Define about the nutritional deficiencies?

The nutritional deficiencies which have been identified in the group of elderly are of total calories, protein, vitamin A, vitamin C, iron and riboflavin. Folate deficiency in elderly not only produces anaemia but is also associated with dementia. Zinc deficiency has been associated with psychosis (a mental state in which thought and perception are severely impaired) and anorexia. Potassium deficiency could cause confusion and apathy in elderly and irritability could result from magnesium deficiency. Chronic vitamin D deficiency can accelerate bone loss and precipitate osteoporosis, spinal compression fractures, and hip and wrist fractures, especially in elderly women.
