WHO SHOULD AVOID OR LIMIT THESE FISH?

While these fish are nutritious, some individuals must be cautious.

1. Pregnant Women and Children (Certain Species Only)

They should avoid or strictly limit:

  • Large tuna (albacore)
  • King mackerel
  • Certain catfish from polluted waters

Because of mercury sensitivity, the developing brain is extremely vulnerable.

Safe options: anchovies, sardines, cod, light tuna.

2. People With Seafood Allergies

Even mild fish allergies can escalate into life-threatening reactions. Symptoms may include:

  • Hives
  • Swelling

These individuals should avoid fish entirely unless medically supervised.

3. Individuals With Gout or High Uric Acid

Fish contains purines. Excessive intake can worsen:

Low-purine fish like cod and catfish are safer options, but consumption should still be limited.

4. People Taking Blood-Thinning Medication

Omega-3 can naturally thin the blood. Combined with medications such as:

Moderation is essential.

5. Those With Kidney Disease

High-protein foods, including fish, can stress weakened kidneys.
They should consult a nephrologist before increasing fish intake.
