Down the food route

In his latest blog entry, Malachy Tallack charts the course of food from the field to the freezer

There are those who argue that anyone who is willing to eat meat should also be willing to kill it themselves, and I can certainly understand the logic of that statement. There is a huge degree of pretence in much of the food that is consumed today.

The supermarkets are filled with pre-prepared and packaged meat, to which everything possible has been done to try and disguise the fact that it originated from a living creature. But despite that, I’m quite sure that most carnivores, in the right situation, would kill rather than starve. They would just prefer not to. And I don’t blame them.

Killing an animal is not an enjoyable experience, and anyone who does enjoy it should probably not be allowed near animals in the first place. Nor is it something that should be taken lightly.

I suppose the closer an animal is, in biological terms, to humans, the more difficult it must become to harm it. Swatting a bluebottle or squashing an ant wouldn’t trouble too many people’s consciences; killing a fish to eat would also pose little difficulty for most. But as you climb the evolutionary ladder, it gets more complicated.

Croft lambs from Fair Isle are sent to mainland Shetland to be sold. From there, most will be shipped to Scotland and sent to abattoirs there. The hill lambs however, stay on the isle, and are killed and eaten by the crofters themselves.

To have a freezer full of meat that you can guarantee has had a good life, and that will also taste fantastic, is a huge privilege, and is one of the greatest benefits of crofting. Indeed, it is this self-sufficiency which is meant to be at the heart of the crofting lifestyle. It is unfortunate I suppose, that sheep don’t get themselves ready to be eaten, and that we have to intervene, but that’s just the way it is.

From the field to the freezer is a process of a few days for a lamb. Once dead, it is skinned, gutted and hung for about three days before being cut up, ready to eat or to freeze. The job of getting it ready becomes gradually less unpleasant from beginning to end.

Butchering is pretty easy. By that stage the lamb has become meat, and it is simply a case of learning how to turn a whole carcass into roasts, chops, steaks and stew. Skinning and gutting are not nice jobs. They are messy, time-consuming and not for the weak-stomached. But it is the first part – the killing – which is the difficult bit.

For those who do it as a job, or who have done it every year for many years, I suppose it must become automatic and unquestioned. For me it is neither. And though, in reality, the death itself is quick and painless for the animal, it is a moment that lingers.

In some cultures, taking an animal’s life is an act of great spiritual importance, and many rituals have grown up around it, each marking the event as something significant. In Christianity too, saying grace and giving thanks must serve, in part, as a reminder that this food, this meat, is not to be taken for granted.

For me there is no ritual to be performed, and I would not go so far as to say that it is a spiritual event. But I do recognise something significant in it. And that recognition seems to be enough to satisfy any concerns, and, most importantly, to allow me to enjoy the food that it brings.

Tetris and sleep deprivation: how we can help emergency workers cope with trauma

First responders are at serious risk of developing PTSD during events like the Paris attacks. 

Some people seem able to deal with anything. They save a stranger from bleeding out in a bombed restaurant, protect passers-by from heavily armed gunmen, pull dead and dying people out of collapsed buildings, and they keep going because it is their job. These people are first responders.

When trauma goes on for days, as it has recently in Paris, however, the odds of them bouncing back from the violence, death and injury they are witnessing rapidly diminishes. They are at greater risk of developing a severe stress reaction known as post-traumatic stress disorder (PTSD). One study found that the worldwide rate of PTSD among first responders is 10 per cent, much higher than the 3.5 per cent rate among those not involved in rescue work.

Tetris to the rescue

So how best to address the problem? Research is in its infancy, but there are some promising studies. Emily Holmes’ group at the University of Cambridge has been looking at the benefits of playing Tetris, a video game, after a traumatic experience. The idea is that this could block the consolidation of traumatic memories so they don’t “flash back” later on.

For the study, her team first traumatised people by showing them distressing footage from public safety videos. The next day they invited them back into the lab to reactivate the memories with still images taken from the videos. One group then played Tetris for 12 minutes while the other sat quietly. Over the following week, the group who played Tetris had about 50 per cent fewer unwanted memories from the films compared to the group who didn’t.

The team concluded that playing Tetris helped individuals because it soaks up their visual processing capacity, making it harder for the brain to consolidate the visual parts of a traumatic memory.

Since it takes about six hours for the brain to cement a memory, the key is to play the game soon after trauma or within six hours of re-activating the traumatic memory. How long the helpful effects of playing Tetris will last and whether it will translate into helping people after real-life trauma is still unknown.

Talking it through

Other techniques, such as “updating”, taken from a highly-effective talking treatment for PTSD, may be more practical and easier to implement.

Like a detective, updating is a technique that focuses on finding new information and linking it to the case, the past memory. This is necessary because when the brain and body are in survival mode during trauma, the mind finds it difficult to encode all the relevant facts. Often key pieces of information that could make the memory less traumatic are lost. Updating links new information to someone’s memory of their trauma to make it less upsetting.

But can updating help to reduce unwanted memories after trauma?

We carried out a study, published in PLOS ONE, in which we traumatised people by showing them terrifying films of humans and animals in distress. We then divided our participants into three groups. One group watched the films again but were given new information about how long people suffered and whether or not they lived or died – essentially, they were updated. The second group watched the same films again but without the new information. And the third group watched films of humans and animals who were not in distress. The updated group had fewer traumatic memories and PTSD symptoms than the other two groups.

Updating is now being used by some UK emergency services. First responders will gather after critical incidents and update their memories of what happened before they go home.

Sleep deprivation

There are other techniques that may be helpful. One study found that depriving people of sleep may be useful in the aftermath of trauma.

But the same study found that a week after the trauma, people who had been deprived of sleep had the same number of unwanted memories as people who had slept well afterwards. Consequently, it remains unclear whether there would be any long-lasting benefits using this method. There are, however, certainly health risks linked to lack of sleep.

Still looking for a solution

To develop preventative interventions, we need to study newly-recruited emergency workers who haven’t yet suffered on-the-job trauma and follow them over time, spotting which “coping styles”, present before trauma, may predict their reactions afterwards.

For example, some people naturally react to stressful life events by dwelling on them, thinking about why they happened for hours on end. This strategy, called rumination, has been linked to PTSD in people who survived car crashes.

If rumination predicts PTSD in first responders, then preventative interventions could train people to spot when they are dwelling on an event and refocus their attention to the task at hand.

When we have identified which factors heighten emergency workers’ risk of developing PTSD, programmes can be developed to target those vulnerabilities. Only then can an intervention, directed at first responders most at risk of developing PTSD, properly protect them in their line of work.
