Correct answer: A. Food habits that affect iron absorption

Option A is correct because the amount of iron absorbed depends not only on the iron content of food but also on the meal pattern. Vitamin C can enhance absorption of non-haem iron, whereas tea or coffee taken close to meals and some inhibitors may reduce it. Advice should also consider the cause of anaemia and any prescribed supplement.

Correct answer: A. To control energy intake

Portion control helps a person manage the amount of energy consumed without requiring the elimination of all food groups. Appropriate portions can reduce excess calorie intake while preserving protein, fibre, vitamins, minerals, and satisfaction. Successful obesity management also includes food quality, regular physical activity, behaviour change, and an achievable long-term plan.

Correct answer: D. The plan may become impractical and reduce adherence

A diet plan must consider household income, food prices, local availability, cooking facilities, and family responsibilities. If recommended foods are unaffordable or difficult to obtain, the person may not follow the plan consistently. Therefore, an effective plan should be nutritious, affordable, available, culturally acceptable, and realistic.
