High doses of lycopene—the crimson pigment in tomatoes—have been put to the take a look at to see if it may stop precancerous prostate lesions from turning into full-blown most cancers.
Back in Eighties, the Adventist Health Study found “strong protective relationships” towards prostate most cancers with rising consumption of legumes, citrus, dried fruit, nuts, and tomatoes. In the Nineties, a Harvard research focused consideration on tomatoes, which appeared to be “especially beneficial regarding prostate cancer risk.” Researchers suspected it is likely to be the crimson pigment in tomatoes known as lycopene, which has better antioxidant energy than a few of the different pigments, similar to the orange beta-carotene pigment in carrots and cantaloupes. Lycopene dramatically kills off prostate most cancers cells in a petri dish, even down at the ranges you may count on in your bloodstream after simply consuming some tomatoes. So, not surprisingly, the Heinz ketchup firm, together with producers of lycopene dietary supplements, petitioned the FDA to enable them to print well being claims on their merchandise.
As I talk about in my video Lycopene Supplements vs. Prostate Cancer, they have been primarily denied. The FDA stated the proof was “very limited and preliminary” and didn’t enable any endorsements for ketchup or dietary supplements. By that point, additional inhabitants research had cast doubt on the lycopene principle. Consumers of excessive dietary intakes of lycopene didn’t appear to have decrease most cancers charges in any case, however who has excessive dietary intakes of lycopene? Those who eat the most pizza. So, perhaps it’s no shock there are blended outcomes. What we wanted was to put lycopene to the take a look at.
It started with a case research of a 62-year-old man with terminal prostate most cancers. Both surgical procedure and chemotherapy had failed. He had metastases throughout that had unfold to the bone and was despatched to hospice to die. So, he took it upon himself to provoke “phytotherapy”—plant-based remedy. Every day, he took the quantity of lycopene present in 1 / 4 cup of tomato sauce or a tablespoon of tomato paste. His PSA, a measure of tumor bulk, began out at 365, dropped to 140 the subsequent month, after which down to simply 8 the month after that. His metastases began disappearing, and, “at last followup he was asymptomatic”—dwelling fortunately ever after.
When lycopene was given at a better dose in tablet kind, nonetheless, it didn’t appear to work. A 2013 evaluate of all such lycopene complement trials failed to assist the preliminary “optimism.” In reality, the researchers have been simply completely satisfied that the lycopene capsules didn’t find yourself inflicting extra most cancers, like beta-carotene capsules did. Then got here 2014.
Researchers in Italy had been giving the largest doses they may have of lycopene, selenium, and remoted inexperienced tea compounds to males with precancerous prostate lesions, hoping they may stop full-blown most cancers. But, in 2014, the expanded outcomes of an identical trial have been revealed, through which selenium and vitamin E dietary supplements resulted in extra most cancers. Yikes! So, the researchers in Italy stopped their trial and broke the code to unblind the outcomes. And certainly, these taking excessive doses of lycopene, inexperienced tea catechins, and selenium appeared to get extra most cancers than those that simply acquired sugar capsules.
“The potential implications are dramatic,” said the lead researcher, “given the current massive worldwide use of such compounds as alleged preventive supplementations in prostate and other cancers.” What went unsuitable?
Well, after the beta-carotene tablet debacle, researchers measured mobile injury at completely different pure and unnatural doses of beta-carotene, as you’ll be able to see at 3:32 in my video. At dietary doses, beta-carotene suppressed mobile injury, however at supplemental doses, that are larger, it not solely appeared to cease working, but it surely brought about extra injury. The identical with lycopene. “Both lycopene and [beta]-carotene only afforded protection against DNA damage…at relatively low concentrations”—at the sorts of ranges one may see in individuals consuming plenty of tomatoes or candy potatoes. That is, “levels [that] are comparable with those seen in the plasma [blood] of individuals who consume a carotenoid-rich diet.” However, at the form of blood concentrations that one may get taking capsules, “the ability to protect the cells against such oxidative [free radical] damage was rapidly lost” and, certainly, the presence of excessive ranges of beta-carotene and lycopene may very well serve to enhance the extent of DNA injury. It’s no marvel excessive dose lycopene capsules didn’t work.
Phytochemicals could be “guardians of our health,” however the security of consuming concentrated extracts is unknown. “The protective benefits of a phytochemical-rich diet are best obtained from frequent consumption of fruits, vegetables, and whole grain products”—by complete plant meals. The meals trade has completely different concepts, although. Soon, there could also be phytochemical-fortified bacon, martinis, and ice cream, says an article in the journal Food Technology. If they’ll discover simply the correct mix of plant compounds, it “is not inconceivable that foods that once contributed to illness and disease may be reconstructed…to offer significant health benefits.”

Instead of tomato-compound dietary supplements, what if we simply fed some most cancers sufferers some tomato sauce? That’s the topic of my video Tomato Sauce vs. Prostate Cancer.
