HEALTH

Food that may harm the brain

A big Canadian study links ultra-processed food to early brain damage signs.

THE STUDY

8,700 Canadians took part

They were ages 35 to 69, with no history of heart disease.

WHAT ARE THEY?

Factory-made, fast, and tasty

Chips, sugary cereals, soft drinks, noodles, and frozen meals.

THE TOP GROUP

Nearly half their food was ultra-processed

They ate more than 45% ultra-processed food each day.

THE KEY NUMBER

40% higher risk on scans

Top eaters were over 40% more likely to show tiny brain damage.

SILENT STROKES

Damage with no clear symptoms

Scans showed silent strokes and a pre-stroke profile.

WOMEN HIT HARDER

Nearly twice the risk

Women in the top group were nearly twice as likely to show the signs.

CROWDED OUT

Whole foods lost space

Top eaters got 41% of food from whole foods, versus 68% for the lowest group.

BELLY FAT LINK

More fat, more risk

The top group also carried more deep belly fat.

WHAT HELPS

Small swaps add up

Plain oats, fresh fruit, and home cooking beat packaged snacks.

THE CATCH

A link, not proof

People were checked once, so cause is not proven yet.

WHAT COMES NEXT

New scans due in 2028

Past participants return for new MRI scans to track change over time.
