Glutamine

Glutamine is one of the amino acids that plays an important role in the functioning of many systems in the body, including the immune and digestive systems.

It is a conditionally essential amino acid, meaning that the body can synthesize it under certain conditions, but the demand for glutamine may increase during periods of stress or illness.

Functions of glutamine:

• Participation in protein synthesis.
• Maintenance of nitrogen balance in the body.
• Protection of the immune system and maintenance of intestinal barrier integrity.
• Regulation of glucose production.

Glutamine is particularly important for maintaining intestinal function, which is the largest organ of the immune system.

A glutamine deficiency can lead to disruptions in intestinal function and, consequently, to a deterioration in overall health.

Glutamine and the Keto Diet

Glutamine may be important on the keto diet as it can be involved in gluconeogenesis – the process by which glucose is synthesized from non-carbohydrate sources.

On the keto diet, this process provides glucose for tissues that cannot use ketones for energy, such as red blood cells.

It is important to note that while the keto diet reduces carbohydrate intake, it should not lead to a protein deficiency, including glutamine, which can come from food sources or supplements.

During the keto diet, it is important to maintain adequate protein intake to provide the body with necessary amino acids.

Foods Rich in Glutamine

To ensure an adequate amount of glutamine on the keto diet, it is recommended to consume protein-rich foods such as:

• meat (particularly poultry)
• fish
• eggs
• dairy products (low in carbohydrates)
• certain nuts and seeds

Thus, glutamine remains an important amino acid when following the keto diet, helping to support the immune system and intestinal health, as well as providing glucose for tissues that cannot use ketones.

A properly balanced keto diet should contain sufficient protein to prevent a glutamine deficiency.
