Where are the studies that show that food without
preservatives are healthier that foods with?
------------------------
It depends what the preservatives are, doesn't it.
Lemon juice is a preservative (a natural one, mind)
and clearly no one has a problem with lemon juice from
a health perspective. But I thought there was some
quite convincing studies suggesting that processed
foods (as a whole) increase the chance of certain
cancers.
When it comes artifical preservatives vs natural
preservatives, I think the issue is that we know that
natural preservatives are safe from thousands of years
of use, compared to a lack of definitive knowledge about
the safety of certain artificial preservatives.
For example, butylated hydroxyanisole has been shown
in more than one study to cause cancers in certain
animals. One study showed no correlation to a increase
in stomach in cancer in humans. In California, it's
classed as a carcinogen and similarly in Europe, you
can't put it in food (a study . In Canada, though,
food manufacturers can use it as a preservative.
Sodium benzoate is common in jams, pickles, sauces and
drinks, and it's generally thought to be safe in low
doses. But the FDA found in 2005 that it can combine
with vitamin C to form benzene (a carcinogen). (Here's
