• Lack of vitamin C causes Scurvy.
• While many animals produce their own vitamin C, humans and a few others do not.
  • The technical way of saying this is “humans are unable to metabolically synthesize vitamin C.”
  • guinea pigs, monkeys - examples of mammals that cannot produce Vitamin C on their own.
• Sources of vitamin C in the food
  • fruits: citrus fruits, amla, guava, kiwifruit, lemons, limes, oranges, papaya, strawberries
  • vegetables: red peppers, bell peppers, chili peppers, broccoli, tomatoes, parsley, brussel sprouts, cabbage, potatoes, spinach, watercress
• Cooking often decreases vitamin C in foods.
• Pasteurized milk does not have vitamin C

  • Pasteurization is a heating process.
    • It makes milk safer for infants to drink.

    • So to get vitamin C, supplement the infant's diet with onion juice or cooked potato.
