Tryptophan is an essential amino acid required for the body's growth and development. It is also involved in the production of substances like niacin (vitamin B3), serotonin, and melatonin. While turkey is often associated with high levels of tryptophan, many other foods contain similar amounts, including dairy products such as cheese. Cheddar cheese, in particular, has been identified as a food with a high tryptophan content per typical serving, but it is unclear whether this amount is sufficient to induce drowsiness, as is sometimes believed to be the case with turkey.

What You'll Learn

Cheddar cheese contains tryptophan, an essential amino acid
Tryptophan is an essential amino acid that is needed for the body's general growth and development. It is also required for the body's production of important substances like niacin (vitamin B3), the neurotransmitter serotonin, and the hormone melatonin. Serotonin and melatonin are crucial in regulating sleep and mood. For instance, the consumption of turkey, which contains tryptophan, is believed to make people sleepy.
Cheddar cheese contains tryptophan, with 100 grams of cheddar containing 0.73 grams of tryptophan. In addition to tryptophan, a 100-gram serving of cheddar cheese provides 404 calories, 22.87 grams of protein, 33.31 grams of total fat, and 3.09 grams of carbohydrates. The nutritional content of cheddar cheese, including its tryptophan levels, can vary depending on factors such as storage and preparation methods.
Cheddar cheese is not the only dairy product that contains tryptophan. Other cheeses, such as cottage cheese, mozzarella, Parmesan, and Gruyere, also contain significant amounts of tryptophan. Additionally, dairy products like milk and yogurt are good sources of this essential amino acid.
It is important to note that while tryptophan is essential for the body, excessive consumption of cheddar cheese or any single food item may not be advisable due to potential imbalances in overall nutrition. A balanced diet that includes a variety of tryptophan-rich foods, such as chicken, turkey, red meat, pork, tofu, fish, beans, nuts, seeds, and eggs, can help ensure adequate tryptophan intake while maintaining a healthy nutritional profile.

Tryptophan is needed for growth and development
Tryptophan is an essential amino acid that humans and many animals cannot produce themselves. Therefore, it is necessary to obtain it through one's diet. Tryptophan is particularly plentiful in chocolate, oats, dried dates, milk, yoghurt, cottage cheese, red meat, eggs, fish, poultry, sesame, chickpeas, almonds, and sunflower seeds.
Tryptophan is a precursor to serotonin, a neurotransmitter that helps regulate appetite, sleep, mood, and pain. It is also a precursor to melatonin, a neurohormone that helps regulate the sleep-wake cycle, and vitamin B3 (niacin), which is needed for energy metabolism and DNA production.
In addition to its role in maintaining the body's proteins, muscles, enzymes, and neurotransmitters, tryptophan is necessary for normal growth and development, especially in infants. Studies have shown that corn tortillas fortified with tryptophan resulted in better weight gain in malnourished preschool children. Similarly, soybean fortification of corn tortillas with high-tryptophan soy flour improved brain development in rats. These findings suggest that tryptophan has the potential to enhance the nutritional quality and health benefits of widely consumed foods.
Furthermore, tryptophan plays a role in protein biosynthesis, which is required to sustain life. It is among the less common amino acids found in proteins but has important structural or functional roles whenever it occurs. For example, tryptophan residues help "anchor" membrane proteins within the cell membrane.

It also helps the body produce serotonin and melatonin
Tryptophan is an essential amino acid that is needed for the body's growth and development. It also plays a role in the production of important substances such as niacin (vitamin B3), the neurotransmitter serotonin, and the hormone melatonin. Serotonin and melatonin are crucial for regulating sleep and mood. While turkey is often associated with post-meal drowsiness due to its tryptophan content, many other foods contain similar amounts of tryptophan and are not believed to cause sleepiness.
Cheddar cheese is a good source of tryptophan, with 0.73 grams found in a typical serving of 1 cup (or 132 grams). This serving size also provides 533.28 kcal of energy, 30.19 grams of protein, 43.97 grams of total fat, and 4.08 grams of carbohydrates.
The body uses tryptophan to produce serotonin and melatonin through various biological processes. Tryptophan is first converted into 5-hydroxytryptophan (5-HTP) with the help of an enzyme. 5-HTP is then converted into serotonin, which is a key neurotransmitter involved in regulating mood, appetite, sleep, and other functions. Serotonin also serves as a precursor to melatonin, which is a hormone that regulates sleep-wake cycles and is produced in the pineal gland.
Consuming foods rich in tryptophan, such as cheddar cheese, can potentially improve sleep quality. This is because tryptophan increases the production of serotonin and melatonin, which are both involved in promoting sleep. Additionally, individuals who do not consume sufficient amounts of tryptophan may be more prone to experiencing sleep disturbances.

The amount of tryptophan in cheddar varies with the serving size
Tryptophan is an essential amino acid required for general growth and development. It also helps the body produce important substances like niacin (vitamin B3), the neurotransmitter serotonin, and the hormone melatonin. Serotonin and melatonin are crucial for regulating sleep and mood.
Cheddar cheese is a tryptophan-rich food, with a serving size of 1 cup diced (132 grams) containing 0.73 grams of tryptophan. This serving size also contains 533.28 kcal of energy, 30.19 grams of protein, 43.97 grams of total fat, and 4.08 grams of carbohydrates. The amount of tryptophan in cheddar cheese can vary depending on the serving size, and it is important to consider the nutritional content, RDA percentages, and levels for cheddar cheese along with its tryptophan content.
The nutritional density score of cheddar cheese is 14.00 out of 100, based on its tryptophan content and other nutrients. When considering 100 calories of cheddar cheese, the serving size is 0 grams, and the amount of tryptophan is 0 grams. However, when looking at a larger serving size of 100 grams, the amount of tryptophan in cheddar cheese is not specified.
Other high-tryptophan foods include chicken, turkey, red meat, pork, tofu, fish, beans, milk, nuts, seeds, oatmeal, and eggs. The reference dietary intake (RDI) for tryptophan is 4mg per kilogram of body weight or 1.8mg per pound. For a person weighing 70kg (approximately 154 pounds), the recommended daily tryptophan intake is around 280mg.

Other foods with high tryptophan content include turkey, chicken, and milk
Tryptophan is an essential amino acid that plays a role in the production of serotonin, melatonin, niacin, and nicotinamide. It is used to make proteins and is found in both plant and animal proteins, although animal proteins tend to have more and are easier for the human body to break down and use. Tryptophan is also available in supplement form, although some people may experience adverse effects from these.
Cheddar cheese is a food with a high tryptophan content, with 100g of the cheese containing 0.73g of tryptophan. Other foods with high tryptophan content include turkey, chicken, and milk. Turkey is often blamed for post-meal drowsiness, which is caused by the tryptophan in its meat. Chicken is another food that contains tryptophan, and it is available in both animal and plant proteins.
Milk is also a source of tryptophan, as the amino acid was first discovered after being isolated from casein, a protein found in milk. In addition to these animal products, plant foods such as nuts and soy also contain tryptophan. Fruits, vegetables, legumes, and nuts are also good sources of tryptophan and are high in fibre, which has beneficial effects on gut health.
