EFAs are Perishable

"EFAs are perishable, deteriorating rapidly when exposed to

·        light,

·        air,

·        heat and

·        metals.

Unlike vitamins, EFAs cannot be dried, powdered, and stored for several years. EFA sensitivity makes careful processing and freshness extremely important."

The Edelson Center: Essential Fatty Acids: The Healing Fats

 

"In nature’s package, EFA-rich oils keep for years without spoiling. Out of that package, light, air, and heat attack EFAs. Like perishable produce, EFA-rich oils should be made with care and obtained fresh [and sometimes refrigerated]."

The Edelson Center: Essential Fatty Acids: The Healing Fats

 

Frying and Deep Frying

"Frying and deep frying destroy EFAs by the combined effects of light, oxygen, and heat, producing toxic substances that produce atherosclerosis [a common arterial disease] and cancer."

The Edelson Center: Essential Fatty Acids: The Healing Fats

 

Packaging

"EFA-rich oils should be made and packaged in the absence of light, oxygen, and heat. Frozen solid (which does not damage them), oils remain unspoiled for a long time. Manufacturers should ship them directly to retailers or consumers without stops along the way."

The Edelson Center: Essential Fatty Acids: The Healing Fats

 

Foods Containing Omega-6 EFAs

"…Omega 6 EFA, which is called linoleic acid (LA). LA is abundant in polyunsaturated safflower, sunflower, and corn oils."

The Edelson Center: Essential Fatty Acids: The Healing Fats

 

"Omega-6…is found in seed oils, sunflower, corn and sesame oils."

ILT: Essential Fatty Acids (EFAs)

 

Foods Containing Omega-3 EFAs

Some Sources

"Omega-3…is found in cold water fish, such as salmon, tuna and trout, as well as dark leafy vegetables [purslane], and vegetable oils, such as flaxseed oil."

“I remember FDA agents finding cat hairs and rat feces in the *chunk* tuna and an alert going out that those items would not be found in 'white albacore' [albacore tuna contains more mercury] tuna because it was- so to speak- about as clean as if it were 'Kosher'.

     Me and my wife *only* buy white albacore tuna, not only for health reasons but because it makes a better sandwich and seems to be tastier instead of 'tuna fishy' tuna (as she says).
     The 'crappy tuna' (yes it does have a name and designation in this household) is great for regular, 'quickie' tuna sandwiches. But the stuff like Geisha- which tends to be a more expensive brand- or even 'Chicken of the Sea White Albacore'- makes a better, more healthier sandwich, IMHO.”

“Certainly, many fish pose no known health risks to any consumers. These include

·        flounder,

·        farmed rainbow trout,

·        sole,

·        anchovies, and

·        farmed clams and shrimp.

Other fish are fine to eat in moderation—approximately once a week—such as

·        cod,

·        farmed catfish,

·        mahi mahi,

·        wild salmon,

·        tilapia, and

·        canned chunk tuna.”

Annals of Internal Medicine--Volume 141 (#12, December 2004): Page 977: 'Balancing the Risks and Benefits of Fish Consumption'

 

“Methylmercury [mercury is a neurotoxin; pregnant women and young children are especially susceptible to its effects.] reaches its highest levels in large, predatory fish and in bottom feeders (i.e. crab).  Fish highest in mercury in terms of mean values of methylmercury concentration in ppm are

·        tilefish (1.45),

·        swordfish (1.00),

·        king mackerel (1.00),

·        shark (0.96),

·        fresh or albacore tuna (0.32),

·        light tuna (0.12),

·        pollack (0.20),

·        canned tuna (0.17)

“Light tuna has less mercury than albacore which comes from larger fish. Chunk-light contains even less than solid-light. Consumer’s Union [Consumer Reports magazine] recommends adults limit intake to no more than 3 cans [3 cans at most] of chunk-light or 1 can of solid-light or white albacore per week.”

You should know: You can go to GotMercury.org and enter the type and amount of fish you will be eating plus your weight, and the site will calculate how much mercury you will eat. This is an excellent resource to use.”

Free Range Meats, Eggs

"Today, much of our farmed meat supply (chicken, beef and pork) is fed on large amounts of corn and soybean meal that contain Omega-6 EFAs but little or no Omega-3 EFAs. This is the reason for the recent interest in free-range meats, and eggs from free-range chickens."

Walnuts

"FDA says eating walnuts may help reduce risk of heart disease. The FDA's decision said that eating 1.5 ounces [43 grams, 3 tablespoons] of walnuts a day helps boost cardiovascular health. Eating that quantity also would fulfill the daily requirements of essential omega-3 fatty acids, which also reduce the risk of heart disease."
