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.

80%

Mice eating olive oil and nuts had fewer fat-filled immune cells in their blood than mice eating butter, which may help prevent artery damage.

71%

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.
