Digestion and acne

OK, let's set bacteria aside for a while and take a look at how food is digested.
Digestion is unbelievably complicate process, and I doubt that anybody understands it perfectly. However there are few simple basic truths that help us. First of all, complete digestion requires the help of multiple enzymes. Some of these enzymes are manufactured in your body, some we have to get from the food we eat. Secondly these enzymes are very delicate and are completely destroyed by processing and/or cooking.

Thirdly these enzymes are activated only under certain conditions (in most cases they require certain pH-value).Finally your body can not use food that is not completely digested.
Partially digested food passed through your GI track but it can't be utilised by your body.
Undigested food passes through your stomach and small intestine to your colon. Your colon is like a waste management station.

Whatever food has not been digested in your stomach and small intestine is handled in your colon. Your colon absorbs what nutrients
it can from food passing through. Rest gets dehydrated, compressed to faeces and expelled through rectum.

Now your colon walls are lined with protective mucus that prevents harmful bacteria and toxins in your colon from entering your blood
stream. In healthy colon this mucus is mainly colonised by beneficial bacteria, but it also contains harmful bacteria.

Undigested food creates an imbalance in gut flora.

Harmful bacteria feast on undigested food in your colon. Undigested food putrefies and ferments in your colon. This putrefaction creates many toxins as by product.
It’s much like what happens in the garbage bin in your kitchen.
Leftover food and trash starts to rot and before you know it stinks like hell.

The only difference is that your colon has much more bacteria than your garbage bin has. Your colon is also warm and humid, which makes it an ideal environment for bacteria to strive.
If this would happen only once in a while the beneficial bacteria in your colon would be able to keep the harmful bacteria at bay and repair the damage toxins have caused.

However, if this onslaught is an everyday event continuing week,months and even years it has dangerous consequences.

With abundant food and fertile environment harmful bacteria in your gut multiplies in number and gain larger and larger foothold in your colon.
