⚠️ Things to watch out for
🧂 1. Sodium (salt)
Some canned tuna can be high in salt → choose “low sodium” if needed.
🧪 2. Mercury content
- Tuna can contain small amounts of mercury
- Albacore (white tuna) usually has more than light tuna
- Eating in moderation is important, especially for pregnant women and children
🥫 3. Oil vs water
- Tuna in oil = more calories
- Tuna in water = lighter and lower fat
🟢 How often is it safe?
- Generally 2–3 servings per week is considered safe for most people (varies by type and diet)
💡 Bottom line
Tuna cans are a convenient, high-protein food, but like all canned fish, they’re best eaten in moderation due to mercury and salt content.
