No more canned foods

If you haven't already caught the news, it's time to eliminate canned foods and exposure to plastics that contain the chemical, bisphenol A (BPA). A worrisome and unexpected association has been found with not cancer or behavioral problems, like most of the previous studies have done on BPA... no... this time it's...

heart disease, diabetes, and even liver disease!

The study comes from the Journal of the American Medical Association by Dr. Iain Lang and associates at the University of Exeter, UK, and the University of Iowa, and it's a very convincing study involving a relatively broad sample of adult Americans.

Their study, released on Sept. 17, 2008, "Association of urinary bisphenol A concentration with medical disorders and laboratory abnormalities in adults", persuasively demonstrated a 40% increased incidence of coronary heart disease, heart attack, and diabetes with increasing exposure to BPA (as judged by urine levels) among the nearly 1500 adults aged 18-74 years. People with coronary heart disease had double the blood level of BPA compared to those without. In addition, higher urine levels of BPA were associated with abnormalities of two liver tests, GGT and alkaline phosphatase (ALP).

So, for me at least, and maybe you too:

1 No more tin cans (which are heavily lined with BPA polymers). Especially canned acidic foods, such as tomato products, because they can accelerate leaching of BPA from the linings.

2. No more hard plastics labeled with recycling code #3 or #7, nor polycarbonate water bottles, the hard ones, often brightly colored. (Soft, cloudy plastics with code #1, #2, or #4 are safe because they are not made with any PBA.)

3. No more "microwaveable-safe" plastics because they may actually mean human-unsafe, as highlighted by this damning assurance from Tupperware that BPA is not a health hazard.

4. Use only glass, porcelain or stainless-steel containers, particularly for hot food or liquids.

5. Use baby bottles that are BPA-free, although in the past year, most major manufacturers have thankfully gotten the message and have developed bottles made without BPA.

I feel for you, man. Ugh, that really sucks. Well, I've always tried to eat healthy and fresh. I guess I'm just going to have to do more than try.

Would you say canned Tuna might be an issues, as well as canned chicken?

Yeah I'm interested in this as well...I use a ton of canned tuna and sometimes canned chicken for sandwiches.

AFAIK, all cans have a thin, hard plastic inner lining that contain PBA. But, it gets worse...

.... after the food is hermetically sealed in a can, by law, the finished product must be "pasterized" in order to kill any bacteria that may have found its way into the can. This exposure to high heat may possibly accelerate the leaching of BPA into the food.

UPDATE:
An organization called Environmental Working Group (EWG) appear to have actually done a small study on PBA's in canned foods. They collected 97 varieties of canned consumables found in popular grocery chains. [EWG appear to be located in D.C. and California.]

They found that 46% of all canned foods in their study had some levels of PBA's, with 11% having unsafe levels. 33% of infant formulas had PBA's, all having unsafe levels for infants. Pasta products (like Ravioli) were 100%, with 33% having unsafe levels. Vegetables 35%-29%, soups 90%-11%, beans 50%-0%, tuna 50%-0%, fruit 24%-0%, meal replacement drinks 40%-20%, soft drinks 17%-0%, milk 0%.

The charts to their study can be found here: ewg.org
 
Only thing I eat out of cans is spam, some kind of fish and beans. All about once or twice a week.

I'm more concerned about the frozen foods I eat 7 times a week...

Where do you have proof that canned foods have BPA in them? Secondly, I don't really know of many tin cans, I do know of cans that are made of steel with what appears to be no inner lining. I've seen cans with some sort of white liner, is that what you're referring to?

It has been common knowledge that food cans have inner plastic linings made with BPA. Did you read the whole thread? It's not that long.

Some canneries have come out themselves and said that they use plastic w/BPA. Many cans may look like they have no plastic lining, but if you look closer you'll usually find a very hard, very thin, relatively clear layer of plastic covering the inside of the can. Try using a sharp knife to scatch the inside of the can and you'll notice it clearly. And yes, with some, the plastic lining is white.

AFAIK, most food cans are indeed not actually made of tin anymore. They're made of a much more inexpensive non-stainless steel with an inner liner to prevent odor, taste, and metal transfer.

Well for my Campbells select soup, the only plasitc lining I could find was where the two pieces of steel meet; it does not line the entire can. I have seen cans with the whole interior lined with plastic though.
 
I drink 4-8 cups of tea a day from a food-grade plastic tea-maker. I also microwave the water in said tea-maker. If there was any BPA in it, then it's long been processed out of my system and levels should be at an all time low now.

I also notice that the results of the study are in ug/kg of body weight. So the bigger you are, the less you ave to worry about. That, and they give no context for their results, using vague terms like "permanent damage". Obviously that's never a good thing, but if they knew anything concrete they should be specific. Are my testicles going to become necrotic? Will it sterilize me?

That, and these are animal studies. There are plenty of clinical trials for medications that work on animals, but prove completely useless when it comes to treating humans. When there's a human trial that shows results, I'll take it seriously.

That, and according to their own results, many canned foods are actually safe.
http://www.ewg.org/node/20936 (see second chart)

None of the cans of tuna, fruit, beans, soda, or milk products tested have anything other than a dose "within a margin of 100 from a harmful dose". From what I can tell, that's a pretty big margin, and that's one serving. Meaning I'd have to eat 100 cans of any of the above to get any harmful effects.

In short, this looks more and more like yet another alarmist study to me.
 
Doesn't water come through plastic PVC pipes to our taps? I'm betting everyone would have cancer if this was completely true...

I'm not sure that PVC has BPA in it. Many plastics do not.

Most residential water supply lines are copper.
 
This just in:

Studies show that living life is a leading cause of death. 😛


What these days won't cause you cancer/kill you?

Exactly.

Next.
 
..I hear microwave pop corn is loaded w/all kinds of chemical stew due to the teflon/plastics/high temps.

It is also loaded full of delicious.

Mmm, so true. All of us here at H&F are all fatties at heart.
