Ultra-processed foods (UPFs) have become the recurring villain in our media and the endless advice on what we should or should not eat makes it almost impossible not to feel constant doubt over everything we put on our plates.

Research from the UK FSA, published late last year shows that 78% of adults are concerned about UPFs, making it the second-highest food worry after food prices, which concerned 91% of respondents.

The tension between cost and health is forcing compromise between affordability and what is good.

Registered nutritionist and recipe development manager, Lily Keeling from leading healthy recipe box service, Green Chef, suggests this unease comes from how difficult it is to balance convenience, cost, and nutrition.

She explains, “Health concerns and food prices can create a relentless cycle of compromise, often pushing people towards cheaper and often more highly processed foods.”

“Even as concern over ultra-processed items grows, cost pressures make it hard to avoid products high in sugar, salt, and additives, worsening the gap between health awareness and what people can afford,” she adds.

Lily does, however, caution that not all UPFs carry the same risks, and some can be part of a balanced diet when consumed in moderation or chosen carefully.

She notes, “People often overlook that not all UPFs are created equally because the ‘ultra-processed’ label describes how a food is made rather than its actual nutritional value. Many UPFs, such as fortified wholegrain cereals and baby formula, provide essential fibre, vitamins, and nutrition that actively support health.”

“While we should limit “hyper-palatable” UPFs like fizzy drinks or sweets that are high in sugar and salt, dismissing the entire category can lead to unnecessary food anxiety and the exclusion of affordable, nutrient-dense staples,” she clarifies.

According to Lily, these everyday foods are some of the biggest hidden ultra-processed offenders that many consume without realising, beyond the obvious culprits like pizzas, ready meals, and sugary snacks.

Flavoured yoghurts

Flavoured yoghurts are often assumed to be a healthy snack, but many are packed with added sugars and stabilisers that can push them into the UPF category. The fruit may be more syrup than actual fruit, and the texture is often adjusted with emulsifiers.

She explains, “People think a flavoured yoghurt is a straightforward source of protein and calcium, but once you look at the ingredient list, there’s often more sugar than fruit and several additives designed to prolong shelf life and alter texture.”

For those trying to balance convenience and nutrition, plain yoghurt with fresh fruit or a small drizzle of honey can offer the same taste with far fewer processing concerns. Ideally, choose yoghurts without fruit syrups, corn syrup, carrageenan, or flavouring chemicals.

Pre-sliced sandwich breads

Packaged sliced breads may appear harmless, but they often contain enzymes, preservatives, added sugars and various other additives that extend shelf life and keep each slice unnaturally soft. Even wholegrain varieties can have a surprising number of additives.

“Consumers rarely realise how much of the bread is engineered rather than baked,” Lily says. “A slice may seem simple, but the number of stabilisers and emulsifiers can make it one of the most processed items, which can be a problem if shop-bought bread makes up most of your carbs.”

She adds, “In fact, regularly eating highly processed bread can contribute to sustained blood sugar imbalances, increased cravings, higher calorie intake, and over time may raise the risk of insulin resistance, and related metabolic issues.”

Switching to fresh loaves with no additives like sourdough or baking at home is more than a nostalgic nod to the past; it reduces exposure to these hidden ingredients. Opt for breads with the shortest ingredient lists possible, ideally made from little more than flour, water, yeast, and salt.

Ready to drink smoothies and juices

Bottled smoothies and fruit juices are often seen as a shortcut to five a day, but many are heavily processed to preserve colour, flavour, and shelf life. Even when made from real fruit, they can contain fruit concentrates, added sugars, stabilisers, and flavourings.

Lily explains, “Once fruit is blended, filtered, and stored for extended periods, it often behaves very differently in the body. A smoothie or juice with added sugar and preservatives is not as beneficial as it can cause more rapid blood sugar spikes and crashes, and contains less natural fibre than whole fruit.”

Choosing whole fruit, or making smoothies at home where the skin and fibre remain intact, gives you control over ingredients, avoiding any additives and other processing.

Tinned soups

Tinned or cartoned soups are often perceived as a convenient, healthy option, yet many rely on thickeners, flavour enhancers, and preservatives to maintain consistency and taste. Vegetables may be present, but often in much smaller quantities than the label imagery suggests.

“These foods sit in an uncomfortable middle ground,” Lily notes. “They look wholesome, but the ingredient lists often tell a very different story which can make it harder to judge the real nutritional value of what you’re actually eating.”

A single afternoon spent batch cooking soup can create enough healthy and nutritious meals to last for months, and can be used as a convenient base for quick lunches or dinners throughout the week.
