Why do we enjoy foods that crunch? Listener Sheila Harris contacted The Food Chain with that question and asked us to find out if the food texture has any benefits. Ruth Alexander speaks to Danielle Reed, Chief Science Officer at the Monell Chemical Senses Center in Philadelphia, US, who says that crunchy foods signal freshness and help our brains decide if a food is safe to eat. Paediatric dentist Ashley Lerman in New York, US says crunchy fruit and vegetables can act as a natural tooth cleaner. Anthropologist Professor Noreen von Cramon-Taubadel at the University at Buffalo in New York, US says that the texture of our diets can impact the shape of our faces. Her work has studied how jaw shape has changed as humans switched from hunter gatherer to farming diets. Ciarán Forde, Professor of Sensory Science and Eating Behaviour at Wageningen University in the Netherlands explains how crunchy and other hard textures could help us to eat more slowly and consume fewer calories. And could crunch make foods more palatable? Chef Dulsie Fadzai Mudekwa in Zimbabwe says the texture is key to convincing people to try edible insects.

Is anyone following dietary guidelines?
Around 100 countries have official dietary guidelines, and more are on their way. But who is following them? Ruth Alexander asks how realistic healthy-eating advice is as she explores how official recommendations are developed, what they’re trying to achieve, and the obstacles standing in our way. We hear from Fatima Hachem, Senior Nutrition Officer at the United Nation’s Food and Agriculture Organisation, about how her team offers support to countries designing dietary guidelines.Chiza Kunwenda, senior lecturer in the Department of Food Science and Nutrition at the University of Zambia, tells us how he and a team of others drew up the latest dietary guidelines for Zambia and other countries in Africa.In Argentina, as well as advice, the government has issued black octagonal warning labels on foods high in salt sugar, saturated fats and calories. Are people taking notice? And can people around the world afford to eat according to guidelines? Dr Anna Herforth co-directed the Food prices for Nutrition project at Tufts University in the United States, tells us what she found. We also hear from shoppers at a community food outlet in the North West of England, about how cost is barrier to healthy eating.(Image: a plate of food showing suggested dietary guidelines.

Should we eat less rice?
Rice is the main staple for over half the world’s population. The crop has problems though – it is vulnerable to climate change, whether that’s drought or flooding. It’s also a crop that contributes to climate change, as it uses more water than other grain crops and is frequently grown in flooded conditions. Rice production is also a big source of methane emissions. In this programme Ruth Alexander hears about the possible solutions to these problems. Dr Yvonne Pinto, Director General of the International Rice Research Institute in the Philippines talks about their work developing new varieties of rice, and new more sustainable farming techniques. One rice company trialling these techniques is Tilda in the UK. General Manager Jean-Philippe Laborde explains what difference it’s made to water and fertiliser use as well as methane emissions. Given the problems with rice, should we just eat less of it? Jakob Klein, anthropologist at SOAS University of London explains the Chinese government’s attempts to convince people to eat more potato as a staple food. And we talk about the cultural importance of rice with listeners in the Philippines and Bangladesh. If you’d like to contact the programme email [email protected] Presented by Ruth Alexander.

What's the point of cookbooks?
When there are so many recipes available for free online, why does anyone still buy cookbooks? In this programme we look into the business of selling cookbooks, what future the format may have and hear about the treasured tomes you turn to time and time again. Ruth Alexander visits Books for Cooks, a specialist cookbook shop in London, to chat to Eric Treuille who cooks lunch for his customers from a different cookbook each day. She speaks to cookbook writers Mogau Seshoene in South Africa, author of ‘The Lazy Makoti’ books, and Joanne Molinaro in the US, author of ‘The Korean Vegan’. Doris Cooper tells Ruth what a publisher is looking for in a cookbook. She tells Ruth about her big hits and misses as editor-in-chief of Simon Element, a division of Simon and Schuster in New York. And listeners in Italy, Malta and the US tell us about their favourite cookbooks. If you would like to contact the programme email [email protected]. Presented by Ruth Alexander.

Has Christmas food gone mad?
Prosecco flavoured crisps? Eggnog chicken? Sticky toffee pudding trifle? The innovation for novelty Christmas products seems endless, but is there the appetite? Ruth Alexander lifts the lid on an industry churning out festive food hits, and flops, in the race for Christmas tastebuds. She visits the Good Housekeeping Institute in London to take part in an opulent dessert testing event, deciding which puddings are the best on the shelves this year. Eric Nummelin and Mike Vahabi from Hela Spice in Toronto, Canada, reveal the wacky inventions they have come up with for this year, and how inspiration can strike at any time. A former buyer for a large European supermarket chain talks about how to “win” Christmas with headline-grabbing products, and what happens when shoppers try things once and don’t go back for more.
