How do good bacteria in our body prevent bad bacteria?

[Skhandelwal]

Well...what about airborne bacterias? They come to you when you inhale....where do they come from? How can I avoid being exposed to them?(what about airborne viruses!)

[Jorge1907]

Again - you can't avoid them and in fact vyou are evolved to withstand them. Relax - you'll survive.

I think the number of good or harmless bacteria is higher as compared to bad/ harmful ones. Thus they compete and win the coverage over food, shelter for survival. Thus outgrow. Also the body conditions are more favourable to good ones as compared to bad ones.

I am just trying to make all the odds toward me....why is rotten food bad for us?(good bacterias developing?) Why is living w/ plants bad for us?(if good bacterias are good for us...then when we live in a situation where bacterias can develop...we face more problems....may be b/c although the odds remain the same...the number of bad bacteria increases.....)

Also....I understand I'll survive...but I am just trying to get as close to perfect health as possible and for that....how do I avoid being exposed to viruses....since our bactorial layer doesn't stop them....they can just get past anything....

The taste of it for one... you would at the very least aggree with that point Jorge1907?

[Jorge1907]

You mean agree? Sure - taste esp smell of rotten food is aversive but the sensations of sweet, bitter, salty etc are not of necessity such signals.

Where do you get that living with plants (whatever that means) is dangerous?

Maybe you should tell us about your situation - one assumes you live in the developed world and maybe that's not the case.

Guys - take a look at the NIH Human microbiome project (link below). It's based on the concept that microbes are part of our cellular composition.

No I do....but plants require soil, which requires water, and everyone knows that collected water gives birth to bacteria...although UV rays kills all of them...but on a snowy season(since they are inside...they will survive) They are bad for me.

Also, If my eyes, mouth, ears, penis, and nose(all the opening in body-wounds as well I guess but they are conditional) have bacterial colony which stops bacterias from developing...is it good for me to brush and wash those parts?(I mean animals don't brush...but they don't get any dental problems...do they?)

And finally, I guess I understand I can't runaway from airborne bacteria...but I can avoid being at places that might have bad airborne bacterias(fungus, mold, etc.) Which is why I was asking what normally causes those....b/c not all of them stink....(like being around a sick person) Which is why I would like to understand in more detail how rotten food actually affects us.(if one doesn't care about taste)

Sorry to break the news to you but normal people can stand the smell but not the taste.

[Jorge1907]

Then don't eat it
