And that comes down to immune dysfunction in particular in many cases.
And then we think about the importance of diet to immune function and inflammation.
then we can see a really key piece of the puzzle that argues for looking at mental and physical health as really two sides of the same coin.
That's exactly right.
It's very difficult to say because there's so many things that make it quite difficult.
to measure depression across countries and across time.
But certainly in young people, there's some evidence from Australia, from the UK and from the US that indeed there has been an increase in the prevalence of psychological distress, symptoms of anxiety and depression in younger age cohorts.
And when we think about dietary change, it's really particularly affected younger people.
And that those apparent increases in prevalence of these psychological symptoms are in accordance with the increases in prevalence of obesity.
And so there's some circumstantial evidence to suggest that that's true.
exercise and diet both impact brain plasticity in particular, the immune system, the gut microbiota and oxidative stress and, you know, body's antioxidant capacity.
We've now got data from three large cohort studies.
So these are studies where we look at mothers during their pregnancy and then we follow them and their children.
And in each of these studies, we've seen that the consumption of unhealthy diets during pregnancy is related to an increased emotional dysregulation in the children that seems to be independent of maternal mental health, postnatal depression.
Even children's diets seem to be clearly related to
their emotional regulation.
We've known for quite a while that those very early life nutritional exposures are related to adult health, such as heart disease, et cetera.
But these data now suggest that it's also relevant for mental health.
And certainly this is backed up by a lot of studies in animal models that look at the impact of unhealthy dietary components during pregnancy on brain and other outcomes in offspring.
Yes.
