A 50-gram portion, typically representing one-third of a standard medium avocado, is a powerhouse of healthy monounsaturated fats, primarily oleic acid. From a nutritional perspective, this serving size provides approximately 80 calories, predominantly derived from its lipid profile. This lipid composition is crucial for cardiovascular health, aiding in the maintenance of healthy cholesterol levels by potentially lowering LDL ("bad") cholesterol while preserving HDL ("good") cholesterol.

Carbohydrates are notably low in avocado, with only about 4.3 grams per serving. Crucially, over 3.3 grams of this is dietary fiber. This high fiber content means the net carbohydrate count remains exceptionally low (around 1 gram), making it an excellent food choice for managing blood sugar and supporting ketogenic or low-carb dietary regimens. The fiber also contributes significantly to gut health and promotes satiety, which is beneficial for weight management.

The protein content is modest, around 1.0 gram, providing a small contribution to daily amino acid intake.

Beyond macronutrients, a third of an avocado is rich in essential micronutrients. It provides a significant dose of Vitamin K (around 10.5 mcg), vital for blood clotting and bone health, and Folate (about 40.5 mcg DFE), necessary for cell division and repair. Potassium levels are also impressive (approximately 242.5 mg), playing a critical role in fluid balance and blood pressure regulation. Furthermore, this portion delivers measurable amounts of Vitamin E, a potent antioxidant, and Vitamin C. Its nutrient density, combined with its high content of beneficial fats, solidifies the avocado's reputation as a highly valuable component of a balanced, health-conscious diet.
