Fats:
Safer Choices for Your Frying Pan and Your Health-Part 2
by Caroline Barringer, NTP, CHFS, FES
So, which fats
and
oils should you choose for cooking?
Below is a color-coded guide to help you determine which fats and oils
are safest to include in your favorites recipes.
(Green
=
Safest
for cooking;
Yellow
= Safer for Cooking;
Red
= UNSAFE for
Cooking)
SAFEST FOR COOKING
(frying,
baking, broiling, grilling and roasting)
• Lard
• Ghee
• Beef and Lamb Tallow
• Chicken, Duck, and Goose Fat
• Coconut Oil – organic and virgin
• Red Palm Oil – organic and virgin Palm kernel oil is also
acceptable)
Tropical vegetable
fats in this category should be organic and unrefined in nature.
The animal fats should be from organically raised, grass-fed pastured
animals.
Lard:
Lard is the fat
from
pigs (pork fat). It is safe for cooking and frying due to its nearly
equal fatty acid profile of 40% saturated and 48% monounsaturated
fats.
Lard has only 12% PUFA’s (poly-unsaturated fatty acid) and will vary
depending on the animal’s diet. Lard is a healthful source of vitamin
D.
Ghee (Indian
Clarified
Butter):
Ghee is a stable,
saturated butterfat with the milk solids (casein proteins) removed.
It
is safe for cooking and light frying. If you are intolerant to
butter,
try ghee. Ghee is prepared by melting and simmering unsalted butter
at
a medium temperature until the water content of the butter has
evaporated off. This allows the casein to separate and sink away from
the butter fat. Next, the butter fat is carefully removed leaving the
milk proteins behind. The butter fat is then allowed to cool and
solidify to be packaged as ghee. Be sure the ghee you purchase is
made
from organic, grass-fed butter. There are several brands of ghee
available at health markets, but if you wish to prepare your own
homemade ghee, please view this helpful instructional video:

Beef and Lamb
Tallow:
Very safe for cooking and frying. Tallow fats are 50-55% saturated,
40%
monounsaturated and only 3% or less polyunsaturated. McDonald’s first
fried their French fries in 93% beef tallow (along with 7% cottonseed
oil) before changing over to vegetable oils with added chemical flavor
enhancers in 1990.
Chicken, Duck and
Goose Fat:
These bird fats are quite stable. They are highly regarded as
healthful
fats in Europe and beyond. Duck and goose fats are somewhat superior
to
chicken fat due to their higher saturated fatty acid content and are
safer for sautéing and frying at higher temperatures. Chicken fat has
a
higher MUFA (mono-unsaturated fatty acid) profile and a lower
saturated
fatty acid profile, so chicken fat is best used for low to medium heat
cooking (quick stir-frying, light sautéing, and slow, low
simmering).
Coconut Oil:
This
healthful
tropical oil is almost fully saturated (92%). It has powerful
antimicrobial and antifungal properties and contains a medium-chain
fatty acid called lauric acid, which is found in abundant quantities
in
breast milk. I like to combine coconut oil with ghee or lard when I
don’t want to taste coconut in my recipes. Coconut oil is safe for
cooking and frying at higher temperatures. My favorite brand of
coconut
oil is Nutiva. I often use it in place of butter on toast and toasted
mochi.
Red Palm Oil:
This deep orange-red tropical oil has a pungent, paprika-like flavor
that is, in my opinion, best suited for roasting root vegetables. Try
roasting red and white potatoes, red, yellow, and orange bell peppers,
fresh garlic and herbs in red palm oil. Butternut squash and parsnips
are also delicious when roasted in red palm oil. It is a nice change
from the usual oils used for cooking and brings color to your plate.
SAFER
FOR COOKING
(quick stir-frying, light sautéing, and slow/low simmering)
• Olive Oil
(Unfiltered is best; should be golden yellow/green in color and
cloudy.)
