I recommend checking out Gill Carvalho (https://www.youtube.com/@NutritionMadeSimple). He helped me realize that nutrition science isn’t a controversial as it would seem from reading the popular press or the occasional study showing that bacon and Oreo cookies are good for your heart. It took five or ten videos to get a feel for how real scientists interpret new information. He explains the relative power of different types of scientific evidence, etc. Good stuff. He covers the Omega-3 AFib connection. If I remember correctly, Omegas-3s improve several cardiovascular risk factors, but also increase the risk of AFib. So, depending on your current situation, you may want to increase or decrease your intake. Deficiency is definitely bad, but you can also overdo it. I decided that sardines a few times a week is probably safer for me than the fish oil capsules I was taking daily.
