Define drawbacks of Nutritional status that assessed traditionally?

Nutritional status assessed traditionally with the use of anthropometric, biochemical clinical and dietary analysis has drawbacks. These include:

• Data for elders is compared with normal values for younger persons.
• Physical condition of elders makes some measurements difficult.
• RDA's for those over 50 years of age not available.
• Nutrient deficiency signs and symptoms are inappropriately attributed to normal aging.

Nutritional screening programmes, therefore, have been designed to assess for presence of malnutrition and some of the causes.
