EFA’s, what are they? Why are they important?
EFA’s stand for essential fatty acids. They are termed “essential” because the body cannot create them and therefore consumption in the diet is essential.
A diet or supplement rich in EFA’s is used to treat depression, dementia, anxiety, rheumatoid arthritis, heart disease and high blood pressure, eczema, PMS, fertility, asthma and the list goes on!
Omega-6 fatty acids (linoleic)
- Used in the treatment of PMS, hormonal imbalance, psoriasis, eczema and asthma
- For maintanence of healthy blood pressure and a healthy heart
- Omega-6’s are abundant in the Canadian diet
Dietary Sources of Omega-6 Fatty Acids:
Omega-6’s are found in nuts, seeds, legumes, cereals, eggs, poultry, avocado, vegetable oils, whole-grain breads, baked goods and corn, canola, safflower, soybean and sunflower oils.
Supplemental sources of Omega-6 Fatty Acids
- Flaxseed oil, evening primrose oil, borage oil, hemp oil
- These oils in liquid form should always be refrigerated
- Never heat or use in cooking
- Flax and hemp come in a liquid or capsule form, evening primrose and borage oils are usually more palatable in a capsule instead of liquid.
- Add hemp hearts or flax seeds to boost fibre intake (sprinkle on cereal or a salad, add to a smoothie or blend in yogurt)
Omega-3 fatty acids
- They may in the treatment of cardiovascular disease, diabetes, auto-immune disorders, inflammatory bowel disease, cancer, depression and dementia.
- They function to ensure the health of the brain and nervous system, formation of cell membranes, regulate immune system function, help produce hormones in the body, ensure a healthy cardiovascular system.
- Omega-3’s are largely deficient in the Canadian diet
Sources of Omega-3’s include: cold water fish (salmon, mackerel, herring, sardines), flax seed oil (richest plant based source of omega-3, and also a source of omega-6’s), walnuts and soybeans (ALA)
- It is recommended 2-3 servings per week of fish will satisfy this requirement (be careful of fish with high heavy metal content, choose smaller fish or cold water wild fish such as salmon)
- A fish oil or vegetarian omega-3 supplement daily can also be used to boost the levels of these very important fats.
- You can choose to take fish oil or omega-3 supplement in liquid or capsule form. If you take Omega-3s in supplement form, be sure to check with your health care provider first if you are taking a blood thinning medication such as warfarin or heparin.
