Seafood is one of the most nutritious food groups you can eat, especially as you age. It’s rich in omega-3 fatty acids, high-quality protein, and essential vitamins. But not all seafood is created equal. Some types are high in mercury or contaminants, while others are packed with nutrients and low in toxins. Here are the best and worst seafood choices for seniors.
The BEST Seafood Choices for Seniors
1. Wild-Caught Salmon
Rich in omega-3s, vitamin D, and selenium. It supports heart health, brain function, and joint mobility. Aim for two servings per week.
2. Sardines
Small, low on the food chain, and packed with omega-3s, calcium, and vitamin D. They are one of the safest and most nutrient-dense fish you can eat.
3. Atlantic Mackerel
Not to be confused with king mackerel. Atlantic mackerel is high in omega-3s and low in mercury. It’s also rich in selenium and vitamin B12.
4. Rainbow Trout
A lean, mild-flavored fish that is easy to digest. It provides high-quality protein and selenium, which supports kidney health.
5. Anchovies
Tiny, flavorful fish packed with omega-3s and calcium. They are low in mercury and can be used in sauces, salads, and spreads.
6. Oysters
Rich in zinc, which supports immune function and wound healing. They also provide vitamin B12 and omega-3s.
7. Mussels
Packed with protein, iron, and vitamin B12. They are sustainably farmed and low in contaminants.
8. Clams
Excellent source of iron and vitamin B12. They are low in mercury and rich in antioxidants.
The WORST Seafood Choices for Seniors
1. Swordfish
Very high in mercury. Regular consumption can damage the nervous system and kidneys. Avoid entirely.
2. King Mackerel
Extremely high in mercury. Not the same as Atlantic mackerel. Should be strictly avoided.
3. Tilefish (Gulf of Mexico)
Among the highest mercury levels of any fish. The FDA advises older adults to avoid it entirely.
4. Shark
High in mercury and other heavy metals. Also contains urea, which can be hard on the kidneys.
5. Bigeye Tuna
Higher in mercury than other tuna varieties. Limit consumption or choose skipjack or albacore instead.
6. Orange Roughy
A deep-sea fish that can live for over 100 years, accumulating high levels of mercury and other contaminants over its lifetime.
7. Marlin
High in mercury and not recommended for regular consumption.
8. Imported Farmed Shrimp (from unregulated sources)
May contain antibiotics, pesticides, and other contaminants. Choose wild-caught or responsibly farmed shrimp instead.
How to Choose Safe Seafood
- Choose smaller fish. They accumulate fewer toxins.
- Look for wild-caught options. They generally have a better nutrient profile.
- Check sustainability certifications. MSC (Marine Stewardship Council) certification ensures responsible fishing practices.
- Vary your choices. Eating a variety of seafood reduces the risk of overexposure to any single contaminant.
- Limit high-mercury fish. Avoid the worst choices listed above.
A Gentle Reminder
Seafood is a wonderful source of nutrition for seniors when chosen wisely. By selecting the best options and avoiding the worst, you can support your heart, brain, and overall health. Your body will thank you for making informed choices.
