The Shocking Truth About School Lunches
Never pack these foods in your child’s lunch box
With the dramatic rise in the cost of living, many families are struggling to feed their children, resorting to highly processed packaged foods instead of nourishing whole foods.
Spiralling costs are also putting school catering firms under strain, with many slashing healthier food options from their menus in a bid to save pennies.
According to an analysis carried out by the Journal of Nutrients, UK school children consume the highest level of ultra-processed foods in Europe. After studying the school lunch contents of more than 3,300 primary and secondary school children, they discovered that 82% of calories in packed lunches and 63% of calories in school meals come from ultra-processed foods. 
The decline in healthy school lunches, both homemade packed lunches and school-provided meals, will impact school children around the country.
Learn which foods pose the most risk to your child’s health and how to make school lunches more nutritious.
What are ultra-processed foods?
Ultra-processed foods are convenient (and often cheap), non-perishable packaged foods and drinks that are highly refined and manufactured using preservatives, additives and colourings. These foods are far removed from their natural state, made more palatable by added fat, salt, sugar and artificial sweeteners.
- Ready meals and fast food – pizza, chips, potato waffles
- Mass produced bread – any bread made in a factory
- Breakfast cereals – even those deemed organic, natural and healthy
- Pastries, pies, cakes and biscuits
- Processed meats – sausages, chicken nuggets, hot dogs, ham/ deli meats
- Vegan meat substitutes
- Snacks – cereal bars, crisps, pretzels,
- Yoghurts – especially those marketed at children
- Packaged soups and cake mixtures
- Soft drinks and fruit juices
- Condiments, sauces, dressings
- Margarine and dairy-free spreads
- Pre-packaged cheese slices
- Ice cream and ice lollies
How ultra-processed foods affect health
Children who consume ultra-processed foods have an increased risk of being overweight or obese later in life. It also heightens their risk of type 2 diabetes, cardiovascular issues and cancer in early adulthood.  Highly processed foods are also linked poorer locomotor skills in children aged 3 to 5.
Made primarily with damaged oils, sugar/ artificial sweeteners and chemically-derived additives and preservatives, these foods disrupt metabolism (the conversion of food to energy) and damage cells, preventing the body from functioning efficiently. The toxic effects of these highly processed foods accumulate and wreak havoc in the body, causing a range of health issues including:
- Fatigue and brain fog
- Depression and mood disorders
- Damaged blood vessels
- High blood pressure
- Behavioural problems
- Poor focus and attention
- Asthma and respiratory issues
- Lowered immune function and recurrent infections
- Irritable bowel syndrome and gut disorders
- Skin problems – eczema, acne, dermatitis

- Use shape cutters for sandwiches and fruits/ vegetables – this is a fun way to encourage kids to try new foods. They love seeing their food shaped as hearts, stars or their favourite animal.
- Invest in a stainless-steel bento-style lunch box – with sectioned compartments (around 4-5), you can add a variety of healthy foods without needing lots of separate plastic tubs. It’s easy to pack/wash and doesn’t leak.
- Use some colourful, child-friendly pick sticks for fruit/vegetable kebabs and to hold wraps together.
- Plan lunch boxes for the week to avoid stress and last-minute morning panic. It also allows you to buy all the ingredients you need ahead of time.
- Use up leftovers – extra pasta/sauces/cooked meat can be used the following day in lunch boxes.
