Is Eating Shrimp Healthy or Harmful? Here’s What You Need to Know

Shrimp is the most popular seafood in the United States, beloved for its versatility and flavor. But concerns over contaminants, cholesterol, and sustainability may leave you wondering: Is shrimp healthy or harmful?

Let’s break down the risks, benefits, and tips for enjoying shrimp safely and responsibly.

The Risks of Eating Shrimp

Like all animal-based foods, shrimp comes with some health and environmental concerns.

1. Shrimp Is High in Cholesterol
A 3-ounce serving of shrimp contains 180 milligrams of cholesterol more than double the amount in the same portion of ground beef. However, recent research suggests that dietary cholesterol has less impact on blood cholesterol than saturated and trans fats. Shrimp, with just 0.4 grams of saturated fat per serving, is unlikely to pose significant risks for most people.

2. Shrimp May Contain Contaminants

• Mercury: Shrimp contains trace amounts of mercury, but levels are low enough to be considered safe for most people, including pregnant individuals.

• Antibiotics: Farmed shrimp may be treated with antibiotics, which can leave residue. While the FDA monitors imports, not all shipments are screened, meaning some antibiotics could slip through.

3. Shrimp Is a Common Allergen
Shellfish allergies are among the most common food allergies, affecting an estimated 7 million Americans. Symptoms can range from hives to life-threatening anaphylaxis.

The Health Benefits of Shrimp

Despite its risks, shrimp offers impressive nutritional benefits:

1. Low in Calories, High in Protein
Shrimp delivers nearly 20 grams of protein per 3-ounce serving with just 101 calories, making it a filling and lean protein source.

2. Contains Omega-3 Fatty Acids
Shrimp provides 0.25 grams of omega-3s per serving. While not as rich in omega-3s as fatty fish like salmon, shrimp can still support brain and heart health.

3. Rich in Antioxidants
Shrimp is a good source of astaxanthin, an antioxidant linked to reduced risk of heart disease and protection against skin damage.

4. Low Mercury Levels
Shrimp is considered one of the safest seafood options regarding mercury, with levels far below the tolerable intake threshold.

How to Pick Quality Shrimp

Whether you choose wild-caught or farmed shrimp, follow these tips to ensure quality and sustainability:

• Look for Certifications: Check the packaging or consult Seafood Watch for shrimp harvested using sustainable practices.

• Buy Frozen When Possible: Unless you live near the coast, frozen shrimp is often fresher than “fresh” shrimp that may have been previously frozen.

• Avoid Refrozen Shrimp: Watch for large ice crystals, which can indicate thawing and refreezing.

Is Shrimp Bad for You?

For most people, shrimp is a healthy choice and fits well into a balanced diet. It’s rich in protein, low in calories, and packed with essential nutrients like selenium, vitamin B12, and antioxidants.

However, those with high cholesterol, LDL levels, or shellfish allergies should approach shrimp cautiously.

The Bottom Line

Shrimp can be a delicious and nutrient-dense addition to your plate. To enjoy it safely:

• Focus on portion sizes (two to three servings per week is ideal).

• Pair shrimp with heart-healthy sides like leafy greens or whole grains.

• Opt for high-quality, sustainable shrimp whenever possible.
