is tomatoe sauce better for you then a fresh tomatoe?

Hi Craig,

There are studies out that support the value of tomato sauce in keeping your heart healthy and in reducing your chances of prostate cancer.  And these studies reportedly compared the effects of raw tomatoes vs tomato sauce.

There is still work to be done as they have not determined what substances are responsible for this statistical result.  Does cooking a tomato release chemicals that we normally wouldn't have access to?  Is it the combination of ingredients in the sauce that has some effect?  Will a larger study correct an aberration in data?

We simply don't know yet.

Another problem is that in one study the subjects were rats that had prostate cancer induced in them.  Animal studies do not normally correlate well with human results, but are allowed by the FDA to be used as a guide because it keeps costs down while providing a "sense" of safety in that science is being used!!! That doesn't really make much sense, but that's the kind of rules we get when corporations are allowed to influence the agencies of the government that regulate them.

If you want to make a life choice, I would stick to whole foods and organic foods with minimal processing/cooking.

I would be skeptical of any studies that support health benefits of a highly processed food such as tomato sauce.  As far as flavor is concerned, being Italian, I love the stuff, and do enjoy it occasionally.  However, we know that processing and/or cooking destroys many of the nutrients that we need.  I would never trust processing to make things healthier, just tastier.  Ordinarily healthy and tasty foods will taste bland if you "BAM!!!" your taste buds with highly spiced or artificially flavored processed foods.  Develop your taste buds by eating healthy.

Hi again Craig,

While reviewing my answers, as I do occasionally, I have a correction to make. Tomato products that are canned DO contain greater amounts of nutrients than fresh tomatoes bought at your average grocery store.
The reason is that canning and processing facilities are usually built close to regional farming areas. The short trip to processing allows tomatoes to be picked at their ripest and most nutrient rich (and tastiest).
Tomatoes you purchase in most grocery stores are picked when green then artificially ripened while on their way to market.

The benefit of processed tomatoes doesn't have an advantage over farmer's market tomatoes (again preferrably organic, for BOTH types of products) or some grocery store tomatoes which are local-farm fresh.

Thanks again for your question,
Michael Polidori

I can answer questions about food safety issues and benefits vs risks issues related to the growing, environmental effects and health effects of conventional, organic and gene altered food (GE GMO genetically engineered), both plants and animals. I can answer questions related to the cause and treatment of nutritionally related disease (including immune related diseases) and nutritional problems related to healing physiological or nutritional injuries.


I have been studying food growing methods, regulatory rules and organic/conventional/biotechnological methods of producing foods since 1998. I have prepared materials for distribution concerning health safety issues, lack of regulation, environmental dangers and industry sponsored research of genetically engineered plants and animals. I have also created similar materials promoting the benefits of organic agriculture for not only direct health benefits but for dramatic reductions in pollution, indirectly benefitting our health. I have prepared research materials for and participated in Public Television talk and radio shows regarding the issues surrounding genetic engineering and organic foods and debated in college forums with mainstream scientific experts about the safety & regulatory issues of gene altered foods. 2000-2002 I managed booths at major North Carolina events interfacing with the public (including farmers) on organic vs GMO benefits and dangers. I understand regulatory practices, shortcomings & revolving jobs doors of the FDA, USDA and EPA and the industries they regulate. I have been involved in nutrition, health care, prescription drug, vaccine, disease, immune and wellness issues since 1997 reading and writing on the internet and in practical applications with myself, family and friends leading to paths of health, wellness and fitness.

No Degree, but some college in the sciences (Biology, Chemistry, Calculus, Astronomy and Physics). I have also taken several courses in Logic and Philosophy. I am involved in extensive research using mainstream websites (many of which I am on mailing lists for) such as - peer-reviewed publications (The Lancet, New England Journal of Medicine, others), PubMed database of research studies, National Institutes of Health, FDA, USDA, EPA, University Research libraries, hospital databases (John Hopkins, Mayo Clinic, Cleveland Clinic, others). I also regulary contact/correspond-with manufacturers/suppliers of food products, pharmaceuticals (including vaccines) and supplements with questions, recommendations, criticisms and complements. Every week, I learn something new!
