Caroline Walker

Caroline Walker (12 June 1950 – 22 September 1988) was a British nutritionist, writer, author and campaigner for better food, who died from cancer aged 38. After her death, the Caroline Walker Trust was established with a mission to "improve public health by means of good food".

At the 2019 annual Evening of Celebration for Walker and of the trust held at the Royal Society of Medicine in London, speaker Felicity Lawrence of The Guardian, a friend and colleague of Walker, said "She was the lodestar for campaigning around food and social justice that has guided me, and influenced countless others, ever since… She had a unique combination of erudition and academic ability with human warmth, and a gift for popular communication. She was a great phrase-maker, and a witty story-teller… She could simplify to communicate because she had such deep understanding of the science behind her subject. That was rare. And precious".

Early life and education Caroline Walker was born in Liss, Hampshire and educated at Cheltenham Ladies College. In 1972, she graduated with a BSc degree in biology from Queen Elizabeth College (now part of King's College, London) and then did a postgraduate degree in human nutrition at the London School of Hygiene and Tropical Medicine, where her supervisor was John Waterlow. Her MSc thesis, completed in 1978, rated first class with a distinction, was on the relationship between poverty, food and health.

Early career In 1968–69, for a year after she left school, she was a teacher at the Convent of Nazareth, Haifa, Israel, living with Arab families. In 1973–75 she worked as an editor at Elsevier Scientific Publishing in Amsterdam. In the period immediately before and during the 1973 October War she went back to Israel and became committed to the Palestinian cause.

Back in Britain as from the mid-1970s her commitment became and remained focused on the politics of food, as she associated with the Agricapital group, which examined food production and health, for example producing a critique of the UK bread industry, alongside the Politics of Health Group. Both groups researched and debated the science and politics of food, nutrition, health, production and consumption. They were shaped by the British Society for Social Responsibility in Science (BSSRS), set up in the late 1960s by distinguished scientists. BSSRS was based, as was Friends of the Earth (FoE), in Joseph Rowntree Foundation funded offices at 9 Poland Street, near Soho, London. She maintained links with BSSRS and FoE friends and colleagues for the rest of her life. Thus, she became a board member of the London Food Commission (LFC), a think-tank on food, health, society and economy created by the Greater London Council (1984–90), on which she remained until her death. A number of people from Agricapital and the Politics of Health Group were on the 15 person staff of the LFC or its 50-person board, such as Eric Brunner, Michael Joffé, Tim Lang, Tim Lobstein, and Aubrey Sheiham.

From 1978 to 1980, she worked at the Medical Research Council (MRC) Epidemiology Unit in Cardiff, working to Peter Elwood, then in 1981–1982 moved to the Dunn Clinical Nutrition Centre in Cambridge, working to Philip James. Her work at the Dunn Centre included a field study designed to see whether high blood pressure was linked with high salt consumption, for which she experimented on herself, adding sodium chloride and lithium to her diet. She then made a critical review of the state of the scientific literature on diet and major chronic diseases in Europe, starting with heart disease. She corresponded directly with researchers in 26 countries.

From 1983 to 1985 she worked as a community nutritionist for City and Hackney Health Authority, working to Ken Grant, in charge of the heart and stroke prevention programme. "The national diet" and "The new British diet". She became a pithy and pointed broadcaster, author and journalist, publicising the effects of good diet on well-being and good health, and poor diet on disagreeable, debilitating and deadly conditions and diseases. She was a regular contributor to BBC Radio 4's The Food Programme. Presenter Derek Cooper recalled in 1995 ‘She cried out against the debasement of our diet with such wit that even her victims must have thought she was rather wonderful’.

The Food Scandal In 1984, Walker co-authored with Geoffrey Cannon, who would later become her husband, The Food Scandal: What's Wrong with the British Diet and How to Put it Right. With special support from publisher Gail Rebuck it became a UK number one bestselling book. It contradicted the Department of Health's official 1981 statement that "Nutrition in Britain is generally good". The background to the book was the official NACNE (National Advisory Committee on Nutrition Education) report on the British diet, of which Philip James was convenor and chief author. NACNE was a committee of physicians and nutrition scientists commissioned by the British government to produce a report on food and health in the UK. Walker was the committee's honorary Secretary. The report was delayed and widely believed to have been suppressed for two and a half years, after lobbying from the food manufacturing industry and its representative organisations. Walker was incensed: ‘The less well off, the less well informed, the disadvantaged, would continue in ignorance to depend on diets which could eventually destroy their health. When the report finally appeared, its message was that the British would be much healthier if their diet contained less fat and sugar. and the prevalence of mechanically recovered meat in the British food supply.

In June 1984 Walker and Cannon and the publisher were sued by Beechams for a mistaken statement in The Food Scandal that its product Bovril paste contained sugar (the type of caramel included to give a meaty colour, is not a form of sugar) and Beechams won an injunction in London's High Court. The book was withdrawn, reprinted and republished. An expanded and updated paperback edition was published in 1985.

Later career In his biography The Good Fight. The Life and Work of Caroline Walker, Felicity Lawrence wrote in The Daily Telegraph, for which Caroline was a columnist: “She was… a scientist who was able to convey complex information in layman’s terms and with great wit”. Philip James, then of the Rowett Research Centre, Aberdeen, wrote in The Guardian: “Where will we find a successor to this young, engaging, warm and immensely effective campaigner?”.

The distinguished nutrition scientist Hugh Sinclair gave the address at Caroline's memorial service, and said "We cannot replace Caroline’s contribution to nutrition. But so many of us will always treasure the privilege of having known her and admire her immensely brave struggle against adversity". In her presentation at the trust's 2019 Evening of Celebration, Felicity Lawrence said: “Caroline would be thrilled to see this room full of young people working in the public interest, carrying on the good fight that she began”.
