There are some key aspects of foods' nutrition and
healthfulness to consider when choosing healing
foods – we want ones that are high in supportive
nutrients and that are clear of toxic chemicals.
Consuming foods as they are grown from Nature is
where to begin – fresh fruits, wholesome vegetables,
hearty whole grains, lively legumes, nutritious nuts
and seeds, some calming low-fat dairy, and non-toxic
animal proteins, from eggs to flesh if these are
desired and feel right for you. Then, make sure the
main foods you eat are not filled with additives or
exposed to pesticides and other chemical sprays, or
contaminated in other ways, such as from the water,
soil, or industrial treatments.
The key foods to buy organically grown and/or
manufactured from organic ingredients are:
- Those that are commonly heavily treated, such
as strawberries and animals;
- Those where you consume the parts that are
sprayed, as in leafy greens or broccoli;
- Those that you consume frequently, whereby
you'll get higher accumulated exposure over time,
as in apples or bananas.
Ideally, our entire diet could be made up of
wholesome, healthy organic and clean foods.
My list for Ten Healing Foods To Buy Organically
Grown includes:
Strawberries
Strawberries are red and energizing, rich in vitamin
C and carotenoids (beta-carotene and others). But
this fruit is the most heavily contaminated produce
food in the U.S., according to data from a number of
environmental groups, including a 1993 study by the
Environmental Working Group (EWG of Washington, DC)
and an analysis by the Pesticide Action Network of
North America (PANNA). Strawberries in California
are treated with more than 300 pounds of pesticides
an acre, and some areas of the country use up to 500
pounds per acre. As a comparison, conventional
farming currently uses about 25 pounds of pesticides
an acre on the average crop. Also, some growers may
be spraying the harvested strawberries for shipping.
This adds to the amount of chemical concentration in
the fruit. Strawberries were also found to have the
highest level of hormone-affecting pesticides,
including benomyl, vinclozolin, and endosulfan.
Methyl bromide is another common toxic spray used on
strawberries. Note that out-of-season strawberries
may be even more heavily treated because they come
from other countries and are sprayed before
shipping.
Leafy Greens, such as Lettuces, Spinach, Kale,
and Chard
These foods are considered vital and nutritious.
They contain folic acid as well as calcium, iron and
other minerals. However, sprayed chemicals tend to
remain on the leaves of these vegetables, which is
potentially more harmful since we eat those leafy
parts. In FDA studies, spinach was the most
frequently found leafy green to contain the more
potent pesticides, especially the organophosphates
(neurotoxins) and permethrin (noted as mildly
carcinogenic).
Grapes
All grapes contain cleansing fibers, B-vitamins and
vitamin C, plus some minerals from the soil. Red
grapes contain many phytonutrients, including the
healthy proanthocyanadins, which appear heart
protective. Unless they are organically grown,
however, grapes may receive multiple applications of
a variety of chemical agents during their growing
period. Many fruits, including grapes, ripen quickly
and attract insects and molds. Thus, they tend to be
more heavily treated in order to get them to the
market (and to protect the financial interest of the
grower). FDA research indicates that imported grapes
are even more heavily treated than the U.S. samples.
During winter and early spring, almost all grapes
available in the U.S. are from Chile, and these are
found to have an exceptionally high percentage of
pesticide residues (79%). They also have a higher
percent of the carcinogenic pesticides, captan and
iprodione. However, U.S. grape growers use high
amounts of sulfites and the fumigant, methyl
bromide, so these are all good reasons to buy
organic grapes and grape juices.
Rice
This is the most frequently consumed food on the
planet. And this high-fiber, low-fat staple has many
B-vitamins and minerals, including the important
anti-oxidant, anti-cancer mineral, selenium. You
should seriously consider buying organically grown
rice and rice products, especially if it is one of
your staple foods. The dangerous herbicide 2,4,5-T
was sprayed on rice before being banned in 1984, and
many persistent water-soluble herbicides and
insecticides have been found to contaminate the
ground water near major rice fields, such as in
California's Sacramento River Valley. I suggest
buying organic rice in bulk. You'll find that this
way it's as economical as non-organic pre-packaged
rice and much safer.
Cruciferous Vegetables (Broccoli, Cabbage,
Brussels Sprouts, and Cauliflower)
Because of their healthy anti-cancer phytonutrients,
vitamin and mineral content, high-fiber and
low-calories, these are excellent foods to eat
regularly. But since we eat the parts that may have
been sprayed with carcinogenic chemicals, it's best
to eat the organically grown versions of these
vegetables.
Apples
A staple in many diets, they contain cleansing fiber,
detoxifying pectin, and many nutrients. However,
most apples have been found to be nearly as
contaminated as strawberries. Forty eight different
pesticides were detected by FDA testing in nearly
2500 samples from 1984 to 1991, while 36 different
chemicals were found in their 1992 to 1993
evaluations. Nearly half of these 36 were either
neurotoxic or carcinogenic chemicals. In the FDA
analyses, apples and peaches were the two crops with
the greatest number of different pesticides per
crop--seven! Fortunately, a shift away from spraying
the orchards is occurring in some areas; about 70%
of the apple growers are using organic practices and
integrated pest management. If you buy non-organic
apples, be sure to peel them and discard the skin
before you eat them since most of the chemical
residues are on the apple skins. We might want to
change our saying to "an organic apple a day keeps
the doctor away."
Almonds and Sunflowers Seeds
These nutrient-rich life forms of Nature contain
most vitamins and minerals as well as the vital
essential fatty acids (EFAs). They also can hold
more pesticides and other chemicals in their oils,
since many are attracted to oil more than water.
