My name is Sanjay Gupta and I am a cardiologist in the UK I wanted firstly to apologise for not having put out any videos for a couple of months – I think I had tired myself out but hopefully now am feeling a lot better and rejuvenated and plan to start again.
So today’s video is on the subject of atrial fibrillation and in the role of diet in preventing atrial fibrillation The first thing I always say is that any condition can only develop due to four factors: Age Genetics Bad luck Lifestyle We can’t do anything about age, genetics and luck.
We can, however, try the best we can to lead a good lifestyle. In terms of lifestyle, it is, of course, important to ensure that we get a regular cardiovascular exercise, minimise our stress levels and maximise the quantity and quality of our sleep.
Diet is very very important and whilst I always say it is important to eat in moderation, minimise processed foods and alcohol intake, I have never spoken about what kind of diet would be good to prevent Afib. In my research to answer this question, I found an interesting paper that was published in the Circulation journal in 2014. The lead author is Martinez-Gonzalez and basically what the investigators did was about 7500 patients between 55- 80 years who had risk factors such as diabetes, high blood pressure , smoking etc but who did not have atrial fibrillation and randomly assigned them to one of 3 different diets: A Mediterranean diet supplemented with extra-virgin olive oil so they had to consume 50g or the equivalent of 4 or more tablespoons of extra virgin olive oil daily.
A Mediterranean diet supplemented with mixed nuts a control arm which consisted of advice to reduce all types of fat After a follow-up of 4.8 years the trial had to be stopped early because patients on the Mediterranean diet had a lower risk of stroke and cardiac events. 72 patients developed Afib in the MEd+EVO group, 92 in the low-fat diet group and 89 in the Med diet+ nuts group.
They also found that there was a 38% reduction in the relative risk of developing Afib in patients who were on the Mediterranean diet which was supplemented with extra-virgin olive oil. The investigators hypothesised that the reason for the lower incidence of Afib in patients taking the Mediterranean diet with extra-virgin olive oil was due to the anti-inflammatory effects on the oil.
Fib is thought to be brought about by inflammation and inflammatory markers in the blood such as CRP are found to increase the risk of Afib in the future. In this study the EVOO represented 22% of the total calories from the Mediterranean diet.
So I think that although we need lots more studies like this if you are looking to change your diet for the sake of your heart health then I would recommend a Mediterranean diet which is supplemented with at least 4 tbspoonfuls of EVOO. Thank you so much for listening. I will paste the link to the study on my Facebook page. YORKCARDIOLOGY1 I would be really grateful if you’d consider liking,c commenting and sharing. I could really do with more people visiting the channel and my website. Thank you once again
