Tomato

Tomatoes are easy-to-use produce staples that fit naturally into anti-inflammatory meals. They are commonly discussed for lycopene along with vitamin C and their role in salads, soups, sauces, and vegetable-forward home cooking.

Quick answer

Tomatoes are the primary dietary source of lycopene, a carotenoid pigment that gives them their red color and has been extensively studied for its antioxidant properties. Cooking tomatoes with olive oil significantly increases lycopene bioavailability.

What it is

Tomatoes (Solanum lycopersicum) are fruits botanically but used as vegetables culinarily. They originated in western South America and were domesticated in Mexico. They are available fresh, canned (whole, diced, crushed, paste), sun-dried, and as juice and sauce.

Tomatoes are fundamental to Mediterranean, Italian, Mexican, and Indian cuisines. They are used in sauces, soups, salads, salsas, and as a base for countless dishes. Canned tomatoes are often more nutrient-dense than off-season fresh tomatoes because they are processed at peak ripeness.

Why tomatoes may support an anti-inflammatory diet

Lycopene is a fat-soluble carotenoid that is one of the most potent singlet oxygen quenchers among common dietary antioxidants. Unlike beta-carotene, lycopene is not converted to vitamin A, and its primary studied role is as an antioxidant. Cooking breaks down cell walls and increases lycopene bioavailability by 2-3 times compared to raw tomatoes.

Consuming lycopene with fat (such as olive oil) further enhances absorption because it is fat-soluble. This is why Mediterranean-style tomato sauces cooked in olive oil are considered one of the most bioavailable sources of lycopene.

Tomatoes also provide vitamin C, potassium, and folate. The combination of lycopene with vitamin C provides both fat-soluble and water-soluble antioxidant coverage.

Key nutrients and compounds

A 100g serving of raw tomato provides approximately 13mg vitamin C (14% DV), 237mg potassium (5% DV), 1.2g fiber, and 2.6mg lycopene. Cooked tomatoes and tomato paste are more concentrated — 100g of tomato paste provides approximately 29mg lycopene. Canned tomatoes provide about 9mg lycopene per 100g.

Potential health benefits

Primary dietary source of lycopene, one of the most studied dietary antioxidants

How to eat tomatoes

Make a simple tomato sauce with canned tomatoes, garlic, olive oil, and basil
Roast cherry tomatoes with olive oil at 200C until blistered for a quick side
Add tomato paste to soups, stews, and grain bowls for concentrated lycopene
Slice fresh tomatoes with olive oil, basil, and salt for a classic side
Use sun-dried tomatoes in salads, pasta, and sandwiches
Make gazpacho with raw tomatoes, cucumber, pepper, and olive oil

Shopping and storage

For lycopene, canned tomatoes and tomato paste are often better choices than fresh because they are processed at peak ripeness. Choose canned tomatoes without added sugar. Store fresh tomatoes at room temperature for best flavor — refrigeration reduces taste and texture quality.

FAQ

Are cooked tomatoes healthier than raw?

For lycopene specifically, yes — cooking increases bioavailability by 2-3 times. However, raw tomatoes retain more vitamin C. Both forms have value, and a mix of cooked and raw tomato consumption is ideal.

Is tomato paste better than fresh tomatoes?

Tomato paste is the most concentrated source of lycopene, providing about 10 times more per gram than fresh tomatoes. Even small amounts (1-2 tablespoons) added to cooking provide meaningful lycopene intake.

Do I need to eat tomatoes with fat?

Lycopene is fat-soluble, so consuming tomatoes with a source of fat (olive oil, avocado, nuts) significantly improves absorption. This is why Mediterranean-style tomato sauces are particularly effective.

Can tomatoes cause inflammation in some people?

Some people with nightshade sensitivities report that tomatoes worsen joint symptoms, but this is not well-supported by clinical evidence for the general population. If you suspect a sensitivity, try an elimination period and reintroduction.

Evidence note

Lycopene has been studied in numerous epidemiological studies and clinical trials. Observational data consistently associates higher tomato and lycopene intake with lower levels of inflammatory markers. Intervention studies using tomato products have shown reductions in CRP and other biomarkers, though results vary by population and dose.
