Lunch is up for London school kids. What are the implications of the universal free school meals policy in London?

As well as providing vital relief to disadvantaged children and families, free school meals are essential to ensuring children reach their full potential, writes Dr Jennie Parnham from the School of Public Health.


On 19th February 2023, the Mayor of London, Sadiq Kahn, announced plans to provide free school meals to all primary schoolchildren (ages 4-11 years) in London.

In England only infant schoolchildren (4-7 years) are given universal free school meals (UFSM). For older children, free school meals are means-tested and are only available to households receiving Universal Credit (with incomes <£7,400/year). The remaining children must pay for school meals.

This policy will dramatically expand the current free school meal provision in London, reaching 270,000 children at a cost of £130 million. But what will this unprecedented policy announcement mean for children, their families, and our wider society?

Dr Alejandra Tomas, Senior Lecturer at the Department of Metabolism, Digestion and Reproduction, explores new and emerging incretin-based therapies for managing diabetes.

Diabetes is a disease that has reached epidemic proportions, with millions of people dying or suffering from a myriad of associated complications. Given that cases are projected to increase worldwide over the coming decades – especially in low- and middle-income countries – there is an urgent need to develop and deploy effective treatments for the disease.

Food for thought: Experiences from Imperial’s Food Student Research Network Conference

Dr Aaron M. Lett, Director of the Food Student Research Network, providing a plenary talk and officially launching the Food Student Research Network.

Recognising the value of interdisciplinary learning, Imperial’s Food Student Research Network aims to bring together students from across the College’s faculties to enable the cross-fertilisation of ideas and research in fields relevant to food. Here, members reflect on the Network’s inaugural conference.

In September, Imperial’s Food Student Research Network hosted its first Annual Conference. Reflective of the ethos of the network, this conference was an event for students, led by students.

What is being done to help low-income children get a Healthy Start? And is it enough?

Jennie Parnham shares insights into an evaluation of Healthy Start, a food assistance policy in England.


Low-income children have a much lower chance of eating a healthy diet than more affluent children, as highlighted by the recent campaigning of Marcus Rashford.

The causes of this disparity are very complex. It’s also important to say that although it’s more likely, it’s not deterministic. Many children of all backgrounds have a healthy diet. However, unfortunately factors tend to cluster together, making a healthy diet less likely for some. Let’s consider a single parent with a young child. One-third of children in single parent households live in poverty and it can cost up to 75% of their disposable income to buy the recommended food for a healthy diet. This is because healthy food is three times more expensive than less healthy foods. In their neighbourhood, there might be more places to buy ultra-processed fast food than healthy food. Finally, they may have less time to prepare healthy food, as there are fewer helping hands at home. In this environment, many families find their options for healthy eating limited. (more…)

Three Imperial postgraduate research students recount their experiences of hosting the Nutrition Futures Conference 2021 in collaboration with The Nutrition Society.


In September 2021, Imperial’s Section of Nutrition Research hosted the Nutrition Futures Conference 2021 in collaboration with The Nutrition Society at the Cavendish Conference Centre, Marylebone.

The Nutrition Society is one of the largest learned societies for nutrition in the world. In late 2019, Dr Aaron Lett led the bid to bring this student-focused conference of the Nutrition Society’s conference calendar to Imperial College London. This was the first conference the Section of Nutrition Research at Imperial has hosted and provided the perfect opportunity for Imperial to share its expertise in nutrition-related research and strong ethos and enthusiasm for student development to undergraduate and postgraduate nutrition students across the world.

A public health Insight into the UK’s new obesity strategy

Public health researcher Charan Gill provides an inside look at the Government’s new obesity strategy and discusses if it’s the way to tackle the obesity crisis.


In July the UK government released the ‘Tackling Obesity: empowering adults and children to live healthier lives strategy’. As a public health researcher, I was eagerly waiting for this to be published and I know many others were also anticipating what was going to be released in the document.  This new strategy has received a great deal of criticism, and although it does raise valid and important points, it has left many confused. Despite this, there have also been several important issues raised which needed to be addressed. Over recent years, several obesity strategies have been published, but I want to highlight some key positives from this strategy and how I see it working.

