Why Is Fermented Cod Liver Oil Bad?

Fermented cod liver oil has been a popular supplement for many years, touted for its numerous health benefits. However, recent studies have shown that it may not be as beneficial as previously thought. In fact, fermented cod liver oil may actually be bad for you.

What is Fermented Cod Liver Oil?

Fermented cod liver oil is made by fermenting the livers of cod fish in a barrel with added salt. This fermentation process is said to enhance the nutrient content of the oil and make it more easily digestible.

Why is it Bad?

While many people swear by fermented cod liver oil, there are several reasons why it may not be good for you.

1. High Levels of Mercury

Cod fish are known to contain high levels of mercury, which can be harmful to your health. While some manufacturers claim that their fermented cod liver oil is low in mercury, there have been no studies to back up these claims.

2. Rancidity

Fermented cod liver oil is prone to rancidity due to the fermentation process. Rancid oils can cause inflammation in the body and may even lead to cancer.

3. Vitamin Toxicity

Fermented cod liver oil is often marketed as a rich source of vitamins A and D. However, excessive consumption of these vitamins can lead to toxicity and cause serious health problems.

What Should You Do Instead?

If you are looking for a healthy source of omega-3 fatty acids, consider taking fish oil supplements that have been purified and tested for contaminants like mercury. Additionally, eating oily fish like salmon or sardines can also provide you with the same benefits without the risks associated with fermented cod liver oil.

In conclusion, while fermented cod liver oil has been touted as a miracle supplement, recent studies have shown that it may not be as beneficial as once thought. With high levels of mercury, rancidity, and the potential for vitamin toxicity, it is best to look for alternative sources of omega-3 fatty acids.
