Let us all think for a moment, how is it possible that fresh tomatoes has a shelf life of 1 – 2 weeks while canned tomatoes have shelf life of over a year? The answer is simple, there is something special about the cans being used that allows the tomatoes to be preserved for over a year; but what is that something and more importantly is it safe for our body?
For years, the chemical bisphenol A (BPA) – commonly found in plastic bottles, can linings and other products – has been linked to a number of negative health consequences, and now a new study has indicated that even in small doses BPA can cause significant changes in metabolism as well as affect the reproductive and nervous systems. Indeed, it is the the chemical bisphenol A (BPA) that preserves the tomatoes for a long period of time.
Many studies have linked BPA to obesity, breast cancer, infertility in both males and females, early puberty, heart disease and nervous system damage. BPA disrupts the endocrine system (relates to glands which secrete hormones and other products directly to the blood), mimicking the hormone oestrogen (group of steroids hormones which promotes the development and maintenance of characteristics of the female body). BPA (endocrine disruptor) upset the hormonal balance and can stimulate the growth of tumours in the breast, uterus or prostate. They can affect fertility, pregnancy, and worse, can affect the foetus by interfering with testosterone, disrupting normal sexual development. This disruption is not often apparent until adulthood and includes the increased risk of cancer.
One solution to this would be BPA-free cans, but have you ever seen a BPA-free can on a store shelf? Only a few companies uses BPA-free cans for instance Eden in the US. Studies have shown that some cans labelled BPA-free still contains a very minimal dose of BPA; crazy world isn`t it? Another reason why it will take a very long time to see more and more BPA-free cans on the market is because there are already a lot of BPA cans in the store and until the inventory depletes they would not even care putting the BPA-free cans on the shelves!
The other solution, which is the simplest one, is to buy and eat fresh food like fresh tomatoes, beans or peas. Who wouldn`t love to eat fresh food? But we are living in a world where people go to the supermarket only a few times and buy a large number of canned food for the month that will last rather than buying fresh food when needed. Its all a matter of perspective.
