Aalu Ki Sabji, a quintessential North Indian staple, is essentially a preparation of potatoes (Aalu) cooked with various aromatic spices and typically a small amount of oil or ghee. Nutritionally, this dish is defined by its primary ingredient, the potato (Solanum tuberosum), making it a significant source of complex carbohydrates, which serve as the body's preferred source of energy.

Per 100 grams, Aalu Ki Sabji provides approximately 110 calories, predominantly derived from starches. The carbohydrate content is substantial, offering readily available glucose for cellular function and physical activity. Importantly, potatoes contribute dietary fiber, aiding in digestive regularity and promoting satiety, though the fiber content is higher if the potato skins are retained.

From a micronutrient standpoint, the dish excels in potassium, an essential electrolyte vital for maintaining fluid balance, nerve signaling, and optimal muscle contraction, including cardiac function. It also contains modest amounts of Vitamin C, a powerful antioxidant (though cooking reduces the native vitamin C levels), and B vitamins like Niacin and B6. The fat content (around 4 grams per 100g) is crucial to consider, as this is highly variable based on the cooking method—deep-fried preparations (like puri-sabji) will dramatically increase caloric and saturated fat density, whereas light tempering (tarka) results in a healthier profile. The protein content is relatively low but offers a spectrum of amino acids. As a nutritionist, I emphasize mindful consumption, pairing this energy-dense preparation with complementary sources of lean protein and non-starchy vegetables to create a balanced meal structure.

The inclusion of spices (turmeric, cumin, coriander) also introduces beneficial phytonutrients, though their concentration is minor, enhancing overall palatability and antioxidant potential.
