Four reasons why high-fructose corn syrup is probably not the Devil

Four reasons why high-fructose corn syrup is probably not the Devil: “church+lady.jpg

I’ve been curious for a while now about the proven differences—or lack thereof—between current boogeything high-fructose corn syrup and sugars, in general. I haven’t had a chance to do any heavy reporting on the subject, but, the more of other people’s reporting I read, the less worried I am about the stuff. Here’s a few of the key things I’m learning:

1) Diets high in sugars—all and any kinds of sugars—are bad for you. If high-fructose corn syrup is a bigger problem than other sweeteners, it’s because the stuff is so cheap that it enabled food companies to add delicious, delicious sweetener to all kinds of things that might not otherwise have contained it. But that’s a function of economics, not chemistry. In fact, high-fructose corn syrup isn’t the only “added sugar” in use. It makes up about half the added sugars in processed foods. The others—beet sugar, cane sugar, etc.—still rack up calories and are still no good.

2) Sugary beverages are a key factor in rising obesity rates. They happen to be sweetened, usually, with high-fructose corn syrup. But, again, that’s because it’s the cheapest sweetener. It’s probably not the specific sweetener that’s the problem here, but the fact that Americans drink a lot of sugary beverages. We’d be seeing a problem from over-consumption even if the sweetener was sugar.

3) The few studies that have turned up evidence for corn-syrup specific weight gain have had inconsistent results. Other studies have demonstrated potential health problems linked to consumption of fructose compared to other forms of sugar—but fructose isn’t something that’s specific to high-fructose corn syrup. In fact, high-fructose corn syrup has less fructose than a lot of other sweeteners. We only call it “high-fructose” because it’s got a higher fructose-to-glucose ratio than straight-up corn syrup.

4) One of the sweeteners that has way more fructose than high-fructose corn syrup: Agave nectar. It’s somewhere between 70% and 87% fructose, while most of the high-fructose corn syrup you’ll run into is only 55% fructose. Other natural sweeteners, like honey and apple sugar, are also in the range of around 50% fructose. There’s no solid evidence that shows this fructose to be any different than the fructose in high-fructose corn syrup. If you’re really concerned about fructose (And I’m not sure you should be yet. Most of those studies are dealing with pure fructose in test tube or animal research, not real-life mixtures of sugar in human bodies.) your best bet may be maple syrup, which is only 1% fructose.

My take: Keep an eye out for added sugars—of all kinds—in products. If you’re worried about empty calories and weight gain, that’s your real concern. But don’t stress too much about this. Cutting down on the added sugars in your life is good. But a little added sugar isn’t going to kill you. And high-fructose corn syrup isn’t more of a worry than any other sweetener.

As part of the Jewish harvest festival of Sukkot, many Jews build sukkot, huts that are reminders of the ancient Israelites’ nomadic dwellings. My friend Josh Foer of Atlas Obscura co-organized a design competition in New York City to radically re-imagine these temporary structures while still following the traditional design and ritual constraints. Twelve finalists will build their high-concept sukkot in Union Square on September and 19 and 20. The ‘People’s Choice’ winner will then be on view until October 2. All of the amazingly creative, avant-garde designs can now be viewed on the Sukkah City site. Seen here at top left is ‘Gathering,’ by Dale Suttle, So Sugita, and Ginna Nguyen, New York. Top right is ‘Fractured Bubble‘ by Henry Grosman and Babak Bryan. Below those two finalists is one of the 600 entries, titled ‘Hashkiveinu,’ from my architecture student nephew Ari Pescovitz, Kyle Campbell. and Chad Gleason. I’m admittedly biased, but I dig their idea to use CNC machining and prefabrication to make their sukkot a kit. Congratulations all who entered! I’d be thrilled to enjoy a harvest meal in any of these marvelous shelters.

Babbage-esque mechanical computer chip

Babbage-esque mechanical computer chip: “Over at Submitterator, markarayner informs us that engineers at Case Western Reserve University developed a mechanical version of a key component of digital circuits for computers. Their mechanical inverter, the basis for many logic gates, is built from nanoscale levers instead of the transistors patterned onto traditional chips. The research was funded by the US Defense Advanced Research Projects Agency (DARPA) who are after electronics that aren’t prone to failure under high heat, like that inside a jet or rocket engine control system. Te-Hao Lee and colleagues published their work in the current issue of the journal Science. From New Scientist:


Like a telegraph operator’s Morse key, these levers physically make and break contact to pass or block currents.

Application of a voltage makes the levers move under electrostatic attraction. At 550 °C Lee’s team managed to get the inverter to switch on and off 500,000 times a second – performing a computation with each cycle. The faster the switching speed, the zippier the computing. Lee predicts that switching speeds of a billion times a second (1 gigahertz) are possible. That might not sound fast by the standards of desktop PCs, which often run at speeds in excess of 2.5 gigahertz, but for control system applications it’s more than adequate.
