Skin diseases are prevalent among pets, accounting for up to 25% of cases seen by small animal veterinarians. This article explores the nutritional dimension of skin health, emphasizing the role of essential fatty acids, particularly omega-3s and omega-6s, in maintaining optimal skin and coat quality.
Understanding Fatty Acids
1. What is a Fatty Acid?
- A fatty acid is a long carbon chain with an acid group on one end and a methyl group on the other.
- Saturated fats (solid at room temperature) are typically derived from animals, while unsaturated fats (liquid at room temperature) come from plants.
2. Saturated vs. Unsaturated
- Unsaturated fats can be omega-3 or omega-6 fatty acids, essential for structural components in the body.
3. Types of Fatty Acids
- Omega-6 fatty acids (n-6): Linoleic acid, gamma-linolenic acid, and arachidonic acid.
- Omega-3 fatty acids (n-3): Alpha-linolenic acid (ALA), Eicosatetraenoic acid (EPA), Docosahexaenoic acid (DHA).
4. Food Sources
- Omega-6: Evening Primrose oil.
- Omega-3: Cold water fish oils (rich in DHA and EPA), flax seed oil (rich in ALA).
Should We Supplement Essential Fatty Acids?
1. Omega-6 Fatty Acids and Dandruff
- Some dogs with seborrhea (oily, dandruffy skin) may benefit from additional omega-6 fatty acids despite a seemingly complete diet.
2. Anti-Inflammatory Effects of Omega-3
- Omega-6 fatty acids in cell membranes can lead to inflammatory substances.
- Supplementing with omega-3 fatty acids can reduce itching, inflammation, and improve conditions like arthritis pain.
3. Challenges in Determining Supplement Amounts
- The optimal ratio of omega-6 to omega-3 in supplements is uncertain.
- Clinical research complexities arise due to varied pet diets in studies.
Conditions Benefiting from Omega-3 Supplementation
Research suggests that omega-3 fatty acid supplementation can be beneficial for:
- Renal (kidney) insufficiency
- Heart failure
- Lymphoma
- Airborne allergies
Ongoing research explores the potential of omega-3 supplements in treating various organ system diseases. The supplementation appears to be safe and promising, opening avenues for further exploration. Stay tuned for emerging research in this field.
