According to the American Journal Of Clinical Nutrition, there is a link between your protein intake, satiety, and weight management (2). A study conducted by the University of Copenhagen, Denmark, on 1209 adults found that diets rich in protein help with weight loss (3). Incorporating seafood as a part of a nutritionally balanced energy-restricted diet helps boost weight loss (4). In addition, the fewer calories and higher protein content of scallops help prevent excess fat and maintain lean body mass (5).

2. Promote Heart Health

Dietary intake of cod and scallops may help reduce atherosclerotic (build-up of fats in artery walls) plaque (6). Scallops are low in saturated fat and their daily intake helps decrease the risk of cardiovascular disease (7). In addition, the potassium and magnesium in scallops help treat hypertension (8). Several studies have shown that magnesium deficiency is linked with heart problems (9), (10).

3. Help Improve Nervous System Function

Animal studies conclude that administration of plasmalogens, which are derived from scallops, helps improve cognitive function in people with mild Alzheimer’s disease and cognitive impairment (11). Also, the presence of B vitamins (like vitamin B12) in scallops helps lower homocysteine and improve brain health (high homocysteine levels are linked with cognitive impairment) (12), (13). In addition, seafood is high in omega-3 fats that help improve brain function (14).

4. Help Strengthen Bones

The protein scallops may help reduce hip fracture risks and improve bone health. A review published in the Computational and Structural Biotechnology Journal suggests that high protein intake plays a key role in maintaining bone mineral densityi  The amount of minerals (dominantly phosphorus and calcium) present in bone tissues that are important for healthy bones and prevent bone loss. (BMD) in older adults (15). However, more studies are warranted to understand this phenomenon of scallops.

5. Support A Healthy Pregnancy

In some cases, people may experience anaphylactic shocki  An allergic reaction that causes the release of chemicals in the body which lead to a sudden drop in blood pressure, resulting in shock. .

  •  Place an oyster shucking knife at the hinge and prize it open slightly.
  •  Turn the scallop over and run a flexible fish filleting knife over the flat side of the shell to release the scallop.
  •  Open the shell fully. Use a spoon to release the scallop from the bottom shell.
  •  Discard the frill, the black stomach sack, and any other pieces that are around the meat of the scallop. You would be left with just the white flesh.
  •  Rinse the scallop thoroughly in cold water.

Emily, a food blogger, shares her experience of cooking scallops in different ways: “I grew up on frozen scallops from Costco and thought I loved scallops then. My first fresh diver scallop (from the mussels lady at the Santa Barbara Farmers Market, sold fresh in the shell) made me realize what a fool I’d been (i).” Referring to the use of celery root in one of her recipes, she observes, “The celery root purée was the perfect complement to the scallops, yet was mild enough not to stand in the way of appreciating how awesome the scallops taste on their own. This cooking method is by far my favorite way that I’ve ever prepared scallops.”
