Omega Fatty Acids Provide Relief for Allergic Pets |
|
| |
For several years, omega fatty acids have been in the
natural medicine limelight for reducing excessive
inflammation associated with allergies and arthritis.
Dr. Karen Campbell, veterinary dermatologist at the
University of Illinois Veterinary Teaching Hospital in
Urbana, notes that there are different types of omega
fatty acids, specifically omega-6 and omega-3 fatty
acids, and distinctions between these must be understood
when considering fatty acid supplementation.
Omega-6 fatty acids are "essential" nutrients for most
mammals, meaning that they are required for basic
biochemical functions. Since the body cannot produce
them, they must be acquired through the diet. They are
commonly found in vegetable oils such as sunflower,
safflower, soybean, and corn oil--oils that, as Dr.
Campbell explains, come from terrestrial sources. These
fats are directly involved in maintenance of normal,
healthy skin.
A specific omega-6 known as linoleic acid acts as a
mortar between skin cells, maintaining skin strength and
preventing moisture from evaporating. Linoleic acid, a
common ingredient in premium pet foods, helps promote a
shiny, healthy coat and prevents dry, scaly skin.
Unfortunately, omega-6 fatty acid can also exacerbate
inflammatory allergic reactions. Omega-6 fatty acids are
transformed by the body to produce eicosanoids,
biochemicals that contribute to inflammation. In animals
with allergies, omega-6 fatty acids can actually fuel
inflammation by providing the building blocks for
excessive amounts of eicosanoids.
Fortunately, another family of omega fatty acids,
omega-3 fatty acids, can help balance the body's
inflammatory response. Since eicosanoids produced from
omega-3 fatty acids are much less inflammatory, keeping
this class of fatty acids available in the bloodstream
can actually reduce inflammation.
"The metabolic process prefers omega-3 fatty acids, so
the body will use them first to produce the less
inflammatory eicosanoids," says Dr. Campbell, explaining
why omega-3s work.
Omega-3 fatty acids are found in fish and flaxseed oils.
Since these foods are less common in diets than soy or
corn, most animals (including humans) typically consume
lower amounts of omega-3 fatty acids. Supplementation
can help provide these oils, which may also be essential
for brain development in infants and other young
animals.
According to Dr. Campbell, both omega-6 and omega-3
fatty acids are important for allergic pets. "Omega-6
fatty acids keep the skin hydrated and help create a
protective barrier against absorbing allergens, while
omega-3 fatty acids can minimize inflammation caused by
allergens." However, she sometimes prescribes only
omega-3 fatty acids to itchy pets if they already get
plenty of omega-6 fatty acids in their diet.
Dr. Campbell also explains that omega-3 fatty acids can
help reduce inflammation in many conditions besides
allergies, including arthritis and kidney disease.
Several types of omega-3 fatty acid supplements are
available from your veterinarian or local health food
store in liquid or capsule form. Many veterinary
preparations also contain vitamins B and E, which help
certain species utilize fatty acids better.
