While eating fatty food may sound like a bad thing, some fats can play an essential role in keeping your heart healthy.

Many foods we eat contain different fats and some are healthier than others.

Choosing healthy fats can:

Aid healthier blood cholesterol levels.
Lower other cardiovascular (heart) risk factors.
Add flavour to food.

What are the different types of fats?

There are four main types of fats:

Monounsaturated fats
Polyunsaturated fats
Saturated fats
Trans fats.

Healthy (unsaturated) fats

Healthy fats tend to be liquid at room temperature. They include:

Monounsaturated fats
Polyunsaturated fats (omega-3 and omega-6).

Unhealthy fats

Unhealthy fats tend to be solid at room temperature. They include:

Saturated fat
Trans fat.

Replace saturated and trans fats with healthy unsaturated fats as part of a healthy diet.

The relationship between heart disease and fats

Unsaturated fats

Unsaturated fats can help improve cholesterol levels by decreasing bad (LDL) cholesterol and increasing good (HDL) cholesterol. Low LDL cholesterol levels can help lower your risk of heart disease.

Omega-3 fats

Omega-3 fats are a type of polyunsaturated fat that can help:

Lower heart rate and improve heart rhythm.
Decrease the risk of clotting.
Lower triglycerides.
Reduce blood pressure.
Improve blood vessel function.
Delay the build-up of plaque (a fatty substance) in your arteries.

Unhealthy saturated and trans fats

Unhealthy saturated and trans fats can heighten your risk of heart disease by increasing the bad (LDL) cholesterol and lowering the good (HDL) cholesterol.

How much fat should you eat a day?

It’s the big picture that matters. The type of fat you eat is more important than the total amount.

You can get the balance of fats right by:

Swapping unhealthy fats for healthy fats in your diet.
Enjoying a combination of heart-healthy foods regularly over time.
Follow our guidelines for eating for a healthy heart to helps provide you with the right balance of fats.

Margarine
Milk
Yoghurt
Breakfast cereal.

Eat less unhealthy fat-containing foods

Saturated fats

Saturated fats can be found in both animal and plant products. When eating less saturated fat, the foods you replace it with are important. Follow the Heart Foundation’s heart healthy eating pattern to achieve a healthy mix of fats.

Foods that commonly contain saturated fats include:

Butter
Coconut oil
Palm oil (often called vegetable oil in products)
Processed foods, such as biscuits, cakes, pastries, pies, and takeaway foods

Some trans fat-containing foods to eat less of include:

Deep-fried foods
Biscuits, cakes and pastries
Butter
Takeaway foods, such as hamburgers, pizza and hot chips
