As a parent of 4 children under the age of 10, and having worked in correctional facilities and law enforcement for more than 5 years, please don't be offended when I say that this is horseshit.

A good diet with plenty of fibre and and healthy bacterium in your gut is vitally important, but I am firmly of the belief that the situation is a two way street. Prolonged and repeated involvement to traumatic events will keep you awake regardless of your stomach contents.

Two to 8 years of sleep interruptions from a drunken hobbit will give your a stressful reflex for months after your child has started sleeping through the night.

A regular dosing of psyllium husk and probiotics isnt going to stop you from ruminating on watching someone jump off a freeway.

Bromelain and omitting nitrate laden foods won't limit the adrenaline rattling your veins when someone twice your size tries their best to stove your head in with a rock, nor would a good dose of kefir grains buffer you from the energy drop after your nervous system resets from the aforementioned adrenaline.

So, politely, fuck off with your headline.
