Lycopene In Tomatoes: What the Nutrition Research Shows
Tomatoes are a popular ingredient in many dishes, and they supply several useful nutrients.
Among those nutrients is lycopene, an antioxidant pigment. Lycopene and tomatoes go hand in hand, and in this section we look at what the research does and does not show about them.
Tomatoes provide vitamin C, vitamin K, potassium, fiber, and provitamin A carotenoids. Much of the research on tomatoes’ most significant health benefits focuses on their lycopene content.
Lycopene is a bright red pigment found in various fruits and vegetables, but tomatoes and tomato products supply most of the lycopene in typical Western diets.
Lycopene has been studied for its possible role in lowering the risk of chronic diseases such as cancer, heart disease, and diabetes. Most of this evidence comes from observational studies, which show links but cannot prove cause and effect, along with smaller trials and laboratory research on skin health and inflammation.
The Health Benefits Of Lycopene In Tomatoes
1. Antioxidant activity
Lycopene in tomatoes is an antioxidant. In laboratory studies it neutralizes free radicals, which may help limit oxidative damage to cells.
2. May reduce inflammation
Laboratory and small human studies suggest lycopene has anti-inflammatory effects and may lower some inflammatory markers, though results are mixed.
3. Supports heart health
A meta-analysis of observational studies (Cheng et al., Critical Reviews in Food Science and Nutrition) found that people with the highest lycopene intake or blood levels had about a 14% lower risk of cardiovascular disease and a 26% lower risk of stroke. These studies show an association, not proof of cause. Lycopene may also help protect LDL cholesterol from oxidation.
4. Potential cancer prevention
Some observational studies link higher lycopene intake or blood levels with lower rates of certain cancers, most consistently prostate cancer. The evidence for lung, stomach, and colon cancer is weaker, and these studies do not prove that lycopene prevents cancer.
5. May help protect skin
In a small 10-week study, adults who ate 40 g of tomato paste with olive oil daily had about 40% less skin reddening after UV exposure than a control group (Stahl et al., Journal of Nutrition, 2001). The effect is modest: lycopene does not replace sunscreen, and it has not been shown to prevent skin cancer.
6. May support bone health
Small studies suggest lycopene may reduce oxidative stress markers related to bone, but there is not enough evidence to say it lowers the risk of osteoporosis.
7. May improve sperm quality
In a 12-week randomized trial of 60 healthy young men, 14 mg a day of lactolycopene increased the share of fast-swimming sperm and sperm with normal shape, although its main measure (motile sperm concentration) did not change significantly (Williams et al., European Journal of Nutrition, 2020). Larger trials are needed, including in men with fertility problems.
8. May support eye health
Lycopene’s antioxidant activity has been studied in age-related eye disease, but human evidence is limited; lutein and zeaxanthin are the carotenoids best linked with eye health.
9. Immune function
Tomatoes provide vitamin C, which supports normal immune function. Whether lycopene itself improves immunity or lowers infection risk has not been shown in people.
10. May modestly lower blood pressure
A 2013 meta-analysis of six small trials (Li and Xu, Nutrients) found lycopene supplements lowered systolic blood pressure by about 5 mmHg on average, with larger effects at doses above 12 mg a day and in people whose blood pressure was already raised. The authors called for longer, larger studies. Lycopene is not a replacement for blood pressure medication; talk to your doctor before adding a supplement if you have high blood pressure.
11. Lung health
Lycopene’s anti-inflammatory effects have been studied in relation to lung tissue, but there is not enough human evidence to say it improves lung function.
12. Brain health
Researchers are studying whether lycopene’s antioxidant effects protect brain tissue, but there is not yet good evidence from human trials that it slows cognitive decline.
13. Liver health
Mostly animal and laboratory research suggests lycopene may reduce oxidative stress and toxin-related damage in liver tissue; human evidence is limited.
14. May help lower LDL cholesterol
A 2011 meta-analysis of intervention trials (Ried and Fakler, Maturitas) found that lycopene intakes of about 25 mg a day or more lowered LDL (bad) cholesterol by roughly 10%. Effects on HDL (good) cholesterol are less clear.
15. Blood sugar
Some animal and small human studies suggest lycopene may affect insulin sensitivity, but there is not enough evidence to recommend it for managing diabetes. People with diabetes should follow their care team’s advice.
16. Lycopene-Rich Foods
Other lycopene-rich foods include watermelon, grapefruit, and red peppers.
17. Lycopene Supplements,
Lycopene supplements are also sold, but food sources are generally preferred. In the US, the FDA does not approve supplements before they are sold, and supplements can interact with medications, so talk to your doctor or pharmacist before taking one, especially if you are pregnant, breastfeeding, or on regular medication.
