Apples are considered nutrient-dense fruits, meaning they provide a lot of nutrients per serving.
The current Dietary Guidelines for Americans recommend 2 cups of fruit daily for a 2,000-calorie diet, emphasizing whole fruits, like apples (2Trusted Source).
One medium 7-ounce (200-grams) apple offers the following nutrients (3Trusted Source):
Calories: 104
Carbs: 28 grams
Fiber: 5 grams
Vitamin C: 10% of the Daily Value (DV)
Copper: 6% of the DV
Potassium: 5% of the DV
Vitamin K: 4% of the DV
The same serving also provides 2–5% of the DV for vitamins E, B1, and B6.
Vitamin E serves as a fat-soluble antioxidant, vitamin B1 — also known as thiamine — is needed for growth and development, and vitamin B6 is essential for protein metabolism (4Trusted Source, 5Trusted Source, 6Trusted Source).
Apples are also a rich source of polyphenols, an important group of antioxidants. Antioxidants are compounds that protect your cells from free radicals — harmful molecules that contribute to the development of chronic conditions, like heart disease and cancer (4Trusted Source).
While nutrition labels don’t list these plant compounds, they’re likely responsible for many of apples’ health benefits (1Trusted Source)
To get the most out of apples, leave the skin on, as it contains half of the fiber and most of the polyphenols (7Trusted Source, 8Trusted Source).
