Step 1
functions in the body
Answer
Iron plays a crucial role in the body, primarily in the formation of hemoglobin, which is essential for transporting oxygen in the blood. Lack of sufficient iron can lead to reduced oxygen delivery to muscles, affecting physical performance. Additionally, iron is involved in myoglobin production, which carries oxygen in muscles. It also assists various enzymes in their function, contributing to energy metabolism and the synthesis of certain hormones. Moreover, iron is vital for preventing anemia, a condition characterized by a lack of healthy red blood cells.
Step 2
dietary sources
Answer
Dietary sources of iron include a variety of foods. Rich sources are red meat, liver, and poultry. Other sources include fish, wholegrain foods, eggs, and a variety of plant-based options such as cereals, legumes, broccolis, cabbages, and pulses. Incorporating these foods into the diet can help ensure adequate iron intake, especially for individuals at higher risk of deficiency.
Step 3
effect of deficiency
Answer
Iron deficiency can lead to several health issues, the most common being tiredness and fatigue due to decreased oxygen supply to tissues. It can also manifest as pale skin, breathlessness, and weakness. In more severe cases, individuals may experience symptoms like brittle nails, headaches, and an increased risk of infections. Long-term deficiency can lead to iron-deficiency anemia, which requires medical attention and dietary adjustments.
