London- People consuming vegan diet may have poorer bone health, suggested a new study.
In a new study, the bone health of vegans as well as people following a mixed-food diet was determined with an ultrasound measurement of the heel bone.
The findings showed that people following a vegan diet had lower ultrasound values compared to the other group, which indicates poorer bone health.
"A vegan diet is often considered health-conscious. However, our scientific findings indicate that a vegan diet does affect bone health," researcher Andreas Hensel from the German Federal Institute for Risk Assessment, said in a statement.
For the study, the team investigated a study that involved 72 men and women. The bone health of all participants was assessed at the heel bone using ultrasound measurements.
Information on age, smoking status, education, body mass index, physical activity and alcohol consumption was also collected.
By using a statistical model, the team was able to identify a pattern of twelve biomarkers that play an important role in bone health from 28 nutrition- and bone-relevant parameters from blood or urine.
It was shown that in combination vitamins A and B6, the amino acids lysine and leucine, omega-3 fatty acids, selenoprotein P, iodine, thyroid-stimulating hormone, calcium, magnesium and a-Klotho protein were positively associated with bone health.
Conversely, lower concentrations of the hormone FGF23 were observed at higher ultrasound levels in this pattern. (Agency)
New York, March 3 (IANS) People with kidney stones may be at risk of osteoporosis or bone fracture, says a new study.The study, published in the Journal of Bone and Mineral Research, found that approximately one-quarter of individuals with kidney stones had a diagnosis of osteoporosis or bone fracture around the time of their kidney stone diagnosis."We hope this work raises awareness regarding the possibility of reduced bone strength in patients with kidney stones," said lead author Calyani Ganesan from Stanford University in the US.For the study, the team identified 531,431 patients with kidney stone disease between 2007 and 2015.The team found that 23.6 per cent of patients had a diagnosis of osteoporosis or fracture around the time of their kidney stone diagnosis. In patients with no prior history of osteoporosis or bone analyses before their kidney stone diagnosis, 9.1 per cent received a bone density scan after a kidney stone diagnosis, of whom 20 per cent were subsequently diagnosed with osteoporosis.The findings provide support for wider use of bone density screening in individuals with kidney stones, including middle-aged and older men who may not be recognized as at-risk for osteoporosis or fracture, the researchers said."In our future work, we hope to identify which patients with kidney stones are at higher risk for osteoporosis or fracture to help guide bone density screening efforts by clinicians in this population," Ganesan added.--IANSvc/bg
Lisbon- Although weight loss surgery is a highly effective treatment for obesity, it can be detrimental to bone health, say researchers, adding that exercise may help address this shortcoming.
Exercise has been suggested as a therapeutic approach to attenuate bone loss induced by bariatric surgery (BS), but its effectiveness remains unclear.
The study, published in the Journal of Bone and Mineral Research, aimed to determine if an exercise-training programme could induce benefits on bone mass after bariatric surgery.
"These findings showed that a structured exercise programme may be a valid treatment option to minimize weight loss surgery-induced bone loss, which may be particularly important since many patients undergo surgery in early adulthood or even at pediatric ages," said lead author Florêncio Diniz-Sousa from the University of Porto in Portugal.
The research team randomised 84 patients undergoing weight loss surgery to an exercise group or a control group for 11 months.
The exercise group performed high impact, balance, and resistance exercises three times per week.
Twelve months after surgery, participants in the exercise group had higher bone mineral density measurements at the lumbar spine and the forearm compared with those in the control group.
Also, participants who attended at least half of the exercise sessions had higher bone mineral density at the femoral neck than those in the control group.
The findings suggest that an exercise programme is an effective strategy to ameliorate bone health in post-bariatric surgery patients.
"As stated in recently released World Health Organization physical activity guidelines, regular exercise should be a priority for everyone, including patients who have undergone weight loss surgery," Diniz-Sousa added.(IANS)
London - Compared with people who ate meat, vegans with lower calcium and protein intakes (on average) had a 43 per cent higher risk of fractures anywhere in the body, researchers have warned.
According to the findings, published in the journal BMC Medicine, vegetarians and people who ate fish but not meat had a higher risk of hip fractures, compared to people who ate meat.
However, the risk of fractures was partly reduced once body mass index (BMI), dietary calcium and dietary protein intake were taken into account.
"We found that vegans had a higher risk of total fractures which resulted in close to 20 more cases per 1000 people over a 10-year period compared to people who ate meat," said study author Tammy Tong from the University of Oxford in the UK.
"The biggest differences were for hip fractures, where the risk in vegans was 2.3 times higher than in people who ate meat, equivalent to 15 more cases per 1000 people over 10 years," Tong added.
For the findings, the research team, analysed data from nearly 55,000 people in the EPIC-Oxford study, a prospective cohort of men and women living in the UK, who were recruited between 1993 and 2001, many of whom do not eat meat.
