IS A VEGAN DIET HEALTHY?
By Mary Lynch
As a registered nutritionist, the question “Is the vegan diet healthy?” is one I get all the time, especially at this time of year.
Frustratingly, the answer is that it depends as much on what you eat as with any other diet. Someone living purely on ready salted crisps or chips, for example, would be technically following a vegan diet, but it would in no way be healthy.
However, research shows that there are potential benefits to a vegan diet. A recent study indicated that the average vegan diet is higher in vitamin C and fibre, and lower in saturated fat than one containing meat. In addition, statistics show that vegans have a lower BMI (height-to-weight ratio) than meat eaters – in other words, they are skinnier.
You see, a diet without any meat or dairy products is likely to contain a lot less saturated fat, which is related to increased cholesterol levels and increased risk of heart disease. We also know that fat contains more calories per gram than other foods, and so vegans may consume fewer calories as a result. Finally, a vegan diet is generally thought to contain more cereals, fruits, vegetables, nuts and seeds than a non¬vegan diet.
Sounds great right? Not quite. In terms of micronutrients, a vegan diet is actually more susceptible to being nutritionally poor. A vegan diet is naturally low in calcium, vitamin D, iron, vitamin B12, zinc and omega-3 fatty acids. Therefore, if you follow a vegan diet it is essential that you get enough of these nutrients through specific vegan food sources – and may even need to take additional supplements. We have many recipes suitable for vegans that can help, just check out our vegan section. In our features we also have this traditional hummus recipe, which contains tahini – a good source of calcium, zinc and iron, which are all micronutrients hard to get a hold of on a vegan diet.
So there you have it: going vegan does not necessarily mean you are going to be healthier. In fact, I think that much of the improvement in diets among vegans is a result of education rather than going meat free. In other words, if someone chooses to go vegan they are more likely to care about what they are eating and therefore are more likely to educate themselves on the types of foods they should and should not be eating.

The suffix –y in the words healthy (1st paragraph) and fatty (5th paragraph) gives the idea of:
The true potential of technology to change behavior
Technology could successfully change behaviours where decades of campaigns and legislation have failed. With the quantified self already walking among us and the internet of things within easy reach, digital technology is creating unprecedented opportunities to encourage, enable and empower more sustainable behaviours.
If we are to unlock the power of technology we must be more ambitious than simply digitising analogue strategies or creating another communications channel.
The true potential of technology lies in its ability to do things that nothing else can do. In behaviour change terms, the potential to succeed where decades of education programmes, awareness campaigns and product innovation have failed; to make a difference where government policy and legislation has had limited impact.
Using behavioural insights, it is possible to highlight the bottlenecks, drop out points and achilles heels of traditional behaviour change efforts — the reasons why we have failed in the past — and apply the unique possibilities of technology to these specific challenges.
Overcoming our limitations
Luckily, the history of the human race is almost defined by its ability to invent stuff that bolsters its feeble capabilities. That stuff is, of course, what we generically refer to as 'technology'. And in the same way that the internal combustion engine and the light bulb allow us to overcome our relatively feeble powers of motion and perception, so digital technology can be directed to overcoming our relatively feeble powers of reasoning, selfcontrol, motivation, self-awareness and agency—the factors that make behaviour change so difficult.
Herein lies the true potential of technology: not in the laboratory or the workshop, but in an understanding of the behavioural dynamics that define the human condition, both generally and within the context of a specific user-group, market segment or community.

THE NEXT ERA OF DRONES WILL BE DEFINED BY ‘SWARMS’
[ …]
Drones are becoming smaller, cheaper to make, can zoom around on their own, and gather in groups of hundreds, even thousands, to fly like a flock of birds. They’re called swarms – get enough of them together, and they could save your life, or they could be a deadly collaborative force on the battlefield.
[ …]
Plus there is no leader (1) or commander in a swarm; the swarm is a self-organising system in which allows drones to fly together without colliding. And only one operator (2) is needed to control the whole swarm.
Swarms are tough. One missile can bring down an aircraft, but a swarm can lose dozens of members and keep going. Air defences with a limited (3) supply (4) of missiles can be overwhelmed by enough opponents.
But drones will soon be swarming in many other situations too, from rock concerts to barnyards. In fact, you probably already have seen swarms of drones in everyday life. Chinese company eHang claimed the record for the biggest swarm, in a spectacular New Year show in which 1,000 drones formed a map of China and the Chinese character for 'blessings' (5).
Drone swarms may even have a place on the farm. They can spot plant disease and help manage water use, or spray pesticides and herbicides only in the exact spot needed, all working cooperatively to cover the area and fill in gaps.
So, what does the future hold for swarming (6) drones? Swarming drone technology is still very much in their infancy. But it’s evolving fast. In fact, they could one day live alongside us.

I started to run because I felt desperately unfit. But the biggest pay-off for me was – and still is – the deep relaxation that I achieve by taking exercise. It tires me out but I find that it does calm me down. When I started running seven years ago, I could manage only 400 meters before I had to stop. Breathless and aching, I walked the next quarter of a mile, alternating these two activities for a couple of kilometers.
When I started to jog I never dreamt of running in a marathon, but a few years later I realized that if I trained for it, the London Marathon, one of the biggest British sporting events, would be within my reach. My story shows that an unfit 39-year-old, as I was when I started running, who had taken no serious exercise for twenty years, can do the marathon – and that this is a sport in which women can beat men. But is it crazy to do it? Does it make sense to run in the expectation of becoming healthier?
My advice is: if you are under forty, healthy and feel well, you can begin as I did by jogging gently until you are out of breath, then walking, and alternating the two for about three kilometers. Build up the jogging in stages until you can do the whole distance comfortably.

By adding the prefix mis-, as in the word “misplaced” (line 07), a word changes to mean something.
