Scientists agree that processed foods are contributing to poor health — but when it comes to ultra-processed foods (UPFs), there’s growing confusion. The term is now used so broadly that it includes everything from crisps and sweets to wholemeal bread and plant-based milks.

Today, we’re exploring the connection between your gut and your brain.
For years, the brain was seen as somewhat detached from other parts of our body, working in isolation above all else. However, emerging research is flipping our idea of the brain on its head.

So, have we been neglect...
