This was tested in people. That is the most reliable kind of research we share.
This was a study of gene data in databases, not a test of anything in people.
The short version
This study used gene data to look for links between 6 foods and brain tumor risk.
What was studied. Researchers used gene data already gathered from large groups of people. They checked 6 foods against glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary risk in gene data from 218,792 people.
What they found. In the European data, bread and bacon were linked to a lower risk. In the South Asian data, oat crunch and latte were linked to a higher risk. Danish pastry looked protective, and the chocolate bar link faded after other foods were counted.
What this means, and what it doesn't
What it could mean: Nothing here tells you to change what you eat. It hints that long term eating habits may play some part in risk. The authors say some of these links should be read with care.
What it doesn't mean: This does not mean bread or bacon protects you from a brain tumor. It does not mean oat crunch or latte causes one. No one ate these foods for the study. It only compared gene patterns in databases. This is not a treatment, and it is not a cure. It is far from anything your doctor would act on today.
