But, she said, doughnut fans could gain about 15 pounds by the end of the year if they eat one glazed treat a day without changing their diet or exercise habits.
"I'm sure that's not your intention," she wrote in a series of tweets that that drew some critics.
So what is the nutritional information for a glazed doughnut from the company known for its enticing "Hot Now" signs?
Each has 190 calories and 10 grams of sugar, according to the company. It has five grams of saturated fat, which accounts for 25% of the daily value based on a 2,000-calorie diet.
Eating too much added sugar or fat could put people at risk for high cholesterol, diabetes and other serious medical conditions, according to health officials.
Some social media users argued it's everyone's choice whether to take Krispy Kreme up on its free doughnut offer after getting vaccinated. Among them was a woman who said she survived COVID-19.
"If it has the hope of helping even one single other person not endure what I did, I'm gladly being vaccinated," she wrote on Facebook. "So you do you but don't whine if (Krispy Kreme) chooses to reward those of us who want to see COVID die by whatever means necessary."
Krispy Kreme did not respond Wednesday afternoon to a request for comment.©2021 The News & Observer. Visit at newsobserver.com. Distributed at Tribune Content Agency, LLC.
