Shrimps are the most frequently eaten among the varieties of shellfish. It is highly nutrient-dense and offers significant nutrients, including iodine, which are rare in many other foods. Yet, because of its high cholesterol level, some contend that shrimp is harmful. Also, it’s generally accepted that shrimp farmed on farms may be less healthy than shrimp harvested in the wild.

10 Benefits of Shrimps

1. Weight Loss

Shrimps have few calories but a lot of protein and other nutrients. Eating foods high in protein and nutrient-dense is constantly suggested to lose weight and keep a healthy, lean body mass.

2. Eye Health

Astaxanthin has proven to be essential in preserving excellent eye health, including guarding the retina against oxidative damage, particularly from prolonged exposure to sunshine. In addition, according to preliminary research, astaxanthin may help solve problems affecting the centre of the eye when combined with other nutrients.

3. Bone Strength

Both phosphorous and vitamin D are found in shrimps and shellfish. Working with calcium, the supplied nutrients can help strengthen bones, subsequently lessening the risk of bone fractures and osteoporosis later.

4. Enhancer of Mood and Brain Health

Tryptophan, a substance found in shrimps, is suggested to stimulate the release of the mood-enhancing hormone serotonin. In addition, shrimp’s omega-3 and vitamin B12 concentration may help maintain brain health, keep it awake and bright, and fight against Alzheimer’s disease.

5. Prevents Cancer

Astaxanthin and omega-3 fatty acids have powerful antioxidant capabilities that may have preventive and inhibitory effects on Cancer, slowing the spread of cancerous cells. Fascinatingly, in addition to eating shrimps, scientists are now examining their extraordinary eyesight for hints in cancer diagnosis.

6. Skin Protection

Supplementing with astaxanthin helps lessen skin wrinkling by enhancing skin elasticity and hydration, in addition to sunscreen and other skin-protection measures. Moreover, astaxanthin can diminish skin cancer risk by minimising UV-induced skin damage.

7. Protection Against Heart Disease

Although concerns about eating shrimp have been raised because of its high cholesterol level, study shows there is no downside to enjoying this popular seafood. Due to the omega-3 fatty acids included in shrimps, it has been demonstrated that eating shrimp can lower levels of LDL (the “bad”) cholesterol and triglycerides while increasing levels of HDL (the “good”) cholesterol. Omega-3 fatty acids, which play a crucial role in heart health and have anti-inflammatory qualities, are another nutrient in shrimp.

A study published in the Mayo Clinic Proceedings found a positive correlation between shrimps consumption and better lipid panels; eating shrimps is associated with a decreased risk of heart disease than not eating shrimp.

8. Women’s Health

Shrimp is an important meal that can improve the health of women. The menopausal symptoms of moodiness, joint discomfort, and hot flashes have been demonstrated to be reduced by astaxanthin. Premenstrual syndrome, popularly known as PMS, is characterised by mood swings, sensitive breasts, food cravings, exhaustion, irritability, and sadness. Omega-3 fatty acids may help to reduce these symptoms.

According to the U.S. Food and Drug Administration’s “Information About Fish” publication, shrimp is among the “best choices” of fish for young children and women who are trying to get pregnant, pregnant, or nursing.

9. A trustworthy protein source

Amazingly, 3 ounces of cooked shrimp contain 20 grams of protein, 40% of the daily required intake. Also, this has 84 calories. Shrimp’s protein can help you feel fuller for longer, which is beneficial for managing your weight and supporting physical activity.

10. An excellent mineral source.

The nutrients that shrimp contains are primarily responsible for its many health advantages. According to a registered dietitian, shrimp is a flexible, low-calorie shellfish with iodine, phosphorus, zinc, and magnesium. These minerals are crucial for a variety of causes. For example, magnesium is excellent for everything from bone health to immunity, while zinc is great for both.

Potential Negative Effects

1. May Result in Allergic Reactions

Shrimp’s muscle protein, tropomyosin, is thought to trigger allergic responses in many people. The most typical symptoms are lip swelling and throat and mouth itching.

Up to 10.3% of the general population suffers from shellfish allergy. According to a study based on Electronic Health Records in the U.S., peanuts (0.5%) and shellfish (0.9%) were the two foods that caused the most food allergies.

2. May Have High Metal Contamination

Because they are bottom feeders, shrimp are prone to collecting heavy metals in a contaminated environment. As a result, issues regarding the presence of mercury and other heavy metals in shrimp have been brought up.

Nonetheless, most of the shrimp we consume are grown on farms where their diets and environments are continuously controlled. Hence, there is a minimal likelihood of mercury contamination in shrimp. To be safe, though, try to balance your shrimp consumption.

Tips for Consuming

The following advice will help you consume shrimp safely and avoid getting food poisoning:

Buy only frozen shrimp displayed in a case or covered with a thick layer of new ice. The shrimp should have minimal to no odour and be transparent and pearl-like.

It’s essential to remember that frozen shrimp can go bad if it defrosts during shipping or is kept in heated conditions for too long before being cooked.

Sauté shrimp until they reach an internal temperature of 145°F. In the absence of a food thermometer, make sure the meat is clear and solid.

The most crucial preparation advice is to stay away from frying to enhance heart benefits. Instead, add shrimp that has been steamed or boiled to many recipes, including soups, salads, tacos, and stir-fries. Use avocado oil, which is heart-healthy, to grill or sauté shrimp. Then serve it with many vegetables and a nutritious starch, such as corn, sweet potato, brown or wild rice. Many spices can be used along with shrimps like lemon, pepper, chili, lime, garlic, paprika, cumin, cilantro, mint, ginger, and turmeric, can be used to season shrimp because of their adaptability.


Both benefits and drawbacks of eating shrimp exist. It offers essential minerals and lean protein, which may protect your health. But shrimp could be contaminated or should be avoided if you have a food allergy. If you prefer shrimp and are not allergic to it, consume it in moderation to reduce exposure to possible toxins. Moreover, you can pick seafood such as salmon, sardines, mackerel, and trout that are higher in health-protective omega-3 fatty acids and lower in mercury than shrimps. Finally, speak with your healthcare physician about how shrimp fits your specific health objectives if you have heart disease, are worried about mercury, other pollutants, or other conditions.
