Benefits of shellfish. For ages, people have been eating shellfish all across the world. They are abundant in minerals, healthy fats, and lean protein. Eating shellfish on a regular basis may help you lose weight, strengthen your heart and brain, and increase your immunity. However, some varieties of shellfish may include heavy metals and pollutants, making them one of the most prevalent dietary allergies.
BENEFITS OF SHELLFISH
Animals with a shell or shell-like exterior that live in water are known as shellfish. They fall into two categories: mollusks and crustaceans. Mollusks include clams, scallops, oysters, and mussels, whereas crustaceans include shrimp, crayfish, crab, and lobster.
1. Encourage Weight Loss

Shellfish are great meals to eat when attempting to lose weight since they are low in calories and high in lean protein and healthy fats. Foods high in protein help you feel full and content, which may limit you from consuming too many calories and aid in weight loss or maintenance. Furthermore, compared to other high-protein diets, fish may promote greater sensations of fullness and aid in weight loss because of their omega-3 fatty acid content.
2. Encourage the Health of Your Heart
Numerous minerals included in shellfish, such as vitamin B12 and omega-3 fatty acids, may support heart health.
Eating fish and shellfish that contain omega-3 fatty acids has been associated in several studies with a decreased risk of heart disease. Omega-3s’ anti-inflammatory properties are probably the reason for this. A substance called homocysteine, which raises the risk of heart disease, has also been connected to high blood levels of vitamin B12 deficiency. Consequently, consuming vitamin B12-rich foods may help prevent heart disease.
3. Beneficial to Your Brain

Shellfish contains heart-healthy elements that are also essential for cognitive function.
In fact, low blood levels of omega-3 and vitamin B12 have been linked in a number of studies to problems with both healthy adult brain function and child brain development. Additionally, some studies indicate that omega-3 fatty acids and vitamin B12 may work in concert to support brain health.
4. Rich in Nutrients That Boost the Immune System

Certain kinds of shellfish are rich in zinc, which strengthens the immune system. The development of the cells that comprise your body’s immunological system depends on this mineral. Additionally, it protects against inflammation-induced damage by acting as an antioxidant. According to one study, zinc deficiency was linked to a decrease in the activity of specific immune cells in 62 healthy persons over 90.
Side effects
1. Accumulation of Heavy Metals
However, shellfish have the potential to absorb heavy metals like cadmium or mercury from their surroundings. Heavy metals cannot be eliminated by humans. These substances can accumulate in your body over time, causing organ damage and other health problems.
2. Foodborne Disease

Also, a foodborne illness may result from consuming tainted shellfish. Raw seafood and improperly refrigerated shellfish are breeding grounds for pathogens. Consequently, shellfish can be effectively stored and cooked to reduce the risk of foodborne illness. Bacteria, viruses, or parasites that are acquired from their surroundings can cause food poisoning in shellfish.
Summary
Lean protein, good fats, and micronutrients abound in shellfish, which are classified as crustaceans and mollusks.
For the healthiest individuals, however, shellfish can be a tasty and nourishing supplement to a well-balanced diet.
