Unpacking the “Bonito Potato” Confusion
The phrase "bonito potato" is a classic food misnomer, resulting from the phonetic similarity between boniato (a type of sweet potato) and bonito (a fish). It’s important to distinguish between these two food items to understand their respective calorie counts and nutritional profiles. The boniato, a tropical root vegetable with dry, white flesh and purplish skin, is botanically a type of sweet potato. In contrast, bonito is a medium-sized predatory fish related to tuna, prized for its flavorful meat.
A Detailed Look at Boniato Nutrition and Calories
For those interested in the vegetable, here's a closer look at the calories in a boniato potato. The calorie content can vary slightly depending on preparation and size, but general figures are available:
- Per 100g (raw): A 100-gram serving of raw boniato contains approximately 86 calories. This serving provides about 20g of carbohydrates and 1.6g of protein, with negligible fat.
- Per Medium Potato (180g): A medium-sized boniato contains roughly 155 calories.
- Other serving sizes: A larger boniato of 400g can have around 242 calories.
Boniato is rich in complex carbohydrates, making it an excellent source of sustained energy. It's also known for its fiber content, which promotes digestive health and satiety, and is a good source of vitamins C and A, as well as minerals like potassium. Its resistant starch content helps stabilize blood sugar levels, making it a favorable option for athletes or individuals monitoring glucose intake.
How Cooking Methods Impact Boniato Calories
The way you prepare a boniato significantly influences its final calorie count. For the lowest calorie option, boiling or steaming is best. Adding extra ingredients, however, will increase the energy value:
- Roasting or Baking: These methods add no extra calories, assuming you don't use oils or butter.
- Frying: Deep-frying boniato to make chips or fries adds a substantial amount of fat and calories from the cooking oil.
- Mashing: Mashing the boniato with high-calorie additions like butter, cream, or coconut milk will boost the total calorie count.
The Calorie Count for Bonito (The Fish)
Bonito is an oily fish packed with protein and omega-3 fatty acids, but with no carbohydrates. Here's a summary of its calorie information:
- Per 100g (cooked): Bonito fish contains roughly 103 to 139 calories per 100g, depending on the species and cooking method. It is an excellent source of protein, with about 22g per 100g serving.
- Per Medium Fillet (120g): A medium fillet contains approximately 124 calories.
- Bonito Flakes (Katsuobushi): These dried, shaved bonito flakes, used often in Japanese cuisine, are very low in calories, with only about 10 calories per serving.
Like other fatty fish, bonito is a great source of omega-3s, which are essential for cardiovascular and brain health. It also contains B vitamins and minerals like iron, phosphorus, and potassium.

Choosing the Right Ingredient for Your Needs
When deciding between boniato and bonito, your dietary goals are key. If you are seeking a high-fiber, vitamin-rich carbohydrate source, the boniato is the clear choice. Its resistant starch provides sustained energy and can aid in blood sugar management. Conversely, if your goal is high protein and healthy fats like omega-3s, bonito fish is a superior option. For example, it is a valuable addition to a heart-healthy diet.
Another factor is the culinary role. Boniato is versatile for use in savory and sweet potato recipes, from mashed dishes to fries. Bonito fish is excellent for grilling, searing, or as a flavor-rich ingredient in broths (katsuobushi). Making your choice depends entirely on the flavors and nutritional composition you seek for your meal. Whether you opt for a high-energy vegetable or a protein-rich fish, understanding the distinct nutritional value of each allows for informed and healthy food choices.
