Tuna is especially rich in EPA and DHA, which are directly related to numerous health benefits.
Protein Content in Tuna
Proteins are macronutrients necessary for the growth, repair and maintenance of body tissues. They are formed by amino acids, which are the basic components of proteins. Tuna is an excellent source of high quality proteins, so it is an ideal option for those who wish to increase their protein intake.
Protein Content in Tuna Varieties
Tuna occurs in several species, and protein content can vary slightly from one to another. The approximate protein content of the different types of tuna is broken down:
- Yellow fin tuna: yellow fin tuna is known for its soft flavor and tender texture. It is a lean fish that contains approximately 25 grams of proteins per 100 grams.
- White tuna: White tuna, also known as the North Bonito, is rich in omega-3 fatty acids and proteins. It contains about 23 grams of proteins per 100 grams.
- Patudo: The patudo is a kind of larger with a rich and fleshy flavor. It offers about 24 grams of proteins per 100 grams.
These figures are approximate and may vary depending on the specific type of tuna and its preparation method. It should be noted that fresh tuna usually has a higher protein content than canned tuna, due to the removal of water during the canning process.
Important note: Protein is an essential nutrient for the body, and incorporating tuna into your diet can help you meet your protein needs. However, it is important to consume tuna in moderation, as it may contain mercury, especially in larger species. Consult a healthcare professional or nutritionist for personalized dietary advice.
Omega-3 Fatty Acid Benefits of Tuna
Omega-3 fatty acids are a type of polyunsaturated fat that the body does not produce and must be obtained from dietary sources. Tuna is an excellent source of two important omega-3 fatty acids: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These fatty acids have been widely studied for their numerous health benefits.
The benefits of omega-3 fatty acids in tuna include:
-
Reducing the risk of heart disease: Omega-3 fatty acids help lower triglyceride levels, reduce blood pressure and prevent the formation of blood clots. These effects help reduce the risk of heart disease and improve overall cardiovascular health.
-
Anti-inflammatory properties: EPA and DHA have anti-inflammatory effects on the body, which can help relieve symptoms of inflammatory conditions such as arthritis. Additionally, these fatty acids can reduce the production of inflammatory compounds, thereby reducing the risk of chronic diseases related to inflammation.
-
Brain Health: DHA is a major component of brain tissue and is essential for proper brain function. Consumption of omega-3 fatty acids from tuna can support cognitive function, improve memory and reduce the risk of age-related cognitive decline and neurodegenerative diseases such as Alzheimer’s.
“Including tuna in the diet can provide a number of health benefits due to its omega-3 fatty acid content. These benefits include reducing the risk of neurodegenerative diseases. These benefits include a lower risk of heart disease, anti-inflammatory effects and better brain health.
It is important to note that the omega-3 fatty acid content and benefits of tuna can vary depending on the type and quality of the fish, as well as the cooking method.
