Summary

Story at-a-glance

A high-fat diet makes it easier for breast cancer to spread by activating clotting cells, increasing inflammation and altering blood vessels in ways that help tumors grow
Mice on high-fat diets had nearly five times more cancer cells in their lungs, even when their tumors were the same size as leaner mice
A high-fat diet increased fibronectin, which acts as "molecular glue" helping cancer cells attach to blood vessels, while obesity increases inflammatory compounds that worsen this buildup
Switching to a normal-fat diet for just seven days significantly reduced clotting activity, fibronectin buildup and the number of cancer cells lodging in the lungs
Eliminating vegetable oils and reducing total fat intake to 30% to 40% of daily calories lowers inflammation and reduces your risk of cancer spread

0:22.0	wisdom. I'm Ethan Foster and today we're examining new research showing that a high fat diet
0:28.0	can prime your bloodstream, your platelets, and your blood vessels to help breast cancer spread.
0:33.8	Joining me is co-host Alara Sky here to break down the findings so you can understand exactly
0:39.3	what's happening inside you and what you can do about it.
0:42.3	Thanks, Ethan.
0:43.3	Metastatic breast cancer becomes life-threatening, not because of the first tumor, but because

0:51.3	The study we're discussing zeroed in on triple negative breast cancer,
0:55.0	the fastest moving, hardest to treat form. When 60% of daily calories came from fat,
1:01.0	researchers saw three major shifts. Your blood became stickier, your vessels leakier,
1:06.0	and a protein called fibrinectin accumulated, creating favorable spots for traveling cancer cells to take hold.
1:13.5	The investigators wanted to understand how food choices lay the groundwork before any rogue cell
1:18.5	even leaves the primary tumor. They compared mice on a standard diet with those consuming
1:23.6	60% fat and tracked platelet behavior, fibro-nectin buildup, and vessel leakiness in the lungs.
1:31.3	Why are those three elements so critical when you're talking about triple negative breast cancer?
1:36.3	The results were striking. First, platelets, the clotting cells in your blood, became hyperactive.
