Purchase: First, don’t skimp here. Buy from a reputable manufacturer, such as Barleans or Flora, both of whom have taken deliberate steps in the preparation and delivery process. Cheaper pressure extraction processes are done in oxygen rich environments and generate heat in the method. Both contribute to degrade the product. These two companies endeavor to use mechanical extraction methods that minimize heat, oxygen and exposure to light. They package the oil immediately and ship cold with a date of preparation and date of expiration.
Maintenance: Keep bottles that are being stored, open or unopened in the freezer. (They won’t break) Keep small amounts that are going to be used within a 2-3 weeks in the refrigerator.
Preparation: Here is where most people go wrong. Absolutely, positively, do not fry with this oil. Do any hot cooking with an oil that does not readily degrade under heat. The oil of choice is extra virgin olive oil. This is a largely mono-saturated oil that maintains it’s integrity over higher heats. Even then, practice steam frying, whereas water is added to the pan to keep temperatures down.
Flax oil is best used in salad dressings and the like where it can be prepared without heat. 1-3 teaspoons are all that are really needed daily to provide plenty of omega-3’s for health. It can also be used in baked goods as the internal temperatures of baked items, such as breads, do not get too high above steam temperatures. Boiling is acceptable, as the temperature is at or below 100oC. Some suggestions as to the use of this oil in cooking are provided below.
In all, flax is a quality oil that has a very impressive track record of benefits. It is worth noting, however, that the two essential fats are instrumental in to the production of cell membranes and other cell structures and organelles, prostaglandins (good and bad), hemoglobin, along with increased metabolism and heat generation. The production of the prostaglandins, particularly the most beneficial series 1 and series 3 which are responsible for controlling pain and inflammation, blood viscosity, production of steroid structures, requires conversion through some particular desaturase enzymes. These enzymes naturally decline with age and body stress. As such, the essential fats may not end up where you want them. As a hedge to this, many people consume the converted form of these fatty acids, fatty acids called EPA and DHA, the widely recognized beneficial oils found in fresh cold water fish. Yep, I mean fish oil such as cod liver oil, although capsules are available albeit considerably more expensive. These oils should be purchased and treated in the same fashion as flax oil. Eating 2-3 servings of cold water northern fish can help, but problems arise in getting quality product in a landlocked state. I recommend a high quality oil that has been screened for heavy metals, a growing problem in fish.
Flax Uses:
Don’t forget flax seeds! Buy them fresh and grind them using a small coffee mill or spice grinder. (Inexpensive item..useful! I buy whole spices in bulk as they are very inexpensive, keep well, and are incredibly good when freshly ground. Examples include coriander, cumin seed, cloves, etc.) The resulting meal can be sprinkled over cereal, mixed in oatmeal, top breads, mixed with honey to make a spread, mixed in steamed veggies to give them a nutty flavor, etc. Seeds keep very well in the fridge as they contain and protect the oil. The seeds themselves make a great addition to nut toppings or other nut/seed uses. Example: mix a small amount of sunflower seeds, flax seeds, sesame seeds and rolled oats with a touch of honey or apple juice and mix into plain non-fat yogurt.
