Stop throwing food in the trash: it’s killing the planet

For the sake of keeping the peace I had to bite my tongue. The meal had been a rare treat: succulent sirloin steak cooked medium-rare, smothered in a rich, creamy peppercorn sauce, served alongside bowls of al dente vegetables. But as the plates were piled up at the end of the meal, I watched aghast as I glimpsed a kitchen bin lid being flipped up and two thirds of an uneaten 10oz steak being scraped into the inky blackness of the bin liner. Not only had a week’s worth of sandwich fillings gone for good but a cloud of planet-warming gas would soon be billowing heavenwards when that lonely piece of cow flesh reached its journey’s end in landfill.

The grizzly details
Medical school training had taught me that nerves in the adult brain and spinal cord do not regenerate but are forever lost when damaged. Yet through many tears, I have already experienced that this wisdom does the human brain and body a great disservice. The bodies we have are far more incredible than we give them credit for:
5 Reasons Why we are Scared of Cooking with Spices
It’s been about a year since you last read one of my blog posts and I confess that book writing is a busy, all-consuming existence. This much-loved blog has been sadly dormant whilst I have chiselled away over a hot laptop in my writer’s cave. Throughout this blog wilderness, I have been key-tapping and kitchen experimenting for Book Number Two, which I am delighted to say is now available for purchase online and in all good book stores. Called ‘The Science of Spice’, I use science to explain how we can cook with the most misunderstood of culinary ingredients with confidence.
There is a world of science that explains why some dishes taste soooo good because of the spices they contain. Everyone knows that oregano in a pasta sauce, chilli in a fajita or a crack of pepper over a freshly seared steak will get the taste buds tingling. But what on earth do we do with that little-used jar of cumin powder?
Why are the curries we cook at home never as good as the ones served at our local restaurant?
And will you ever again need to use the packet of black cardamom seeds you once bought for a recipe three years ago?
I have been given the green light by the nice folks at publisher DK Books to reveal the innards of the book. So as a means of whetting your appetite, I offer you the top three reasons why I think so many cooks leave their spice jars gathering dust at the back of the kitchen cupboard… Read more
2017 wasn’t all bad: a good news story that will change the world forever
Now that the end is nigh for 2017, I think we’d all agree that the last twelve months have had more than their fair share of memorable moments. We’ve seen Donald Trump begin his reign of power, Kim Jong Un shoot off his shiny new intercontinental missiles, the Grenfell tower block burn down in the UK, and the bell ring for round one of the political bout that is Brexit. It’s hard to remain upbeat with a steady trickle of terrorist atrocities, a never-ending migrant crisis, and Middle East conflicts that show no sign of ending. There has, however, been a lot of good news that has slipped under the radar. This blog post is about my choice of what didn’t get the publicity it deserved. Not everyone will agree, and I’d be interested to know what other people would choose (feel free to comment below).
Get ready to say ‘bye bye’ to some very nasty diseases
The past year has witnessed some incredible advances developments that look set to revolutionise our lives for ever – and in a very good way. My pick of this year’s most important medical breakthroughs came in the form of a new type of medical treatment called gene therapy. 2017 has seen the coming of age of a new gene editing technology that has been the talk of science town. Called CRISPR (pronounced ‘crisper’), this is an innovation that lets lab workers precisely write to and edit a person’s genetic code. It’s getting so accurate that next-generation ‘CRISPR 2.0’ (which debuted in October) has made it possible to snip and chop just as you would correct a spelling mistake on a word processor.
With this emerging therapy, it is quite possible that conditions like haemophilia and sickle cell disease will go the way of smallpox and be eradicated from planet Earth. The source of the problem – the faulty DNA code – will be fixed with a bit of genetic jiggery-pokery. Back in March, a French teenager was apparently cured of sickle cell disease with a gene therapy. It was causing him agonising ‘sickle cell crises’ in his limbs and abdomen, each bout lasting up to a week. His internal organs were also slowly failing. Now the 14-year-old boy has been “given his life back” – the genetic error he was born with has been erased.
In November, gene therapy was used for the first time in a 44-year-old man afflicted with Hunter’s Syndrome – a hereditary condition causing stunted growth, low IQ, and progressive disability. And just last week the USA drug approval authority (the FDA) gave the all-clear for gene therapy to treat a rare form of blindness. The countdown has now begun until we create ‘cures’ for the evilest of degenerative diseases, like Huntingdon’s disease and Motor Neurone disease.
It doesn’t stop with the hereditary conditions that you are born with. Researchers have realised that Type 1 Diabetes could also be consigned to the history books with these advances – they have been devised a way to genetically program the liver to produce the insulin that the body lacks. For people with diabetes, this should mean no more daily injections and finger-prick sugar tests.
CRISPR also means that we we have a serious chance of healing many types of cancer – or at least keeping them at bay better than ever before. A fantastical new cancer treatment, called CAR-T therapy, sees doctors taking a big slug of a person’s blood, extracting a sample of their immune cells, then genetically programming them to attack their cancer. These super-powered infection-fighters are injected back into the blood so that they set about killing the cancer as if it were a virus. A few days ago, research results showed that it worked against lymphoma (a cancer of the blood) and right now it is being piloted in brain tumours and a host of other cancers.
As exciting as they are, none of these advances have the shock and awe of a Harvey Weinstein sex scandal, so don’t sell papers or get the clicks. Neither do they usually arrive in ‘Eureka!’ apple-dropping breakthrough moments, but from the slow drip-drip-drip of steady progress from countless researchers chipping away at the rockface. It’s going to take patience –many years – until the investment pays out. But these good news stories will probably go on to effect all of our lives, and is certainly a far better bet than any bitcoin.

