Question

Toxic constituents present in pulses include: A. Phytates, B. Saponins, C. Goitrogens, D. Tannins, E. Hemagglutinins.

• A. B, C, D and E only
• B. A, B, C and D only
• C. B, C and D only
• D. A, C and D only

Hint:

Always ensure proper cooking methods are used to reduce the presence of these anti-nutritional factors before consuming pulses.

Answer 1

The Correct Option is A

Step 1: Concept
Pulses are leguminous seeds that include beans, lentils, and peas. They can contain various toxic or anti-nutritional factors which need to be managed through proper cooking methods.

Step 2: Meaning
Phytates, saponins, goitrogens, tannins, and hemagglutinins are examples of such toxic constituents found in pulses. Understanding these components is crucial for ensuring the safety and nutritional value of pulse-based foods.

Step 3: Analysis
Phytates (A): These compounds bind with minerals like iron, zinc, and calcium, making them less available for absorption by the body. Saponins (B): Known to have anti-nutritional effects, they can interfere with nutrient absorption and may cause digestive issues if consumed in large quantities. Goitrogens (C): These substances can inhibit thyroid function by interfering with iodine uptake. They are particularly relevant for individuals with thyroid disorders. Tannins (D): Tannins can bind to proteins, making them less digestible and potentially causing gastrointestinal discomfort. Hemagglutinins (E): These compounds cause red blood cells to clump together, which can lead to digestive issues. The correct answer is provided as A, indicating that all the mentioned toxic constituents are present in pulses. This means that options B, C, and D do not fully encompass the list of toxic constituents found in pulses.

Step 4: Conclusion
Option A (B, C, D, and E only) correctly identifies all the toxic constituents present in pulses. Final Answer: (A)