Next time you’re at the grocery store, remember the many health benefits of tomatoes and lycopene. Tomatoes can be a useful part of a varied, balanced diet.
How much lycopene is in one tomato?
A medium-sized raw tomato (about 123g) contains around 3.2mg of lycopene, based on USDA data (about 2.6mg per 100g). The lycopene content can vary based on tomato ripeness, variety, and growing conditions.
What is the amount of lycopene in tomato paste?
Tomato paste is a concentrated source of lycopene. USDA data put canned tomato paste at roughly 29mg of lycopene per 100g (about 75mg per cup), compared with about 2.6mg per 100g in raw tomatoes. Tomato paste production removes water, concentrating the tomato solids and antioxidants, including lycopene.
How much lycopene is in one cooked tomato?
Cooking tomatoes makes their lycopene easier to absorb. USDA data list cooked red tomatoes at about 3.0mg of lycopene per 100g (roughly 7mg per cup), compared with about 2.6mg per 100g raw; the bigger gain is in how much your body absorbs. Heat breaks down cell walls, releasing more lycopene from the tissue.
How much lycopene is in tomato juice?
Tomato juice is a good source of lycopene, with about 22mg per one-cup serving of canned juice (USDA). Processing breaks down the tomato tissue, although juice keeps far more water than tomato paste.
How much lycopene is in tomato soup?
The lycopene content of tomato soup can vary based on the recipe, but USDA data list about 16mg in one cup of canned condensed tomato soup before water or milk is added. Homemade soups vary with how much tomato they contain.
How can you increase lycopene in tomatoes?
Choosing ripe tomatoes maximizes lycopene content. Cooking methods like roasting, sautéing, and steaming can increase lycopene bioavailability. Adding a little oil aids absorption; the Linus Pauling Institute notes that heating tomatoes in oil substantially improves lycopene bioavailability. Very long, high-heat cooking can break down some lycopene. Crushing tomatoes can also help release lycopene.
What is the lycopene content in a tomato?
USDA data put raw, ripe red tomatoes at about 2.6mg of lycopene per 100g. Actual amounts vary widely by variety, ripeness, and growing conditions.
How much lycopene is in sun-dried tomatoes?
Sun-dried tomatoes are a very concentrated source, with about 46mg of lycopene per 100g (USDA). The drying process removes water, concentrating the nutrients and antioxidants. Eating them with a little oil, such as oil-packed sun-dried tomatoes, improves lycopene absorption.
What is the lycopene content in tomato sauce?
Tomato sauce is a good source of lycopene, with about 14mg per 100g of canned sauce (USDA). Cooking and crushing tomatoes into a sauce helps release more lycopene from the cell structure. The concentration in a sauce also reduces water content.
Is lycopene in raw or cooked tomatoes more bioavailable?
Cooking tomatoes significantly increases the bioavailability and absorption of lycopene by breaking down cell walls. In one small study, tomato paste eaten with oil produced 2.5 times higher peak blood lycopene and about 3.8 times greater total absorption than fresh tomatoes eaten with the same oil (Gärtner et al., American Journal of Clinical Nutrition, 1997). Long cooking can reduce heat-sensitive nutrients such as vitamin C.
How much lycopene is in cooked tomatoes?
Cooking mainly increases how much lycopene your body can absorb. USDA data list about 3.0mg of lycopene per 100g of cooked red tomatoes, compared with about 2.6mg raw. Cooking helps release lycopene from cells.
What is the lycopene content in tomato ketchup?
Tomato ketchup contains lycopene, roughly 12-14mg per 100g, or about 2mg per tablespoon (USDA data; Linus Pauling Institute). Ketchup production involves cooking and concentrating tomatoes, which increases bioavailable lycopene levels. However, ketchup has high sugar content.
Conclusion: Lycopene In Tomatoes
Tomatoes are a nutritious food, and lycopene is one of the main reasons researchers are interested in them. By incorporating tomato-based products and recipes into your diet, you can enjoy the natural goodness of these antioxidant-rich fruits.
Observational research links higher lycopene intake with lower rates of some cancers, but this does not prove cause and effect, and more studies are needed. Tomatoes are a sensible part of a balanced diet.
Fresh tomatoes in salads and cooked tomato-based products are easy ways to include them in your daily routine. If you are considering lycopene supplements, talk to your doctor or pharmacist first.
A few tomato-based meals a week is a simple place to start.
FAQ about Lycopene In Tomatoes
What is lycopene?
Lycopene is a carotenoid antioxidant found in high amounts in tomatoes and some other red fruits and vegetables. It gives them their red color and is being studied for possible health benefits.
