Many
of us are concerned about the adverse health effects of environmental
pollutants such as agricultural pesticides and industrial chemicals. In
recent years, there have been bans on certain chemicals, as well as
ongoing research into the effects of others. The federal government took
a major step when they implemented national standards for organic
produce in October 2002.
While the
specific health effects of most pesticides and environmental toxins have
not yet been established, the research to date indicates that low dose
exposure to industrial chemicals and pesticides does present a
significant risk to human health.
Endocrine and
nervous system disorders, as well as many cancers, are just some of the
health problems that have been linked to long term, low dose chemical
exposure.
The idea that
organic produce is healthier than produce grown with agricultural
chemicals has mostly been based on the absence of environmental toxins
rather than a higher nutritional profile. But could organic produce also
have additional health benefits that produce grown with pesticides is
missing? According to UC Berkeley, a recent study found organic fruits
and vegetables to have more phytochemicals than conventionally grown
produce (produce grown using pesticides.) Phytochemicals are naturally
occurring plant chemicals that have numerous health benefits. One theory
behind this interesting discovery is that phytochemicals act as the
plant’s natural pesticides. When synthetic pesticides are used, the
plant has less need to produce its own defenses and thus produces less
phytochemicals.
In a perfect
world we would eat only organically grown foods with their abundance of
healthy phytochemicals and absence of toxic residues. Unfortunately, it
may not always be possible to choose organic produce. The Environmental
Working Group, a non-profit environmental research organization, has
developed the “Shopper’s Guide to Pesticides in Produce.” This is a
handy guide to which produce items are highest and lowest in pesticides,
so that if you are unable to buy organic, you can at least make informed
decisions about the conventionally grown produce that you consume. For

In addition to
awareness of chemicals in your produce, there are many other simple
steps you can take to avoid exposure to
environmental toxins:
Reduce your
consumption of processed foods. Processed foods usually contain
additives and preservatives as well as being lower in nutrients than
their whole food counterparts.
Reduce your
consumption of meats and high fat dairy products. Because toxins
accumulate as you go up the food chain, replacing meat and animal
products with whole grains, beans, soy products, fruits and vegetables
will also reduce your exposure to environmental toxins. This is not to
say that you need to follow a vegetarian diet, but consider reducing
your overall intake of animal products.
Microwave your
food in glass or ceramic containers rather than plastic to avoid
leeching of chemicals into the food.
Reduce the
number of household cleaning products that you use. Look for the
biodegradable alternatives widely available in health food stores. Use
non-toxic cleaning products, such as baking soda, that are already in
your home. Many companies that sell environmentally-friendly cleaning
products have great cleaning tips on their websites.
Reduce the
number of personal care products and cosmetics that you use. These
products may contain harmful chemicals. You can also look for products
that contain non-toxic alternatives. However, be aware that the term
“organic” is not regulated on non-food items and “natural” doesn’t
always indicate a better product. Read the labels and see how many
ingredients you recognize. |
