FAQs on Nutrients: Iron & Manganese Video Lecture - Biology for Grade 11
| 1. What are the main sources of iron and manganese in our diet? |  |
Ans. Iron can be found in both animal sources such as red meat, poultry, and seafood, as well as plant-based sources like beans, lentils, and leafy green vegetables. Manganese can be obtained from whole grains, nuts, seeds, and leafy green vegetables.
| 2. How much iron and manganese do we need daily? | |
Ans. The recommended daily intake of iron for adults is 8-18 mg, depending on age and gender. For manganese, the recommended daily intake is 1.8-2.3 mg for adults.
| 3. What are the health benefits of iron and manganese? | |
Ans. Iron is essential for the production of red blood cells, which carry oxygen throughout the body. It also plays a role in energy production and supports a healthy immune system. Manganese is involved in the metabolism of carbohydrates, cholesterol, and amino acids, and is important for bone health and antioxidant function.
| 4. What happens if we have a deficiency of iron or manganese? | |
Ans. Iron deficiency can lead to anemia, characterized by fatigue, weakness, and shortness of breath. Manganese deficiency is rare but can result in poor bone health, impaired glucose tolerance, and altered lipid metabolism.
| 5. Can iron and manganese be toxic if consumed in excess? | |
Ans. Yes, consuming excessive amounts of iron can lead to iron overload, which can cause organ damage and increase the risk of chronic diseases. Similarly, excessive intake of manganese, particularly from supplements or industrial exposure, can lead to neurological symptoms known as manganism. However, it is rare to experience toxicity from dietary sources alone.
