Low bone mineral density and bone mineral content are associated with low cobalamin status in adolescents.

Background: Cobalamin deficiency is prevalent in vegetarians and has been associated with increased risk of osteoporosis.

Aim Of The Study: To examine the association between cobalamin status and bone mineral density in adolescents formerly fed a macrobiotic diet and in their counterparts.

Methods: In this cross-sectional study bone mineral density (BMD) and bone mineral content (BMC) were determined by DEXA in 73 adolescents (9-15 y) who were fed a macrobiotic diet up to the age of 6 years followed by a lacto-(-ovo-) vegetarian or omnivorous diet.

Intolerance to dietary biogenic amines: a review.

Objective: To evaluate the scientific evidence for purported intolerance to dietary biogenic amines.

Data Sources: MEDLINE was searched for articles in the English language published between January 1966 and August 2001. The keyword biogenic amin* was combined with hypersens*, allerg*, intoler*, and adverse.

Vitamin B-12 status is associated with bone mineral content and bone mineral density in frail elderly women but not in men.

Subclinical vitamin B-12 deficiency is common in the elderly. Encouraged by early indications, we investigated the plasma vitamin B-12 status in association with bone mineral content (BMC) and bone mineral density (BMD) in frail elderly people. Data of 194 free-living Dutch frail elderly (143 women and 51 men) were available.

Influence of processing on total, monoglutamate and polyglutamate folate contents of leeks, cauliflower, and green beans.

Bioavailability of dietary folate might be impaired by the polyglutamate chain to which approximately 70% of dietary folates are bound. This chain must be removed enzymatically in the intestine before folate is absorbed as a monoglutamate. To increase formation of monoglutamate folate in vegetables, the vegetables were subjected to various processing treatments.
