What fruit is highest in tryptophan?

4 min read

According to nutritional data, tropical fruits like Mamey sapote and dried figs offer some of the highest concentrations of tryptophan among fruits. This essential amino acid plays a crucial role in the body, acting as a precursor for mood-regulating serotonin and sleep-inducing melatonin.

Quick Summary

The fruit highest in tryptophan is Mamey sapote, with concentrated amounts also found in dried figs and other exotic fruits. This article details the specific fruits rich in this amino acid, explains its health benefits, and offers guidance on incorporating these foods into your diet.

Key Points

  • Mamey Sapote: This tropical fruit generally has the highest tryptophan concentration among all fresh fruits.

  • Dried Fruit Power: The drying process concentrates nutrients, making dried figs and dates exceptionally high in tryptophan per gram.

  • Tryptophan-to-Serotonin Pathway: The body converts tryptophan into the mood-regulating neurotransmitter serotonin and sleep-inducing melatonin.

  • Combine for Better Absorption: Pairing tryptophan-rich fruits with carbohydrates, like in a smoothie or with oatmeal, can aid absorption.

  • Fruits are Not Sole Sources: While valuable, fruits offer less tryptophan than high-protein foods like meat and dairy, and should be part of a balanced diet.

Mamey Sapote Leads the List of Fresh Fruits

For those seeking the highest tryptophan content in a fresh fruit, the Mamey sapote often tops the charts. A 2022 study by FitAudit compiled a list of fruits and berries with their tryptophan content per 100g, showing Mamey sapote as a leading source among its fresh counterparts. Native to Central America and the Caribbean, this sweet fruit is not only delicious but also a potent source of this important amino acid. While not as common as bananas or kiwi, its superior tryptophan concentration makes it a noteworthy addition to a health-conscious diet.

The Role of Exotic Fruits

Other tropical and lesser-known fruits also provide significant amounts of tryptophan. These include:

  • Jackfruit: This large, spiky fruit is another strong contender, packing a considerable amount of tryptophan per serving.
  • Cherimoya: Sometimes called the 'custard apple,' cherimoya also contains noteworthy levels of the amino acid.
  • Avocado: While often thought of as a vegetable, this single-seed berry provides moderate amounts of tryptophan alongside healthy fats.

Dried Fruits Offer Concentrated Tryptophan

When fruit is dried, its water content is removed, which concentrates all the remaining nutrients, including tryptophan. This process makes certain dried fruits an even more potent source per gram than their fresh counterparts. Dried figs and dates are excellent examples of this effect. A 40-gram serving of dried figs contains a measurable amount of tryptophan, which can add up significantly over time. Dates are also a rich source of this amino acid, providing a sweet way to boost your intake. The concentration of nutrients makes dried fruits a convenient, high-impact option for increasing tryptophan consumption.

A Comparative Table of Tryptophan-Rich Fruits

To illustrate the varying levels of tryptophan, the following table compares the approximate content per 100g of various fruits, based on available nutritional data. Note that content can vary by cultivar and ripeness.

Fruit (per 100g) Form Tryptophan Content Source
Mamey Sapote Fresh ~50 mg
Dried Figs Dried ~20 mg
Jackfruit Fresh ~30 mg
Cherimoya Fresh ~30 mg
Kiwi Fresh ~20 mg
Banana Fresh ~10 mg
Pineapple Fresh ~9 mg

How Tryptophan in Fruit Supports Your Health

Beyond being a building block for proteins, tryptophan serves a critical purpose in synthesizing important neurotransmitters and hormones. The body converts tryptophan into 5-HTP, which is then used to create serotonin, a crucial regulator of mood, appetite, and sleep. Serotonin is often referred to as the body's 'feel-good' chemical. Furthermore, serotonin can be converted into melatonin, the hormone that signals to your body when it's time to sleep. Consuming tryptophan-rich fruits, therefore, supports this entire process, potentially aiding in better sleep and improved mood stability.

Maximizing Tryptophan Intake from Fruits

To get the most out of tryptophan-rich fruits, consider combining them with other nutrients that help facilitate the conversion process. Pairing fruits with a carbohydrate source can help the body prioritize tryptophan absorption over other amino acids. Here are some simple ways to incorporate them into your diet:

  • Blend Mamey sapote or banana into a smoothie with milk or yogurt.
  • Add chopped dried figs or dates to a bowl of oatmeal or whole-grain cereal.
  • Top a slice of whole-wheat toast with a mashed avocado.
  • Enjoy a snack of kiwi and almonds for a synergistic effect. Foods containing Vitamin B6, such as bananas, also help the conversion process.

Additional Fruits with Notable Tryptophan

While Mamey sapote and dried figs are the highest, many other fruits contribute to your overall tryptophan intake. A balanced diet featuring a variety of these foods is beneficial. Other options include:

  • Plums: Fresh or dried, these offer moderate amounts.
  • Tomatoes: Technically a fruit, tomatoes contain a decent concentration.
  • Dates: Excellent when dried, they are a rich and sweet source.
  • Grapefruit: A moderate source of tryptophan.
  • Cantaloupe: Provides a moderate boost.

The Full Picture: Tryptophan from All Food Sources

It's important to remember that while certain fruits are the highest among their category, overall tryptophan intake is most effectively achieved through a balanced diet including other sources. High-protein foods, such as turkey, chicken, fish, cheese, eggs, and nuts, generally provide far more tryptophan per serving than any fruit. Therefore, fruits should be considered part of a varied diet that includes these other key sources. Focus on incorporating these fruits as a mood-boosting and sleep-supporting component of your daily nutrition, rather than relying solely on them for your total tryptophan needs.

Conclusion

When asking 'what fruit is highest in tryptophan,' the answer points to Mamey sapote for fresh options and dried figs for concentrated sources. While other fruits like jackfruit, cherimoya, and kiwi also contribute, it is the more exotic and dried varieties that stand out. Incorporating these fruits into a balanced diet rich in other protein sources can effectively support your body's production of mood-regulating serotonin and sleep-inducing melatonin. The key is to enjoy a diverse range of foods to ensure you meet your overall nutritional needs.

Frequently Asked Questions

Among fresh fruits, Mamey sapote is consistently identified as having the highest concentration of tryptophan. Dried figs and dates are also excellent sources due to their concentrated nutrient content.

Bananas do contain tryptophan, but they are a moderate source compared to other fruits like Mamey sapote or dried figs. A medium banana has about 11mg of tryptophan.

Yes, pineapple contains tryptophan. One cup contains about 10mg of tryptophan, and it also contains bromelain, an enzyme that can aid digestion and reduce inflammation.
