“Here’s the advice: Don’t ever buy any kind of peanut butter in plastic containers.
“Even organic peanut butter should not be bought in plastic containers.”
Rubin said her colleague Lee Hitchcox originally wrote about the potential dangers in his book, Long Life Now: Strategies for Staying Alive.
She said the concerns stem from the way that peanut butter is processed before its placed in plastic jars.
“Most of the peanut butter on the grocery store shelves (even in many ‘natural foods’ stores) already contains pesticide and/or fungicide residues, tons of sugar and a host of other additives,” she claimed.
“Peanut butter must also be heated to flow through the machinery for it to be quickly, easily and consistently poured into jars (plastic jars are also often then heat-sealed – the sealing of the combination foil-type/plastic barrier that is usually found under the lid for food safety reasons.)
“The concern is that the now hot oils/fats in the peanut butter help the plasticisers (in the plastic jars and lids) leach into the food, and along with all the other chemical residues and additives, make for an incredibly toxic product.
“The plasticisers bond to the oil in the peanut butter as a result of the packaging process.
“The consumer is then eating plastic… which is why peanut butter packed in plastic is one of the most toxic foods you can purchase.”
As a result, Rubin says she only buys peanut butter in glass jars – and implores others to do the same.
Rubin has also released details of results from plastic peanut butter testing, and says her claims are backed up by the findings.
