Why does your body need protein?
Amino acids are the building blocks your body needs for practically all kinds of operations. Protein is essential for everything from rebuilding muscle following exercise to creating digestive enzymes to generating hormones controlling your metabolism and mood.
The following are some main arguments for the need for enough protein:
- Muscle Development and Healing: Your muscles require protein to heal and get stronger following any physical activity, but especially strength training.
- Antibodies: Used to combat infections are derived from proteins.
- Strong nails, hair, and skin: Dietary protein is essential for proteins that give skin suppleness and hair strength—collagen and keratin.
- Production of many hormones, including insulin, depends on protein structures.
- Protein supports sensible weight reduction by helping you feel full longer, thereby lowering overeating.
The National Institutes of Health (NIH) estimates that for protein, the recommended dietary allowance (RDA) is about 0.8 grams per kilogram of body weight. For older adults seeking to maintain muscle mass, athletes, or active adults, however, protein needs are more between 1.2 and 2.0 grams per kilogram.
Why Fish Are Such Excellent Sources of Protein?
Fish provides numerous other health advantages in addition to being high in protein:
- Fish is a “complete protein” source as it boasts all nine essential amino acids your body cannot create on its own.
- Most fish are lean proteins; hence, they offer protein without too many calories or bad fats.
- Many fish, particularly fatty varieties like salmon and sardines, are high in EPA and DHA omega-3s, which benefit heart and brain function.
- Fish supplies vital minerals and vitamins, including B vitamins, selenium, iodine, and vitamin D.
- Regular fish intake has been associated with lower rates of depression, better cognitive function, and even decreased chances of heart disease.
