Lycopene: a natural antioxidant

Lycopene is a vegetable pigment with antioxidant properties that gives some fruits and vegetables their red colour.It cannot be synthesised by the body and can therefore only be obtained through food.Chemically-speaking it is a carotene from the beta-carotene or provitamin A family.

Properties:

As it is a natural antioxidant that protects cells from oxidation and the ageing caused by free radicals,it has a preventative function in relation to cardiovascular diseases.

It can be beneficial in cancer prevention,especially prostate cancer.It also plays a role in protecting against macular degeneration,which is the main cause of blindness in those over 65 years of age.

It is also thought to reduce cholesterol,especially cholesterol that is bound to low density lipoproteins (LDL),more commonly known as “bad cholesterol”.

Dietary sources:

Being a vegetable pigment,it is found in vegetable foods with intense colours.Tomatoes and watermelon are especially rich in lycopene.Tomatoes are the food with the highest lycopene content,with up to 3,000 micrograms (mg) per 100 g.

Unlike other micronutrients (for example ascorbic acid or vitamin C),which are easily destroyed by heat or light,lycopene increases its capacity to be absorbed when ingested in the form of sauces,as the fat (for example,olive oil) facilitates its absorption.It is also thought that is absorbed better if eaten in the form of hot sauces.

It is believed that tomatoes grown in the sun and allowed to ripen on the vine in summer (the tomato is traditionally a summer fruit) are richer in lycopene than those grown in greenhouses,picked when green and ripened artificially in warehouses.Similarly,red tomatoes are richer in lycopene than green ones.

Some foods and dishes that are rich in lycopene include:

  • Tomato
  • Watermelon
  • Tomato sauce
  • Tomato juice and other juices
  • Gazpacho
  • Salmorejo (a cold soup made with bread, egg, tomato, peppers, garlic, salt and water)
  • Pipirrana (cucumber and tomato salad)
  • Pisto (a fried dish of peppers,tomatoes,egg and onion)
  • Ketchup
