Jamie Oliver’s cooking courses give diets a boost latest study finds
Jamie Oliver’s back-to-basics approach to improving our diets really does work, according to a new study ‘Evaluation of the effectiveness of the Ministry of Food cooking programme on self-reported food consumption and confidence with cooking‘ published in Public Health Nutrition.
Researchers at the University of Leeds found that men and women who attended one of the celebrity chef’s eight-week Ministry of Food courses showed significant improvements in their eating habits.
The participants greatly increased their intake of fruit and vegetables, halved the amount of snacks they ate and became much more confident about their cooking skills, the nutritionists found.
‘These positive changes emerged immediately following the course and had increased further by six months after the course,’ said researcher Janet Cade, Professor of Nutritional Epidemiology at the University’s School of Food Science and Nutrition.‘This suggests that the MoF programme may encourage short-term changes in dietary behaviour which can be maintained and improve over longer periods of time.’
Mr Oliver launched his MoF courses in 2008, stating that he wanted to inspire the nation to prepare tasty, nutritious food, whatever their budget, and described the initiative as the most important campaign he had ever worked on. There are now four standalone MoF centres in the UK, in addition to outreach courses in the community, as well as allied projects in Australia and the U.S.
For the University of Leeds study, which was published in the journal Public Health Nutrition, the researchers surveyed almost 800 people who took part in MoF courses held in Leeds, West Yorkshire, between 2010 and 2014. They found that the number of fruit and vegetable portions eaten by the participants increased from 2.7 before the programme to 3.4 immediately afterwards.
When 500 of the participants were surveyed six months later, the average number of fruit and vegetable portions eaten daily had increased even further, to 4.1. The amount of snacks eaten per day dropped from two before the course to 1.7 immediately afterwards. Six months later this had dropped to 1.1.
The participants also reported significant gains in their levels of cooking confidence, rising from a score of 2.7 on the scale (where 0 was marked as not at all confident and 5 very confident) before the course, to 4.1 immediately afterwards and 4.4 six months later.
‘When we analysed the results by sex we found that men – who previous studies have shown tend to have less confidence in cooking than women – actually reported a greater growth in confidence than the women who took part,’ said Prof Cade.
Jamie Oliver said: ‘Ministry of Food, for me, has always been about empowering people and giving them the knowledge and the confidence to feed themselves and their families better.
‘The beauty of it is that it’s all about local people helping other local people to create delicious, fresh, nutritious food that doesn’t cost a fortune.
‘This important study shows beyond doubt that teaching people to cook really works and really does make a huge difference. If only more towns and cities had Ministry of Food Centres.’
Professor Cade added: ‘In the UK there has been a decline in cooking skills since the 1950s. Home-made meals have been replaced with ready meals and convenience foods.
‘This lack of cooking ability coupled with ready access to high energy convenience foods has contributed to an increase in the number of people who are now overweight.
‘Our study shows that if you help people improve their cooking skills, and their confidence in these skills, then they will make healthier food choices.’

The MoF centre was established in Leeds in 2010. It is a fully fitted domestic kitchen fitted within a stall in Leeds Kirkgate Market.
The food centre offers cooking courses which are open to all, but have the aim of teaching those with no or limited cooking skills how to prepare tasty, healthy meals on a budget.
Participants attended the centre once a week, over eight weeks for 90 minutes per session, to learn a range of cooking skills and a variety of recipes which taught them progressive cooking skills that they could then use to cook a range of meals for themselves and their families.
They paid between £4.50 – £7.50 per session, based on their individual circumstances, with students and those on means-tested benefits paying the reduced rate. The project was also supported by Leeds City Council’s Public Health Team.
Each cooking session promoted a key healthy eating message to educate services users on a wide range of healthy eating messages, from understanding food labels, to reducing salt, fat and sugar.
Specific attention was given within the course to highlight the importance of The Eatwell Guide developed by the Department of Health, stressing the importance of staple food items and portion control to achieve dietary balance.
A total of 795 participants completed the surveys before the course and immediately after.
A total of 462 completed an additional survey six months later.
