A slice of apple, intrinsically representing the nutritional profile of the whole fruit, offers a delightful combination of low caloric density and beneficial micronutrients. Based on a standard 100-gram serving (equivalent to roughly 3-5 typical slices, or about half a medium apple), this fruit is remarkably low in total fat, containing virtually zero grams (approximately 0.17g), and negligible levels of saturated and trans fats, positioning it as a heart-healthy choice.

The primary macro-nutrient component is carbohydrates, providing around 13.8 grams per 100g. Crucially, a significant portion of this carbohydrate content comes from dietary fiber (around 2.4 grams), primarily insoluble fiber found in the skin. This fiber content is vital for promoting digestive health, aiding in bowel regularity, and contributing to satiety, which is beneficial for weight management strategies. The fiber also helps modulate blood glucose response, making the glycemic impact generally moderate. The resulting net carb count is approximately 11.41 grams, making it suitable for balanced dietary approaches.

While apples contain natural sugars—approximately 10.4 grams, mainly fructose, glucose, and sucrose—the concurrent presence of fiber mitigates rapid absorption. Apples are also a source of important vitamins and minerals, albeit not overwhelmingly rich in any single one. They offer modest amounts of Vitamin C (4.6 mg), an essential antioxidant vital for immune function and collagen synthesis, and Vitamin K (2.2 µg), important for blood clotting and bone health. Potassium (107 mg) is also present, contributing to fluid balance and nerve signaling.

Furthermore, the phytonutrient profile, concentrated largely in the skin, includes potent antioxidants like quercetin, catechin, and phloridzin. These compounds are studied for their potential roles in reducing oxidative stress and chronic disease risk. The overall hydration level is exceptionally high, with water making up over 85% of the apple’s mass, contributing significantly to fluid balance. Incorporating apple slices into your diet is an excellent way to boost antioxidant intake, support gut health, and enjoy a naturally sweet, nutrient-dense snack.
