Reducing intake of added oils can lead to a more balanced intake of essential fatty acids, which is known to improve systemic inflammation, lipid metabolism and immune system stability; resulting in less skin sensitivity and healthier sebum composition.
Due to growing concerns regarding diets high in saturated fats, the consumption of vegetable oils high in omega 6 and omega 9 fatty acids has risen significantly.
Unfortunately, this preference for vegetable oils comes with it’s own set of potential draw backs. More specifically, vegetable oils rich in omega 6 fatty acids are now increasingly viewed as pro-inflammatory. Meaning that, increasing their consumption can lead to a general rise in systemic inflammation.
Accordingly, many researchers have correlated the rise in omega 6 fatty acid consumption with rises in malignant tumors, rheumatoid arthritis and autoimmune disease .
- Soybean oil
- Corn oil
- Cottonseed oil
- Grape seed oil
- Peanut oil
- Canola oil
- Sunflower oil
Nonetheless, it’s difficult to say weather or not isolating certain oils is of benefit. Instead it appears that aiming for a general reduction in added vegetable oils and fats may be most favorable .
Diets with a more balanced ratio of omega 6 fatty acids to omega 3 fatty acids have been shown to:
- Improve conversion of linolenic acid to longer-chain omega 6 fatty acids (such as GLA) 
- Reduce levels of systemic inflammation [6, 7, 8]
- Improve blood lipid and cholesterol levels 
- Reduce the risk of developing diabetes [10, 11]
- Stabilize immune system function 
Why It’s Important for Inflammatory Skin Disease
Characteristics most important for individuals affected by inflammatory skin disorders:
- Reduced inflammation
- Improved lipid metabolism
- Improved blood glucose control
- Reduced skin sensitivity and inflammation
- Improved sebum composition and barrier function
Ideas for Integration
- Replace salads with raw vegetables (whole or portioned)
- Avoid dressings and marinades in favor of herbs and spices
- Some studies suggest that reducing intake of vegetable oils is not needed to gain the benefits of increase omega 3 consumption 
- Grass fed animal products have healthier fatty acid profiles, then those on commercial grain fed diets 
- Many convenience foods and ready made meals are high in added vegetable oils
