One of my favorite memories of my Dad is being out with just the two of us and we took a break for a surprise ice cream cone. Having him just to myself for a bit was pretty rare and to sit in a Dairy Queen somewhere for 30 minutes chatting and having ice cream was the absolute best.
I once quit sugar for 6 months. It was harder than quitting alcohol, nicotine or caffeine. My first super-sweet treat after those 6 months was a donut and it almost made me vomit on the first bite. The dopamine rush quickly overwhelmed my physical aversion.
Anyway, by the time I got to AIT I was so happy to not have to touch any of it, I didn't. So while my classmates went off-post on weekends and got fat on garbage I went out and had fun, but at well at the mess hall.
By the time I was out of the service (2yrs) I hadn't touched sweets/caffeine/crap in almost that whole time. I remember being able to taste the caffeine in sodas(if you've ever drunk ginseng you probably know what it tastes like), and they felt like straight syrup.
Somewhere along the way I had a girlfriend who got me back into them, and they just became a part of my life again.
Now, here I am, 40, getting rid of them again. But now it's worse because I really enjoy my morning coffee and knowing I will be replacing it with running (which I used to love until the US Army), doesn't help my motivation much.
But yea, quitting sugar and caffeine. Smoking cigarettes wasn't this hard to quit :(
During college I availed myself of all-you-can-drink soda, and pretty much stopped drinking milk. Surprise, surprise the change (coupled with stress) resulted in some pretty serious and frequently recurring GI issues.
Finally isolated the cause (docs were useless), went back on a 1+ glass of milk a day practice, and everything returned to normal.
Since then, I pretty much cut soda out of my diet as well. IMHO, if we're looking at it from a caloric perspective, there are a lot more delicious things to spend 140 calories on.
Now as an adult I am happily consuming great amount of Coca Cola, however never developed a taste for Americanized supermarket style sweet treats (Oreos, etc. )
But to each their own. I think this whole guessing the best diet for kids can go any way because it's just one of many factors. Though there are definitely known risk factors, e.g. how drunkenness at a young age greatly increases the risk of alcoholism later on.
If you specifically deny your kids sugar and tell them it's the debbil and all that, you're gunning for the disorder when they finally rebel and try the forbidden carbohydrate.
However, if it's just not a thing. You never point it out, you never mention it, you just don't have sugar around, then they're more geared for the dismissal of it.
