In The News: Soda

Today's alarming headline arrives courtesy of the journal Circulation, which published a study concluding that all sodas (yes, including the diet varieties) appear to increase risk factors for heart disease and diabetes.

“Adults who drink one or more sodas a day had about a 50 percent higher risk of metabolic syndrome – a cluster of risk factors such as excessive fat around the wait, low levels of ‘good’ cholesterol, high blood pressure, and other symptoms.”

Is soda the new trans fat? Not quite – I don’t foresee a ban anytime soon (nor would I condone one).

While I would never recommend that a non soda-drinker start gulping down these sugary/aspartame concoctions, I also would not tell someone who enjoys the occasional fizzy sweet drink to give it up entirely.

The real issue here, I believe, is what is being eaten in conjunction with these beverages.

Think about it. What do the overwhelming majority of people tend to eat alongside regular or diet soda? Potato chips, French fries, hamburgers, pepperoni pizza, buttery popcorn, tortilla chips with cheese dip, hot dogs, candy, etc.

I’ve rarely seen someone accompany a fruit salad, a bowl of oatmeal, or a yogurt parfait with an ice cold Coke.

It’s very possible that what this study simply reveals – not too shockingly -- is the effect junk food has on our bodies.

updated research review of 2004.07.16: Murray 2006.05.11

Dark wines and liquors, as well as aspartame,
provide similar levels of methanol,
above 120 mg daily, for long-term heavy users,
2 L daily, about 6 cans.

Within hours, methanol is inevitably largely turned into formaldehyde,
and thence largely into formic acid -- the major causes
of the dreaded symptoms of "next morning" hangover.

Fully 11% of aspartame is methanol -- 1,120 mg aspartame
in 2 L diet soda,
almost six 12-oz cans, gives 123 mg methanol (wood alcohol).
If 30% of the methanol is turned into formaldehyde,
the amount of formaldehyde, 37 mg, is 18.5 times the
USA EPA limit for daily formaldehyde in drinking water,
2.0 mg in 2 L average daily drinking water.

Given the observational nature of the present study, we cannot infer that
the observed associations are causal. As noted above, it is conceivable that residual confounding by lifestyle/dietary
factors not adjusted for may have contributed to the metabolic
risks associated with soft drink intake.

That's not much of a study.
