Sure we can tell. Tryptophan is an amino acid so it is found in aliments containing a good amount of protein.

Tryptophan is a precursor for niacin, one of the vitamins of the B group, which, in turn, is a precursor for serotonin, a neurotransmitter  that influences mood, and melatonin, a hormone that regulates sleep-wake cycles.

It is said that insulin removes all amino acids form the blood with the exception of tryptophan, allowing it to get into the brain.

Animal-Based Sources

Turkey: One of the most well-known sources, turkey is often associated with tryptophan, especially in the context of inducing sleepiness after a large meal.

Chicken: Like turkey, chicken is also a good source of tryptophan.

Fish: Salmon, tuna, and other fatty fish are rich in tryptophan, along with omega-3 fatty acids, which are beneficial for brain health.

Eggs: Particularly the egg whites are high in tryptophan.

Cheese: Various types of cheese, including cheddar and Swiss, contain significant amounts of tryptophan.

Milk: Dairy products like milk are good sources of tryptophan. This is why warm milk is often recommended as a bedtime drink.

Red meat: Beef and lamb are also good sources of tryptophan.

Plant-Based Sources:

Nuts and Seeds: Pumpkin seeds, sesame seeds, sunflower seeds, and almonds are high in tryptophan.

Legumes: Soy products, such as tofu and soybeans, as well as other legumes like lentils and beans, provide a plant-based source of tryptophan.

Oats: Oatmeal and other oat-based products are not only a good source of fiber but also contain tryptophan.

Bananas: Bananas contain tryptophan as well as carbohydrates that help the body absorb it better.

Spinach: This leafy green is not only rich in vitamins and minerals but also contains tryptophan.

Whole grains: Foods like whole wheat, quinoa, and brown rice provide tryptophan along with other essential nutrients.

Chocolate: Dark chocolate, in particular, contains tryptophan, which may help explain its mood-boosting effects.

Other Sources

Pineapple: Pineapple contains tryptophan and is also a good source of bromelain, an enzyme that may help with digestion.

Tofu and soy products: As mentioned earlier, soy-based products like tofu, tempeh, and soy milk are excellent sources of tryptophan for vegetarians and vegans.

Peanuts: Peanuts and peanut butter are another good source of tryptophan.

Contrary to the popular belief, it is not turkey food with the highest content in tryptophan. Egg white and dried spirulina are the foods with the higher content, followed by dried cod and raw soy beans. Cheese, yogurt, chicken, turkey, meat, fish in general and tofu also contain tryptophan.

Combining Foods for Better Absorption

While many foods contain tryptophan, its absorption and utilization in the body can be enhanced when combined with carbohydrates. Carbohydrates cause the release of insulin, which helps clear competing amino acids from the bloodstream, allowing more tryptophan to enter the brain. This is why a snack like a banana (rich in carbs) with a glass of milk (rich in tryptophan) can be effective in boosting serotonin levels, or why a glass of milk with biscuits will help you sleep.

Including these foods in your diet can help ensure you’re getting enough tryptophan, which can contribute to better mood regulation and improved sleep.
