Many of us start January with good intentions around healthier eating, especially when we are feeding children too. But new research suggests that one of the foods most families eat every day could be far more processed than we realise.

A nationwide campaign called Rye January is launching this month, encouraging households to swap their usual sliced bread for rye bread, after a study found widespread confusion about what actually goes into everyday loaves.

New figures show that nearly three in four Brits are unable to identify common additives and preservatives found in standard sliced bread, despite growing concern about ultra-processed foods.

Most Brits do not know what is in their bread

Research released by organic food brand Biona reveals that 73% of Brits cannot identify the 10 most common additives and preservatives found in everyday bread.

Even more striking, 93% of those surveyed were unaware that the average sliced loaf can contain as many as 19 additives and preservatives. Around 40% believed the number was under 10 ingredients.

Bread is now the most processed food eaten daily for one in seven people in the UK. This comes despite more than a third of Brits becoming increasingly focused on understanding the chemicals in their diet, reflecting a wider shift among parents who want to make healthier choices for themselves and their children without overhauling everything at once.

For busy parents grabbing toast at breakfast, sandwiches for packed lunches and quick meals after school, bread is often a daily staple, which makes these findings particularly relevant for families.

The challenge, as many mums know, is finding swaps that feel realistic, affordable and family-friendly.

What is Rye January?

Rye January is a new nationwide challenge backed by Biona and Dr. Rupy Aujla, a TV doctor and GP best known for The Doctor’s Kitchen. The campaign encourages people to swap their usual sliced bread for rye bread throughout January and share how they feel.

Rye bread is traditionally fermented and is part of the sourdough family. Biona says its rye bread is made with just four organic ingredients, using a traditional fermentation process, and is yeast, wheat and dairy free.

The idea is not about restriction, but about a simple switch that could support better health during a month when many families are already thinking about fresh starts.

The potential health benefits of rye bread

Dr. Rupy Aujla said: "As a GP, I always encourage people to make simple swaps to everyday food items that can have significant health benefits and rye bread is one of these."

Studies suggest rye bread may offer a number of benefits compared to standard sliced bread. Research has shown it can help improve blood sugar control, reduce cholesterol by up to 14%, and keep people feeling fuller for longer thanks to its high fibre and low GI profile.

Participants in the Rye January challenge are encouraged to notice any changes in their energy levels, digestion and hunger patterns, something that may appeal to parents looking for foods that keep them satisfied through busy days.

"Rye bread is also fermented and wheat and yeast free so a brilliant nutritious, real food to add into your diet. Biona’s rye bread wins for me as it contains only 4 organic ingredients," Dr. Rupy says.

Why this matters for families

Nearly one in three people surveyed (29%) said they are increasingly focused on understanding what chemicals are in their diet, making the timing of Rye January particularly relevant.

Rye bread is already gaining popularity in the UK, with 29% of people saying they have tried it. For parents, it could be an easy alternative for breakfasts or lunches without overhauling the whole family menu.

As January’s healthy eating push continues, Rye January adds another option alongside Veganuary and Dry January to encourage people to make small, manageable changes that fit into every day life.
