Sunkist Orange Soda: More Peppy Than Pepsi

January 3, 2013 By Kate Heyhoe

Look closely: Sunkist Orange Soda is even more caffeinated than Pepsi Cola, while Pepsi Max and Sun Drop Citrus Soda zoom to the top of the chart – they’re bubbling close to the FDA’s legal limit for caffeine in soft drinks (71 mg per 12 ounces).

And: Ounce for ounce, Pepsi Max and Sun Drop have twice the kick of Coca-Cola.

How do these numbers compare to coffee? Caffeine in coffee and tea varies, but for this book, the rule of thumb is: an average cup of coffee contains about 100 mg of caffeine, and an average cup of tea contains about 50 mg of caffeine. Starbucks lists their Grande brewed coffee at 340 mg caffeine.

What about the sugar content of caffeinated beverages? The next infographic shows how supersize soft drinks compare in caffeine, sugar, and calories…

Supersize Sodas: Caffeine + Sugar

January 3, 2013 By Kate Heyhoe

The bigger the cup, the more sugar, calories, and caffeine it contains. Here’s a look at supersize fountain drink sizes, using Coca-Cola Classic as an example. (Mountain Dew, Sunkist Orange Soda, and Pepsi contain more caffeine; some drinks have none.) Note that ice in a cup will slightly dilute these numbers.

Energized Number Crunching: Energy Drinks

January 3, 2013 By Kate Heyhoe

I wanted to know how energy drinks compared to soft drinks and coffee in terms of caffeine amounts. After all, energy drinks are sweet, carbonated and refreshing, so it’s as easy to drink them as you would a Coke or other soda. And coffee is still the top banana when it comes to caffeinated beverages, but a Starbucks coffee tends to be more potent than a home brew.

Even though a single “mainstream” energy drink delivers a solid caffeine rush, most fall within levels that health professionals consider safe. However, kicked-up versions of the same brand can more than double the caffeine. And drinking more than one can of any energy drink can push caffeine into risky levels – especially when teens slurp them up like soda.

A “mainstream” energy drink contains 160 mg of caffeine per 16 ounces – according to the American Beverage Association (ABA, the industry’s lobbying group) – or half as much as a “coffee house” coffee (i.e., Starbucks) of the same size. But the ABA doesn’t mention that a regular coffee (the kind you’d drink at the office or brew at home) has about 100 mg of caffeine.

Energy Drinks Compared to Soft Drinks

I compared the ABA’s typical “mainstream energy drink” against other drinks and found:

1 Rockstar or other “mainstream” energy drink (160 mg/16 ounce)

= 5 (12-ounce) Cokes

= 3 (16-ounce) Cokes

= 3 (12-ounce) Mountain Dews

= 2 (8-ounce) Red Bulls

The more powerful version of Rockstar is even more caffeinated:

1 Rockstar 2X (12-ounce)

= half a (16-ounce) “mainstream” energy drink

= 6-pack of Pepsi (12-ounce cans)

So, you could drink 1 “mainstream” energy drink like Rockstar, or 3 Cokes. Or for more punch, you could drink one Rockstar 2X and get the same caffeine as a six-pack of Pepsi, but faster.

I’m not against energy drinks and slurp them myself from time to time. But it’s important for people to have a clear understanding of what they’re consuming, and comparisons like these help frame the whole story.

Calculate Your Caffeine

January 3, 2013 By Kate Heyhoe

The infographic above shows caffeine concentration: it reflects the amount of caffeine per ounce – you can use these numbers to determine how much caffeine you’re consuming. Simply multiply the milligrams per ounce (in the graphic) by the ounces in a beverage.

*Note: Caffeine in coffee and tea varies; amounts listed are average.

Examples:

Mountain Dew: (40 oz fountain drink) x (4.5 mg caffeine per oz) = 180 mg total caffeine

Monster M3 Energy Drink: (5 oz bottle) x (32 mg caffeine/oz) = 160 mg total caffeine

Starbucks Roast Coffee Venti: (20 oz) x (20.7 mg caffeine/oz) = 414 mg total caffeine

Is Caffeine a Drug or a Food?

January 5, 2013 By Kate Heyhoe

Caffeine blocks adenosine receptors, and changes other processes in the brain

Technically, caffeine is a type of psychotropic drug (also called a psychoactive drug). That is, it affects the central nervous system and alters brain activities associated with mental processes, perception and behavior.

Caffeine: Listed or Hidden?

When caffeine occurs naturally (as in coffee, tea, or chocolate), the FDA does not require caffeine to be listed as a separate ingredient. So a Hershey’s Kiss or bottle of Starbuck’s Frappuccino doesn’t need to specify caffeine. Nor does an energy drink when the caffeine is part of a natural botanical source, like guarana or yerba mate.

But when caffeine is present as an additive, the FDA does require it to be listed as an ingredient; this applies to foods, beverages, over-the-counter and prescription medicines, and dietary supplements – which include energy drinks and energy shots – but not to soft drinks.

Sodas are not dietary supplements. Soft drink makers got a special pass from the FDA back in 1980, when they argued caffeine was added just as a flavor enhancer – a claim that appears to be more myth than fact. Consequently, they are not required by the FDA to list the amount of added caffeine they contain, though the amount must not exceed 71 mg per 12 ounces. Only recently do some soft drink makers voluntarily print caffeine amounts on their labels, which we’ll get into later.

A Monster Energy Example

In 2013, Monster Energy – and a few other energy drinks – switched from being classified as a dietary supplement to being classified as a food (or specifically, a beverage). Monster’s formula is the same, and it still loads the same amount of caffeine, but the information on the can is different.

The new Monster can sports a Nutrition Facts panel and adds “CAFFEINE FROM ALL SOURCES: 80 mg PER 8 FL. OZ.”

The old Monster wore a Supplement Facts label and the standard dietary supplement disclaimer that reads “These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.” The old Monster also lists caffeine, but not the amount, and only as an ingredient in its proprietary “Energy Blend,” which also includes guarana, inositol, glucose and other substances.

Here’s what’s puzzling for consumers: Unlike sodas which are limited to 71 mg per 12 ounces, the recategorized new Monster contains much more than 71 mg per 12 ounces; an 8-ounce portion still delivers 80 mg of caffeine. Which points out the flaws in the FDA’s regulations. Many would argue that the fizzy sweet Monster Energy drink tastes and looks just like a soft drink.

Even the FDA’s deputy commissioner Michael R. Taylor says the rules on caffeinated products appear to be outdated, and the agency is looking at ways to revamp them.

Caffeine Confusion for Consumers

So, if it looks like a soda, and tastes like a soda, but it’s more caffeinated than a cup of coffee, it’s probably an energy drink. If the FDA classifies the energy drink as a type of dietary supplement, caffeine may be added in any amount as long as it’s not known to be harmful. (Terms like energy drink and energy shot are purely marketing terms, not FDA categories.)

In the U.S., whenever an energy drink, energy shot and energy gel or other caffeinated edible is approved by the FDA as a “dietary supplement,” it’s permitted to be sold without limits to the caffeine content, because the FDA does not consider them food. So even though caffeine is a stimulant drug, it’s not regulated as a drug by the FDA – when it’s an ingredient in a dietary supplement.

Things get especially murky when you realize that a Starbucks Doubleshot Energy drink is considered a food, while a Java Monster Loca Moca is a dietary supplement, yet both contain the same amount of caffeine in a 15-ounce can.

To the average consumer, they’re all just caffeinated beverages.
