Introduction

Detoxification is defined as a series of therapies that aim to manage acute intoxication and withdrawal. Detoxification refers to the cleansing of toxins from the body of an acutely intoxicated or substance-dependent patient. The main aim of detoxification is to reduce physical harm that could be caused by substance abuse.¹ Sardines are often used as a detoxifying agent because of their rich nutrient profile and composition. Sardines contain nutrients such as Omega-3 fatty acids, proteins, and vitamins. Sardines are relatively small and easy to digest compared to other large fishes, so they are suitable for people who have digestive issues. Proper digestion is considered to be important for detoxification, as appropriate digestion would remove all the waste products and harmful toxins from your body. So, sardines are considered important add-ons to your detoxification diet due to their nutrition profile. It is always important to remember that no single food can detoxify your body alone, a well-balanced diet along with healthy lifestyle practices is key to supporting your body’s natural detoxifying practices.

Detoxification mechanisms

Liver’s role in detoxification

The liver is a vital organ that protects the organism from potentially harmful toxins as it converts lipophiles into water-soluble metabolites that are eliminated from the body through urine.³ The detoxification that occurs in the liver can be broken into 2 categories : 

Phase 1 liver detoxification pathway 

Phase 1 liver detoxification pathway is considered to be a first line of defence against various harmful toxins. This pathway consists of an enzyme group known as cytochrome P450. This enzyme is responsible for neutralising substances such as alcohol and caffeine. These enzymes also offer protection by converting harmful toxins into substances that would be less harmful.

Phase 2 liver detoxification pathway

The byproducts of the Phase 1 liver detoxification pathway could be toxic. These byproducts are usually neutralised by the Phase 2 liver detoxification pathway. These byproducts are neutralised by converting harmful toxins to water-soluble metabolites after which they are excreted from the body.⁴ 

How does sardine liver aid in liver function? 

Sardine liver contains various nutrients and compounds that aid in liver function. These nutrients include Omega-3 fatty acids, B vitamins including vitamin B12, niacin, and riboflavin, and various minerals such as iron, zinc, and magnesium.

Sardine liver is an excellent source of nutrients and vitamins such as vitamin B12, and niacin; and minerals such as iron, and zinc. These nutrients are vital for the enzyme synthesis that is involved in the detoxification pathways in the liver.
