Tempeh's nutrition can vary a bit from brand to brand, but a typical 75 gram serving will contain around 170 calories, 7 grams of fat (1 gram saturated), 10 grams of carbohydrates (about 4 grams coming from fiber and 2 grams from sugar), and a whopping 17 grams of protein. Additionally, you'll get about 6% of your daily calcium and iron, and 8% of your daily potassium. As tempeh is plant-based, it's cholesterol free.
