Tomato benefits: cooking is what gets lycopene into you

Cooked beats raw here. Heat multiplies how much lycopene your body can actually absorb.

Published May 19, 20261 min read

Most vegetables lose nutrients when heated. Tomatoes are the exception. Lycopene sits locked inside cell walls, so little of it is absorbed from a raw tomato.

Cooking breaks those walls down and converts lycopene into a more absorbable form. That is why tomato sauce and paste outperform fresh tomatoes on lycopene uptake.

Key benefits

  1. Lycopene is a powerful antioxidant

    The carotenoid behind the red colour measures higher than beta-carotene in free-radical scavenging capacity. Observational studies repeatedly find lower cardiovascular risk among people with higher blood lycopene.

  2. Prostate health is its most studied association

    Several cohort studies report lower prostate cancer incidence in populations consuming more tomato products. It is too early to call it causal, but it is the most consistently repeated observation.

  3. Potassium helps excrete sodium

    237 mg per 100 g at just 18 kcal. You can eat a lot without energy cost, which makes tomatoes a practical potassium source in a salty diet.

  4. It may add to your skin's UV resistance

    Small trials found less UV-induced redness after ten or more weeks of eating tomato paste. It does not replace sunscreen.

How to eat it well

  • Cook them in oil. Lycopene is fat-soluble and heat-stable; sautéing in olive oil raises absorption substantially.
  • Processed forms are a genuinely good choice. Tomato paste and canned tomatoes are more concentrated in lycopene than fresh.
  • Keep the skin on. Lycopene concentrates near it.
  • Refrigeration ruins the flavour. Cold damages the aroma compounds, so store at room temperature and cook them.
  • Riper means more lycopene. The redder, the better.

What to watch out for

  • With acid reflux, the acidity can worsen symptoms.
  • Tomatoes are nightshades, and related allergic reactions occur rarely.
  • Very large intakes sustained over months can turn skin orange (lycopenemia). It is harmless and reversible.
  • Many commercial tomato juices and sauces are high in sodium — check the label.

Beet nitrate converts to nitric oxide, which widens blood vessels. That is why it keeps appearing in exercise physiology studies.

There is a reason cabbage juice became a folk remedy for stomach trouble. The evidence, though, is weaker than its reputation suggests.

Onion's antioxidant quercetin concentrates in the outer layers. Peeling two extra layers out of habit throws much of it away.