Firstly, I want to recognise how great it is to see the government emphasising on public health and prevention. Acknowledging that there are public health services that can offer huge benefits to the public and will in turn have beneficial impacts and reduced strain on the NHS. The strategy claims that the government will expand weight management services and the NHS Diabetes Prevention Programme which are a few services which can offer preventative support.  These suggestions are fantastic and offer practical resources to support individuals who want to make healthy lifestyle changes.

Is mycoprotein an ideal food for managing blood sugar levels in Type 2 Diabetes?

For Diabetes Awareness Week, Anna Cherta-Murillo explains how mycoprotein, a food made of fungus, may hold the promise for managing blood sugar levels in Type 2 Diabetes.


If I were to ask you the first thing that comes to mind when you think of fungi, you would probably say mouldy walls, gone-off food, or athlete’s foot. The Fungi kingdom is often not viewed in a positive light. However, we owe a lot to fungi; they produce life-saving antibiotics, have allowed organ transplantations in humans and can recycle many types of waste. In the area of nutrition, some fungi also have the potential to affect human health in a beneficial way, although little research has been devoted to it compared to other foods. In the Nutrition Section of the Department of Medicine at Imperial, we are putting fungi into the limelight and studying the impact of a particular type of fungus on blood sugar levels and appetite in South Asian and European people with Type 2 Diabetes (T2D).

The problem

1 out of 20 people worldwide has T2D, with South Asians being more prone to the disease compared to Europeans (Figure 1). People with T2D have higher blood sugar levels than normal, which over time can increase the chances of developing long-term complications such as blindness, kidney disease and heart failure. It is therefore important to manage blood sugar levels in people with T2D in order to keep blood sugar in the normal range. The first-line strategy to achieve this is by improving dietary intake. Healthy, balanced diets are generally characterised as being high in dietary fibre and protein, which decrease both blood sugar levels and appetite. If blood sugar levels are reduced toward normal levels, the chances of having T2D-related complications are reduced. Likewise, if appetite is decreased, intake of energy-rich foods will likely also decrease, helping to reduce body weight, which is a key risk factor for T2D. However, an ongoing problem with healthy diets is that they are not suitable for all cultures and most of the research around them has been conducted in people of European origin, therefore not being applicable to South Asians. Furthermore, people often find it difficult to stick to these diets. (more…)

Why legumes may be the key in the fight against undernutrition

Dr Aaron Lett and Professor Gary Frost explain how Imperial is leading initiatives to address undernutrition in low-middle income countries.


Undernutrition is still a big problem in 2019.

Of the 5.6 million child deaths which occur globally, it is estimated 45% of them can be attributed to undernutrition. The majority of undernutrition occurs in low- and middle-income countries (LMICs) and manifests as stunting, wasting, and underweight.

The World Health Organisation (WHO) reports that today, 155 million children under five years are stunted, 52 million children are wasted, and 17 million are severely wasted. In addition to the negative health impact, undernutrition has significant economic and social implications on these LMICs. Despite current treatments that aim to reverse the nutritional status of individuals with undernutrition, there is still significant morbidity and mortality. (more…)

A teaspoon of salt away from high blood pressure

This Salt Awareness Week, Dr Queenie Chan puts the salt intake guidelines to the test and looks at the reality of curbing salt intake for better heart health. 


Salt and sodium are often used interchangeably, but they’re not exactly the same thing. Sodium is a mineral that occurs naturally in foods or is added during manufacturing or both. Table salt is a combination of sodium and chloride, which was one of the most valuable modes of currency in ancient times. It has been used to preserve food for thousands of years and it is most commonly associated as a form of food seasoning. Salt also plays a role in food processing, providing texture and enhancing colour. (more…)

Festive feasting: the good, the bad and the microbiome

Microbiome

In this festive post, Dr Anjali Amin looks at how to keep our gut microbiome happy over this period of indulgence.

As the festive season approaches, one wonders how our bodies prepare for the enormity of food that will be ingested in a relatively short space of time.  In the UK alone, the average person consumes 7000 calories on Christmas Day alone.  This is three times the recommended calorie intake per day, and most of us will have reached the recommended calorie intake before Christmas lunch has even been served. And of course, it’s not just about eating more. We are also a great deal more sedentary, with the average person in the UK spending 5.5 hours a day in front of the television over the Christmas period desperately awaiting reruns of Blackadder and yet another Christmas special!
