Pregnant women who supplemented with fish oil reduced the severity of atopic dermatitis (eczema) during the first year of life.    Other fats and oils have also been looked at for relieving eczema, including evening primrose oil. 
The gut microbiome refers to the trillions of bacteria, fungi, and viruses living in the gut. There’s a strong connection between gut health and skin health. When your gut’s microbiome is out of balance, your skin’s microbiome is probably out of balance too, leading to an overgrowth of opportunistic bacteria and a die-off of beneficial bacteria.
Preliminary studies show that certain probiotics in the Bifidobacteria and Lactobacillus family could potentially improve the clinical effects of eczema in children and adults. Higher microbiome diversity is associated with better health, meaning the more different types of microorganisms in your gut, the better. Fascinating research on the microbiome and how it affects overall wellness is ongoing. This is all the more reason to consume varying foods, probiotics, and fermented foods.
Metabolic Syndrome and Obesity
Skin conditions like psoriasis might be associated with increased rates of obesity and metabolic syndrome. A ketogenic diet is renowned for weight loss, boosting metabolism, and normalizing hormones and blood sugar. When hormones, metabolism, and blood sugar are out of whack, the body often shows signs that could manifest as inflammation of the skin and skin rashes.
Glycemic Load and Sugar
It’s no secret that inflammatory sugar worsens acne, and other skin problems don’t seem to be much different. Studies show diets higher in glycemic load and dairy could be associated with worsening acne. The standard Western diet is sugar-loaded, but foods higher on the glycemic index are off-limits on keto, which could be one reason why skin condition improves on keto.
How Does Eczema Respond to Diet?
In summary, several factors drastically affect your skin and immune health, such as:
- Hormonal deficiencies
- The microbiome
- Food allergies
- Glycemic index and blood sugar
To help manage eczema, people have integrated different types of ketogenic diets, including low-histamine, gluten-free, and dairy-free.
Some research and anecdotal evidence show a ketogenic diet could improve eczema, but more studies are necessary. Keto could be useful for this skin condition for several reasons, as it:
- Requires ditching inflammatory foods like sugar, lowering inflammation
- Improves the microbiome
- Increases your intake of healthy fats and omega-3s
- Ensures sufficient protein intake
- Increases antioxidant intake
If you’re unsure, have questions about eczema, or if you’re considering diet and lifestyle changes, it’s always best to visit your dermatologist or healthcare practitioner.
