How do you feed a dog? The answer may be more fraught than you had imagined. Should you give them ‘dog food’? Is it a step too far to feed them at the table? And can man’s best friend thrive on a vegetarian diet? we bring together three dog-loving experts from the UK, India and the USA to analyse what dog feeding reveals about our relationship with animals and even our own relationship with food. Be prepared to hear some surprises, some empowering advice and maybe some uncomfortable home truths. And even if you don’t have a dog, you may get some ideas that you can apply to your own life.

A lack of sleep might leave us tired, but it can also have a major impact on what we eat, and our health. Ruth Alexander explores the surprising relationship between diet and a poor night’s rest, and learns that it’s not just what we’re eating, but when: we hear about the perils of consuming calories late into the evening or, even worse, overnight. But it’s not all bad news: there’s growing research into the idea that we might be able to improve our sleep quality by tweaking our diets.

Caffeine is a key ingredient in some of our favourite foods and drinks, but it’s also a mind-altering drug that can be very tricky to quit. Tamasin Ford meets three people who’ve tried to cut caffeine out of their lives by eliminating some of its main sources from their diets - coffee, tea and chocolate. We hear about some uncomfortable withdrawal symptoms, social awkwardness, and the struggle to adapt to life without a caffeine high. How long did they stay caffeine-free?

In this final episode of 2021, we're revisiting some of the most powerful food stories from the pandemic. Following widespread restaurant closures and labour shortages across the hospitality sector, we catch up with a New York chef who is forging a new path. And what about those people who thanks to Covid-19 can’t even smell or taste their food anymore? We’ll be finding out whether this leading symptom of the virus is now better understood. Plus, how is one of the world’s newest emojis – the arepa flatbread - faring, one year on? (Picture: Drawing of sweet being unwrapped.

World War Two rationing imposed severe restrictions on food, so why would anyone voluntarily go back to it? Ruth Alexander meets three women who chose to adopt the diet endured in 1940s and 1950s Britain, one of them for an entire year. We hear how such scarcity inspired creativity, a reverence for the ingenuity of wartime cooks, and an enduring change of perspective on the responsibility of the 21st century food consumer.
