Ultra-processed food causes weight gain – firm evidence at last

We know we should eat less junk food, such as crisps, industrially made pizzas and sugar-sweetened drinks, because of their high calorie content. These “ultra-processed” foods, as they are now called by nutritionists, are high in sugar and fat, but is that the only reason they cause weight gain? An important new trial from the US National Institute of Health (NIH) shows there’s a lot more at work here than calories alone.

Studies have already found an association between junk foods and weight gain, but this link has never been investigated with a randomised controlled trial (RCT), the gold standard of clinical studies.
In the NIH’s RCT, 20 adults aged about 30 were randomly assigned to either a diet of ultra-processed foods or a “control” diet of unprocessed foods, both eaten as three meals plus snacks across the day. Participants were allowed to eat as much as they wished.

After two weeks on one of the diets, they were switched to the other for a further two weeks. This type of crossover study improves the reliability of the results since each person takes part in both arms of the study. The study found that, on average, participants ate 500 calories more per day when consuming the ultra-processed diet, compared to when eating the diet of unprocessed foods. And on the ultra-processed diet, they gained weight – almost a kilogram.

Although we know that ultra-processed foods can be quite addictive, the participants reported finding the two diets equally palatable, with no awareness of having a greater appetite for the ultra-processed foods than for the unprocessed foods, despite consuming 500 calories more of them per day.
Unconscious over-consumption of ultra-processed foods is often attributed to snacking. But in this study, most of the excess calories were consumed during breakfast and lunch, not as snacks.

Slow eating, not fast food

A crucial clue as to why the ultra-processed foods caused greater calorie consumption may be that participants ate the ultra-processed meals faster and so consumed more calories per minute. This can cause excess calorie intake before the body’s signals for satiety or fullness have time to kick in.
An important satiety factor in unprocessed foods is dietary fibre. Most ultra-processed foods contain little fibre (most or all of it is lost during their manufacture) and so are easier to eat fast.

Anticipating this, the NIH researchers equalised the fibre content of their two diets by adding a fibre supplement to the ultra-processed diet in drinks. But fibre supplements are not the same thing as fibre in unprocessed foods.

Fibre in unprocessed food is an integral part of the food’s structure – or the food matrix, as it’s called. And an intact food matrix slows down how quickly we consume calories. For instance, it takes us far longer to chew through a whole orange with its intact food matrix than it does to gulp down the equivalent calories as orange juice.

An interesting message emerging from this and other studies seems to be that to regulate calorie intake, we must retain food structure, like the natural food matrix of unprocessed foods. This obliges us to eat more slowly, allowing time for the body’s satiety mechanisms to activate before we have eaten too much. This mechanism does not operate with ultra-processed foods since the food matrix is lost during manufacture.

Finding time for a meal of unprocessed foods eaten slowly can be a real challenge for many. But the importance of seated mealtimes is an approach vigorously defended in some countries, such as France, where a succession of small courses ensures a more leisurely – and pleasurable – way of eating. And it may also be an important antidote to the weight gain caused by grabbing a quick meal of ultra-processed foods.The Conversation

Top 5 tips for making the most of your summer

Summer is finally here, you’ve done your exams and your assignments, it’s finally time for some sunshine, ice cream and holidays. I’m sure you can’t wait! Here are some top tips that I would recommend to make the most of your summer:


1.    Keep in contact with your friends

It sounds cliché, but you will miss your friends from university, you’ve lived with them or gone to classes with them every day for at least a year, so it can be strange going from seeing a group of people every day to not seeing them at all. So, you should certainly keep in contact with your friends from university, make sure to give them a call every now and again for a chat about how your summer holidays are going. Or if you can, meet up with your friends, even though you may be a long way away from each other, try and designate a day where you can travel to one of your friends, or chose a halfway destination which is convenient for everyone.

2.    Think about getting a job

Of course, you need some relaxation time and some time to yourself but at the same time, you need to think about your future. Working over a summer, or even doing a couple of weeks work experience, can really help you stand out and give you more examples and transferrable skills to talk about in future job interviews. Try and find something in the field you study in, as that would help enhance your CV. It is also a great opportunity to meet new people and get some good contacts for the future, along with that, it can help get you out of the house. 

3.    Be Active

Don’t turn into a couch potato this summer, it is important to stay active, get out and about, do some exercise whenever you can, just make sure you leave the house. I’m sure we’ve all been guilty of wasting a weekend or even a summer staying in, watching tv and eating junk food. Unsurprisingly, that isn’t great for your health, don’t forget about staying healthy this summer, eat right and be active. Go out when you can - if you go to the gym, keep that up - if you regularly play sports, keep that up. If you’re local, head down to the Hertfordshire Sports Village, which will be open during summer, check out some of their activities on the website.

4.    Tick something off your bucket list

We’ve all got things we really want to do; we’ve all got a bucket list. Well now you’ve got this free time, why not do something from your list. It could be anything from skydiving to wanting to travel to a different country, it’s your list! Whatever it is, this summer is the ideal time to tick something off, so go do something you’ve always wanted to do! 

5.    Relax


Have some time to yourself. You’ve stressed over your exams and had long nights of writing assignments; you deserve a bit of time to relax. I wouldn’t recommend relaxing all over summer, as you may have other responsibilities or a job, so relax but don’t completely switch off. Again, you deserve this!

