Does baking with walnuts or ground flax seed destroy the Omega 3?

[Guest guest]

After reading the excerpt I included from the article below, I'm wondering

if baking with walnuts or ground flax seed ( like putting them in cookies or

zucchini bread) destroys the Omega 3 fatty acids?

Also, would it be better to store fish oil pills in the refrigerator or the

freezer? Or is room temperature OK? The jar it came in does not mention

refrigeration.

A bag of walnuts says 2.5 g omega 3 per 1 oz serving (which is 1/4 c)

A jar of fish oil pills says 2 pills contains 432 mg Omega 3 (EPA) & 288 mg

Omega (DHA) which added together is 720 mg which equals .7 g

So am I correct in assuming that I get as much Omega 3 in 1/4 cup walnuts as

in 7 fish oil pills?

Thanks in advance for any information you can offer.

How do cooking, storage, or processing affect omega 3 fatty acids?

Polyunsaturated oils, including the omega 3 fats, are extremely susceptible

to damage from heat, light, and oxygen. When exposed to these elements for too

long, the fatty acids in the oil become oxidized, a scientific term that

simply means that the oil becomes rancid.

Rancidity not only alters the flavor and smell of the oil, but it also

diminishes the nutritional value. More importantly, the oxidation of fatty acids

produces free radicals, which are believed to play a role in the development of

cancer and other degenerative diseases.

Under most circumstances, the problem of rancidity only arises when the oils

are removed from their natural food package. For example, the hard shell of

the flaxseed protects the oil inside the seed from heat, light, and oxygen.

Flaxseeds also contain antioxidant compounds, such as _vitamin E_

(http://www.whfoods.com/genpage.php?tname=nutrient & dbid=111) , that provide

additional

protection against oxidation. But, when the seed is pressed to isolate the oil,

the oil becomes vulnerable to the elements.

As a result, oils rich in polyunsaturated fatty acids should be stored in

dark glass, tightly closed containers in the refrigerator or freezer. In

addition, these oils should never be heated on the stove. So, instead of

sautéing

your vegetables in flaxseed or walnut oil, make a salad dressing using these

oils.

Form in Dietary Supplements

What forms of omega 3 fatty acids are found in dietary supplements?

When purchasing an omega 3 fatty acid supplement, remember that these oils

are highly sensitive to damage from heat, light and oxygen. Choose a certified

organic product that has been refrigerated and is packaged in a dark brown

or green glass jar and be sure to store the product in your refrigerator or

freezer.

What foods provide omega 3 fatty acids?

Salmon, flax seeds and walnuts are excellent sources of omega 3 fatty acids.

Very good sources of these healthy fats include scallops, cauliflower,

cabbage, cloves and mustard seeds. Good sources of these fats include halibut,

shrimp, cod, tuna, soybeans, tofu, kale, collard greens, and Brussels sprouts.

A good rule of thumb is whenever you heat something you destroy the good in it,

milk, eggs, plants, especially oils! They go rancid fast enough just sitting on

a shelf. Even refrigerated oils lose their potency. In other words, yes.

Simple answer - yes, to a degree...
