Tomatoes and tomato products are by far the richest sources of lycopene, but watermelon, pink guava, papaya, and pink grapefruit also deliver meaningful amounts. Lycopene is a pigment that gives red and pink fruits their color, and it happens to be one of the most potent antioxidants found in food, with roughly twice the free-radical-fighting capacity of beta-carotene and up to 100 times that of vitamin E.
The Highest-Lycopene Foods
Lycopene content varies widely depending on the food and how it’s prepared. Here are the top sources, measured in milligrams per 100 grams:
- Tomato paste: 5.4–150 mg
- Ketchup: 9.9–13.4 mg
- Tomato sauce: 6.2 mg
- Watermelon: 2.3–7.2 mg
- Pink guava: 5.2–5.5 mg
- Fresh tomatoes: 0.72–4.2 mg
- Papaya: 0.11–5.3 mg
- Pink grapefruit: 0.35–3.36 mg
- Carrots: 0.65–0.78 mg
- Rosehip: 0.68–0.71 mg
The enormous range for tomato paste (5.4 to 150 mg) reflects how concentrated the product is. A tablespoon of thick, double-concentrated paste packs far more lycopene than a tablespoon of a thinner variety. Across the board, processed tomato products dominate the list because concentrating tomatoes removes water and packs more pigment into every bite.
Why Processed Tomatoes Beat Fresh Ones
A fresh tomato straight from the vine contains less accessible lycopene than the same tomato after it’s been cooked, crushed, or concentrated. Heating tomatoes increases lycopene extractability by about 37%, because heat breaks down cell walls and releases the pigment from the plant tissue where it’s tightly bound. That’s why tomato paste, sauce, and even ketchup consistently rank higher than raw tomatoes.
This doesn’t mean fresh tomatoes aren’t worth eating. They still provide lycopene along with vitamins C and K, potassium, and fiber. But if your goal is to maximize lycopene specifically, a spoonful of tomato paste stirred into a soup or stew delivers more than a whole raw tomato.
Eating Fat With Lycopene Matters
Lycopene is fat-soluble, which means your intestines absorb it much more efficiently when fat is present in the same meal. Research on absorption suggests you need at least 10 grams of fat (about two teaspoons of oil) alongside cooked tomato products for good uptake. For raw tomato dishes like salads, that threshold rises to around 15 grams, or just over one tablespoon of olive oil.
This is one reason the classic combination of tomatoes cooked in olive oil works so well nutritionally. A pasta sauce simmered with a drizzle of oil, or a slice of pizza with its oily cheese, both create conditions where your body can pull more lycopene from the food. Eating watermelon or pink grapefruit alongside some nuts or cheese follows the same principle.
Beyond Tomatoes: Other Good Sources
If you’re not a tomato fan, or you just want variety, several other fruits carry useful amounts of lycopene. Watermelon is the standout, delivering up to 7.2 mg per 100 grams, which puts it in the same range as many cooked tomato products. A generous wedge of watermelon on a summer afternoon can provide a solid dose without any cooking required.
Pink guava is another strong source at around 5.2 to 5.5 mg per 100 grams. It’s less commonly available in many grocery stores, but frozen guava pulp works well in smoothies. Papaya ranges widely (0.11 to 5.3 mg) depending on the variety and ripeness, with deeper pink-fleshed papayas landing at the higher end. Pink grapefruit rounds out the list at up to 3.36 mg per 100 grams. The common thread is color: the redder or pinker the flesh, the more lycopene it typically contains.
Carrots and rosehips appear on lycopene lists, but their concentrations are low enough (under 1 mg per 100 grams) that you’d need to eat large quantities to get a meaningful amount. They’re better thought of as minor contributors rather than primary sources.
How Much Lycopene You Actually Need
There’s no official recommended daily intake for lycopene, but clinical trials give a useful range. Studies on oxidative stress protection have used doses of 6.5, 15, and 30 mg per day. At the lower end, around 7 mg daily has shown up to 50% protection of DNA in white blood cells from oxidative damage. At the higher end, 30 mg per day has been studied in prostate cancer patients consuming tomato-sauce-based meals over three weeks, with measurable reductions in markers of cellular damage.
Hitting 7 to 15 mg a day is straightforward if you regularly eat tomato-based meals. A half-cup of tomato sauce or a couple tablespoons of tomato paste gets you there. Even a few cups of watermelon can contribute meaningfully. Getting to 30 mg takes more deliberate effort, like eating tomato-rich dishes daily, but it’s entirely achievable through food alone.
Practical Ways to Get More Lycopene
Building lycopene into your diet doesn’t require supplements or dramatic changes. A few simple habits make a noticeable difference. Cook your tomatoes when you can, whether that means a quick pan sauce, roasted cherry tomatoes, or soup. Add a fat source to the meal: olive oil, cheese, avocado, or nuts all work. Choose tomato paste as a flavor base for stews, chili, or marinades, since it’s the most concentrated everyday source available.
For snacking, watermelon is your best non-tomato option. Pair it with a small handful of nuts if you want to boost absorption. Pink grapefruit at breakfast or guava in a smoothie made with yogurt or coconut milk also adds lycopene alongside a fat source. Since the pigment is stable through most cooking methods and doesn’t break down easily in storage, canned tomato products, jarred sauces, and frozen fruit all retain their lycopene content well.
