Tomatoes, however, are the richest source of lycopene, and cooked tomato products, such as tomato paste, spaghetti sauce and pizza sauce, provide much higher amounts of the phytonutrient compared with fresh tomatoes or tomato juice.
Spaghetti sauce also contains olive oil, an added benefit that makes this particular food product an extremely good choice as a source of lycopene. That's because the oil assists in the body's absorption of the nutrient.
Many studies have shown a correlation between a high consumption of tomato products and a decreased incidence of prostate cancer. A diet rich in lycopene derived from tomato-based products can reduce the risk of prostate cancer by approximately 40 percent.
