Key Nutritional Breakdown (Per 100g Cooked/Grilled Fillet)
According to the USDA FoodData Central nutrient profiles, a 100-gram serving of seasoned, grilled eel averages:
- Calories: ~285 to 310 kcal (Highly energetic and filling)
- Protein: ~23.6 g (Rich in tissue-repairing essential amino acids)

- Carbohydrates: ~5g to 15g (Varies depending on how heavily the sweet teriyaki glaze is applied)
Core Health Benefits
- Unmatched Vitamin A Density: A single 100g serving of eel completely satisfies over 120% of your daily Vitamin A requirement. This fat-soluble vitamin plays an essential role in optimizing night vision, boosting white blood cell immunity, and promoting radiant skin cellular turnover.
- Massive Omega-3 Yield: Eels contain significantly higher concentrations of DHA and EPA than many other commercial fish species. These liquid lipids have non-solidifying properties that help lower blood pressure, reduce arterial plaque, and enhance cognitive memory functions.
- Immune & Bone Regulators: It is an excellent natural food source for Vitamin D and Vitamin E. This combination enhances calcium absorption to prevent osteoporosis while acting as a cellular antioxidant to slow downward signs of aging.
- Stamina & Recovery Tradition: In Asian food culture, eating grilled eel is a famous remedy to beat summer fatigue (Doyo no Ushi in Japan) and replenish internal Qi and blood flow.
Direct Dietary Considerations
While grilled eel is highly nutritious, the primary downside comes from the sweet kabayaki basting sauce, which adds hidden sugars and a high amount of sodium. If you are actively managing your glycemic index or blood pressure, look for Shirayaki—which is eel grilled purely with salt and zero sugary sauces.
