoxic.
2019年8月25日

32. Minerals function in the body
As structural components (e.g., calcium, phosphate, and magnesium in bones and teeth).
In organic combinations as hysiologically important compounds (e.g., phosphorus in nucleotides, zinc in enzymes such as carbonic anhydrase, iodine in thyroid hormone).
In solution in body fluids to maintain pH, helping to conduct nerve impulses and control muscle contraction (e.g., sodium and potassium in blood and intracellular fluids).
2019年8月25日

33. Vitamins
Vitamins, a heterogeneous group of substances, are vital nutrients that must be obtained from the diet.
Vitamins are divided into two categories, are recognized as vitamins: the fat-soluble vitamins, of which there are four (vitamins A, D, E, and K) and the water-soluble vitamins, of which there are nine (vitamins C, B1, B2, B6, B12, niacin, pantothenic acid, and biotin).
2019年8月25日

34. Vitamins
The water-soluble vitamin group contains eight vitamins collectively known as the B-complex vitamins, plus vitamin C.
2019年8月25日

35. Riboflavin (Vitamin B2)
Riboflavin is the most widely distributed of all the vitamins and is found in all plant and animal cells, although there are relatively few rich food sources.
Riboflavin present naturally in foods in two bound forms as coenzymes: riboflavin mononucleotide and flavin adenine dinucleotide.
2019年8月25日

36. Riboflavin (Vitamin B2)
These coenzymes participate in numerous metabolic pathways, including the citric acid cycle and the β-oxidation pathway, which breaks down fatty acids.
Chicken meat is a moderately good source of riboflavin and thiamine.
Thiamine and riboflavin contents in broiler light meat are 1660 μg/kg and 1.4 mg/kg, respectively, while the same vitamins in dark meat are 1920 μg/kg and 3.0 mg/kg, respectively.
2019年8月25日

37. Pyridoxine (Vitamin B6)
Vitamin B6 activity is shown by three compounds - pyridoxol, pyridoxal, and pyridoxamine - and these are often considered together as pyridoxine.
The vitamin B6 coenzyme pyridoxal phosphate supports more than 00 different enzymes involved in reactions that include the transfer of amino groups (NH2), carboxyl groups (COO− or COOH), or water (as H and OH).
2019年8月25日

38. Riboflavin (Vitamin B2)
These enzymes support protein metabolism, blood cell synthesis, carbohydrate metabolism, and neurotransmitter synthesis.
2019年8月25日

39. Niacin
The term niacin is generic for both nicotinic acid and nicotinamide (niacinamide) in foods.
Niacin occurs naturally in poultry, meat, and liver of hoofed animals.
The niacin precursor tryptophan is found in protein-rich animal foods.
The niacin coenzymes play key roles in oxidation - reduction reactions.
