Chapter 7: Night Blindness

• Night blindness is caused by a lack of vitamin A

• A lack of vitamin A can lead to a dry and cloudy cornea

• Carrots are a source of pro-vitamin A, which stimulates the body to produce more vitamin A

  • Carrots contain beta-carotene, which gives them their orange color

  • Other yellow-orange foods high in beta-carotene can also help prevent night blindness

• Eating foods that contain actual vitamin A is better for the eyes

  • Liver meat, egg yolks, certain dairy products, and fish are good sources of vitamin A

• During World War II, rationing led to nutritional deficiencies that had to be compensated for

  • Carrots were a fallback option for getting vitamin A

• Eating fish, eggs, butter, or liver is more effective for improving night vision than carrots

Conclusion

• Carrots are not the best source of vitamin A for improving night vision

• Eating foods that contain actual vitamin A is more beneficial
