Gimme some sugar, baby.

We have alluded to the nutritional atrocity that is high-fructose corn syrup (HFCS),  in the past, but now there’s a fair bit of clinical ammunition to back particular assertion that up.

And by “fair bit,” we mean “a couple of headshots using a railgun with Quad Damage.”

The BFG10K in question was some research done at Princeton University, which studied weight gain in rats. Using two different control groups – one eating plain rat chow, and one getting rat chow and a sugar-water concoction approximating a soft drink – rats that were washing their kibble down with a HFCS-sweetened beverage gained much more weight, as well as exhibited a greater number of markers for serious health issues in humans. These markers include elevated levels of triglycerides, more visceral fat, and the beginnings of what is called “metabolic syndrome” (in a nutshell, this is the body becoming less-sensitive to insulin; in other words, pre-diabetic). How much more weight? Nearly fifty percent more than the rats getting the same number of extra calories from drinking sugar water.

Back in the late 1980′s Science Fiction and Fantasy author George R. R. Martin cobbled together a group of talented writers to create Wild Cards, a series of alternate history novels set in a universe where super heroes were real. One of the recurring characters in the series was a man named Croyd Crenson, alternately referred to as The Sleeper. In the Wild Cards universe people who were exposed to a virus had a chance to either die, become horribly deformed, or develop extraordinary abilities. The Sleeper was unique in that every time he fell asleep he would be infected with the virus anew, awaking in an entirely different form. Convinced that one day he would draw the “Black Queen” and die as a result of his re-infection with the virus, Crenson fought sleep for weeks on end.

Needless to say, this made him a bit crazy.

As anyone who has seen a Nightmare on Elm Street film can attest to, sleep is important (unless, that is, a scary dude who is covered in burns and has razors on his fingers is going to kill you in it). Going without sleep for long periods of time can have very negative effects on the psyche, but many of us aren’t likely to find ourselves in those kind of situations. What we do commonly face, however, are situations in which we simply do not get enough sleep. The average adult gets about 7 hours of sleep a night, but most studies suggest that in order to be fully rested they should be getting 8. Those numbers come from a study in Consumer Reports back in 1997. Chances are that if you did the same study today we’d probably be getting even less sleep.

One of the reasons? iPads.

I have many fond memories of my school days. I remember my friends and some of the teachers I had that really made a difference in my life. I remember all of the awesome things that I got to experience at the arts focused high school that I went to. I remember how fun my senior prom was, and how thankful I was that my date for the evening had convinced me to go. I even remember how much I just enjoyed learning new things, but that may be a case of me looking back with rose-tinted glasses. If my grades were any indicator learning was the last thing on my mind in school.

What I do not have fond memories of, however, were the school lunches. In fact, I distinctly remember hating the cafeteria so much that I never set foot in it once after my Freshman year in high school.  (My friends and I would either brown bag it or go without and hang out in the theater or a sympathetic teacher’s classroom.) Not only was the threat of bullying higher in the loosely supervised cafeteria, but the food was horrible. Our school’s gastronomical oddities included strange, pinkish meat on rectangular slices of pizza, spaghetti with thick, rubbery noodles coated in disgustingly sweet sauce, and cheeseburgers made from some kind of textured vegetable protein that were often dotted with a slimy gray substance.

The school cafeteria was a pit of doom that smelled of death and sadness. It was my version of Hell, and a few years ago when I sent to my son’s school to have lunch with him I confirmed that nothing has changed. In fact, there were a few items there even more disturbing than I recalled.

What I didn’t know, though, was that the food being served in our schools was not just a threat to the emotional and physical well being of the poor children who actually have to eat it. The problem, it turns out, is far more acute than bad taste.

Playing with fire may have had positive evolutionary consequences. (Photo courtesy of blmurch on Flickr)

Fire is a frequently-invoked metaphor when it comes to fitness pursuits – “burning passion,” “heat of competition,” and so forth. However, there is some very interesting research that suggests that we, as a species, are as intellectually awesome as we are because our ancestors emulated Beavis and Butthead, and kept playing with fire. Professor Richard Wrangham‘s thesis in his book, Catching Fire: How Cooking Made Us Human, is that it was cooking our food that allowed us the freedom, in terms of both time and energy, to evolve the large, spicy brains we enjoy today.

If the zombie apocalypse comes, make sure stock up on flamethrower ammo, because fire is both the reason we’re delicious, as well as an excellent protective measure.

Tell me why, oh why, are my genetics such a bitch?

- Shiloh from Repo: The Genetic Opera

The 1997 movie GATTACA portrayed an ugly future where people were pigeon-holed in society based upon their genetic make up. In order to live up to his life-long dream of being an astronaut, Ethan Hawke’s character in the movie had to assume the genetic identity of another man (played by Jude Law) who did not suffer from the same genetic impurities that Hawke did. Hawke was considered to be an ‘in-valid’ – someone who would never succeed in life because his genes would prevent him from doing so.

I don’t want to give away too much of the plot, but if you understand Hollywood at all, you can probably assume that one of the central themes in the story is that our genetic make-up does not necessarily have to determine our fate. Yes, you might be born with some kind of flaw in your DNA that makes you more likely to suffer from heart disease, but that doesn’t mean you’re necessarily going to.
