Health Considerations

While Omega-3 fatty acids are beneficial, there are a few health considerations to keep in mind:

• Mercury Levels: Pregnant women and young children should limit their intake of these fish.
• Allergies: Fish allergies are common. If you have a known allergy, avoid all fish and consult with a healthcare provider for alternatives.

Incorporating these fish into your diet can help you meet your Omega-3 needs, which are essential for heart health, brain function, and overall well-being. Aim to include a variety of these fish in your meals to maximize the health benefits associated with Omega-3 fatty acids.
