Considered for years as a natural ally of the cardiovascular system, fish oil is now being called into question. British researchers, in a study published in
BMJ Medicinepoint to unexpected effects on heart health. Their work, carried out on more than 415,000 people followed for 12 years, highlights disturbing results which invite us to reconsider the regular use of this supplement.
Fish oil: no official medical recommendation
The use of fish oil is very widespread. However, as renowned cardiologist Dr. Andrew Freeman points out, “Over-the-counter fish oil is very rarely recommended and is not included in any recommendations from professional medical societies”. A warning that calls for caution, supported in particular by the revelations of a recent British study. The latter showed that regular consumers had a 13% increased risk of atrial fibrillation. Even more surprisingly, among those with no history of heart disease, the risk of stroke was also higher, by around 5%.
Why has fish oil long been considered beneficial for the heart?
Fish oil has long been used for heart health because it is rich in omega-3, essential fatty acids known for their protective effects. Many old studies have shown that these
omega-3 helped to reduce inflammation, reduce
triglyceridesto slightly thin the blood and limit certain heart rhythm disorders. For a long time, fish oil was considered a simple way to support cardiovascular health, before more recent studies qualified this vision.
What healthier alternatives should you choose?
To take care of your cardiovascular health, health experts recommend a balanced and varied diet, in which include natural sources of omega-3 (rather than fish oil): sardines, mackerel, wild salmon, chia seeds, flax seeds and walnuts.
Finally, remember that it is essential to seek the advice of a doctor before starting any supplementation, in order to ensure that it is adapted to our state of health and our real needs.
