Toisin kuin Potilaan Lääkärilehden otsikko väittää, tutkimus ei osoita, että ”kasvisruokavalio ei vaaranna luuston terveyttä”.
Se osoittaa vain, että planeettadieetin mukainen syöminen on mahdollista, kun asiantuntemusta riittää, suunnitella siten, että kuudessa viikossa eivät luuston terveyden biomarkkerit vilkuta punaista.
Punaisen lihan määrä oli tutkimuksessa planeettasuosituksen mukaisessa maksimissaan (kasvisruokavalio?) ja ruuat korostettiin muutenkin viimeisen päälle ammattitaidolla.
Tämä ei vastaa lainkaan sitä tilannetta kun tavallinen pulliainen yrittää noudattaa planeettasuositusta.
Mitä kasvissyöntiin ja luuston terveyteen tulee, Leedsin yliopiston tuoreen tutkimuksen mukaan kasvissyöjillän on huomattavasti suurempi lonkkamurtuman riski kuin säännöllisesti lihaa syövillä.

Abstract
Background
Meat-free diets may be associated with a higher risk of hip fracture, but prospective evidence is limited. We aimed to investigate the risk of hip fracture in occasional meat-eaters, pescatarians, and vegetarians compared to regular meat-eaters in the UK Biobank, and to explore the role of potential mediators of any observed risk differences.
Methods
Middle-aged UK adults were classified as regular meat-eaters (n = 258,765), occasional meat-eaters (n = 137,954), pescatarians (n = 9557), or vegetarians (n = 7638) based on dietary and lifestyle information at recruitment (2006–2010). Incident hip fractures were identified by record linkage to Hospital Episode Statistics up to September 2021. Multivariable Cox regression models were used to estimate associations between each diet group and hip fracture risk, with regular meat-eaters as the reference group, over a median follow-up time of 12.5 years.
Results
Among 413,914 women, 3503 hip fractures were observed. After adjustment for confounders, vegetarians (HR (95% CI): 1.50 (1.18, 1.91)) but not occasional meat-eaters (0.99 (0.93, 1.07)) or pescatarians (1.08 (0.86, 1.35)) had a greater risk of hip fracture than regular meat-eaters. This is equivalent to an adjusted absolute risk difference of 3.2 (1.2, 5.

more hip fractures per 1000 people over 10 years in vegetarians. There was limited evidence of effect modification by BMI on hip fracture risk across diet groups (pinteraction = 0.08), and no clear evidence of effect modification by age or sex (pinteraction = 0.9 and 0.3, respectively). Mediation analyses suggest that BMI explained 28% of the observed risk difference between vegetarians and regular meat-eaters (95% CI: 1.1%, 69.8%).
Discussion
Vegetarian men and women had a higher risk of hip fracture than regular meat-eaters, and this was partly explained by their lower BMI. Ensuring adequate nutrient intake and weight management are therefore particularly important in vegetarians in the context of hip fracture prevention.
