Preserves contain an industrial chemical that we ingest through food
There has been a debate for a long time about how much of the industrial chemical bisphenol A (also known as BPA) is in cans and whether this poses a health risk. For more than forty years, BPA has been used in consumer products such as the inner lining of cans and preserves. This is to prevent corrosion and metal breakage. Researchers have now found that eating canned foods can put BPA on our bodies.

In general, nutritionists recommend fresh foods. An additional argument against canned food is the industrial chemical bisphenol A (BPA). Numerous studies have shown that the chemical is harmful to our health. Now, scientists from Stanford University School of Medicine found in a new investigation that consuming canned food leads to our body being burdened with BPA. The experts published the results of their study in the journal "Environmental Research".

Soup and canned pasta are particularly stressed
Do you often eat soup or canned ravioli? If so, you could expose your body to a health hazard. The new investigation found that these foods lead to a higher concentration of BPA than, for example, cans with vegetables and fruit, the experts say. Cans with drinks, meat and fish do not result in a higher BPA concentration among consumers.

Canned foods contaminate our bodies
Knowing the possible BPA intake can help consumers in the future if they have to decide which canned goods or cans to buy. Consuming canned food is one of the highest exposure routes to BPA, the scientists explain. The study shows that canned food continues to be a source of BPA contamination. Basically, packaging materials can become a food problem. For example, it was only recently discovered that mineral oil is contained in food packaging, which can be transferred to the food and lead to stress for consumers. Mineral oil residues can also endanger our health.

Study examines almost 8,000 subjects
The current study included over 7,669 subjects. All test subjects were six years or older and were examined between 2003 and 2008 as part of the "National Health and Nutrition Examination Survey". The scientists were able to determine what everyone had eaten in the past 24 hours and whether there was an increased concentration of BPA. The researchers took a urine sample on the same day. An increased BPA concentration in the urine is clear evidence of a BPA exposure, explains lead author Jennifer Hartle from the Stanford University School of Medicine.

Consuming canned food leads to a significantly increased concentration of BPA
If subjects had eaten canned food in the past few days, they had a 24 percent increase in urinary BPA compared to people who had not consumed canned items. Eating two or more canned foods even led to an approximately 54 percent increase in BPA levels, doctors warn.

Can soup increases BPA particularly drastically
As soon as the researchers evaluated the types of canned food consumed, they found that canned soup increased BPA levels by up to 229 percent. Canned pasta led to an increase of 70 percent, for canned vegetables and fruit the value was 41 percent. Eating a single can of cream of mushroom soup will add more BPA than eating three cans of peaches, for example, says lead author Hartle. According to the researchers, this could have to do with the fat content or the heat that is required when processing the soup.

BPA can mimic hormones and lead to health problems
The scientists continued to test whether the BPA exposure found was a health risk. BPA could disrupt the normal functioning of hormones in our body, for example it can mimic the response of hormones. It can then reprogram cells, which can lead to a variety of health problems, the researchers say. An increased exposure to BPA is associated with many negative effects, such as rising blood pressure, diabetes, obesity and cardiovascular diseases, the authors explain.

What is the maximum amount of BPA we should consume per day?
Although different thresholds for safe BPA dosing are set worldwide, the researchers believe exposure to BPA should never exceed 50 micrograms per kilogram of body weight per day.

According to the FDA, our food packaging is safe
The Food and Drug Administration (FDA) has conducted extensive research and reviewed hundreds of studies on the safety of BPA. The currently approved uses of BPA in food packaging in the US are safe, FDA spokeswoman Lauren Sucher said in a statement to the CNN news channel. However, it is possible for people to reduce their exposure to BPA by purchasing fresh, unpackaged food, the spokeswoman added. (as)
