Candida is a type of yeast and is the most common of the fungal infections throughout the world. We feed this yeast every time we eat anything that contains sugar. That is their food. They are very difficult to kill. They thrive in an acidic environment. A poor diet is also a great way to help them thrive in your body. They are very opportunistic. When they finally present on your toe nails that is after a long battle and the system can no longer contain them. Prescription anti-fungal medications are generally ineffective and sometime quite dangerous on your organs – especially your liver. If you have cravings for sugars, pastas and carbs in general then you most likely have some degree of candida in your system. Insomnia, itching, food allergies and sensitivities, dry skin and cloudy urine are other indicators as well.
