Question

who may need a nutrient supplement and why? list examples of valid reasons for taking supplements.

Explanation:

1. Pregnant Women: Need folic acid supplements to prevent neural tube defects in the fetus. Folic acid is crucial for fetal development, and dietary intake alone may not be sufficient.
2. Vegans/Vegetarians: May need vitamin B12 supplements. Vitamin B12 is primarily found in animal products, so those avoiding animal foods can develop deficiencies, leading to neurological issues and anemia.
3. Elderly People: Often require vitamin D and calcium supplements. Aging reduces the skin's ability to synthesize vitamin D from sunlight, and calcium absorption decreases, increasing the risk of osteoporosis.
4. Athletes/High - Intensity Exercisers: Might need protein or creatine supplements. Intense physical activity increases nutrient demands; protein helps in muscle repair and growth, while creatine can enhance performance in short - duration, high - intensity exercises.
5. People with Malabsorption Disorders (e.g., Celiac Disease): May need various vitamin and mineral supplements (like iron, vitamin D). The disorder impairs the absorption of nutrients from food, so supplements can help meet nutritional needs.

Answer:

• Pregnant Women: Need folic acid supplements to prevent neural tube defects in the fetus.
• Vegans/Vegetarians: May need vitamin B12 supplements due to lack of animal - based food sources.
• Elderly People: Often require vitamin D and calcium supplements due to reduced synthesis/absorption.
• Athletes/High - Intensity Exercisers: Might need protein or creatine supplements to meet increased nutrient demands.
• People with Malabsorption Disorders: May need vitamin and mineral supplements to compensate for impaired nutrient absorption.
