Protein in your coffee? Starbucks pushes new lattes as experts react

Amid online trends focused on boosting daily protein intake, Starbucks is pouring more into your morning cup.

The company announced it is "going all-in on protein" with the arrival of its Protein Lattes and Protein Cold Foam, saying the new menu items provide a "delicious way" for customers to add more protein to their day.

"This is especially beneficial for individuals who may skip breakfast or meals but reach for a coffee instead," said registered dietitian Erin Palinski-Wade, who is based in New Jersey.

Tanya Freirich, a registered dietitian nutritionist in Charlotte, North Carolina, who specializes in diabetes, agreed that there may be some benefits, but cautions that the trend could be fueled by marketing.

"For people who struggle to consume enough protein, the added whey protein in their coffee drink may be helpful," she told Fox News Digital, citing research showing that 70% of Americans are actively trying to eat more protein. 

Starbucks' protein lattes contain between 15 and 36 grams of protein per beverage, according to its website. For comparison, one cup of chopped chicken breast has about 47 grams of protein.

However, Freirich noted that absorption depends on the form of whey used, such as hydrolyzed or isolate, and cautioned that not everyone metabolizes protein in the same way.

Still, neither expert recommends relying on a latte as a meal replacement.

"This added protein does not mean the beverage is a meal substitute, since it would be lacking in key nutrients, such as fiber and antioxidants that you would find in a balanced meal," Palinski-Wade said.

The sugar content is another caveat. Palinski-Wade cautioned that even with the added protein, drinks with large amounts of added sugar can cause blood sugar levels to spike.

Freirich noted that some influencers promote intake far beyond what's necessary.

"People who already have kidney issues should not be overconsuming protein," she said, warning that too much can impact bone density, liver health and kidney stone risk.

Ultimately, Starbucks may provide a convenient protein bump, but both dietitians recommend a food-first approach.

"Lean protein from fish, eggs, chicken, pork and beef can all provide quality protein, while protein from plants - including beans, nuts, seeds and lentils - can be a great way to add protein, along with fiber and antioxidants," Palinski-Wade said.
