A new study found that people who eat just a half tablespoon of olive oil a day are less likely to die from heart disease, Alzheimer’s or lung disease than people who eat less olive oil.

Specifically, people who consumed more than a half tablespoon a day (compared with people who don’t eat olive oil), had a 19% lower risk of dying from heart disease, a 17% lower risk of dying from cancer, a 29% lower risk of dying from a neurodegenerative disease like Alzheimer’s, and an 18% lower risk of dying from lung disease.

The simple way to take advantage of this information is to simply use olive oil instead of butter, margarine or other oils when eating and cooking.
