Good riddance to foie gras. What about other food made from animal suffering?
Some animals are chewed to death or boiled alive. Others are cut apart or salted to death

Last week New York City Council passed a ban on foie gras, the French delicacy made by force-feeding ducks and geese, to go into effect in 2022.
From the perspective of animal-rights activists this is a long time coming. Foie gras has transformed many animal lovers from conscious consumers to passionate protesters. The production process of foie gras is particularly disturbing: a bird is force-fed three times a day with a long, metal pipe down its throat, all to satiate the gastronomic whims of Wall Street’s 1 per cent in posh Manhattan restaurants.
Foie gras causes understandable outrage. But countless other foods are made from animal suffering. So which are the worst offenders?
In my book The End of Animal Farming I try to determine which foods are most unethical by doing the following maths. First I calculate three things: the calories per animal (you get 200 times more meat from a cow than a chicken); the lifespan of each animal on the farm; and an economic factor called elasticity, which is the estimate of how much a change in quality affects the quantity produced.
Eating just 500 calories of chicken meat leads to three days of factory-farm suffering, and eggs lead to 6.3 days. Farmed fish ranges from 27 to 159 days
Putting these together, we get that eating just 500 calories of chicken meat leads to three days of factory-farm suffering, and eggs lead to 6.3 days. Farmed fish ranges from 27 to 159 days. Compare that to pork at 7.6 hours, beef at 3.8 hours, and cow’s milk at only about 17.5 minutes.
The first thing to notice here is the “small animal rule”. Consuming smaller animals tends to lead to far more suffering per calorie, because it takes far more animals, outweighing most other factors. In fact, chickens and fish make up 95 per cent of all farmed animals. This is worsened by the fact that small animals often endure worse living conditions because they are so easily factory farmed.
The second is that the differences are huge. Eggs lead to hundreds of times more direct suffering than milk. If someone eats beef and drinks milk but cuts out all other animal products, they could have more than 99 per cent of the direct impact of a vegan diet.
But what about less common foods like foie gras? Less data is available, but we can cautiously extrapolate the small-animal rule. Because foie gras is a small number of calories per animal, and the suffering per animal is clearly immense, it is certainly near the top of any list of the cruellest foods. On the other hand, although the baby calves used to produce veal endure emotional and physical confinement, they are slaughtered when they weigh about 320kg, 80 times as much as the average meat-chicken slaughter weight of 4kg. So veal’s “suffering per calorie” is not as large as you would expect based on the emotionally fraught images shown by animal activists.
One of the worst ways for an animal to die is being chewed to death while it’s alive. This practice is particularly common with aquatic animals like fish and octopus and relatively small animals. The biggest suffering per calorie may come from the tiniest animals, such as a popular Chinese dish called “drunken shrimp”. A large number of tiny shrimp are submerged in alcohol and eaten alive; they survive long enough to squirm in the mouth. Other aquatic animals are boiled alive, ripped or cut apart, or even salted to death.
Of course, there is probably a significant difference in chicken and shrimp sentience – the ability to experience feelings like happiness and suffering. Shrimp certainly have simpler nervous systems – consisting of only a few ganglia – but with our limited knowledge of how sentience manifests, can we really justify a claim that they are only a thousandth as sentient?
There may be one exception to the small-animal rule: immobile bivalves – oysters and mussels – are probably not even as sentient as shrimp. The most sophisticated behaviour, indicative of sentience, is that mussels can attach themselves more strongly to the ropes they grow on when they detect chemicals secreted by common predators. But even plants exhibit similar behaviours, such as phototropism, or growing in the direction of light.
Some thoughtful vegans are switching to the ‘bivalvegan’ diet: avoiding meat, dairy and eggs but making an exception for oysters and mussels
Some thoughtful vegans are switching to the “bivalvegan” diet: avoiding meat, dairy and eggs but making an exception for oysters and mussels.
Of course we also need to consider environmental impacts and factors such as convenience. If you switch to a “vegan-except-beef-and-milk” or “bivalvegan” diet, you might spend a lot of time explaining your dietary decisions. On the other hand, you might have an interesting conversation if you explain your diet comes from calculations of “suffering per calorie” or a “small animal rule”, which could seem more rational and level-headed than the usual stereotypes.
There are too many factors to dive into here. But if we’re banning foie gras, there’s a good case for banning other foods made from birds, as well as fish products, and definitely any food that involves eating live animals. Then again, with plant-based foods getting better and cheaper every year, and cell-cultured meat right around the corner, maybe it’s time to stop eating animals altogether. – Guardian
