Some people can eat nothing but unprocessed foods, exercise every day, etc. etc. and still drop dead of a heart attack while running on the treadmill (actually happened...and the guy was a doctor).
One of my uncles went the same way... relatively thin and fit and athletic (and a good bit younger than my dad who was smart enough to get on blood pressure medication since he was 25; some people simply are predisposed to cardiovascular difficulties, even if they can be dramatically exacerbated by poor diet), he'd just finished a workout at home, descended a flight of steps, stood there for a second in front of his wife, then pitched forward into the carpet and was dead as soon as he found the floor. The culprit was all the soda, butter, and steak and too little vegetable matter.
Still, what you suggest is ludicrous. You know what... it's POSSIBLE that I could win the lottery if I played. This does not mean I should stop working for my income and spend every negative cent I have (re: live large off a credit card.) Similarly, based on the odds that an oncoming train MIGHT derail before hitting me, I'm not sure I would remain sitting on the train tracks on the assumption that it will. The healthiest doctor in the world might also be hit by a meteor and have is head caved in. None of these things can do anything to curtail the fact that if you stuff yourself full of junk and poison your health will be much less than it would be if you ate good food... and when the hurdle to make to eat good food is essentially no hurdle at all, but simply being AWARE, it's less than unintelligent not to.
I don't understand how people CAN'T take it seriously... in large part because it's so damn easy to deal with, and there are ~no~ negative effects to doing so. I was overweight... it made me feel sick, tired, isolated, ugly, unhappy, etc etc. Not just from being overweight, but because these kind of foods 'starve the mind' and improperly fuel the body such that not only was I always craving, but never being satisfied or feeling very good. Cutting out the HFCS instantly changed that and made weightloss nothing more difficult than having patience, period. I didn't stop eating sweets... I didn't stop eating the occasional pizza or hamburger (feh, a home-made burger clocked in at a third of the calories and bad stuff that a fast-food version had, and tasted better besides!) I've lost 110lbs so far (only 20 to go!!); it didn't take any effort or concentration or sacrifice... just time and being aware of what it was I was eating. Have you looked at the labels of the 'smart ones' and/or weight-watcher prepackaged meals? They're somewhat rationally proportioned, sure, but they're just as bad and you feel famished shortly after eating them (making it easy to go back for more, which is GREAT for their profit margins, but totally blows the whole point of the program (assuming the ), whereas going to the farmer's market, and getting some chicken or beef, and cooking my own meal produced something amazingly tasty by comparison that did not leave me feeling dissatisfied AND let me drop a third of my body mass. My legs don't chronically ache anymore; I don't have constant headaches; I don't roll fitfully in my sleep due to rogue pains; I don't feel sluggish and tired and distracted and ugly. Since you naysayers seem to cling to your 'one anecdote that disproves the million data points of research' meme, then take the above as an annulling anecdote to yours. I have firsthand experience with this that none of you can explain away. I wouldn't trade this for any amount of junk food.
Meanwhile, there ARE other consequences! My insurance premiums are more than double what they would be if my entire nation ate rationally, because the chronic side effects of eating this crap are EXPENSIVE and REPETITIVE, and instead of eating right, we MEDICATE away the symptoms rather than just resolve them outright... and that's incredibly expensive, too. That's a couple hundred bucks a month I can't spend on things I'd rather spend it on... because so many other somebody-elses are taking your advice. I'll be the first to argue for modest-taxation-in-the-name-of-my-culture-seeing-to-the-benefit-of-everyone-else-who-is-also-a-member-of-it, but that doesn't mean I think I should be paying extra so $entity can be a lazy ignorant sloth-glutton who doesn't even know there's better tasting food out there.
Good food tastes good. Eat an apple... seriously. Pineapple... honeydew. Strawberries and blueberries. Hell... almonds and walnuts contain the ORIGINAL chemical that is, it is dumbed down less effective expensive form, marketed as LIPITOR to help alleviate blood pressure issues often exponentiated by poor diet in the first place. Almonds taste better than lipitor. A lot better. What's more... pounding the almonds is a self-limiting affair since they are SATISFYING, unlike anything choc full o'HFCS.
Any argument against eating good food is specious at best. You feel better, live longer, and keep more of your hard earned money for much more enjoyable things than getting medical treatment.
