⚠️Important Safety Notes
Rule
Why It Matters
âť— Moderation is key
More than 1–1.5 oz/day may displace other foods or add excess calories
âť— Avoid salted or candied varieties
Added sugar/sodium reduces benefits
âť— Allergies exist
Tree nut allergies can be severe — do not consume if allergic
âť— Not for infants
Choking hazard — serve ground or as oil after age 1+
🚫 Never replace medical treatment with walnuts — they support health, but don’t cure disease.
