						a In populations with high fracture incidence only. Applies to men and
						women older than 50-60 years, with a low calcium intake and/or poor vitamin D
						status.b At levels used to fluoridate water supplies. High fluoride intake causes
						fluorosis and may also alter bone matrix. 
						b At levels used to fluoridate water supplies. High fluoride intake
						causes fluorosis and may also alter bone matrix.  
						c Several components of fruits and vegetables are associated with a
						decreased risk at levels of intake within the normal range of consumption (e.g.
						alkalinity, vitamin K, phytoestrogens, potassium, magnesium, boron). Vitamin C
						deficiency (scurvy) results in osteopenic bone disease.