Science of Cooking: Why do bananas go brown in the fridge?
To celebrate the launch of my recent book, The Science of Cooking: Every question answered to give you the edge, published by DK Books, I am starting a special series of posts about food science. The book answers 160 commonly asked cooking questions, busts lots of culinary myths (no, don’t throw away the mussels that haven’t opened), and gives you lots of how-to and hands-on guides for shopping and cooking impressive dishes without pricey equipment.
Not wanting to spoil any of the surprises within the book itself, consider this series of titbits a something of a hour derves… Read more
Fatigue: the problem most people don’t understand
If you’ve never experienced extreme fatigue, then it’s difficult to appreciate. It’s all too easy to say that someone is “lazy” if they complain of no energy or go for a lie down at two in the afternoon. For a long time, many doctors haven’t understood it. For people who are constantly exhausted, us doctors would scrawled ‘TATT’ in the medical notes when someone said they were ‘tired all the time’. They are letters I had often scribbled, but until I felt real fatigue after brain tumour surgery nine years ago, I didn’t truly understand it. Read more
Grub’s up! Why we should all start eating insects
Once upon a time, vegetarians were seen as weirdos who had to make do with a cheese omelette when dining out. Today, non-meat eaters get some of the tastiest options. There is no shortage of meat substitutes foods to sink our laughing tackle into, like Quorn, ‘soy mince’ and tofu. But there is a newcomer crawling onto that non-animal list is heralded as the ‘next protein’. It is apparently going to feed the world, help undo climate change and make us slimmer and healthier into the bargain. The only fly in the ointment? This wonder food is insects. Read more
The vaccine controversy that isn’t controversial
Polio is a disease that should be long dead by now. Some readers will be old enough to remember rooms full of ‘iron lungs’ – grotesque life-support machines that did the breathing for children left paralysed by this deadly infection. With their small heads poking out through a tight rubber seal, steam engine-like contraptions sucked and pressed on the child’s chest in the hope that their strength would recover. Polio infection was also called ‘infantile paralysis’ and it struck terror into the hearts of parents everywhere. The viral disease starts out like a mild flu then attacks the brain and spinal cord. A blight on humankind, children who survived could be left with monstrous deformities. Read more
The Science of the Midlife Crisis – a modern myth?
They say that life begins at 40. If that is true, then I have four and half years coddled up in the womb of young adulthood before I am birthed into the cold harshness of ‘middle age’. We tend not to think too much of being ‘middle aged’, and we all know someone who has gone through (or is going through) the dreaded ‘midlife crisis’. About a quarter of adults aged over 40 say that they have had such an episode and the story usually goes something like: a 40- or 50-something man splashes his lifesavings on a flashy sportscar or noisy motorbike, starts a rock band, and/or quits his job to swan off with a younger woman. What on Earth could possibly possess a responsible grownup show such sudden reckless abandon? Read more
