Nail fungus, a common ailment, often affects the toenails, though it can also appear on fingernails in more severe instances. While some may dismiss it as a minor cosmetic issue, nail fungus can be indicative of underlying health conditions.
Severe cases of toenail fungus are frequently observed in individuals with diabetes. These patients may also exhibit diabetic neuropathy or foot complications, such as swelling. The presence of fungal infections in such cases suggests a link between the condition and systemic health issues.
Fungal infections, including those caused by Candida albicans, are more common than we think. The human body hosts over 500 different types of fungi. Candida albicans is known for being aggressive, and becomes an issue when the body is compromised. This can be seen in diabetes patients. When they are in recovery, the *Candida albicans* flourishes due to the higher glucose levels that exist within the body. Essentially, fungus thrives in an environment rich in glucose.

The development of nail fungus, regardless of a person’s weight, diabetic status, can often be linked to high glucose levels in the body. Even individuals not diagnosed with diabetes may experience elevated glucose levels. This creates an environment conducive to fungal growth.
When excess glucose is present, it undergoes fermentation, transforming into lactic acid. This acid, being heavier than blood, tends to accumulate in the lower extremities, such as the toes and fingers, due to gravity. The acidic environment damages the nails, leading to fungal infections.
Addressing nail fungus effectively requires managing glucose levels through a balanced diet, such as the 3×1 diet. This can help lower the amount of lactic acid present in the body. In addition, proper hydration and metabolic repair are also useful to stop fungal growth. Topical treatments alone are unlikely to provide a lasting solution, as they do not address the underlying cause of the infection.
