It is not a very well known fact that your diet can be a major cause of your acne breakouts.
This is because this theory has been discredited by both dermatologists, and the acne companies who coincidentally are the ones making money from you spending money on their products.
  The truth of the matter is that diet can and does play a huge role in the production of acne and I will explain how.
Your body digests foods by breaking them down into simple carbohydrates or simple sugars.
These sugars are then sent by your bloodstream to the parts of your body that need energy.
  The problem occurs when you eat a lot of candy, and refined sugary foods.
  When you ingest these into your body, they are already simple sugars which means that your body does not have to break them down and can use them right away.
  Since these types of foods enter your bloodstream all at once and very quickly your blood sugar levels become very elevated.
In an attempt to bring your sugar levels down your body quickly releases insulin, which causes a hormonal imbalance within your body.
  When this hormonal imbalance happens your body will excrete a higher amount of sebum (oily substance) within the skin's pores.
This increase in sebum allows for dirt, dead skin, and acne causing bacteria to gather in the pore thus causing and infection known as a acne.
Eating foods with preservatives, additives, or food dyes can also cause acne as your body considers these things to be toxins.
  Your body will then try to get rid of these toxins any way possible, most will go through your digestive tract however some will be pushed out through your pores.
When this happens it allows for the same bacteria to gather and form acne.