What are the benefits of lycopene?
Lycopene has been shown to have antioxidant properties, which can help protect cells from damage caused by free radicals. In observational studies, higher intake is linked with better heart health and lower rates of some cancers, and small trials suggest modest effects on how skin reacts to UV light. None of these findings prove that lycopene prevents disease.
How can I incorporate more lycopene into my diet?
One of the best sources of lycopene is tomatoes. You can enjoy fresh tomatoes in salads, sandwiches, or as a topping for pizzas and pasta dishes. Tomato-based products such as sauces, soups, and salsas are rich in lycopene.
Lycopene supplements are also available, but there is no official recommended daily intake, and in the US supplements are not approved by the FDA before sale. Check with your doctor before taking one.
Are there any side effects of consuming lycopene?
Lycopene from food is considered safe for most people, and no toxicity has been reported (Linus Pauling Institute). Less is known about long-term, high-dose supplements, and pregnant or breastfeeding women are generally advised to stick to food amounts.
Very high intakes can turn the skin orange (lycopenodermia), which fades after intake is reduced. It is always recommended to consult with a healthcare professional before starting any new dietary supplement.
Can lycopene prevent or treat cancer?
While lycopene has shown promise in some studies for its potential role in preventing certain types of cancer, more research is needed to understand its effects fully.
It is important to note that lycopene should not be used as a substitute for medical treatment, and individuals should follow their healthcare provider’s recommendations for cancer prevention and treatment.
Are lycopene present in tomato sauce?

How can you estimate the lycopene content in tomatoes?
USDA data put raw red tomatoes at about 2.6mg of lycopene per 100g and cooked red tomatoes at about 3.0mg per 100g, though amounts vary by variety and ripeness. Tomato products like sauce and paste are even more concentrated sources.
How many mg of lycopene in a tablespoon of tomato paste?
One tablespoon (about 16g) of tomato paste contains around 4.6mg of lycopene, based on USDA values. Tomato paste is concentrated, so it has higher levels per gram than raw tomatoes.
How many mg of lycopene are in a raw tomato?
A medium raw tomato (about 123g) contains around 3.2mg of lycopene (USDA; Linus Pauling Institute). The exact amount varies based on specific tomato variety, ripeness, and growing conditions.
How much lycopene is in one tomato?
A medium-sized raw ripe tomato (around 123g) contains approximately 3.2mg of lycopene. Cooking does not add lycopene, but it makes more of it available for your body to absorb.
How much lycopene is in a cherry tomato?
Cherry tomatoes contain lycopene too. A one-cup serving (about 150g) provides roughly 3.9mg, based on the USDA value for raw red tomatoes, so a single cherry tomato (about 17g) has around 0.4mg.
How much lycopene is in a glass of tomato juice?
In one cup (about 243g) of canned tomato juice, there is about 22mg of lycopene (USDA). Tomato juice is relatively concentrated in lycopene compared to raw tomatoes since it is made from processed tomato products. Amounts can vary based on specific preparation.
How much lycopene is in a Roma tomato?
A raw Roma (plum) tomato weighs around 62g in USDA data and contains roughly 1.6mg of lycopene, using the USDA average for red tomatoes. Cooking makes this lycopene easier to absorb.
How much lycopene is in canned tomatoes?
The lycopene content of canned tomatoes can vary slightly depending on the processing method. USDA data list about 6mg per cup of canned tomatoes packed in juice and about 10mg per cup of canned stewed tomatoes, compared with about 2.6mg per 100g of fresh raw tomatoes.
Is lycopene in raw or cooked tomatoes more bioavailable?
Cooking significantly increases the bioavailability of lycopene from tomatoes by breaking down cell walls. In one small study, total lycopene absorption from tomato paste was about 3.8 times higher than from fresh tomatoes when both were eaten with oil.
Is there lycopene in canned tomato sauce?
Yes, canned tomato sauce contains lycopene. Processing tomatoes into sauce at high heat increases available lycopene. About 1/2 cup of canned tomato sauce provides 10-15mg of lycopene.
Is lycopene a red pigment found in tomatoes?
Yes, lycopene is responsible for the red color of ripe tomato fruits and products. It is a carotenoid antioxidant that gives tomatoes their rich red pigmentation. Cooking helps release more lycopene from tomatoes.
What is the lycopene and beta-carotene content in tomatoes?
Tomatoes contain both lycopene and beta-carotene. Raw red tomatoes have about 2.6mg of lycopene and about 0.45mg of beta-carotene per 100g (USDA). Cooking with a little oil makes these carotenoids easier to absorb.
