Health Benefits of Tuna Fish
Incorporating tuna into your diet can offer numerous health benefits. Here are some of the key reasons why tuna fish is healthy:
- Supports Heart Health: The omega-3 fatty acids in tuna help reduce inflammation, lower triglyceride levels, and improve cholesterol profiles, all of which contribute to a healthier heart. Regular consumption of tuna can reduce the risk of heart disease and stroke.
- Promotes Brain Health: Omega-3s, particularly DHA, are crucial for brain health. They support cognitive function, improve memory, and may reduce the risk of neurodegenerative diseases like Alzheimer’s.
