About Tuna chunks
Tuna chunks are derived from various species of tuna, such as skipjack or albacore, commonly used in cuisines worldwide. Popular in salads, sandwiches, and casseroles, tuna is especially prominent in Mediterranean and Japanese dishes. Nutritionally, tuna is a lean protein source rich in omega-3 fatty acids, essential vitamins like B12 and D, and minerals such as selenium and phosphorus. It’s also low in saturated fat and provides approximately 25 grams of protein per 100 grams, making it a highly nutritious option for those seeking balanced macronutrients. However, mercury content should be considered, especially for pregnant women and young children.
