A Very Large Banana (Musa sapientum), weighing approximately 152 grams without the peel, presents a substantial contribution to daily energy and nutrient intake, primarily serving as an excellent source of quick, digestible carbohydrates.
From a nutritional standpoint, this single serving delivers around 135 calories, making it an energy-dense option ideal for pre- or post-exercise replenishment. The primary macronutrient is carbohydrates, clocking in at approximately 34.7 grams, of which a significant portion is comprised of natural sugars (fructose, glucose, and sucrose), offering a balanced glycemic response when consumed as part of a varied meal.
Crucially, this very large specimen provides nearly 4 grams of dietary fiber. This soluble and insoluble fiber blend aids significantly in promoting digestive regularity, moderating blood sugar absorption, and supporting long-term satiety. The net carbohydrate count remains manageable at about 30.8 grams.
While low in protein (1.7 grams) and minimal in fat (0.5 grams, mostly unsaturated), the banana's true value lies in its micronutrient profile. It is renowned for its exceptional potassium content, supplying over 540 milligrams in this large size, which is vital for maintaining fluid balance, nerve signaling, and optimal muscle contraction, directly supporting cardiovascular health and blood pressure regulation.
Furthermore, the banana is a powerhouse of Vitamin B6, providing a high percentage of the daily value. Vitamin B6 is essential for numerous metabolic functions, including protein metabolism and red blood cell formation. It also offers a respectable amount of Vitamin C (around 13 mg), which acts as a critical antioxidant, bolstering immune function and aiding in collagen synthesis. Minor but valuable contributions include magnesium, manganese, and trace amounts of folate and zinc, ensuring this ubiquitous fruit is far more than just a sweet treat—it is a cornerstone of a potassium-rich, whole-foods diet. This serving size ensures maximum delivery of essential energy substrates and hydration support due to its high water content.
