/\ Well as long as you accept that it might come, and the less you care about what you eat that possibility increases exponentially, then that's something. But the thing is, if you wait until you need to change because it's causing problems, it's going to be a lot harder than if you realize way before you get to that point and change because you WANT to, to avoid it.
As for linking diet and happiness, you guys know better than that. Foods that are bad for you, fast foods especially, things high in salt, sugar, fat or all three, are extremely addictive. Obviously caffeine too, another staple of a lot of people's diets (and just so you know i'm not just trying to preach, i've had a mild caffeine addiction myself....I need to ease up on the energy drinks)
You build this stuff up in your system, and it's like any other drug, you go without it, and you'll have withdrawals that negatively affect your mood, make you unhappy and depressed.
So masta, your point about people having as much joy from unhealthy behaviour, I'd counter that that joy can often be a false one. Heroin addicts are joyful when they get a hit too.... but I'm seriously hoping you don't condone anyone going out and shooting up.
Food's no different to drugs. People get addictions and people die of heart attacks, diabetes, obesity, and shit like BSE and in this case, Salmonella, because they don't give a shit or bother to educate themselves.
And there's social implications. If you eat shit all the time you get sick more often. Jokerman has posted links before about how commonly eaten meats reduce your body's immune system. You're eating shitty fast food meat on top of that and it ain't gonna help. Nobody enjoys being around people who have colds and are coughing and sneezing all the fucking time. I know I don't. Obviously that's extreme but shit, since I went vegetarian and now vegan, I just don't get sick. I didn't get sick once in the whole of 2009 and I had a mild cold earlier this year that lasted less than 2 days. Whereas the people I know eating KFC all the time are getting like 4-5 colds a year.
Smacky you said you had an Egg McMuffin or something. You think that's the best source to get an egg from if you do eat eggs? Is that egg gonna have come from a nice empty field or a fucking disgusting factory farm where the chickens are all diseased, pecking each other to death, covered in shit, stuffed in tiny cages and being injected with growth hormone so the farmers are making more profit from the meat? I mean, damn. It's not that difficult to figure out. Are the things posted in this thread gonna apply more to the low quality factory farm eggs or more expensive, free range, etc, one? Do I even have to ask that?
I'm a vegan so obviously I have issues with meat and dairy in general. But fuck, if you're gonna eat them at least pay more and get a quality product and not the scrapings of the barrel.
It ain't even like you are broke and have to survive on 99cent McWhatever the Fuck's, you drive a BMW. Is the vehicle you drive more important than what you put into your body on a daily basis? Those priorities are twisted the fuck up if that's the case.
