Gene editing could revolutionise agriculture, with some scientists promising healthier and more productive crops and animals, but will consumers want to eat them? With the first gene edited crops recently approved for sale, Emily Thomas hears why this technology might be quicker, cheaper and more accurate than the older genetic engineering techniques that produced GMOs, and asks whether these differences could make it more acceptable to a deeply sceptical, even fearful public.Some are not convinced by the claims, and there are concerns that current regulations won't protect consumers or the environment from any potential risks. By putting their faith in technology, have scientists and companies overlooked other simpler solutions to our food security problems?Producer: Simon TulettIf you would like to get in touch with the show please email thefoodchain@bbc.co.uk(Picture: A DNA model on a plate.

In an illustrious career spanning three decades, there’s little that booking-writing, seed-breading, ‘philosopher chef’ Dan Barber has not put his hands to. Celebrated as the poster child of the ‘farm to fork’ movement, he tells Graihagh Jackson how a visit to a wheat farm called into question everything he thought he knew about agriculture and changed his cooking and ethos forever. Surprisingly though, Dan started life wanting to be a writer not a chef. Through five dishes, we hear how a failed stint as a baker, a baptism of fire in french kitchens and running a company from a mice-infested kitchen eventually won him over to the cause. We learn that an obsession with simplicity and flavour has taken him on a farming odyssey around the world, what coronavirus can teach us about the future of food, and how it all started with a humble dish of scrambled eggs.If you would like to get in touch please email thefoodchain@bbc.co.uk(Picture: Chef Dan Barber.

Three people who lost their vision as adults tell Emily Thomas how they learnt to cook again, becoming so accomplished in the kitchen that they became restaurateurs, cookbook writers, food podcast makers and Masterchef winners. They explain how their relationships with food have changed, and why cooking with just four senses can make you a better chef. (Picture: Payal Kapoor, Simon Mahoney, Christine Hà.

Millions of Americans live in so-called ‘food deserts’ - areas where it’s hard to access fresh affordable food. For people who aren’t able to travel to other neighbourhoods to do their food shopping, this might mean microwave meals bought from the local gas station are the only way to feed themselves. Emily Thomas meets two people who live in areas where fresh food is hard to come by in Albany, NY State and St Louis, Missouri. They explain why they reject the term food desert in favour of ‘food apartheid’ - which they say addresses the food system in its entirety, including race.(Picture: two shopping trollies with food, credit: Getty/BBC)If you would like to get in touch with the show please email thefoodchain@bbc.co.ukContributors: Tyrean Lewis, Founder and CEO of Heru Urban Farming Roni Minter

Carlo Petrini is leading a food revolution - one that fights to protect local, traditional ingredients and farming methods in the face of a standardised, industrialised food system. From a protest against a McDonald's in the heart of Rome, to a network of more than 100,000 members in 160 countries, his Slow Food movement strives for a world where producers are fairly treated and the planet is better protected.Carlo tells Emily Thomas the story of his life and activism and why he believes that a post-pandemic world offers a profound opportunity for economic, environmental and social change - should we choose to take it.Producer: Simon TulettIf you would like to get in touch with the show please email thefoodchain@bbc.co.uk(Picture: Carlo Petrini.

Chillies can be hard to love at first, but they are integral to the cuisines of many countries. So what do you do if hot peppers are at the heart of your food culture, but your child can’t stand the heat?Emily Thomas is joined by three cooks and parents. Each of them grew up in a food culture where chillies are important, but are now bringing up their own children in a country where hot peppers have less significance. We hear why you might want a child to develop a taste for chilli, how young they should be introduced to it, and whether you should ever resort to bribery.Guests: MiMi Aye, Sunrita Dutta, Mei Li.

Serving sizes have increased dramatically in recent decades. It’s happened so subtly that many of us simply don't realise, but it’s having a serious impact on our health and our planet. So, how can we reverse it?Emily Thomas learns how food manufacturers and clever marketers have nudged us into buying ever larger portions, leveraging ultra cheap ingredients and our own psychology. We hear that the phenomenon is so pervasive it’s also crept into the home, where many of us have lost any concept of what an appropriate portion is.Given the increasing awareness of the poor health and environmental outcomes linked to overconsumption, we find out what regulators and companies are doing to shrink portions back to a more sustainable size, and ask whether the real answer might lie in a fundamental shift in the way we all value food.Producer: Simon TulettIf you would like to get in touch with the show please email thefoodchain@bbc.co.uk(Picture: A woman drinking from a giant coffee cup.

Anti-Asian hate has surged since the coronavirus outbreak, and some of the most common targets have been Chinese food businesses.Tamasin Ford speaks to three people who’ve witnessed the rise of Sinophobia first hand and seen it damage not only their livelihoods, but also their families.They explain why they’re not prepared to stay silent, as was often the case for previous generations, and how they plan to use food in the fight against racism and ignorance.Producers: Simon Tulett and Sarah StolarzIf you would like to get in touch with the show please email thefoodchain@bbc.co.uk(Picture: A person holds a sign during a rally against anti-Asian hate in Minneapolis, Minnesota.

President Biden has pledged to scrap the 'tipped wage' in the US - a salary system where diners effectively subsidise waiters' wages.It's a move that's divided restaurant staff across the country. Tamasin Ford hears from those who want a higher minimum wage and an end to a system they argue makes servers vulnerable to discrimination and harassment. On the other hand, some staff are outraged because, they say, the changes could wipe out their chance to make double or even triple their hourly wage in tips.With the coronavirus pandemic wreaking havoc on the hospitality industry, restaurant owners too are wondering whether now is the time for a shake-up, and also how customers might react.If you would like to get in touch with the show please email thefoodchain@bbc.co.uk(Picture: A waitress writes notes on a pad.

On the streets of Bucharest a woman unwraps a package of Chinese pepper ... and falls in love. In Portland Oregon, a family finds a new home - in a farmers market. A food writer opens her front door in London and finds a Chinese banquet waiting for her. On a cold winter’s morning, in a city 10,000 kilometres away from her family, a woman stands and waits for a taste of home. As part of the BBC World Service festival exploring how the Coronavirus pandemic is reshaping our social lives, Emily Thomas hears four stories of how food can bring us closer together when we’ve never been more distant from one another.
