The Health Benefits of Eating Seafood Daily

1. Rich in Omega-3 Fatty Acids (Heart & Brain Health)

Omega-3s (EPA and DHA) are crucial for:

• Reducing inflammation (lowering risk of heart disease)
• Supporting brain function (may help prevent cognitive decline)
• Improving mood (linked to reduced depression risk)

Best sources: Salmon, mackerel, sardines, herring, anchovies

2. High-Quality Protein (Muscle Growth & Repair)

Seafood provides complete protein (all essential amino acids) with fewer calories than red meat. Benefits include:

• Faster muscle recovery
• Better metabolism support
• Lower risk of obesity

3. Essential Vitamins & Minerals

• Vitamin D (Supports bone health & immunity)
• Vitamin B12 (Critical for nerve function & energy)
• Iodine (Necessary for thyroid function)
• Selenium (Powerful antioxidant)

4. Low in Saturated Fat (Heart-Healthy Choice)

Unlike fatty cuts of red meat, most seafood is low in unhealthy fats, making it ideal for cardiovascular health.

Potential Risks of Eating Seafood Every Day

1. Mercury Poisoning (Biggest Concern)

Some fish accumulate high levels of methylmercury, a neurotoxin that can harm the nervous system over time.

🚫 High-mercury fish to avoid or limit:

• Shark
• Swordfish
• King mackerel
• Tilefish
• Bigeye tuna

2. Environmental Contaminants (PCBs, Microplastics, Antibiotics)

Farmed fish (especially from unregulated sources) may contain:

• PCBs (industrial pollutants)
• Antibiotics (overused in some aquaculture)
• Microplastics (from ocean pollution)

3. Allergies & Overconsumption Risks

• Shellfish allergies are common and can be severe.
• Excessive iodine (from too much seafood) may disrupt thyroid function.
