✅ Proven Benefits:

• Enhances fetal brain development during pregnancy (Dr. Michael Crawford, Brain Institute – London).
• Reduces the risk of Alzheimer’s disease and dementia by up to 35%, as shown in a 2022 Journal of Neurology study.

Children who consume fish regularly have a 24% lower chance of developing asthma, according to a Dutch study from Maastricht University.

✅ Core Benefit: Omega-3 helps reduce inflammation in the respiratory airways and strengthens the immune system.

6. Supporting Diabetes Management

Fish is an excellent choice for individuals with type 2 diabetes, helping to:

• Improve insulin sensitivity
• Regulate blood sugar levels
