A sample of Toronto family practitioners was surveyed in order to ascertain whether increased dietary calcium was recommended in the treatment of essential hypertension. It was found that in excess of four-fifths of the same make no dietary calcium recommendations. It was concluded that this was the result of one or more of the following: 1. the low priority granted to nutrition in medical schools and continuing education courses contributes to a lack of awareness of nutritional therapies; 2. the relatively small body of literature pertaining to calcium and hypertension in contrast to the large volume of publications concerning drug therapies may contribute to a lack of familiarity with the research into calcium and hypertension; 3. the fact that the data to date have not established a definite causal relationship between low dietary calcium and hypertension may contribute to a lack of conviction as to the efficacy of increased dietary calcium as a treatment.
