In different countries, people who eat more saturated fats, trans fats, and cholesterol tend to have more heart disease deaths — this pattern was noticed when scientists compared diets and heart disease rates around the world.

In different countries, people who eat more saturated fats, trans fats, and cholesterol tend to have higher rates of heart disease deaths over 25 years — and this pattern shows up when you compare countries.

People in different countries die from heart disease at different rates, and this might be because of how much saturated fat, trans fat, and cholesterol they eat.

Among middle-aged American Indians, people who ate more fat — especially saturated fat — were more likely to die from heart disease than those who ate less, even when other health factors were taken into account.

In countries where people eat more cholesterol from food, more people tend to die from heart disease over 25 years — and this pattern shows up consistently across 16 different groups of people in seven countries.

Eating more saturated fat — like in butter or red meat — doesn't appear to raise the chance of dying from heart disease, based on long-term studies of nearly 90,000 people.
