Stainless Steel Stents and Cookware May Cause Problems

Contrary to common beliefs, stainless steel may not be the most inert substance. A new study has found that stainless steel coronary stents may trigger allergic reactions to substances such as nickel, molybdenum, or chromium, which are released. These allergic reactions may be a major factor in causing in-stent restenosis.


The researchers looked at 131 patients (avg. age 62 years) with coronary stainless-steel stents who underwent angiography for suspected restenosis. The average time since the stents were inserted was about 6 months.

All patients underwent allergy skin tests for nickel, chromate, molybdenum, manganese, and small stainless-steel plates.

In-stent restenosis (50% diameter stenosis) occurred in 89 patients.

All ten patients with positive patch-test results had restenosis (4 had positive reactions to molybdenum and 7 patients had positive reactions to nickel)
The authors conclude that "Allergic reactions to nickel and molybdenum released from stents may be one of the triggering mechanisms for in-stent restenosis."

Lancet 2000; 356: 1895-1897

Dr. Mercola's Comments:

Stainless steel may not be the most inert substance to use. This study, which is clearly not related at all to cooking, does show that sensitive individuals can have adverse reactions to stainless steel devises placed into their body for coronrary artery disease.


As far as stents go, the best thing to do is to avoid them in the first place. One of the best ways to do so is to follow the food choice recommendations, get proper exercise, and get plenty of sleep.


What most physicians do not realize is that nickel is every bit as toxic as mercury and some physicians believe that nickel is actually more toxic than mercury. Nickel comes from a German word for malicious or capricious spirit, sometimes meaning the devil.


It is well known from the literature that some of the ions which are released from these devises are able to destroy or damage enzymes and proteins, in addition to causing allergic reactions.


Clearly there is a quantitative element involved and I can not begin to guess how many nickel ions are liberated during the cooking process with stainless steel cookware. Clearly this is better than aluminum, which should be definitely avoided. The best cookware would be ceramic-coated metal as the ceramic is virtually inert and will not transfer any metal ions to the food you cook.


If you use Teflon coated cookware, you should be aware that there is some evidence that fluoride can be released. Plan on discarding most all Teflon coated cookware after about one year of regular use. As soon as a scratch develops on the surface this cookware will start to leach aluminum as that is the typical metal used beneath most Teflon coated cookware.

Stainless steel alloys all contain nickel, chromium, molybdenum, iron, carbon, and various other metals. In addition, higher temperatures will always increase the rate of leaching. Unfortunately, I don't know of any studies on this subject.

However, contact time has to be considered as well. The stents are in place inside the body and subjected to an environment that will solubilize almost anything, where the cookware is only subjected to any given batch of food for a very short period.

Dr. Ray Peat is the biochemist who helped Dr. John Lee understand natural progesterone. According to Dr. Peat, there are two kinds of stainless steel -- one kind is attracted to magnets, the other kind is not. You want to buy only the magnetically-attractive type of stainless steel, which apparently has a very low nickel content and does not leach nickel into food.

Here is some additional evidence of the fact that magnetized steel is safer. The following two links http://www.chenbros.com.tw/page13.htm
http://www.chenbros.com.tw/page14.htm
are from a company that produces stainless steel cookware and clearly demonstrates that then magnetized version has no nickel. Nickel is likely more toxic than mercury and the main reason for concern with stainless steel cookware.

Lastly, the pH of the food has an impact as well. A more acidic food may leach more from the cookware.

Even more information on stainless: [bolded words - mine]

I copied this article from EMSL newsletter EMSL Analytical Times Summer 2007 emsl.com

"Understanding the Dangers of Hexavalent Chromium

Hexavalent chromium [CR(VI)] compounds are a group of chemical substances that contain the metallic element chromium in its positive-6 valence (hexavalent) state. Occupational exposures to Cr(VI) occur during the production of stainless steel, chromate chemicals, and chromate pigments. These exposures also occur during other work activities such as stainless steel welding, thermal cutting, chrome plating, painting and coating processes.

Stripping and painting of aluminum surfaces, such as aircraft fuselages and aluminum castings are of particular concern due to widespread use of zinc chromate primers, which have ‘etching’ properties that enable better paint adhesion. These primers are also finding increasing application on galvanized steel products, including automobiles.

NIOSH considers all Cr(VI) compounds to be potential occupational carcinogens. An increased risk of lung cancer has been demonstrated in workers exposed to Cr(VI) compounds. Other adverse health effects associated with Cr(VI) exposure include dermatitis, occupational asthma, nasal irritation and ulceration, perforated nasal septa, rhinitis, nosebleed, respiratory damage, perforated eardrums, kidney damage, liver damage, pulmonary congestion and edema, epigastric pain, and erosion and discoloration of the teeth.

Cr(VI) compounds vary in solubility from those that are readily soluble to those which are practically insoluble in water. In 1975 NIOSH documented the carcinogenic effects of water-insoluble Cr(VI) compounds. The NIOSH 1988 testimony to OSHA on the air contaminants standard recommended that all Cr(VI) compounds, regardless of their degree of solubility in water, be considered occupational carcinogens. NIOSH is currently reviewing and evaluating the available information on Cr(VI) compounds including the toxicology, health effects, industrial hygiene, and analytical chemistry literature in order to update its 1975 criteria documented on Cr(VI)."
