How fibre and gut bacteria can reverse stress damage

Due to the fast-paced world we live in, stress has become endemic and many of us want a solution to counteract the harmful effects that stress can have on our bodies. The bacteria that live in our gut aka our microbiome has become more and more recognised as a key factor in mental health issues, such as depression and anxiety. This is due to the gut-brain connection, such as when we are feeling nervous or tense it can speed up our bowel movements, or vice-versa. If we haven’t eaten in a while we can become ‘hangry’. A troubled brain can affect the gut, and a troubled gut can affect the brain.

Although stress is a mental state, it can have a physical effect on our gastrointestinal system and the bacteria that reside within it. A study published in Nature Journal found that high levels of stress can affect gut bacteria to a similar degree as a high-fat diet, while other studies have shown that reducing the number of bacteria in the gut can produce stress-induced activity in mice. This indicates that stress can alter gut bacteria, and gut bacteria in turn can impact stress levels.

A team of researchers at University College Cork and Teagasc Food Research Centre in Ireland found that when short-chain fatty acids (SCFAs) were introduced to the guts of mice, stress and anxiety-based behaviours were significantly reduced. They found that the SCFAs reduced the gut leakiness caused by persistent stress. This allows us to deduce that a high-fibre diet might prompt gut bacteria to produce more SCFAs – thereby boosting our gut’s natural defences against the damage caused by stress.
