AFib Patients: Stop Eating This One Thing (It’s Making Your Rhythm Worse)
AFib Education Center

Sugar and salt aren’t just “diet issues.”
If you have atrial fibrillation, they directly destabilize your heart’s electrical system and can quietly trigger episodes, raise blood pressure, and accelerate AFib progression.
Most AFib patients are never told this — but what you eat every day affects inflammation, atrial stretch, blood sugar spikes, and how stable your heart rhythm really is.
In this video, Dr. Scott Lee explains how two common ingredients silently work against AFib control, why they make episodes more likely, and what simple changes actually help calm your rhythm.
You’ll learn:
• Why sugar spikes adrenaline and inflammation that trigger AFib
• How excess sodium stretches the atria and destabilizes electrical signals
• Why “healthy” processed foods are often the biggest hidden problem
• The difference between triggers vs long-term AFib progression
• Practical, realistic diet changes that support rhythm stability
• How small daily choices can reduce episodes and slow progression
This isn’t about perfection or extreme diets — it’s about understanding what quietly pushes AFib in the wrong direction and how to take back control.

I didn’t know that salt and sugar affects the heart so much. I thought I was doing OK since I maintain a healthy weight (BMI = 21) and my blood pressure is low and my blood sugar level is always normal. Yet if I measured the amount of salt and sugar that I eat it would be too much.
I’ve been dealing with AF for 25 years and have seen many cardiologists during that time. None of them suggested cutting back on sugar and salt to help control AF (or for any other reason). To be fare recently I did see a healthy heart food chart on the wall of one cardiologist (but nothing was said to me).
Good health!
Never had high blood pressure.
Was prescribed 100mg metoprolol which made me feel horrible.
Had a cardioversion 12/30/25 which worked for 2 days.
Stopped metoprolol and felt 2000% better.
Gave up coffee.
Gave up all sugar and white flour.
Added moderate exercise 3x week.
Losing about 1lb a week easily.
BMI is 28.
Had a complete physical Feb 2 and all my other labs normal.
Cholesterol was 149.
A1C was 5.3
Gave up alcohol years ago.
Never added salt and don’t eat salty snacks.
Still have Afib and now starting amiodarone (CORDARONE) today.
And getting a CT on cardiac pulmonary veins
In anticipation of my first ablation procedure.
They say the Dr can and will do a multi-wall ablation and has 70% success rate.
Praying it works.
I’m 67 still working with a young family to support.

Sleep, stress, alcohol, weight, blood pressure, exercise, inflammation, and daily habits all affect rhythm stability more than most patients realize.
