Nutritionist’s View: Health Benefits and Tips
Dining at Sumo Japanese Restaurant can be very healthy if guests make mindful choices.
Health Benefits of the Menu
-
Omega-3 and Pure Protein: The Sashimi section (fish without rice) is the gold standard for heart health. Salmon, Tuna, and Yellowtail are rich in Omega-3 fatty acids, which reduce inflammation and support brain function.
-
Probiotics: Traditional Miso Soup contains fermented paste, which acts as a probiotic to support gut health.
-
Fiber: Appetizers like Edamame (steamed soybeans) and Seaweed Salad provide essential fiber and iodine.
-
Cooking Method: Hibachi cooking (flash searing) retains more vitamins in vegetables and meat compared to deep-frying.
What to Watch Out For (Dietary Restrictions)
To maintain a balanced diet, guests should consider the following:
- Sauces: Rolls labeled “Spicy” or “Dynamite” often contain mayonnaise, while Eel sauce is high in sugar. It is recommended to ask for sauces “on the side” to control the portion.
- Deep-Fried Items: Dishes labeled “Tempura” are battered and fried, which increases calorie content.
- Carbohydrates: Bento boxes come with large portions of white rice. For a lighter meal, guests can ask to substitute rice with extra vegetables or choose brown rice if available.
