Best Cooking Oils to Reduce Inflammation in Arthritis

The body's immune system has a natural capacity to fight foreign bodies that enter it.

This defense mechanism helps the body survive against diseases.

This process gathers many defense cells and causes redness and swelling in the area which is termed as inflammation.

Inflammation is caused in numerous medical conditions.

Sometimes due to a malfunction in the body, the defense mechanism of the body attacks its own cells leading to inflammation which is seen in some cases of diseases like rheumatoid arthritis.

Arthritis is one such condition where the joints are inflamed leading to swelling, pain and joint stiffness.

Arthritis symptoms can disable a person from performing day to day activities.

Dietary factors have been identified to influence the inflammation causing chemicals.

Certain foods can increase the chemicals and some others can decrease them.

Therefore, diet modification is one of the suggested non-medicinal therapies for arthritis.

Before we discuss the cooking oils that benefit arthritis, let us know some more about their composition, uses, and effects on inflammation.

Importance of Saturated, Polyunsaturated, Omega-3 and Omega-6 Fatty Acids and Their Link with Inflammation in Arthritis

Fatty acids are components which are required by the human body to function in a normal way.

It is involved in producing energy, synthesis of hormones and formation of cell membranes of the body.

Fats are required for the absorption of vitamins in the body.

Fatty acids are classified into saturated fats and unsaturated fats based on their chemical structure.

Unsaturated fatty acids are divided into monounsaturated and polyunsaturated fats.

Polyunsaturated fatty acids (PUFA) include omega-3 and omega-6 fatty acids.

Saturated fats are a type of fatty acids that are mainly present in the animal-based products like meat and dairy products.

Saturated fats are considered to increase the risk of heart diseases is it is recommended to keep the intake of this type of fat at a lower level.

Saturated fats could have some negative effects on the inflammatory pathway in the body.

Scientific study also shows the increase in inflammatory chemicals in the body due to increased saturated fats.

However, conclusive evidence for the same has not yet been established.

Unsaturated fatty acids are generally considered favorable to the human body. Omega-3 fatty acids are proven in the reduction of inflammatory responses in the body.

Omega-3 fatty acids are known to integrate into the cell membranes which can lead to lesser inflammation-causing chemicals thus reducing inflammation in the body.

Omega-6 fatty acids may benefit from reducing inflammation, but there are also some research data stating the contrary.

Therefore, conclusive evidence in this matter has not yet been strongly established.

Best Cooking Oils to Reduce Inflammation in Arthritis
