The red-hued carotenoid lycopene is a powerful antioxidant found in many fruits and vegetables, and some food sources pack a more potent punch than others. While tomatoes are the most commonly known source, many people are surprised to learn that processed tomato products and other fruits, like gac fruit and watermelon, often contain a higher concentration of the beneficial compound.
Processed Tomato Products Are Lycopene Powerhouses
One of the most important things to understand about lycopene is that its bioavailability—how much your body can actually absorb and use—is significantly increased by heat processing. Cooking breaks down the plant’s cell walls, releasing the lycopene and making it more accessible to your body. This is why some of the most potent sources of this antioxidant are not raw, but cooked or concentrated tomato products. Cooking with a healthy fat like olive oil also dramatically enhances absorption, as lycopene is a fat-soluble nutrient.
The Top Processed Tomato Sources
- Sun-dried Tomatoes: These are arguably the richest source, with their high concentration a result of the drying process. Just a small portion can deliver a significant amount of lycopene.
- Tomato Paste: As a concentrated product, paste offers more lycopene per serving than fresh tomatoes. It’s an easy addition to soups, stews, and sauces.
- Ketchup and Sauces: While some store-bought versions contain high sugar and salt, many ketchups and marinara sauces are packed with lycopene. Checking nutrition labels for healthier versions can provide a rich source.
- Tomato Juice and Soup: Canned or heat-processed tomato juice and soup offer a substantial amount of lycopene, especially when a dash of oil is added for better absorption.
Other Lycopene-Rich Fruits Beyond Tomatoes
For those who aren't fans of tomatoes, or just want to diversify their intake, several other fruits contain high levels of lycopene. Some sources, like gac fruit, are even more concentrated than tomatoes.
Notable Fruit Sources
- Gac Fruit: This southeast Asian fruit has the highest concentration of lycopene of any known fruit or vegetable. While not widely available in all regions, it is a noteworthy source.
- Watermelon: A single medium slice of watermelon can provide a significant dose of lycopene. It is an excellent, hydrating source, and studies show its lycopene is also highly bioavailable.
- Pink Grapefruit: This citrus fruit, particularly the pink and red varieties, contains a moderate amount of lycopene. It's a refreshing way to boost your antioxidant intake.
- Papaya: Often used in tropical cuisines, papaya is another fruit with a healthy dose of lycopene. It also provides other essential vitamins and fiber.
- Apricots and Guava: Both fresh and dried apricots, as well as pink guava, are smaller but still meaningful sources of lycopene to include in a varied diet.
Vegetables That Contribute to Lycopene Intake
While fruits tend to steal the spotlight, several vegetables also contain lycopene. Incorporating these into your meals can help you get closer to your daily antioxidant goals.
Vegetables High in Lycopene
- Red Bell Peppers: These colorful vegetables contain lycopene and can be consumed raw or cooked. Roasting them can help release more of the nutrient.
- Red Cabbage: A less common but viable source, red cabbage offers a combination of lycopene and other phytonutrients.
- Carrots and Sweet Potatoes: The red varieties of carrots and sweet potatoes contain carotenoids, including lycopene, which contribute to their vibrant color and antioxidant properties.
- Asparagus: Surprisingly, asparagus contains a notable amount of lycopene despite not being red. This highlights that you can’t always judge a book by its cover—or a vegetable by its color.
Comparing Lycopene Sources: Fresh vs. Processed
To illustrate the impact of processing, the following table compares the approximate lycopene content of fresh tomatoes with various processed products and other popular fruits. Values can vary based on ripeness and other factors.
| Food Source | Approximate Lycopene Content (mg/100g) | Notes on Bioavailability |
|---|---|---|
| Fresh Tomato (Raw) | ~2.5 | Lower bioavailability than cooked/processed sources |
| Sun-Dried Tomato | ~45 | High concentration due to processing; very bioavailable |
| Tomato Paste | ~28 | Highly concentrated and very bioavailable due to heat |
| Watermelon (Raw) | ~4.5 | Good source, and bioavailable even when raw |
| Pink Grapefruit (Raw) | ~1.4 | Moderate source; naturally occurring lycopene |
| Ketchup | ~16 | Concentrated source due to processing, but check sugar content |
How to Maximize Lycopene Absorption
To get the most out of lycopene-rich foods, there are simple steps you can take to enhance your body's ability to absorb this nutrient.
- Cook Your Tomatoes: As mentioned, cooking tomatoes breaks down cell walls and releases more lycopene for your body to absorb. This is why pasta sauce is such an excellent source.
- Add a Healthy Fat: Lycopene is fat-soluble, so consuming it with a source of healthy fat, such as olive oil, avocados, or nuts, significantly increases absorption. A classic Caprese salad with olive oil is a perfect example of this.
- Diversify Your Sources: Don't rely solely on tomatoes. Including a variety of foods like watermelon and grapefruit will help ensure a consistent intake of lycopene from different sources.
- Eat the “Rainbow”: While focusing on red and pink foods for lycopene is helpful, eating a wide array of colorful fruits and vegetables ensures you get a full spectrum of antioxidants and other nutrients.
Health Benefits of a Lycopene-Rich Diet
Beyond simply answering what has a lot of lycopene, it is helpful to understand why this antioxidant is so beneficial. Lycopene's powerful free-radical fighting capabilities have been linked to several positive health outcomes in scientific studies.
- Cardiovascular Protection: Research suggests that diets rich in lycopene are associated with a reduced risk of heart disease and stroke. It may help lower LDL (bad) cholesterol and improve blood flow by protecting the lining of blood vessels.
- Cancer Prevention: Numerous studies have investigated lycopene's role in cancer prevention, particularly for prostate cancer. It is thought to protect against cellular damage that can lead to abnormal cell growth, and high intake has been linked to a reduced risk of advanced prostate cancer.

- Skin Health: Lycopene may offer some protection against sun damage by working from the inside to protect cells from UV radiation. While it's not a substitute for topical sunscreen, consuming lycopene-rich foods can contribute to overall skin health and resilience.
- Other Benefits: Emerging evidence also points to lycopene's neuroprotective effects, potential benefits for bone health, and its positive impact on the immune system.
Conclusion
While fresh tomatoes are a good starting point, those wondering what has a lot of lycopene should look to processed tomato products like sun-dried tomatoes and tomato paste for the most concentrated doses. Furthermore, watermelon, pink grapefruit, and papaya offer excellent alternative sources. By incorporating heat-processed tomato products and pairing them with healthy fats, you can maximize your body's absorption of this potent antioxidant and reap its many associated health benefits for your heart, skin, and overall well-being. A varied diet rich in all types of colorful produce remains the best strategy for optimal nutrition.
