Worked Solution & Example Answer:Discuss how the nutrients lacking in a vegan diet could lead to the following: 3.3.1 Osteoporosis 3.3.2 Anaemia - NSC Consumer Studies - Question 3 - 2021 - Paper 1
Step 1
Osteoporosis
Answer
A vegan diet often lacks essential nutrients such as calcium and vitamin D, which are crucial for bone health. Calcium is vital for maintaining bone density, and without it, bones can become brittle and more prone to fractures. Vitamin D helps in the absorption of calcium; thus, a deficiency in either can lead to osteoporosis. Additionally, vegans may not consume fortified foods or supplements that provide these nutrients, exacerbating the risk of osteoporosis.
Step 2
Anaemia
Answer
Anaemia can result from a vegan diet due to a deficiency in iron and vitamin B12. Iron is essential for hemoglobin production in red blood cells, and it is predominantly found in animal products. A lack of this nutrient can lead to insufficient oxygen transport in the body, resulting in fatigue and weakness. Furthermore, vitamin B12, which is not present in plant-based foods, is necessary for red blood cell formation. A deficiency in vitamin B12 can cause megaloblastic anaemia, leading to further health complications.
