Haven’t they suffered enough?

Mostly vegan Nanny — that is, Mayor Eric Adams wants New Yorkers to say goodbye to beef and go on a plant-based diet to help save the world from global warming, with the city’s public hospital patients leading the way.

“It is easy to talk about the emissions that’s coming from buildings and how it impacts our environment, but we now have to talk about beef,” Adams said Monday of his greens for green initiative during a press conference at New York City Health + Hospitals Culinary Center in Brooklyn.

To that end, H+H is offering plant-based meals as the primary dinner option to inpatients at its 11 major facilities.

“I don’t know if people are really ready for this conversation,” Hizzoner said, in a dazzling understatement. “[But] we can’t have a level of hypocrisy where we want to ensure that we do make local laws to address the emissions that come from fossil fuel, but not be willing to have a real conversation on what food is doing to us.”

The amateur nutritionist is taking his plant-food obsession to a new level by tying it to a campaign to reduce food-based carbon emissions in city agencies by 33% by 2030 while urging private firms to slash emissions by 25%. 

According to Adams, food sources represent 20% of New York City’s overall carbon emissions — the third largest source behind buildings (34%) and transportation (22%).

The plant-based zealotry reminds some of former three-term Mayor Michael Bloomberg’s health crusades that included banning smoking in bars and restaurants and outlawing trans fat ingredients in restaurants. The courts rebuffed Bloomberg from banning the sale of “Big Gulp” soda drinks.

Curtis Sliwa, the Guardian Angels founder and WABC radio host who was Adams’ Republican opponent in the 2021 race for City Hall, cracked that the mayor should first test his veggie-leaning diet on the thousands of newly arrived, carnivore-loving migrants.

“We know what they’re going to do, right? They’re going to throw it in the garbage. It’s not culturally appropriate,” said Sliwa, who added that there are more pressing matters to deal with — particularly in the city’s medical facilities still recovering from the devastating COVID-19 pandemic.

“We don’t have enough nurses,” he said.

One veteran health care practitioner said Adams’ plan has merit — to a point.

“I think a complete diet is better. A lot of vegetarians are low on vitamin B12,” said Joanne Loo, a veteran nurse who worked at Mount Sinai Hospital during the pandemic and now runs her own medical spa.

Like Sliwa, Loo also said hospital staffing should be a priority.

“Patient safety is still a problem,” she told The Post. “The mayor should work on that.”
