Eat More Red: Liking Lycopene

Red TomatoRed, orange and yellow colors in vegetables and fruits derive from pigments called carotenoids.  Carotenoids represent a variety of antioxidants and phytonutrients (phyto from the word plant).    

One of the most common red carotenoids is lycopene.  Lycopene is a key carotenoid in a healthful diet. Foods high in lycopene are linked to lower risks of certain types of cancer and improved eye and heart health.  Some research also indicates that lycopene is associated with reduced build up of plaque in the arteries (atherosclerosis.)

Vegetables highest in lycopene are red tomatoes, particularly sun-dried tomatoes. When foods containing lycopene are heated or mechanically processed, the lycopene’s bioavailability increases so that your body can make more use of it.  For example, sun-dried tomatoes have more than 16 times the lycopene than raw tomatoes for the same quantity by weight.

The table below shows the different amounts of lycopene measured in micrograms per gram.  Even though some of the foods are very high in lycopene, you may not want to eat large amounts of these foods.  While tomatoes have only 2,767 mcg and Russian dressing has 3,576 mcg of lycopene, this is equal to eating one tomato at 30 calories compared to 7 tablespoons of dressing at 355 calories.  Better to just eat 2 tomatoes and save nearly 300 calories to get the same amount of lycopene.  Be aware also that there are many colors of tomatoes, but only red tomatoes have measurable amounts of lycopene.  Use the following table to help your body get the lycopene it needs and eat more red!
