| 0:28.5 | We start with the results of a study that has correlated low calcium intake and vitamin D exposure with higher bone fracture rates in British vegans |
| 0:38.2 | Vegetarians that slightly lower bone mineral density in their spines |
| 0:42.2 | Although the difference was basically within the margin of error for the test if the bone quality really is compromised |
| 0:48.3 | they could lead to |
| 0:49.3 | Collapse vertebrae increased spinal fracture risk. There's no evidence for this |
| 0:53.6 | The incidence of vertebral fracture was ascertained in older women who had been vegan for most of their lives |
| 0:59.6 | 34 years on average and despite their calcium intake being terrible about half that of the non-vegans and a quarter of them vitamin D |
| 1:08.7 | Deficient the incidence of vertebral fractures is not significantly different |
| 1:13.4 | Although the vegans had a higher prevalence of vitamin D deficiency and lower dietary calcium intakes the two factors were not |

| 1:32.1 | Vegetarian women had not been found to be at high risk of any kind of fractures including wrist fractures in this case though among |
| 1:38.9 | Vegetarians those who consumed the least vegetable protein intake were at the highest risk for fracture those wait beans every day or nuts or like |
| 1:46.9 | Veggie burgers only had a third of the risk fractures compared to vegetarians who only ate beans or other higher protein foods less than three times a week |
| 1:55.0 | So those are consumer vegan or vegetarian diet may be an increased risk of fracture unless care is taken to ensure an adequate quantity and variety of foods high in protein |
| 2:04.9 | such as whole grains nuts and beans split-piece chickpeas or lentils are in the diet |
