The glucose does increase the hydration of the mucusu linings, which makes you more resistant to infection, but it seems the larger problem is that many fungi can use ketones for energy, while our defenses require glucose to function at peak effeciency. So swinging away from VLC/ketone metabolism and adding more glucose-based starches can increase the bodies immune response to these invaders, while decreasing the health of the fungi.

Low-carb diets, alas, impair immunity to fungal and protozoal infections. The immune defense against these infections is glucose-dependent (as it relies on production of reactive oxygen species using glucose) and thyroid hormone-dependent (as thyroid hormone drives not only glucose availability, but also the availability of iodine for the myeloperoxidase pathway). Thus, anti-fungal immunity is downregulated on very low-carb diets.

Moreover, eukaryotic pathogens such as fungi and protozoa can metabolize ketones. Thus, a ketogenic diet promotes growth and systemic invasion of these pathogens.

As the fungal infection case studies on our “Results” page illustrate, low-carb dieters often develop fungal infections, and these often go away with increased starch consumption.

Fungi feed on sugar. I'm not sure there's much reasoning behind adding extra carbs if you're functioning healthily. But there's almost certainly some detail in the mirco-nutrient or environmental range which could be improved, and a change of diet would shake things up a bit. Your gut flora don't need to be intentionally fed carbs, but depending on your broth/fermented/just plain dirty food intake there could be room for improvement there. In any event, if it's been a problem for years, it's probably worth trying anything once.

Are you taking any probiotics?

You might need to do a month where you double up the dose of your probiotics (or get a really heafty strain) and add in some other ferments. You can also soak your nails in vinegar, that helps kill the fungi. Then rub on some tea tree oil to the infected areas, let dry - then keep dry until next soak. Consistency is key though, you have to attack it daily!

Fungi lives off sugars. I would think you should keep the sugars extremely low and cut the starches. Maybe one month of this could fix it then you could go back to normal eating and not 'doctoring'.

How's your Vitamin D Status? All my skin-related issues are gone now that I am sufficient in D.
