The Importance of Nutrition in Healing Eczema

Part Three: Essential Fatty Acids and the Omega-6: Omega-3 Ratio

Vegetable Oils and Chronic Inflammation

Essential fatty acids are essential because we must get them through our diet. Omega-6 (LA-

linoleic acid and Arachidonic Acid) and Omega-3 (ALA-alpha-linolenic acid) are imperative to great skin health. ALA needs to be converted in the body to EPA and DHA to be used effectively. Linoleic acid is needed for the inflammatory response and ALA is important for reducing inflammation. It is important to keep these fatty acids in balance to avoid chronic inflammatory disease. Because eczema is an inflammatory condition, it is crucial to make sure these fatty acids are kept at a ratio of 4:1.

In the last 100 years, the ratio of these essential fatty acids has increased in favor of Omega-6 to between 10-20: This ratio predisposes us to chronic inflammatory conditions and allergies. Americans are overconsuming LA mainly from industrial seed oils such as canola oil, sunflower oil, corn oil and soybean oil. Seed oils go through a refining process that requires degumming, deodorizing, and bleaching to make them edible and nearly all restaurants in the United States use them for cooking. Furthermore, studies show that polyunsaturated rich vegetable oils increase the risk of lifestyle diseases such as, Alzheimer’s, diabetes, and obesity. 

Supplementation of Omega3 fatty acids in pregnancy is a necessity for reducing allergic diseases in offspring. In fact, women who supplement with 3,700mg per day of EPA and DHA at 25 weeks’ gestation until 3-4 months of breastfeeding, reduce risk of food related eczema by three-fold. Therefore, ensuring an optimal Omega-6 to Omega-3 ratio before the fetal immune system develops could be an important step to preventing allergic diseases such as asthma and food allergies in children. 4

 

3 Steps to Bring the Omega-6: Omega-3 Ratio Back to Balance

 

Stop cooking with vegetable oils and eating in restaurants that use them

Vegetable oils are highly processed and go through refining which often involves removing essential nutrients and chemical extraction including bleaching. Refining is done to maintain shelf life; however, most of the nutritional elements are lost during this process and these oils tend to oxidize during the heating process. Unfortunately, most restaurants use these oils for frying and cooking at high temperatures.

The best oils for cooking at high heats are saturated because the chemical structure of saturated fats has each carbon molecule saturated with hydrogen; therefore, it won’t become oxidized when heated. Hence, the more unsaturated a fat is the faster the oxidation reaction proceeds. Coconut oil, butter, ghee, lard, and beef tallow are all solid at room temperature and can remain stable when heated above 180 degrees. The chemical structure of saturated fats has each carbon molecule saturated with hydrogen; therefore, it won’t become oxidized when heated.

Monounsaturated fats such as olive oil, avocado oil, flaxseed oil, chicken and duck fats are liquid at room temperature and should not be used to cook over 180 degrees as they will begin to smoke and oxidize (or loss of electrons and an increase of the oxidation state). These types of oils are great for cooking low and slow or used in dressings. 

Finding restaurants that cook with healthy oils in the United States is getting easier. Using the Seed Oil Scout app is a great way to find farm to table restaurants that are cooking with healthy oils. Choosing menu items that are unlikely to be fried or cooked in oils and reviewing the menu before eating out is a good way to navigate the menu when traveling.

 

Add Omega-3 fatty acid foods to your diet including wild caught fish

We begin introducing foods to babies around six months. Some of the best advice I received

from my holistic pediatrician was to start with introducing fat and protein instead of grains and carbohydrates. This way babies begin to develop a taste for healthier, nutrient dense, non-processed foods. He advised us to start with avocados, salmon roe, sardines, and chicken liver.

To this day our daughter loves a wide variety of nutritious foods and is always willing to try something new. Omega-3 fatty acids are essential for skin and brain health. In a recent study measuring serum EPA and DHA, results showed that over 68% of adults and 95% of children in the United States, do not consume enough Omega-3s to meet nutritional guidelines.6 Omega-3 fatty acids are tied to learning, behavior and a reduction in childhood allergies including asthma. 1,7 Omega-3 fatty acid foods to be included in the diet are:

• Low mercury fish including wild-caught: Salmon, Anchovies, Crab, Sardines, Black Cod, Oysters, Shrimp, Trout and Arctic Cod. Wild caught fish are high in Omega-3 fatty acids because they eat algae. Farm raised fish are fed grains and soy and very high in Omega-6
• Grass-fed beef, lamb or veal and pasture raised eggs
• Walnuts, chia seeds and flax seeds (conversion rate to EPA and DHA is low)

 

Omega-6 fatty acids are still important to include in the diet, but they should come from whole

food sources as opposed to industrialized vegetable oil. Whole food sources of Omega-6 fatty

acids to include are:

• Nuts and seeds
• Pastured animals

 

Supplement to Increase Omega-3 Fatty Acids in the Diet

Scientific studies continue to show that supplementing with Omega-3 fatty acids can reduce the production of IgE, the antibodies that cause allergic symptoms in those with asthma. From all the immune cells investigated DHA and EPA have been shown to inhibit the activation of immune cells while promoting some more specific immune functions including destruction of abnormal cells. Furthermore, supplementation has benefits on the brain. Children with ADHD have

shown to have low levels of Omega-3 fatty acids in their cellular membranes correlated with learning and behavior problems. A study in Japan looked at 40 children with ADHD symptoms and supplemented with 510 mg of DHA and 100mg of EPA a day improved outcomes on combined teacher/parent ratings. More and more, studies are showing supplementation with EPA and DHA can improve a wide range of health disorders including Autism, Mood Disorder, Dementia, Dyspraxia, inflammatory issues, and improve brain function overall. 

• Be sure to find a quality Omega-3 fatty acid supplement and store in the refrigerator
• Choose one that is third party tested and free from heavy metals
• The supplement should contain at least 500 mg of EPA and DHA per 1,000mg of fish oil
• Vegans can supplement with a quality algae supplement such as Juice Plus

Lowering the Omega-6: Omega-3 ratio is imperative for the long-term health of our children. The benefits of eating and supplementing with EPA and DHA are widely known. From lowering the risk of cardiovascular disease, asthma, mast cell activation, autoimmune disease, diabetes, dementia, and eczema; it is crucial to begin making this change in your diet for the long-term health of your family.
