Factors affecting nutritional well-being

An informed food-purchasing decision considers several factors together: freshness, quality, safety, price, nutritional value and the needs of the family. Choosing only the cheapest or most attractive package may lead to poor nutrition or unsafe food. Checking labels and expiry dates also helps consumers make responsible and balanced choices.

Nutritional requirements change with age, growth, pregnancy, lactation, physical activity and health status. Adolescents need nutrients for rapid growth, pregnant women need additional nutrients for maternal and fetal development, and older adults may need adjustments for lower energy needs or health conditions. Therefore, nutrition planning should be based on life stage and individual circumstances.

Pregnancy is a special physiological stage in which the mother must support her own health as well as the growth of the fetus. Energy, protein, iron, folate, iodine, calcium, and other nutrient needs require careful attention, especially when intake is low. Individual assessment and professional guidance are important, so option B is correct.

A baseline survey measures the situation before an intervention begins, such as dietary intake, anaemia, growth, food access or nutrition knowledge. These starting data help planners identify priorities, select suitable activities and set measurable targets. Later measurements can be compared with the baseline to judge whether the programme produced meaningful improvement rather than relying on impressions alone.

Good diet planning must balance nutrient adequacy, affordability, availability, taste, culture, and medical needs. The dietitian can use local, seasonal, minimally processed, and nutrient-dense foods to meet requirements within the person’s resources. Simply choosing the cheapest food or reducing portions may cause deficiency and poor adherence. A realistic plan is one the patient can purchase, prepare, accept, and follow safely.

Environmental barriers are conditions around a person that make healthy eating or adherence difficult. Examples include limited availability of nutritious foods, high prices, unsafe markets, lack of refrigeration, inadequate cooking facilities or transport problems. Recognising these barriers allows the dietitian to suggest realistic alternatives rather than blaming the patient. Therefore, option A is correct.
