Oysters are a very nutrient dense food, which means you get lots of nutrients for very little calories. Given the relative size of each oyster, they are packed full with essential nutrients, vitamins and minerals.

Calories: They are a low-calorie food! With only 68Kcal per 100g, you can indulge without feeling any of the guilt. With their high protein content also, this makes them a perfect food for those on a calorie-controlled diet. 68Kcal is only 3.5% of your total calories for a full day (for somebody on a 2,000Kcal calorie diet).

Protein: They are rich in high quality animal protein, which is essential for the growth and repair of all cells in the body. The protein content will help you to feel satiated and fuller for longer. Protein helps to build lean muscles, so oysters are ideal for those looking to lose bodyfat and build lean muscle.

Fat: Oysters are low in fat with only 2.5g of fat per 100g. You would have to eat kilos of oysters to eat more than the recommended fat intake for a person for a day!
