We all know the obvious culprits to avoid if we want to look after our heart.
Smoking, alcohol, and excessive amounts of junk food all clog up arteries and ultimately have a detrimental impact on our cardiovascular health.
We also know that cardiovascular fitness, such as walking, running or cycling, is a great way of making sure our ticker remains in great shape.
Checking my resting and recovery heart rate via my Apple Watch during a bike ride is something I do so frequently, it's practically becoming an unnecessary obsession.
However, when it comes to thinking about foods that directly improve our heart health, the answers might be less obvious. Fruits and vegetables are a given, but why are certain food groups so good for our hearts?
We spoke to experts to find out. Click through the gallery to see five foods that are "powerful armour" for protecting our hearts…
Foods to avoid
So now we know what foods we need to be consuming more of, what should we avoid?
Dr Farah Ahmed, Women's health GP and nutritionist at Dr Farah Women's Health, says: "It's not about never eating your favourite foods, but about limiting the ones that don't support your heart.
"I usually advise cutting back on fried or processed foods that are high in trans and saturated fats. Also, sugary foods and drinks, which increase the risk of diabetes and heart disease, and salty convenience foods, as too much salt can push up blood pressure."
Kezia adds: "The biggest wrecks to your heart are the highly processed foods that pack trans fats, added sugars, and excess sodium. In the long run, processed meats, deep-fried foods, and sugary drinks bring about weight gain and high blood pressure.
"It is a matter of not overly restricting yourself, but of choosing to moderate well. Instead of classifying food as 'good' or' bad', rethink how frequently you eat it.
"The more whole and natural your choices are, the greater will be your heart's thanksgiving for them."
Exercise vs food
Now we've sorted our diet, it's time to think about exercise.
"Exercise and nutrition are more like friends. While diet can cut down on risk factors such as high cholesterol (hypercholesterolemia) or hypertension, physical activity not only strengthens the muscle of our heart but also enhances overall circulation.
"Food provides raw materials needed for energy, healing and repair, while exercise means that these systems – heart, muscle, lungs, as well as liver – operate at optimum efficiency."
