Calories and Nutritional Breakdown of 100g Roasted Soybeans
On average, 100g of mature, dry roasted soybeans contains around 451 calories. The exact number can vary slightly based on preparation, such as whether oil or salt is added. This high calorie count is due to its dense concentration of macronutrients, particularly protein and healthy fats. This makes it an energy-dense food, perfect for feeling full and sustaining energy levels.
Macronutrient Profile
A 100g serving of dry roasted soybeans packs a powerful punch of protein, fat, and carbohydrates.
- Protein: With approximately 40 grams of high-quality protein, roasted soybeans are an excellent source for muscle repair and growth, especially for those on a vegetarian or vegan diet.
- Fat: The fat content is around 22 grams, consisting primarily of healthy polyunsaturated fats. These fats are crucial for brain function and overall health.
- Carbohydrates: There are roughly 33 grams of carbohydrates in 100g, with a substantial portion coming from dietary fiber. This helps with digestion and promotes a feeling of fullness.
Vitamin and Mineral Content
Beyond the macronutrients, roasted soybeans are a rich source of vital vitamins and minerals.
- Minerals: They are high in iron, calcium, magnesium, phosphorus, and zinc. These minerals are essential for bone health, immune function, and carrying oxygen in the blood.
- Vitamins: A good source of B vitamins, especially folate (Vitamin B9), which is important for cell growth and metabolism. Roasted soybeans also contain Vitamin K, which is vital for blood clotting.
The Impact of Roasting on Nutritional Value
Roasting soybeans has several positive effects on their nutritional profile and digestion.
- Increased Digestibility: The heat from roasting breaks down the beans' cell walls and denatures proteins, making the nutrients easier for the body to absorb.
- Reduced Anti-nutrients: Roasting significantly lowers the levels of anti-nutrients like trypsin inhibitors and phytic acid, which can interfere with mineral absorption.
- Enhanced Flavor and Texture: The process creates a pleasant, nutty flavor and a satisfyingly crunchy texture, making them a more appealing snack.
Roasted Soybeans vs. Other Snacks: A Nutritional Comparison
Choosing snacks wisely is key for managing weight and overall health. Here's how 100g of roasted soybeans stacks up against other common snacks.
| Snack (100g) | Approx. Calories | Protein (g) | Fiber (g) | Key Advantage |
|---|---|---|---|---|
| Roasted Soybeans | 451 | 40 | 8 | High-Protein, High-Fiber, Vegan |
| Almonds (Roasted) | 579 | 21 | 12 | Heart-Healthy Fats, Vitamin E |
| Potato Chips | 536 | 6 | 4 | Convenience, but high in fat and sodium |
| Beef Jerky | 410 | 33 | 0 | Very High Protein, Low Carb |
| Trail Mix (with chocolate) | 500 | 14 | 5 | Energy Boost, Varied Nutrients |
As the table shows, roasted soybeans offer a very high protein and fiber content for their calorie load compared to many other snacks. While almonds are higher in fiber, soybeans provide significantly more protein per 100g. They are also a healthier choice than processed snacks like potato chips, which offer less nutritional value.
