Similar Assertions

The immune cells in mice eating olive oil and nuts had fewer 'danger signals' on their surface than those eating a fatty Western diet, making them less likely to trigger inflammation.

77%

When immune cells from mice eating olive oil and nuts were tested in a dish, they absorbed less of the bad cholesterol that clogs arteries than cells from mice eating butter.

71%

The plaques in mice eating olive oil and nuts had fewer inflammatory immune cells inside them than plaques in mice eating a fatty diet.

71%

When immune cells from mice eating olive oil and nuts were provoked in a lab, they released less of the inflammatory chemicals than cells from mice eating butter.
