Nutritional Profile of Apples:

Apples are primarily composed of water and carbohydrates, with small amounts of protein and almost no fat. Here’s a breakdown of the key nutrients found in a medium-sized apple (about 182 grams):

  • Calories: Approximately 95 calories
  • Carbohydrates: Around 25 grams, mainly in the form of natural sugars like fructose and glucose, along with dietary fiber.
  • Fiber: Provides about 4 grams of dietary fiber, which aids in digestion, promotes satiety, and helps regulate blood sugar levels.
  • Vitamin C: Contains around 14% of the recommended daily intake of vitamin C, an antioxidant that supports immune function and collagen synthesis.
  • Potassium: Provides about 6% of the recommended daily intake of potassium, an essential mineral that helps regulate blood pressure and fluid balance.
  • Vitamin K: Offers a small amount of vitamin K, which is important for blood clotting and bone health.
  • Other Nutrients: Apples also contain small amounts of vitamin A, vitamin E, vitamin B6, and various minerals like calcium, magnesium, and phosphorus.

Phytochemicals and Antioxidants in Apples:

Apples are rich in phytochemicals, including flavonoids, phenolic acids, and other polyphenols, which contribute to their antioxidant properties. Some of the key antioxidants found in apples include:

  • Quercetin: A flavonoid with anti-inflammatory and antiviral properties, quercetin may help protect against chronic diseases like heart disease and certain types of cancer.
  • Catechins: These flavonoids have been associated with reduced risk of cardiovascular disease and improved cholesterol levels.
  • Chlorogenic Acid: Found predominantly in apple skin, chlorogenic acid has antioxidant and anti-inflammatory effects and may help regulate blood sugar levels.
  • Phloridzin: A unique antioxidant found primarily in apples, phloridzin has been studied for its potential role in bone health and metabolic regulation.

Nutritional Profile of Onions:

Onions are low in calories and carbohydrates but packed with flavor and nutritional goodness. A medium-sized onion (about 110 grams) contains the following nutrients:

  • Calories: Approximately 44 calories
  • Carbohydrates: Provides around 10 grams of carbohydrates, including sugars and dietary fiber.
  • Fiber: Contains approximately 2 grams of dietary fiber, which supports digestive health and promotes feelings of fullness.
  • Vitamin C: Offers about 10% of the recommended daily intake of vitamin C, an important antioxidant that boosts immunity and supports collagen production.
  • Folate: Provides a small amount of folate, a B-vitamin essential for DNA synthesis and cell division.
