Scallops

Overview

Scallops are lean bivalve shellfish providing highly digestible protein, vitamin B12, selenium, zinc, and magnesium, together with animal-food sources of creatine and taurine that are emphasised in the BRAIN Diet protein rotation [1,2]. At roughly 66 kcal and 13.5 g protein per 100 g, they add mitochondrial-relevant amino compounds and micronutrient cofactors without the higher fat load of many red-meat or oily-fish portions [1].

Within the BRAIN Diet framework, scallops function as a lean marine protein alongside cod, tuna, and oily fish — useful when meals already contain adequate fat from olive oil, nuts, eggs, or dairy but still need complete protein and creatine-containing animal foods [1,3]. They complement plant-forward plates built around vegetables and whole grains, supporting bioenergetic cofactor sufficiency and phosphocreatine-buffer biology within BRS4 without dominating total energy intake [2,3].

Key Nutritional Highlights

• Lean shellfish (~66 kcal per 100 g) with 13.5 g protein and low fat — see nutrition table [1].
• Listed among BRAIN Diet creatine-containing animal foods alongside beef, lamb, pork, salmon, tuna, and cod [3].
• Shellfish such as scallops are commonly grouped with clams and mussels among dietary taurine sources in the framework [2].
• Provides vitamin B12 and selenium, supporting one-carbon and antioxidant enzyme contexts relevant to neural tissues [1,2].
• Complete, highly digestible animal protein with strong indispensable amino-acid coverage [1].

Food Context

Sourcing

• Choose scallops from reputable suppliers with transparent harvest or aquaculture practices and routine monitoring for biotoxins and contaminants.
• Wild sea scallops from well-managed fisheries can be a relatively low-impact seafood choice when sourced responsibly; check regional sustainability guidance where available.
• Like many lower-fat shellfish options, scallops are generally consumed as part of a varied seafood pattern rather than as a daily protein anchor.

Preparation

• Cook gently — light searing, steaming, or brief baking — to preserve texture and avoid toughening the protein.
• Pair with vegetable-rich sides and whole grains so lean shellfish protein, B12, and trace minerals sit within a balanced meal matrix.
• Avoid heavy charring or repeated high-heat frying that adds unnecessary oxidised fat load to an otherwise lean food.

Essential Amino Acid Profile

This food provides a complete essential amino acid profile typical of animal proteins, with high digestibility and bioavailability [1].

Source notes (supplementary):

• * Taurine: Taurine is a characteristic free amino sulfonic acid in Scallops; USDA SR Legacy does not include a taurine field.
• * Creatine: Creatine occurs in Scallops muscle/organ tissue; USDA SR Legacy does not report creatine.
