A look at data on food intolerance from the United States Food and Drug Administration shows that New York City and its suburbs are much more intolerant than other major US cities, particularly the Northeast and the West Coast.
New York City has the highest rate of food intolerance in the country.
More than two-thirds of New York city residents who live in New York state have some form of food-related illness.
For the second year in a row, New York was No. 1 on the list of most intolerant states.
The city is second only to New Jersey on the severity of food allergy symptoms and the prevalence of food intolerances, with more than three in four New Yorkers having at least one food-based allergy.
The number of New Yorkers who have experienced food allergies in the past 12 months is also much higher than the national average, and the rate of reported food-allergy related illness is higher in New Jersey than in New Yorkers overall.
Food intolerances are more common in people who live near a large food processing plant, which has been identified as one of the most important factors contributing to the rise in food intolerance, according to the CDC.
In New York, about half of the people with food allergies have a food-processing job, compared to less than 10 percent in all of the other states in the data.
New York also has the largest number of food processing jobs per capita in the nation.
Although New York has seen a drop in food-borne illnesses over the past year, the rate is still more than double the national rate, according the CDC data.
While food allergies are the number one cause of death in the US, the number of people who have a specific food allergy is more common than the general population, according research from Johns Hopkins University.
The data show that the number and severity of foods allergies are more closely tied to the state of the economy than to their geographic location, according data from the American Heart Association.
The New York Times also found that people who say they are allergic to food are more likely to have an allergy to a variety of foods, such as nuts, wheat, soy, milk, and eggs.
There are about 20 million people in the United Kingdom with an allergy.
The United Kingdom has also seen an increase in people living with food-specific allergies in recent years, according CNN.
A survey of about 1,000 Americans living with an eating disorder found that the proportion of Americans with food sensitivity has grown since 2010.
In 2014, more than 50 percent of Americans said they had food allergies, up from 35 percent in 2010.
Americans living with a food allergy are more than twice as likely as those who do not have a health condition to have a diagnosis of food allergies.
About two-fifths of the food-injury deaths in the U.S. each year are caused by food-induced illness, according The Center for Disease Control and Prevention.
