A NATURAL compound found in three foods may protect against heart attacks, say scientists – and could be more effective than existing treatments.
Ferulic acid, a naturally occurring antioxidant, has been found to prevent coronary artery spasms, which can cause chest pain (angina), heart attacks, and other serious cardiovascular issues.
Using pig coronary arteries, which closely resemble human heart arteries, a research team from Toho University in Tokyo, Japan found ferulic acid significantly reduced artery contractions caused by chemical stimuli.
And it did this through two separate mechanisms.
The first was it blocked calcium from entering muscle cells through L-type calcium channels, which are normally responsible for causing the arteries to contract.
Secondly, even when calcium is not involved, it still prevents the arteries from tightening by inhibiting the activation of a specific protein called myosin light chain, which is essential for muscle contraction.
Surprisingly, the researchers also found ferulic acid could be even more effective than diltiazem – a widely used medication for relaxing blood vessels.
“Because ferulic acid is plant-based and considered safe, it may have potential as a health food ingredient or even as a foundation for future heart medications,” said lead researcher Dr Kento Yoshioka.
The researchers added the study opens the door to new, natural ways of supporting heart health, including through diet or supplements in the future.
Ferulic acid is found in a number of foods, including rice, coffee and spinach.
And its benefits have been found to reach far beyond heart health.
Ferulic acid may benefit the skin in various ways.
The compound may help neutralise atoms called free radicals that break down the body’s cells and contribute to ageing.
A 2018 review found ferulic acid acts as a “free radical scavenger,” seeking out these atoms and neutralising their damaging effects.
It may also help reduce sun-induced skin damage.
A 2018 study found adding ferulic acid to sunscreens can raise their SPF and may prevent inflammatory skin reactions.
And it could also reduce skin inflammation.
The 2018 review found ferulic acid may calm inflammation associated with acne, hyperpigmentation, and seborrheic dermatitis.
When used cosmetically, ferulic acid is usually safe for the skin and human health.
But in rare cases a treatment containing the antioxidant may cause mild irritation and/or redness, as well as itching.
Other ways to reduce your heart attack risk
Quit smoking
Smoking is a major risk factor for heart disease. Quitting, regardless of how long you’ve smoked, can dramatically lower your risk.
Maintain a healthy weight
Being overweight or obese increases your risk. Losing even a small amount of weight can make a difference.
Exercise regularly
Aim for at least 150 minutes of moderate-intensity aerobic exercise per week. Examples include brisk walking, swimming, or cycling.
Eat a heart-healthy diet
Focus on fruits, vegetables, whole grains, lean proteins (like fish and beans), and healthy fats. Limit saturated and trans fats, cholesterol, and sodium.
Manage stress
Chronic stress can contribute to high blood pressure and other risk factors. Find healthy ways to manage stress, such as exercise, spending time with loved ones, or practising relaxation techniques.
Limit alcohol consumption
If you drink alcohol, do so in moderation. For women, this means up to one drink per day, and for men, up to two.
Manage existing conditions
If you have high blood pressure, high cholesterol, or diabetes, work with your doctor to manage these conditions effectively.
Get enough sleep
Aim for seven to nine hours of quality sleep per night. Poor sleep can negatively impact heart health.
Regular checkups
See your doctor for regular checkups to monitor your heart health and address any potential issues early.
