The Food Chain

The World Health Organisation says close to 60 million people are living with dementia; and there are 10 million new cases every year. But could what we eat help to prevent it?

Three guests who've been exploring the potential for diet to help prevent dementia tell Ruth Alexander about their findings. We hear from Professor Christy Tangney of Rush University System for Health in the United States – she co-created the MIND diet; Anne-Marie Minihane, Professor of Nutrition and Genetics or Nutrigenetics as it’s known, at Norwich Medical School at the University of East Anglia in the UK; and Dr Lizette Kuhn, a dietitian in Pretoria, South Africa.

Dementia is a syndrome associated with a decline of brain function that can affect memory, thought processes and behaviour. In some cases this can impact people’s ability to shop, cook and eat a meal. The most common form of dementia is Alzheimer’s Disease.

In this programme Ruth Alexander meets people living with dementia and their families, to hear about the ways in which a diagnosis can impact mealtimes.

Ruth meets Alan and Amy Lambert in Manchester, England. Alan was diagnosed with Alzheimer’s Disease in 2024 and his daughter Amy lives with him. They share some of the techniques they’ve developed at home to support Alan.

For Ruby Qureshi in Canada, cooking was a huge part of her life before being diagnosed with Alzheimer’s in 2020. Ruth hears how her husband Pasha Qureshi has joined her in the kitchen in a supporting role.

Jo Bonser in Nottingham, UK shares her experiences of supporting her mother who lived with vascular dementia and in 2016 stopped eating and drinking. Jo has gone on to set up a company, Dignified Dining that offers training in this area.

And Aideen McGuinness is a registered dietitian working in the Memory Assessment and Support Service in Country Wexford Ireland, and co-author of a guide on dementia and nutrition.

Something as simple as sharing a meal or utensils can carry social stigma for the millions born into the bottom of India’s caste system, a social structure that divides people into different groups.

In this programme Devina Gupta explores the foods of the Dalit community, historically considered at the very bottom of the caste system. She hears how many dishes evolved from necessity, due to low incomes and lack of available food and speaks to people looking to record and share these dishes with future generations.

Devina meets people who identify as Dalit to talk about the discrimination they have experienced in their communities and workplaces as a result of their family’s social status, and how it can be particularly hard to find work in the food industry.

What’s at stake when a child has their first meal in a new home?

For children entering care, especially those who have faced food insecurity, that first plate of food can be a big moment.

In this programme, Ruth Alexander explores how food and mealtimes can help children feel safe and give them a sense of belonging.

She meets Jessica-Rae Williamson, a 21 year old care leaver from Manchester, England, who still remembers the first meal she ate with her foster family, aged 13.

In Wrexham, Wales, Ruth meets long-term foster carers John and Viv, Cath and Neil and Rosemary, who have opened their homes to dozens of children through Foster Wales. They discuss their strategies for dealing with picky eating and hoarding.

Dr Katja Rowell, feeding expert and author of the book “Love Me, Feed Me: The Foster and Adoptive Parent’s Guide to Responsive Feeding”, gives her counter-intuitive tips for avoiding mealtimes becoming a battleground.

And Melissa Guida-Richards, author of the book “What White Parents Should Know About Transracial Adoption”, shares her experience of being adopted from Colombia by Italian and Portuguese parents living in the US and her subsequent search for her Colombian heritage through food.

This programme contains discussion of food poverty and insecurity, and disordered eating. If you’ve been affected by any of the issues raised and need support, speak to a health professional.

Protein is a health and fitness buzzword – plastered on packaging, prioritised in diets and praised by fitness influencers.
