I thank my hon. Friend the Member for Stourbridge (Suzanne Webb) for securing this important debate on a subject that is really close to my heart.
Most people are now aware of the health impacts of HFSS diets, yet it is increasingly clear that the primary cause of diet-related disease is not a diet that is high in fat, salt and sugar, but rather one that is high in UPF. However, as has been said, I wonder how many people know what UPF is and what it stands for, even though it represents 60% of the average UK diet.
To put it simply, if a food is wrapped in plastic, has at least one ingredient that we would not usually find in a standard home kitchen, or has a health claim on the packet, it is likely to be UPF. Much of it will be familiar as junk food, but there are also plenty of organic, free-range and “ethical” ultra-processed foods that might be sold as healthy, nutritious, or useful for weight loss.
Home-made chips, lasagne and cake are not the same as their UPF equivalents. The processing is what is important—so we do not have to all give up cake, as long as we make it ourselves. When we think about food processing, most of us think about the physical and chemical things done to food, but the definition of ultra-processing includes its purpose: to create profitable, convenient, hyper-palatable products. Those indirect processes—marketing, legal challenges and lobbying—all make the issue of how to tackle the health impacts of ultra-processed foods more complicated.
The evidence on ultra-processed food is robust. It is not just a couple of trials; hundreds of papers and high-quality data show the wide-ranging health impacts. Many people are unaware of how artificial the designs of ultra-processed foods are. They typically contain little, if any, whole food. The food’s structure is destroyed by industrial processing, meaning that UPFs are usually soft. They are therefore easy to eat quickly, which means that people eat far more calories per minute and do not feel full until long after they have finished eating. UPFs contain drastically reduced levels of phytochemicals, which are essential for dietary health and cannot be replaced through supplementation. There are also extensive environmental effects. The monocultural food system necessary for the production of UPFs is a leading cause of declining biodiversity and the second-largest contributor to global emissions.
If they are so bad for us, why do we eat them? Highly processed foods are on average three times cheaper per calorie than healthier foods. People from households with lower financial security or food security report consuming fewer fruit and vegetables, less fish and more sugar-sweetened soft drinks than those who are more financially secure.
The rise of UPFs is an emergent property of today’s commercialised and commodified food systems. Many people feel food systems have become more profit driven, with natural and fresh food less accessible. For example, buy-one-get-one-free offers in supermarkets often tempt us to buy more but, in 2015, supermarket promotions in Britain were the highest in Europe, with around 40% of our food expenditure going on promoted products.
Lord Hague recently wrote a fabulous article that argued that it now seems extraordinary to us that tens of millions of people used to smoke cigarettes without realising the serious harm they could cause. I suspect that when people look back a few decades from now, they will have a similar sense of incredulity about the food we eat.
One in 20 UK cancer cases is down to excess weight, which is the second largest preventable cause of cancer after smoking. Diet-related disease is the leading cause of early mortality, with the primary cause being high-UPF diets. Two in five children in England face ill health as a result of the food they eat. Those children are five times more likely to develop serious and life-limiting diet-related conditions in adulthood.
We must re-design our food system to put health first. That our diets should be made up mainly of real food seems simple. Individual responsibility is important but, to facilitate it, we must ensure that as many children as possible finish school with the knowledge and ability to cook healthy and nutritious food for themselves. I am arguing for a proactive approach to public health that equips people with the tools and information they need to make informed, healthier choices. We must also increase the powers of local authorities to empower their communities to address their unique health challenges by, for example, tackling the flood of unhealthy food and drink advertising in outdoor areas, especially near areas where children congregate.
The levy on sugar and soft drinks has been an enormous success. The sugar removed from the national diet as a result is estimated to be equivalent to the weight of 4,000 double-decker buses, without leading to a fall in sales. Fiscal measures can incentivise—
I am sorry to interrupt the hon. Lady’s flow. Sugar may have been removed from soft drinks, but other things have gone in. We have already heard about aspartame, which is a particularly horrible sweetener. We know that the levy has taken a huge amount of sugar out, but it has not had any impact on obesity, particularly childhood obesity, so maybe we need to look at other things too.
I entirely agree with the hon. Lady. If I had my way, fizzy drinks would be banned from all schools and would be hugely discouraged wherever they are sold, but at least the money raised from that tax helps to educate people that we need to look at what we are drinking and eating.
I will not take up more time, but I want to make the case that we have good reason to look closely at the food that finds its way on to the nation’s plates, and we should take ways to tackle the health impacts of ultra-processed foods seriously, renew our commitment to halving childhood obesity by 2030, reduce diet-related inequality and create a long-term shift in our food culture.
