Shrimps, Prawns, Langoustines are nutritional gold. Particularly for people who suffer from sulfites sensitivity or MSG allergies, as they are rich in B Vitamins, including B12 and niacin.
Shrimps are very high in Omega 3 fats, are an excellent source of lean protein and are also high in phosphorous, zinc and iron. They are very low in calories and will fill you up thanks to their high protein load
Even more important in the cloudy climes of Britain, shellfish are incredibly high in Vitamin D.
Defeciencies in Vitamin D can produce depression, auto-immune disorders, osteoporosis and hypertension. A serving of shrimp (4 oz or 120gm) contains as much Vitamin D as a glass of milk. Which is brilliant for those of us who are dairy free.
To top it all off, shellfish are low in mercury.
Calories – only about 1 per gram. So a 120g serving of shellfish is only about 120 calories but packs a nutritional punch.
