Macronutrient Profile of a 300g Russet Potato
A 300g raw russet potato, which includes the skin, provides a balanced and robust macronutrient profile, primarily consisting of carbohydrates, with a significant amount of dietary fiber.
- Carbohydrates: A 300g portion contains around 54 grams of total carbohydrates, with 48 grams being starch. Potatoes provide a high-quality source of energy and are a good fuel source for the body.
- Protein: This serving size provides approximately 6 grams of protein. The protein found in potatoes is considered high-quality due to its amino acid composition and digestibility.
- Fat: A 300g russet potato is naturally very low in fat, with only about 0.2 grams. It contains negligible amounts of saturated fat and is cholesterol-free.
Essential Micronutrients in 300g of Russet Potatoes
Beyond its macronutrient content, a russet potato is a powerhouse of essential vitamins and minerals, many of which are concentrated in the skin.
- Potassium: Containing over 1250mg, a 300g russet potato is an excellent source of this mineral, crucial for regulating blood pressure, fluid balance, and muscle function. This is significantly more than a medium-sized banana.
- Vitamin C: This portion provides around 17mg of Vitamin C, a powerful antioxidant that supports immune function, skin health, and collagen production.
- Vitamin B6: With about 1mg per 300g serving, russet potatoes are an excellent source of Vitamin B6, which is vital for protein metabolism and brain function.
- Iron: A 300g russet potato offers roughly 3mg of iron, which is important for transporting oxygen throughout the body.
- Magnesium: This serving provides approximately 69mg of magnesium, contributing to numerous bodily functions including nerve and muscle control and energy production.
- Fiber: Especially when consumed with the skin, a 300g russet potato provides a good source of dietary fiber, promoting healthy digestion and regularity.
The Impact of Cooking Method on Nutrition
The way a potato is prepared can significantly influence its final nutritional composition. While a raw 300g russet provides a solid baseline, different cooking methods, such as boiling or baking, impact nutrient retention and absorption.
- Boiling: This method can cause some water-soluble vitamins, like Vitamin C, to leach into the water. However, boiling can also increase the resistant starch content, which acts as a prebiotic and is beneficial for gut health. Boiled potatoes often have a lower glycemic index compared to baked ones.
- Baking: Baking concentrates the flavor and nutrients as the potato's water evaporates. This method generally preserves more Vitamin C than boiling and can increase resistant starch content. Baked potatoes tend to have a higher glycemic index than boiled ones.

| Iron | ~3 mg | ~3 mg |
Conclusion
In summary, a 300g russet potato, particularly when consumed with its skin, is a highly nutritious food, offering a rich supply of carbohydrates for energy, quality protein, and an impressive array of vitamins and minerals. The nutritional content, especially fiber and potassium, makes it a valuable component of a healthy, balanced diet. Opting for healthier cooking methods like baking or boiling over frying can help preserve its nutritional integrity, making it a satiating and beneficial choice for weight management and overall health.
