Food Science/canned cheese


Hello Mr. Polidori,
I hope you can help. Today I bought a can of cheese the spray kind Easy Cheese is the name. My son had never tried it and asked me to buy it. In the store the can I believe was fine and saw no dents. After we opened and ate it, my son notice two very small dents on the can, very small.  We didn't see them before and should I worry. I always remember hearing since I was small, never eat from a dented can. The cheese tasted fine actually good, and it says pasteurized on the can if that makes a difference. Should I be scared? Thank you.

Hi Carol,

Nope, a few dents in the can are not an indication of problems.  The only time you would be concerned about physical damage to a can is if it leaked or bulged.

If you have or find a can that looks like it is bulging please bring that can to the attention of the store manager.  A bulging can indicates that pressure has built up inside and that means something is growing in there!!

If gas escapes from a can or jar when you open it that is also a bad thing.  Jar tops usually have that indentation that pops out when you open it.  If pressure builds up inside the jar that depression will bulge out instead.

Now about eating that processed spray cheese.... try looking through the answers to other questions people have asked food science experts about processed foods and that will help you choose healthy foods for you and your family.

I happen to be at my sister's house and found a can of that spray cheese in her pantry.  Her husband is addicted to it and uses it on Cheese-Itz.  Wrong wrong wrong....  I keep telling him but he won't listen...  The processed foods are something we have become used to over the decades they have been available.  Since we seem to be fine and sated after eating them we have become comfortable with them.  But the problems they cause creep up on us.

Because they have lost a lot of their nutritive value we end up eating larger quantities as our bodies tell us we haven't eaten enough or gotten the right stuff (vitamins, minerals, phytonutrients, amino acids).  This helps to get us overweight (along with a lack of exercise common among us Americans).

Processed foods also contain the sugars and salts (needed to make this stuff taste good) and the big three - preservatives, artificial flavors and artificial colors that we should never put into our bodies.

It takes some effort to get this eating thing right, Carol, but if you make the effort to read about it online or purchase some books on the subject of eating right with whole foods you can get your family as healthy as they can be and help to protect the environment from the metal and plastic necessary to pressurize processed spray cheese.

A couple of other things to avoid; Genetically engineered foods and foods treated with radiation (irradiated foods). The best way to avoid both of those really big problems is buying organic, but that does add a lot to the food budget.  Irradiated foods are labeled, but the FDA is allowing the gene altered foods (GMO, Genetically Modified Organisms) into our supermarkets and onto our plates by not labeling them.

I hope you are already doing the whole food thing and this spray cheese is just a one time snack experiment.

Hoping you and yours are healthy,
Please ask follow-ups if you want to,

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!
