Understanding Deficiency Diseases
Deficiency diseases occur when the body lacks essential nutrients over a prolonged period. These nutrients are vital for various bodily functions, and their absence can lead to serious health issues.
Key Reasons for Deficiency Diseases:
- Lack of Nutrients:
Prolonged absence of specific nutrients, such as vitamins and minerals, leads to deficiency diseases. For example, a lack of Vitamin C can result in scurvy, while insufficient Vitamin D can cause rickets.
- Balanced Diet Importance:
A balanced diet provides all the necessary nutrients required for the body's optimal functioning. When the diet is lacking in variety, the risk of developing deficiency diseases increases.
- Long-term Effects:
Deficiency diseases develop gradually. For instance, if someone consistently misses out on essential nutrients over months or years, symptoms may take time to manifest, but they can be severe.
Other Options Explained:
- Overeating (Option A):
Overeating can lead to obesity and other health problems but does not cause deficiency diseases.
- Sudden Lack of Water (Option C):
While dehydration is harmful, it is not classified as a deficiency disease in the same sense as nutrient deficiencies.
- Excessive Exercise (Option D):
While excessive exercise can lead to nutrient depletion, it does not directly cause deficiency diseases unless paired with poor nutrition.
Conclusion:
In summary, deficiency diseases primarily arise from a long-term lack of essential nutrients, making option 'B' the correct answer. Maintaining a balanced diet is crucial for preventing these health issues and ensuring overall well-being.