• Peanut Oil
• Avocado Oil
• Macadamia Nut Oil
• Sesame Oil
These oils should
ALWAYS be extracted via expeller-pressing! Read the label first!
The Olive Oil
(oleic
acid) Myth:
Olive oil contains 75% MUFA’s. It is relatively stable for cooking.
There has been a rumor moving its way through the holistic community
for
the past several years stating that trans fats are formed when olive
oil
is exposed to higher temperatures. Fat expert Mary Enig does a
beautiful job of explaining that this rumor is not only untrue,
but completely lacking in supportive scientific evidence. Lightly
cooking with olive oil over a medium heat (less then 400 degrees) is
considered safe.
Can olive oil and its MUFA molecules be damaged at high heats
resulting
in free radical production? Yes, but these unstable molecules are
different from trans fats, so please do not confuse the two. Again,
to
form a true trans fat, the fat must be exposed to extreme
pressure and temperatures, metal catalysts, chemical solvents, etc, in
a
closed container to actually alter the chemical structure of a fatty
acid molecule from its natural “cis” formation to a “trans”
formation.
Peanut Oil:
Peanut oil
is
relatively stable due to its MUFA content. Use it occasionally for a
quick stir-fry, but the key word here is “occasional”. Peanut oil
also
has a significant PUFA content, so limited use is recommended.
Avocado Oil:
A relatively new edible oil to the market since 1999, avocado
oil
has been previously used for many years as a moisturizing agent in
cosmetic and hygiene products. Avocado oil is not extracted
from
the pit, rather it is extracted from the fatty pulp, which is high in
MUFA’s. It is similar to olive oil, so the same cooking rules
apply.
Macadamia Nut Oil:
Macadamia nut oil contains nearly 80% MUFA’s. It is very close to the
fatty acid profile of olive oil, so the same cooking rules apply. Mac
oil has a distinctive, nutty flavor and is delicious in salad
dressings. Look for expeller-pressed, organic UNBLENDED versions of
this oil. Stores in the refrigerator for up to one year.
Sesame Oil:
Like peanut oil, sesame oil is relatively stable. Sesame oil falls
right between a MUFA and a PUFA (42% MUFA, 43% PUFA), but it has high
levels of antioxidants for protection against oxidation, so sesame oil
may be used for low-heat stir-frying or a quick sauté on a very
limited
basis. Combining sesame oil with olive oil and/or other stable
saturated animal fats will help protect sesame oil when cooking.
UNSAFE FOR ANY
KIND OF HEAT EXPOSURE! DO NOT USE FOR COOKING!
•
Vegetable/Soybean
Oil
• Corn Oil
• Flax Oil
• Hemp Oil
• Pine nut Oil
• Pumpkin Oil (safely roasted or raw versions)
• Safflower Oil (80% omega-6!)
• Sunflower Oil
• Grapeseed Oil
These PUFA oils are
comprised of nearly half omega-6 fatty acids and should NEVER be used
for cooking! If you do wish to consume these oils, do so in
moderation,
buy them from healthy sources and be sure that they are never refined
or
processed; although finding truly unprocessed versions of these oils
is
a difficult task! Corn and soybean oils are best avoided due to their
genetically modified status and heavy pesticide levels.
Use omega-3 rich
oils,
like flax (and even smaller amounts of omega-6 oils) sparingly in
salad
dressings (add flax in small amounts to a base of olive oil); in small
servings in a condiment such as homemade mayonnaise; stir them in
small
amounts into freshly prepared smoothies, lightly drizzle them over
cold
soups, dips, and hors d’oeuvres, or consume them right off the spoon
in
very limited quantities as a dietary supplement.
Grapeseed oil:
There are
many
conflicting opinions about the safety of cooking with grapeseed oil.
Like sesame oil, it has a higher smoke point due to its antioxidant
content. Regardless, grapeseed oil is very high in PUFA’s and should
not be used for cooking.
