Description For the third time, specialists from all over the world met to present their most recent scientific results and to update their knowledge in the expand- ing field of nutrition and, osteoporosis. Major nutrition-al factors, such as calcium and vitamin D, were reexamined, with special attention on the ef- fects of calcium, given either as a supplement or in dairy products in chil- dren and adolescents, and to vitamin D supplementation in the elderly.
The RDA for calcium was questioned, and the calcium requirement was rede- fined. Special attention was paid to proteins and their growth promoting action via IGF-l, as well as to the profound effects on calcium and bone metabolism of vegetarian diets or diets rich in acidic or alkaline foods. Although considered an environmental factor influencing the pathogenesis of osteoporosis, nutrition was discussed in relation to genetic conditions, because certain genetic conditions modifY patients' responses to nutritional deficiencies and to supplementary interventions.
These proceedings report the wide spectrum of research currently being undertaken and the new perspectives this presents and emphasize the sig- nificant and important impact of nutrition on bone health and disease.

These earlier studies found BMD to be higher in the vegetarian group compared to those individuals consuming an omnivorous dietary lifestyle [21—27].
However, it is important to note that in the paper by Ellis et al. Additionally, subjects studied in several of the published data were Seventh Day Adventists SDA who had a significantly different lifestyle to that of the omnivorous group. For example, the SDA group refrained from smoking and caffeine intake and their physical levels were higher.
This is likely to have been an important confounding influence, which may have, at least in part, biased some of the study findings. Later studies post in vegetarian populations Cross-sectional and longitudinal population-based studies published in the last two decades suggest no differences in BMD between vegetarians and omnivores [28—32].
Lloyd et al.
Whilst the vegetarian group were found to consume greater quantities of carbohydrate, fibre, magnesium, ascorbic acid, copper and energy as percent carbohydrate, and lower amounts of protein, niacin, alcohol, vitamin B12, cholesterol and energy as percent protein, neither cortical or trabecular bone mass was affected by a lacto-ovo-vegetarian diet. In a 5-year prospective study of changes in radial bone density of elderly white American women mean age of 81 years living in residential communities, no differences were seen in bone loss rates between the lacto-ovo-vegetarians and the omnivorous group .
In the most recently published studies, bone mass was found to be significantly lower in the vegetable-based dietary groups. These types of products are likely to be found in abundance in a lacto-ovo-vegetarian diet. Few studies have reported either a comparison of fruit and vegetable intakes between the groups or the level of intake of dietary alkali. In the study by Marsh et al. Whilst the method used to determine the dietary acid and base excesses i.
Animal vs. It is important to note, however, that in these correlational studies, the unit of measurement is country and not individual and as such, these types of studies have a number of limitations which must be considered in the interpretation of such data. The effect of a high dietary ratio of animal protein to vegetable protein on bone loss and risk of fracture has been investigated in a prospective cohort of women who participated in the Study of Osteoporotic Fractures SOF . Women with a higher ratio of animal to vegetable protein intake had a higher rate of bone loss at the femoral neck than did those with a low ratio as well as a greater risk of hip fracture.
Other published studies that present data specifically examining animal vs. Munger et al. Both population groups had adequate calcium intakes. Of interest to the protein controversy is the growing recognition that dietary calcium may play a crucial role; that is, dietary protein is not detrimental to bone health provided that dietary calcium is in adequate supply .
Whilst there are a number of studies which provide direct support for this [42,43], there remains plausible mechanisms by which alkali salts also have a critical role to play [44—46]. Fruit and vegetable link to bone: other potential mechanisms of action? There are growing data, both observational and experimental which show a positive link between fruit and vegetable consumption and bone health [47,48].
However, more intervention studies are required before a causal link can be claimed. Furthermore, it remains to be determined the exact mechanisms behind a fruit and vegetable link to the skeleton since these foods provide not only a source of dietary alkali but also a wide variety of micronutrients, many of which have plausible workings for an effect on bone. The exciting work by Muhlbauer et al. Discussion There is a clear and urgent need for public health strategies to target prevention of poor bone health on a population-wide basis and, similarly, it is critical that particular dietary habits resulting in the exclusion of specific foods are carefully monitored to ensure that population groups are not placing themselves at an increased risk of osteoporosis or its associated risk factors.
Existing and available data indicate that consumption of a lacto-ovo-vegetarian does not have an over-riding negative or positive effect on skeletal integrity. There is growing support from a combination of clinical, observational and intervention studies for a beneficial effect of fruit and vegetable intake on bone health. Gregory, et al. White, E.
