Chandler Swink, 19, a sophomore nursing student at Oakland University went into a coma for a week and died on Wednesday. Doctors ruled that he suffered a severe peanut allergy after eating a batch of peanut butter cookies.

peanut allergy is one of the most common food allergies for Americans that affects about one percent of the American population.

The college student brought himself to St. Joseph Mercy Oakland Hospital on Nov. 18 after eating peanut butter cookies at a friend's house. He immediately injected himself with an EpiPen, but before he even got to the emergency room, he lost consciousness in the parking lot and went into a coma. Doctors said that he suffered from an anaphylactic shock, asthma attack, and cardiac arrest, USA Today reported.

Chandler was pronounced dead at 8:45 p.m. on Wednesday. The family decided to remove his life support after doctors told them that his chance of survival was only two percent.

 "It's been tough on all of us the past few days," said Mike, Chandler's cousin, to the Oakland Press. "It's brought our family closer but we miss him so much."

The latest incident of the peanut butter allergy serves as a reminder for people to be critical of the food that they eat when they have food allergies. Chandler was diagnosed with level six severe nut allergy at age 2.

"You need to take your family members' food allergies very seriously ... You don't need to add almonds or pecans to the food you bring," said Bill, Chandler's father, told the Oakland Press.

An online GoFundMe fundraiser was launched for Chandler to help his family settle the hospital bills.

"Chandler Swink's death is a tragic loss for our university," Glenn McIntosh, OU interim vice president for student affairs and enrollment management, said in a news release. "He was a scholarship student with a passion for learning and had a very bright future. We offer our condolences and stand by to support his family, friends and his girlfriend."
