“…A low intake of iron may also decrease the absorption of folic acid and vitamin B 12 , thus further contributing to nutritional anemias among the elderly (2). Circulating vitamin C (16, 18), B 6 (16), thiamine (18, 19), vitamin B 12 (16), folic acid (3), and pantothenate (20) decline with aging though the causes for these declines are obscure. Most of the deficiencies detected in the elderly are subclinical (4, 16).…”

Absorption of folates, vitamin B6, pantothenate, and riboflavin from a natural food source (yeast) and from synthetic folylmonoglutamate was studied in 24 elderly subjects (age range, 73 to 101 years) and in 12 healthy younger subjects (age range, 24 to 42 years). All subjects absorbed riboflavin, vitamin B6, and pantothenate from yeast. Ingested folypolyglutamates (the preponderant folates in yeast) proved to be a very poor source of folates for the elderly subjects, whereas synthetic folylmonoglutamate served as a good source. In the younger subjects, yeast was a significant folate source. It is suggested that the folate deficits so common in the elderly are caused by impaired ability to obtain folate from ingested foods. The resultant folate deficit may induce changes in the epithelial structure and enzyme secretion of the small bowel, which may further exacerbate folate malabsorption.

“…Folate deficiency is common in the elderly (1, 18). In one study of 93 such patients, 40 percent showed blood levels low in folate, with consequent anemia; in 30 percent of this group, dietary folate deficiency clearly accounted for the anemia (1).…”

“…As th'e active cell mass decreases, it is reflected by a fall in resting metabolic rate. There is a decrease in basal metabolic rate of about 20% between the ages of 25 and 65 (Bender, 1971). 3, decline in physical activity.…”
