From garlic-infused scampi to flavorful seafood boils, shrimp is a beloved shellfish choice—but is it actually good for your health? Known for its delicious taste, fast cooking time, and impressive nutritional profile, shrimp offers plenty of reasons to enjoy it. To understand more about the health benefits of shrimp, we reached out to an expert. So grab that cocktail sauce and join us as we explore shrimp's nutritional value.

Shrimp's Nutritional Profile

Shrimp is packed with essential vitamins and minerals, along with micronutrients like choline, phosphorus, copper, and B vitamins, such as niacin, B6, and B12. Here's a breakdown of the nutritional content in 3 ounces (about 85 grams) of raw shrimp.

• Water - 66.6 grams
• Calories - 72.2 kcal
• Protein - 17.1 grams (34.2% of the daily recommended value or DV)
• Fat - 0.433 grams
• Cholesterol - 137 milligrams
• Calcium - 54.4 milligrams (4.18% DV)
• Iron - 0.442 milligrams (2.46% DV)
• Magnesium - 29.8 milligrams (7.1% DV)
• Potassium - 224 milligrams (4.77% DV)
• Sodium - 101 milligrams
• Zinc - 1.14 milligrams (10.36% DV)
• Copper - 0.332 milligrams (36.89% DV)

Nutritional Benefits of Shrimp

If you needed more motivation to enjoy shrimp, here are some of the most significant health advantages of adding more of this shellfish to your diet.

1. Promotes Muscle Growth

A primary reason people often choose shrimp is that it’s an outstanding source of lean protein, thanks to its low levels of total and saturated fats. “Typically, 3 ounces of shrimp contains about 20 grams of protein,” explains clinical dietitian Tina Covone, MS, RD, CDN.

Protein serves as the building block for healthy muscles and plays a vital role in constructing nearly every tissue in the body. It also provides lasting energy, assists in the transport of oxygen throughout the body, and slows digestion to support better blood sugar control.

2. Supports Heart Health

Research has shown that regularly consuming shrimp is associated with a reduced risk of heart disease, even though it is a high-cholesterol food. “Studies on the dietary cholesterol in shrimp indicate it has little impact on blood cholesterol levels and heart disease risk,” says Covone.

Moreover, shrimp is packed with heart-healthy nutrients like unsaturated fats, omega-3 fatty acids, and the antioxidant astaxanthin. These unsaturated fats, including omega-3s, “boost HDL (good cholesterol) levels while lowering LDL (bad cholesterol) levels,” according to Covone.

Cholesterol levels in the blood are crucial in the development (or prevention) of heart disease. Astaxanthin helps regulate cholesterol similarly to omega-3s, providing additional anti-atherosclerotic benefits, which can reduce plaque build-up in arteries.

3. Enhances Thyroid Health

Shrimp is rich in iodine and selenium, two essential minerals for thyroid health. Iodine aids in thyroid hormone production, while selenium, found in large quantities in the thyroid, helps protect this vital organ. Selenium is often hard to find in natural foods, which makes shrimp an excellent source.

4. Boosts Immune System

Shrimp is also a great source of vitamin E and zinc, two antioxidants that combat free radical molecules. Vitamin E helps protect cells from oxidative stress by neutralizing harmful free radicals, thereby ensuring immune cells maintain their strength to better defend against infections.

Zinc, on the other hand, helps reduce inflammation by targeting free radicals. It also plays a role in the development and activation of immune cells, such as T-cells and macrophages, which are crucial for detecting and eliminating pathogens like viruses and bacteria.

5. Alleviates Inflammation

Astaxanthin, an antioxidant in shrimp, helps to reduce inflammation throughout the body. This supports your cells in fighting chronic conditions such as neurodegenerative diseases, cancer, and diabetes. By neutralizing free radicals and lowering oxidative stress, astaxanthin enhances anti-inflammatory cell activity and prevents the production of pro-inflammatory molecules like cytokines and COX-2 enzymes.

6. Promotes Eye Health

Astaxanthin, one of the key antioxidants in shrimp, helps protect the eyes from oxidative damage, potentially reducing the risk of age-related macular degeneration. Its unique molecular structure provides antioxidant, anti-inflammatory, and antiapoptotic (prevents cell death) effects, making it valuable in preventing and treating various eye disorders.

Research indicates that astaxanthin is effective in treating conditions such as retinal diseases, uveitis (eye inflammation), cataracts, and asthenopia (eye strain). It works by interacting with several metabolic pathways, helping to restore cellular balance. However, further long-term clinical trials are needed to determine the ideal dosage and delivery methods for astaxanthin.

Potential Risks of Eating Shrimp

Although shrimp offers numerous nutritional benefits, there are a few considerations when buying this seafood. Shrimp is one of the most common allergens, along with other shellfish.

There are also concerns about contamination in shrimp, including antibiotics, microplastics, and mercury. The US Food and Drug Administration (FDA) inspects only about 2% of the seafood imported into the country, meaning that chemicals used in large-scale shrimp farming, such as antibiotics, could remain. While mercury levels in shrimp are lower compared to larger fish like swordfish, tuna, and salmon, they can still accumulate in these shellfish.

In the US, up to 85% of seafood, including shrimp, is imported, with hundreds of millions of pounds entering the country every month. Much of this shrimp is produced through large-scale farming abroad, where high volumes of crustaceans are farmed at a very low cost. While the low price may be attractive, this type of shrimp farming comes with serious drawbacks, such as mangrove destruction, harmful fishing practices, and unethical labor conditions.
