Poor Nutrition
Inadequate or poor nutrition may also reduce a person’s natural immunity. There are specific foods that may trigger boils, for example, dairy products like cheese and milk. Consuming these foods can increase insulin levels which can in turn cause an overproduction of hormones known as androgens, which could result in an outbreak of boils.
It is also important to understand that any food allergies can result in skin conditions, such as boils. Also, it is advised to stay away from foods that contain brewers yeast (pizza dough, cake, bread and other baked goods), foods with added or refined sugar and allergenic foods while treating boils, as they may be the cause or may worsen symptoms.
