Tomatoes taste good but don’t prevent cancer:
“But after a painstaking analysis of 145 studies, the agency concluded there’s no scientific evidence of any cancer-fighting benefit from lycopene and only limited evidence for any benefit from tomatoes themselves. (See FDA Tomato Ruling May Make Pizza a Health Food)”
“All of the 81 observational studies of lycopene and cancer were rejected as failing to meet the scientific standards for a claim of a cancer prevention benefit, Dr. Kavanaugh and colleagues said.”
By all means continue to eat tomatoes but you can stop those supplements with lycopene. There is not a shred of evidence that they prevent anything.
