• Starbucks is bringing back its S'mores Frappuccino to its summer menu.
  • A grande size S'mores Frappuccino has 67 grams of sugar and 12 grams of saturated fat.
  • We asked a dietitian to break down the ingredients and nutritional information to help you make healthier choices.

There's no Frappuccino that screams summer quite like Starbucks's beloved S'mores Frappuccino, which today makes a comeback on the coffee giant's menu, along with several new food and drink items.

Topped with a pillowy marshmallow whipped cream, crumbled graham crackers, and a milk chocolate drizzle, this creamy concoction may seem like the perfect brew to sip on to quell sweet cravings and get your caffeine fix. But before you make it your morning pitstop or afternoon pick-me-up, here's something that'll make you gulp: The grande size with whole milk has 67 grams of sugar—that's 17 teaspoons of sugar. Yikes!

S'mores Frappuccino nutrition

To help you make more health-conscious choices, we asked Bonnie Taub-Dix, RDN, creator of BetterThanDieting.com and author of Read It Before You Eat It: Taking You Label to Table, to break down the nutritional information and ingredients in the S'mores Frappuccino so you know exactly what you're getting into.

Nutrition information per 16-ounce serving: 490 calories, 20 g fat (12 g saturated fat, 0.5 g trans fat), 210 mg sodium, 73 g carbs (0 g fiber, 67 g sugar), 5 g protein

"Though I certainly have a few favorite beverages and snacks from Starbucks that hit the spot for a quick morning breakfast or afternoon pick-me-up, it might be a good idea to treat it more like dessert than a drink," Taub-Dix says.

To give you some perspective on what these nutritionals mean, we compared the S'mores Frappuccino to Krispie Kreme's original glazed donuts, which has 10 grams of sugar in one serving. That means you can eat a little more than six whole Krispie Kreme glazed donuts—more than half a dozen—to get the same amount of sugar you're having in a grande S'mores Frappuccino.

It also has 12 grams of saturated fat, which is 60 percent of your daily value. But the American Heart Association recommends aiming to have only 5 to 6 percent of your calories from saturated fat. Moreover, there half a gram of trans fat—which are partially hydrogenated oils that can raise your LDL cholesterol levels.

So if you want to cut back on the fat and sugar, Taub-Dix suggests making your own at home: "If you're willing and creative, you can throw together a S'mores Frappuccino of your own at home by adding some mini marshmallows, a spoon of chocolate sauce, a drop of vanilla extract, milk of choice, and cracked ice to your coffee (graham cracker on the side).

What’s the healthiest way to enjoy the S'mores Frappuccino?

Some things you can do to lower the calorie count, as well as the amount of saturated fat and sugar, is to choose a tall size and go for 2% or nonfat milk instead of whole. Starbucks also offers almond and coconut milk for its dairy-sensitive customers, but it's likely that they're not the unsweetened versions so be aware when ordering.

When in doubt, you're actually better off picking up another one of the coffee giant's healthy and low-sugar Starbucks drinks.
