New Canadian research suggests ultra-processed foods
don't just impact your weight and heart health.
They could also damage your brain.
There were changes in the brain similar to what we call silent strokes
that were not apparent to the individuals,
but we could see them on MRI scanning.
On average, nearly half of the calories Canadians consume come
from ultra-processed foods.
Everything from soft drinks
and packaged baked goods to processed meats.
The study looked at nearly 9,000 adults aged 35 to 69.
It found higher ultra-processed food intake
was linked to higher odds of vascular brain injury,
but not cognitive performance.
While longer-term studies are needed
to see how brain injuries could lead to dementia or future stroke,
researchers believe the connection comes down to inflammation.
Fat tissue in the wrong places can be almost like a furnace spewing out
a whole bunch of inflammatory proteins that then affect our brains.
The study is observational and doesn't prove cause and effect.
Here's how a stroke specialist sees it.
It doesn't mean if you go and have a Snickers bar today or have a slice
of chocolate cake, you're all of a sudden going to have a stroke.
No, it doesn't mean that at all.
He says food studies shouldn't alarm us,
but they can help us eat smarter.
If you have a diet which is rich in these processed foods,
you have a greater probability
of having something happen to you in the future.
To lower that risk, you don't need a total diet overhaul.
For those who can afford it,
studies suggest swapping out just 10% of processed meat
with veggies, nuts and beans helps.
So don't always pick pepperoni.
But if you are picking pepperoni today
because you are busy or whatever,
then don't sweat about it.
As we learn more about how food affects our brain
doctors say it's clear that small but consistent food choices
can make a big difference.