Favourite thing about the University

MyHerts have spoken to some final year students, who are about to finish their time at the University. We wanted to find out about their favourite Herts Moments from this academic year. Here’s what they had to say:


Christian Lavelle:
“My favourite thing about the university is that there is so much to offer. From Active Students to student-led societies to help with planning for my future career. For example, after joining the creative writing society, I was able to socialise with students from other courses that I would otherwise have not met, this was really good for me as I was able to make more friends and feel part of the wider university community.”

Mansi Joshi:
Without a doubt, my favourite thing about my time at university has been the people I have met along the journey. I met one of my best friends on the first day of uni. I knew no one, we were both waiting for the same lecture and started chatting. 4 years on and we are still inseparable. I had the opportunity to get to know others in my lectures and my new flat mates, who despite being the weirdest mix of people, got along like a house on fire. It is crazy to think that had I not joined societies and met these people, I would not have embarked on the adventure of a lifetime; having the opportunity to go on exchange to Australia. During my year in Melbourne, the ‘people meeting’ continued and I made some wonderful friends for life from countries all over the world. I even got the chance to travel to some of these places and experience immersing myself into these colourful cultures as a local. Meeting new people is an inevitable part of life, but for me, university has been the perfect place to experience the highs as well as lows of friendship and building relationships. It has both taught me lessons and given me some incredible memories which will stay with me for life.”

Natasha Pensado:
“The three years that l have spent at the university have been amazing and it is difficult to pinpoint my favourite thing about university because of the various positive experiences l have had. The university has given me the opportunity to meet people from different backgrounds and make new friends and professional relationships. The experiences l had have helped me in working towards my dream career. The learning atmosphere has been positive in that my lecturers have been supportive, knowledgeable, approachable and always willing to help. The university has held networking events where l had the chance to meet people working in the legal sector such as the Crown Prosecutor for the West Midlands and they have given me great advice. The university has also provided me with great opportunities to develop my skills through extracurricular activities such as mooting and client interviewing, and l was given the opportunity to visit the major circle firm Clifford Chance in London. The university has enabled me to develop socially, personally, professionally and I have been given a strong foundation to expand my horizons.”

Summer on My Mind

When we think of the summer time, we think of lazy days chilling out in the sun, eating ice cream or drinking with friends, without a care in the world.


But, for many of us, the summer months aren’t always that simple!

As a student, your experience of the summer will depend on lots of factors – whether you’re on placement or working, whether you have re-sits to take, and if you’re on a course that runs throughout the summer months.

For those who need to remain in Hatfield over the summer, the vacation can sometimes pose a challenge, in that you may not have so many friends, and people who can support, around you. Or, if you’ve gone back home for the holidays, adjusting to living with family again after living more independently all term can feel a bit tricky too! In both scenarios, it’s important to reach out to friends and find ways of structuring your time so that you don’t end up feeling isolated and disconnected. And if you’re struggling with how you’re feeling and will be local to Hatfield, remember that Student Wellbeing remains open during the vacation.

But what about taking time out for rest, relaxation and fun?

For some, it may not be realistic to be able to take long periods of care-free holidays but try to give yourself some downtime where you can relax and recharge. If you’re the kind of person who finds it hard to give yourself a proper break, remind yourself that taking time out can give your brain an opportunity to make sense of what you have learned so far and should also allow you to feel fresher and more able to focus when you do get back to your academic studies.

And if you’re off travelling this summer, then try to enjoy the new opportunities and adventures you may face. But maybe don’t put too much pressure on yourself for every day to be awesome and perfect. Holidays can be amazing, but much like the rest of life, there may also be more difficult times. Work out in advance who you can contact if things get tough and make contingency plans in case you need to come home earlier than planned.


There are some things which none of us can control or predict - such as the “Great British weather” and (dare we mention it?) the developing political situation in the UK! But looking after ourselves, keeping in touch with friends and reaching out for support when needed, is something we can all try to work on.

Prepare for your summer holidays with the Campus Pharmacy

Are you heading off to anywhere nice on holiday this summer? It’s important to ensure you’re fully prepared for your adventure and what lies ahead, including making sure you’re up to date with your travel vaccines. Don’t overlook how important they can be, they can be life savers sometimes! The campus pharmacy shares how they can help you prepare for your summer holiday adventures.


Learn about your destination country. Travel vaccines can vary by destination, so even if you’ve recently been abroad and had vaccines, you may need different ones for your new destination. In some countries, just an ice cube in a cocktail can make you need to run to the bathroom 20 times a day, sweat through a fever, have bad cramps and suffer from serious fluid loss. Not the most ideal way to spend your summer holiday, is it?

Make sure to get vaccinated in plenty of time, it is recommended to get vaccinated at least 4 to 6 weeks before you travel. This gives enough time for the vaccines to start working, so you’re protected while you’re travelling. Some vaccines require more than 1 dose, so remember to leave enough time to get the multiple doses you may need.

If you are someone who suffers with chronic illnesses but you’re still planning to travel abroad, make sure you’re in the know about your illness. The Campus Pharmacy can help provide some general information for you to help you prepare for your trip.

Along with this, the Campus Pharmacy can provide a range of medicines and products available to purchase to both prevent and treat minor ailments whilst abroad. Some examples of minor ailments are colds, coughs, earaches, hay fever or a sore throat. 

The Campus Pharmacy can supply administration of all travel vaccines except for Yellow Fever. They can even supply malaria prophylaxis without a prescription. So, with all these right at your front door, why not head down and make sure you’re vaccinated correctly for any summer holidays you have planned. You can call them on 01707 284054 or pop in to the Campus Pharmacy in Hutton Hub, College Lane, to book an appointment and find out which vaccinations you may need along with prices. They are open Monday to Friday 9am-5pm (9-4 on Fridays).
