The Real Problem With Beef
An extensive study confirms that red meat might not be that bad for you lot. But it is bad for the planet, with chicken and pork less harmful than beef.

The potentially unhealthful furnishings of eating red meat are so pocket-sized that they may be of fiddling clinical significance for many people.
This finding, but released in multiple articles in the Annals of Internal Medicine, is certain to exist controversial. It should certainly not exist interpreted as license to eat as much meat every bit you lot like. But the scope of the work is expansive, and information technology confirms prior work that the evidence against meat isn't nearly as solid as many seem to believe. (While I had no function in the new research, I co-wrote a commentary about information technology in the journal.)
Cherry-red meat has been vilified more than than almost whatsoever other food, yet studies have shown that while moderation is of import, meat tin can certainly be part of a healthy diet.
This doesn't mean that there aren't other reasons to eat less meat. Some point out that the means in which cattle are raised and consumed are unethical. Others argue that eating reddish meat is terrible for the environment.
Recently, meat substitutes accept emerged as a possible solution, only the promise is much greater than the reality, at least and so far.
Burger King and other fast-nutrient chains are trying out Impossible Foods burgers as a vegan answer to beefiness. Let'southward dispense with the idea that this is "healthier" in whatever fashion. The Impossible Whopper has 630 calories (versus a traditional Whopper'due south 660). It too contains similar amounts of saturated fat and protein, and more than sodium and carbohydrates. No one should think they're improving their health by making the switch.
What about the environmental argument? Almost 30 percent of the globe's ice-free country is used to raise livestock. We grow a lot of crops to feed animals, and we cut down a lot of forests to do that. Simply beefiness, far more than pork or chicken, contributes to environmental damage, in office considering it requires much more land. The greenhouse gas production per serving of chicken or pork is about 20 percent that of a serving of beef.
Cows also put out an enormous corporeality of marsh gas, causing almost 10 pct of anthropogenic greenhouse gas emissions and contributing to climate change.
There has been a lot of hope that Beyond Meat's pea poly peptide or Impossible Burger's soy could serve as beef burger substitutes, reducing the need for cows. That'due south unlikely to happen, co-ordinate to Sarah Taber , a crop scientist and food organisation specialist. Basis beef is not the problem; steak is.
"In that location'due south no profit to be made in footing beefiness," she said. "That all comes either from leftover parts one time cattle have been slaughtered for more expensive cuts, or from dairy cattle that have outlived their usefulness. If everyone gave upwardly hamburgers tomorrow, the same number of cows would still be raised and need to exist fed."
In other words, to improve the environs by reducing the number of cows slaughtered, we'd need to find a way to replace the many other cuts of beef Americans enjoy. No lab, and no company, is close to that.
To greatly reduce the reliance on cows, nosotros'd also need to wean ourselves from our loftier level of milk consumption. The increasing utilise of culling milks, similar oats or soy, could assist, but the dairy industry still dominates.
(The dairy industry'southward claims about the health of its product are somewhat overblown. Milk isn't nigh as "necessary for health" as many believe.)
Some companies are researching ways to supplant the more than complex cuts of meat that drive the market. These companies aren't replacing beefiness with substitutes; they're trying to grow information technology in the lab using stem cells.
Tamar Haspel, who writes on food policy for The Washington Post, has said such advances are not likely soon. Nor is it clear that they would have an overall positive impact, unless we are sure that this meat tin exist made in a more than energy-efficient way than we can raise cattle.
Epitome
If meat substitutes won't help in the short run, other things nevertheless might. Some believe that raising cattle on pastures, from nascence until slaughter, might sequester carbon in the soil better than having cows finish their growth on feed lots. Researchers at the University of Florida fence that it can also exist profitable for farmers in warmer climates to do just that. It would require the cattle industry to make pregnant changes, as well as to relocate, and it seems unlikely they'd be willing to do that.
"Grass-feeding cattle without grain is the norm in New Zealand, but almost no ane in the U.s. does it," Dr. Taber said.
Information technology's likewise worth pointing out that it would probably accept longer to raise cows this way, giving them more fourth dimension to emit marsh gas.
Other new developments could help with that problem. Some have proposed farming insects to make animal feed. And feeding seaweed to cows, even in small-scale amounts, can significantly reduce their methyl hydride burps.
One problem with seaweed is that the component that helps reduce methane emissions is classified as a carcinogen past the Environmental Protection Bureau. It's present in small amounts in seaweed, though, and humans have been eating seaweed safely for a long time. A larger trouble is that we are unprepared to farm the unbelievable amount of seaweed it would take to feed all the cattle the globe is raising.
"Picture a seaweed farm the size of Manhattan," Dr. Taber said.
Until people are truly gear up to reduce consumption of dairy or consumption of college-cease beefiness cuts, or to commit to raising cattle differently, it seems unlikely that any of the changes with respect to basis beef volition brand a significant ecology deviation in the near time to come.
That doesn't mean there'south nothing we can practice. I asked Dr. Taber what nosotros might advise people, right now, to help the environment.
"Who needs steak when there's bacon and fried craven?" she said.