A note about liquid Evening Primrose, Borage, and Black Currant Oils:
These omega-6 fatty acids, whether liquid or contained is a soft-gel
supplement, are widely available in health markets. They are
nutritionally supportive to the endocrine system and are mass marketed
to women especially to help balance hormones. PLEASE DO NOT COOK WITH
LIQUID BORAGE, EVENING PRIMROSE, OR BLACK CURRANT SEED OILS! They are
highly reactive and should never be heated. If you do wish to
supplement with these oils, consume them in very small amounts as you
would any other omega-6 PUFA.
The following oils
are
UNSAFE to consume under any circumstances!
CON-ola (Canola
Oil):
Even though Canola is classified as a monounsaturated fat, it is also
naturally high in omega-3 fatty acids. Extracted from the hybridized
rapeseed, which is a genetically modified crop, canola is a HIGHLY
PROCESSED oil! The omega-3 fatty acids in canola are delicate and
turn
rancid quickly during processing. Therefore, given the fact that
canola
oil must move through damaging extraction processes to be harvested
and
deodorized, it is safe to say that canola oil is unfit for
consuming,
much less cooking! It is an oil of industry and DOES NOT belong in
the
human digestive tract! Canola is the current oil of choice for
prepared
foods at Whole Foods Markets across the country.
Cottonseed Oil:
Cotton is one of the most genetically modified, pesticide-laden crops
in
America. Besides the danger of ingesting these pesticides, when did
cotton and its seed become a food? Is there anyone out there eating
cotton for breakfast? I certainly hope not! Mentioned earlier in
this
article, the extraction and hydrogenation processes quarantine
pesticides in the oil, therefore the high pesticide levels found in
cotton are reason enough to recommend it as inedible! Cottonseed oil
is
hydrogenated most of the time and is one of the main ingredients in
Crisco shortening along with hydrogenated soybean oil. Avoid
cottonseed
oil at all costs!
Don’t forget about
the
health benefits of good, old-fashioned REAL BUTTER!
Butter is a dirty word among today’s general population, but the
TRUTH is our ancestors prized butter for its life-giving
nutrients!
Raw, unprocessed butter fat from grass-fed cows has a comprehensive
fatty acid profile that protects it consumer from developing
*imbalances
such as hardening of the arteries, calcification of organs, glands and
joints (arthritis), and cataracts. Most of us receive enough calcium
from our regular diets, yet our bodies lose the ability to properly
utilize this calcium intake. As a result, we appear to have a calcium
deficiency in an actual state of calcium excess
due to a lack of the necessary cofactors (healthy fats and fat
soluble vitamins) found in foods like raw butter, to aid our bodies in
using calcium and other minerals in an effective manner. The excess
calcium must be stored somewhere, so the innate intelligence of
the body begins to store it in unusual places (arteries, kidneys,
gallbladder, eyes, joints, etc.), resulting in the aforementioned
imbalances*.
Quality raw butter
contains: Omega-3 and omega-6 fatty acids in small amounts in a
healthful ratio; CLA or Conjugated Linoleic fatty aids for
better
weight management, muscle growth, and protection from cancer; Fat
soluble vitamins A, D, E, and K to help us absorb and properly
assimilate naturally occurring trace minerals (zinc, selenium, iodine,
chromium, manganese, etc,) found in raw butter; Butyric fatty
acids for protection against fungal infections and tumor growth; and
Arachidonic fatty acids for proper inflammatory and
anti-inflammatory responses to heal effectively. Butterfat enhances
brain function and increases cell membrane integrity. With all these
health benefits, raw organic butter should be a central dietary fat
consumed each and every day.
A word to the wise
about fats!
Choose your fats
wisely and with GREAT CARE to ensure they have been minimally and
safely
processed, or better yet, not processed at all; and remember… healthy
fats are not the enemy and healthy fats do not
make you fat! Consume a wide variety of fats from whole oils to whole
foods containing healthy fats and carefully monitor and limit your
consumption of PUFA’s. If you want to learn more about fats and the
