Why Choose Seafood for Protein?
Seafood is an excellent source of high-quality, easily digestible protein, making it a valuable part of any diet. Unlike red meat and poultry, many types of seafood are lower in saturated fat while still providing all nine essential amino acids needed for muscle repair, growth, and other vital bodily functions. Beyond protein, seafood provides a host of other nutrients, including heart-healthy omega-3 fatty acids, vitamin D, vitamin B12, selenium, and iron. This combination of protein and micronutrients supports everything from immune function to brain health.
