A clinical study conducted by scientists at the German Federal Institute for Risk Assessment (BfR) claimed that following a full vegan diet can lower the value of ultrasound, leading to poor bone health.
A vegan diet is known to have many health benefits ranging from weight loss to cholesterol control, but did you know that following a vegan diet also comes with bad effects?
People on a vegan diet had lower ultrasound readings, indicating poorer bone health, according to a new study. In the German Federal Institute for Risk Assessment (BfR) study, the bone health of 36 vegans, as well as 36 people on a mixed diet, was determined by ultrasound measurement of the heel bone .
Result: On average, people on a vegan diet had lower ultrasound values than the other group. This indicates poorer bone health.
In the study, the scientists also determined biomarkers in the blood and urine. This aims to identify nutrients that may be linked to diet and bone health. Out of 28 parameters of nutritional status and bone metabolism, it was possible to identify twelve biomarkers most strongly associated with bone health – for example, the amino acid lysine and vitamins A and B6.
The results show that in most cases the combination of these biomarkers was present at lower concentrations in vegans. This could be a possible explanation for poor bone health.
“A vegan diet is often considered to be healthy. However, our scientific findings indicate that a vegan diet affects bone health, ”said BfR President Professor Dr Andreas Hensel.
Nutrition plays an important role in bone health. This was studied more closely in the BfR cross-sectional study on the ‘risks and benefits of a vegan diet’. 72 men and women participated in the study.
The bone health of all participants was assessed at the heel bone level using ultrasound measurements. Information on age, smoking, education, body mass index, physical activity and alcohol consumption was also collected.
Using a statistical model, the BfR was able to identify a model of twelve biomarkers that play an important role in bone health from 28 nutritional and bone parameters obtained from blood or urine.
It has been shown that in combination with vitamins A and B6, amino acids lysine and leucine, omega-3 fatty acids, selenoprotein P, iodine, thyroid stimulating hormone, calcium, magnesium and protein a-Klotho were positively associated with bone health. Conversely, lower concentrations of the hormone FGF23 were observed at higher ultrasound levels in this pattern.
Taking into account other scientific studies, the results indicate that vegans consume fewer nutrients relevant to the skeleton and are mainly found in foods of animal origin. —ANI
