• Just five days of eating canned soup dramatically increases levels of hormone-mimicking bisphenol A

A hormone-mimicking chemical used in soup tins could increase your risk of heart disease and diabetes, scientists have warned.

Eating canned soup every day for just five days caused a 1,000 per cent increase in levels of bisphenol A in the body, they found.

Scientists blame this increase on manufacturers using BPA in the lining of soup tins to prevent them from rusting.

BPA is an organic compound that can mimic the body’s own hormones and previous research has warned it can increase the risk of illnesses including heart disease, diabetes and obesity.

It is known as the gender-bending chemical, after previous studies showed it can interfere with the way hormones are processed.

But scientists are split over its effects, with some maintaining it is perfectly safe and others linking it to cancer, obesity and diabetes.

BPA is also used to line other metal food containers polycarbonate bottles and some products used in dental surgeries. It has been banned from baby bottles in the EU.

The team, from the Harvard School of Public Health in Boston, Stati Uniti d'America, studied how eating tinned sound affected the BPA of a group of volunteers.

They split 75 staff and students into two groups, one of which was ate a 350ml tin of vegetable soup daily for five days, while the other ate an identical-sized portion of vegetable soup made only with fresh ingredients.

After leaving their system to cleanse itself for two days, both groups swapped places. Results, published in the Journal of the Medical Association, showed BPA levels in urine samples of volunteers who’d just finished the tinned soup trial were over 1,200 per cent higher than those collected after the fresh soup trial.

Study author Jenny Carwile, a doctoral student at Harvard, claimed the increase could be temporary and that more research is needed.

Ha detto: ‘Previous studies have linked elevated BPA levels with adverse health effects.

‘The next step was to figure out how people are getting exposed to BPA. Ci conosciamo da un po 'che bere bevande che sono stati conservati in alcune plastiche dure in grado di aumentare la quantità di BPA nel vostro corpo.

'Questo studio suggerisce che gli alimenti in scatola può essere una preoccupazione ancora maggiore, specialmente dato il loro ampio utilizzo.’

Co-autore il professor Karin Michels aggiunto: 'L'entità della crescita in BPA urinario abbiamo osservato dopo appena una porzione di zuppa era inaspettato e può essere motivo di preoccupazione tra gli individui che consumano regolarmente alimenti da lattine o bevono diverse bevande in lattina al giorno.

'Può essere consigliabile per i produttori a prendere in considerazione l'eliminazione BPA da rivestimenti di lattine.’

Food Standards Agency del Regno Unito ha detto: ‘Our current advice is that BPA from food contact materials does not represent a risk to consumers but the agency will be looking at this study, as it would at any new pieces of work, to see if it has any implications for our advice to consumers.

‘The FSA bases its advices on the body of scientific evidence and the opinion of independent scientists.’