They are compact essences of nutrition with many
B-vitamins, minerals (even hard-to-find minerals
like zinc and selenium), and healthy, tissue-feeding
essential oils. It is wise for humans to consume the
freshest low-salt samples of these "mini-vitamins."
Add to this list some pumpkin seeds, walnuts, pine
nuts, and sesame seeds.
Tomatoes & Sweet Peppers (even though I wanted to
say "Sweet Potatoes", more poetic)
These "fruits of the vine" are full of healthy
nutrients that include vitamin C, B-vitamins,
carotenoids, and other phytonutrients, especially
the prostate-helpful and tissue-supporting lycopenes.
Both red and green bell peppers were found to have
many pesticide residues from the most neurotoxic of
the pesticides. In the FDA's measurement of both
U.S. and Mexican crops, 64% of peppers contained at
least one pesticide, while 36% contained two or
more. These vegetables also may be waxed which makes
it difficult to remove the residues and other
chemicals within the waxes. One study found that as
many as 30 different pesticides are used to spray
tomatoes. Because the skins of tomatoes are thin and
absorbent, and since this is a staple in many
salads, soups and sauces, tomatoes are worth buying
organically grown. At certain times of year, the
price of organic plum tomatoes is competitive with
non-organic varieties. And farmer's markets may be
the best source of all for fresh unsprayed tomatoes,
or better yet, grow your own.
A couple other classes of fruits and vegetables that
are healthy for us are also best looked for and
consumed from organic growing and shipping practices
include:
Tropical Fruits
Although wonderfully tasty and high in carotenes and
continuing many other nutrients and enzymes,
pineapples, papayas and mangoes are very attractive
to tropical pests and may be more heavily treated
during cultivation, storage, and shipping. Because
of their thin skins, they tend to absorb the sprays,
creating higher levels of chemical contamination. We
call these systemic pesticides, and they cannot be
washed away such that they get into our systems as
well.
Imported Produce
This usually out-of-season produce is often heavily
treated for easier growing and shipping to the
United States. There is also risk of higher toxicity
from the use of chemicals that have been banned in
the U.S. Cantaloupes and other imported melons were
found to have a high concentration of pesticides in
two thirds of tested samples. In Mexican
cantaloupes, 48% had two or more residues.
Baby Foods
Whenever we are feeding an infant, we want to make
sure we do not stress their sensitive and vulnerable
systems with chemicals. I suggest a completely
organic diet from the first feedings at about six
months through age two.
Shop Locally
Ideally, it is healthiest to eat foods grown and
cultivated near our area and in the season they are
harvested. Seasonal eating is one of the keys to a
balanced and wholesome diet. These foods are the
freshest, often the most economical, and usually
less treated, even non-organic, because they don't
need to be protected for shipping long distances.
Eating as much as possible from Nature, the bounty
of Mother Earth, is a key message for healthy
nutrition.
Other Healing Foods that may or may not be available
organically grown include: oily (omega-3 oils) fish
like Salmon, Olives and Olive Oil, Wild Berries or
Blueberries, and Garlic and Ginger.
Important note about Milk Products and Eggs; also
Wheat and Corn
Because pesticides are pervasive and stored in
higher amounts in the fats of food, dairy products
tend to retain higher levels of residues and
chemicals from feeds and other sources. This is not
well researched yet; however, it makes total sense
to me, and therefore my family with growing children
is buying organic milk products.
- Milk is a common source of the herbicide
atrazine (a known endocrine-disrupter) and the
growth hormone BGH which has been genetically
engineered to boost milk production.
- Eggs are one of the more bio-available
proteins especially for growing folks, pregnant
women, and those needing a protein source,
especially if you digest them well and aren't
allergic to them. They have many nutrients that
feed the body tissues, the sexual glands, sperm
and eggs, and hormones. However, eggs are
typically produced in factory farms where the hens
often live in crowded, unhygienic conditions. This
may be one of the reasons that salmonella bacteria
are found in eggs so frequently. More than two
million eggs each year are contaminated, resulting
in more than a half million cases of food
poisoning. Factory farm eggs also may be lower in
nutrients than organic ones, and they don't taste
as good as farm fresh eggs from the free-ranging
chickens that are not fed antibiotics. Our best
egg option is organic eggs, which are now becoming
more available.
- Wheat is another staple in the American and
world diet. It has many vitamins, minerals, and
fiber. However, in a recent review of pesticide
residues, 91 percent of the wheat sampled by the
FDA contained pesticide residues! Wheat can be one
of the most heavily treated grains, because it is
stockpiled as a basic commodity and fumigated
periodically to keep down pests. When it is
milled, the outer coating--the bran included in
whole wheat bread and cereals--is the portion that
receives the most chemical treatment. The bran and
germ portion of the wheat also retains the most
residues. It has been suggested that some forms of
so-called wheat allergy, which has been associated
with learning problems and difficulty in
concentrating, may actually be a neurotoxic
reaction to the pesticide residues in the grain.
These pesticides are by definition neurotoxins
that is how they affect the insects they are
intended to destroy.
- Corn contains most B vitamins, especially
niacin, and adds helpful fiber to the diet. A
primary staple in the American diet, corn is
typically heavily treated. Locally grown fresh
corn tends to be treated less, so sweet corn on
the cob is likely safer than corn byproducts,
which may have more contamination. However, corn
is still heavily treated with the herbicide
atrazine and it is also typically sprayed after
harvesting.
Overall, it's important to eat healthy to Stay
Healthy! and Enjoy what you do choose to consume.
