Turkey
Turkey is a poultry meat rich in protein and B vitamins, notably high in tryptophan—an amino acid involved in serotonin and melatonin synthesis. It is a lean protein source commonly consumed fresh, processed, or as deli products.

Turkey (Meleagris gallopavo) is domesticated poultry native to the Americas and now widely raised for meat globally. Fresh turkey is sold whole or portioned (breasts, thighs, drumsticks); processed forms include deli slices, ground turkey, and seasoned products. It is a staple protein source in Western cuisines, particularly in North America around Thanksgiving.
Cooked turkey breast contains approximately 30 g protein and 1.7 g fat per 100 g; dark meat (thigh, without skin) is also a high-protein option with somewhat more fat than breast meat. Turkey provides B vitamins (B6, niacin, pantothenic acid), selenium, and phosphorus. The protein is complete, supplying all nine essential amino acids. Turkey is a good dietary source of tryptophan relative to other common proteins; however, the relevance of dietary tryptophan to serotonin synthesis in the brain is complex and is not a direct cause-and-effect relationship at typical meal doses.
Tryptophan Content and Sleep
Tryptophan is a precursor to serotonin and melatonin, but its effect on sleep is not determined by turkey consumption alone; brain uptake of tryptophan depends on the ratio of competing large neutral amino acids and carbohydrate intake. Large controlled studies have not established that eating turkey meaningfully shifts sleep architecture or onset in otherwise healthy individuals.
Processing, Sodium, and Additives
Fresh, unprocessed turkey meat is low in sodium (70–80 mg per 100 g cooked). Processed turkey products—deli slices, ground turkey with added binders, or seasoned preparations—often contain added sodium (500–1000 mg per serving), nitrates or nitrites (in cured varieties), and preservatives. Individuals managing hypertension, sodium sensitivity, or those limiting processed meats should prefer fresh turkey. People with histamine intolerance should note that aged or processed turkey can accumulate histamine; fresh meat is preferable. IgE-mediated turkey allergy is uncommon but documented in clinical literature; cross-reactivity with other bird proteins (chicken, duck) is possible in sensitized individuals, though poultry is not among the nine major allergens recognized by the FDA.
Frequently Asked Questions
Does eating turkey make you sleepy?
Turkey contains tryptophan, a precursor to serotonin and melatonin, but the amount in a single meal does not directly cause drowsiness in most people. Tryptophan transport to the brain depends on the ratio of other large neutral amino acids and carbohydrate intake. The belief that turkey uniquely causes post-meal sleepiness is not well supported by controlled research; other factors such as meal size and alcohol consumption are likely more relevant.
Is turkey a healthy protein choice?
Fresh, unprocessed turkey is a lean protein source with complete amino acid content and good micronutrient density (B vitamins, selenium). Processed turkey products often contain added sodium and curing agents, making fresh turkey the preferable choice for most people.
Can people with poultry allergies eat turkey?
IgE-mediated turkey allergy is uncommon but documented. Cross-reactivity with other poultry (chicken, duck) occurs in some sensitized individuals. Anyone with a documented poultry allergy should avoid turkey unless cleared by an allergist. Note that poultry is not among the nine major food allergens recognized by the FDA.
How much protein does turkey provide per serving?
A 100 g cooked serving of turkey breast provides approximately 30 g protein; dark meat such as thigh is also protein-rich, though the exact amount varies by cut and cooking method. A typical home or restaurant serving of 150–200 g of breast delivers a substantial protein contribution depending on cut and preparation.
