The entire human population is addicted to it..
No. The entire human population is attracted to it, only a portion of them are actually addicted to it.
But, at least with the vegan side, you still avoid the most common cancers.. breast/colon/prostate
No, you don't avoid it, you only reduce the risk. But at least, the reduction is well known.
You should also avoid smoked or burned foods and avoid inhaling fumes from smoking cooking oil.
If we look at --food--, specifically unprocessed foods in the WILD. They're nothing like what we eat and prepare for meals today..
Even most fruits that we eat do not exist in the wild and have thousand year histories of horticulture to make them sweeter and more fragrant.
Modern foods, both natural and processed alike are --Hyper-Palatable--.. Which induce Low-Grade-Addictions.. The effect radically alters our inclinations of not only taste but levels of desire as well..
Humans today are not only satisfied by --A Meal-- they need a SUPER Meal, that looks good and tastes good ONTOP of mere satiation.
This is the case primarily because our ability to make these delights came more rapidly than our physical evolution to cope..
The perception aspect is such that, Once any human is introduced to this never ending supply of _good taste_, this becomes the new bottom line...
If it were a lower line , things would be ok, but the brain is by design adaptive and will trim neuro-receptors upon persistent influx of the good life..
So, the desire upon taste has gone SO FAR, so sweet and so greasy, that it conflicts with our body's ability to physically process them, evidently leading to chronic Western diseases of affluence.. Heart disease/ Cancers
As for Cancer, Cancer is only inevitable under the assumption of a infinite lifespan..
The Modern most common cancers are directly correlated with consumption of animal proteins, and they happen in our Western lifestyles, but NOT in other cultures which eat 0x animals...
The latest info suggest we should not be dying of the common western cancers which are today retiring americans approximately 10-20 years ahead of end of useful healthful lifespan.
