Vitamin C

Definition

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that plays a crucial role in various bodily functions, including the synthesis of collagen, absorption of iron, and functioning of the immune system. It is an essential nutrient that must be obtained from dietary sources, such as fruits and vegetables, and is particularly important during periods of growth and development, making it significant for both school-age children and individuals planning for pregnancy.

5 Must Know Facts For Your Next Test

1. School-age children require about 25-45 mg of vitamin C daily for proper growth and development.
2. Pregnant women are advised to consume higher amounts of vitamin C, around 85 mg per day, to support fetal development and enhance iron absorption.
3. Vitamin C is abundant in citrus fruits like oranges and lemons, as well as in vegetables like bell peppers and broccoli.
4. Deficiency in vitamin C can lead to scurvy, which is more common in populations with limited access to fresh produce.
5. Vitamin C plays a key role in strengthening the immune system, which is crucial for school-age children who are more susceptible to infections.

Review Questions

• How does vitamin C support the growth and development of school-age children?
  • Vitamin C supports the growth and development of school-age children by aiding in collagen synthesis, which is vital for healthy skin, bones, and connective tissues. Additionally, it enhances the absorption of iron from plant-based foods, helping to prevent anemia. A sufficient intake of vitamin C also boosts their immune system, reducing the risk of infections during this critical period of growth.
• What are the potential health consequences of vitamin C deficiency during pregnancy?
  • Vitamin C deficiency during pregnancy can lead to several health consequences for both the mother and the developing fetus. Insufficient vitamin C may impair collagen formation, leading to complications such as weakened connective tissue or potential birth defects. Additionally, inadequate levels can hinder iron absorption, increasing the risk of anemia in pregnant women and potentially affecting fetal growth and development.
• Evaluate the role of vitamin C as an antioxidant in preventing chronic diseases among adolescents.
  • Vitamin C acts as a powerful antioxidant that protects cells from oxidative stress caused by free radicals. In adolescents, a diet rich in vitamin C can help reduce inflammation and lower the risk of developing chronic diseases such as cardiovascular disease and diabetes later in life. This protective effect emphasizes the importance of maintaining adequate vitamin C levels through fruits and vegetables during this critical period of physical and hormonal changes.
