If adults get 5% more of their daily calories from healthy fats like those in olive oil or avocados, they might have a slightly lower chance of dying from any cause over time.

Eating a bit more healthy fats like those in nuts and fish—replacing things like carbs or saturated fats—might help people live longer and lower their chances of dying from heart disease or cancer.

Even a tiny bit more trans fat in your diet — just 1% of your daily calories — could raise your chances of dying from heart disease or other serious illnesses by 6%.

Eating less saturated fat (like butter and fatty meats) and more healthy fats (like olive oil, nuts, and fish) is linked to people living longer and having fewer heart problems or other serious illnesses.

If you swap out a little bit of butter and fatty meats for healthier fats like nuts and fish oil, you’re less likely to have a heart attack or die from heart disease — it’s not about eating less fat, but choosing better kinds of fat.

Eating more fat in your diet doesn't seem to make you more likely to die from heart disease, according to long-term studies of nearly 90,000 people.