Out of the 54,898 participants included in the present study, 29,380 ate meat, 8,037 ate fish but not meat, 15,499 were vegetarians, and 1,982 were vegans when they were recruited.
Their eating habits were assessed initially at recruitment, then again in 2010. Participants were followed continuously for 18 years on average, until 2016 for the occurrence of fractures.
During the time of the study, 3,941 fractures occurred in total, including 566 arm, 889 wrist, 945 hip, 366 leg, 520 ankle and 467 fractures at other main sites, defined as the clavicle, ribs and vertebrae.
In addition to a higher risk of hip fractures in vegans, vegetarians and pescetarians (those who eat seafood but not meat) than the meat eaters, vegans also had a higher risk of leg fractures and other main site fractures.
The authors observed no significant differences in risks between diet groups for arm, wrist or ankle fractures once BMI was taken into account.
The researchers found that the differences in risk of total and site-specific fractures was partly reduced once BMI, dietary calcium and dietary protein intake had been taken into account.
"This study showed that vegans, who on average had lower BMI as well as lower intakes of calcium and protein than meat eaters, had higher risks of fractures at several sites," the authors wrote. (IANS)
New York - Women who spend a substantial amount of time doing domestic chores such as growing fruits and vegetables, churning butter, beating rugs, washing windows and caring for children have better bone density and overall bone health than women leading sedentary lifestyles, new research has found.
Previous studies in the field have looked at bone density measurements in menopausal women.
This time, the researchers from Beckman Institute for advanced Science and Technology at the University of Illinois at Urbana-Champaign focused on women between the ages of 18 and 46, an age group that is not often looked at in bone density studies.
"We wondered why there was so little research on pre-menopausal women, since presumably their bone density and activity predicts postmenopausal osteoporosis," said Kathryn Clancy, an associate professor of anthropology.
The researchers focused on a population of farmers in rural Poland whose lifestyles involved substantial farm and domestic labour.
They made some basic body measurements and looked at the physical activity patterns of these women.
"We also used a bone sonometer. It is a portable device that can be conveniently used to carry out bone density measurements," Lee informed.
The study found that measures such as grip strength and lean mass are associated with the bone density and frame size of pre-menopausal women.
"We also saw that the bone density of the radius, which is the bone at the base of your thumb, is very high compared to an average white woman of European descent," Lee said in a paper published in the American Journal of Human Biology.
"My work focuses on understanding how our activities shape our skeleton and what it means for the modern population," Lee added.
Moving forward, the researchers said they are interested in understanding whether the childhood environment has helped shape the bone health of the women.(IANS)
Amid the pandemic, work from home, social shielding and discreet outdoor ventures have not only disrupted our emotional well-being but have also drastically affected our physical health. As people are confined to their homes with reduced physical activity there is rapid bone resorption (loss) as muscles and bones are not getting adequate stimulation.
Also lack of exposure to sun during the pandemic has critically affected vitamin D levels in our body. People are frequently feeling tired with lack of energy and strength. Everyone needs to be cautious about the health of their bones as much as their other needs.
Dr Dipesh Mahendra Waghmare, Medical Advisor Executive to Millennium Herbal Care, shares some measures that can take care of your bones during the pandemic.
Eat a well-balanced diet rich in calcium and vitamin D
Good sources of calcium include low-fat dairy products, green leafy veggies and dry fruits. Good sources of vitamin D include fortified cereals, egg yolks, saltwater fish, liver and milk. Calcium and vitamin D work together to protect your bones - calcium helps to build and maintain bones; while vitamin D helps your body to effectively absorb calcium.
Get exposure to sunlight to make enough vitamin D
Regular sun exposure is the most natural way to get enough vitamin D. The sun's ultraviolet B (UVB) rays hit cholesterol in the skin cells, providing the energy for vitamin D synthesis. Vitamin D has a significant role in calcium homeostasis and metabolism. As per pan-India study the best time to get exposed to the sun is between 11am and 1pm since the wavelength of ultraviolet B (UVB) rays is 290-320nm during this period which is essential for skin to make vitamin D.
Live a healthy lifestyle
Smoking and excessive alcohol intake contributes to bone loss and weakened bones. These unhealthy habits unknowingly reduce blood supply to the bones, slow down the production of bone-forming cells and impair the absorption of calcium. By avoiding these habits, you can lower your rate of bone loss and protect your bones from negative impacts.
Get plenty of physical activity Like muscles, bones become stronger with exercise. The best exercises for healthy bones are strength-building and weight-bearing exercise like walking, climbing stairs, lifting weights and dancing. Try to get 30 minutes of exercise each day. Strength-building and weight-bearing exercise provides stimulation to bone cells and helps to increase bone mineral density and bone size thus reducing the risk of osteoporosis.
Ayurveda and phytomedicines for bone health
There are several herbs and phytomedicines mentioned in Ayurveda for promoting bone health. Herbs like Hadjod, Salai guggul, Ashwagandha and Bala are clinically proven to reinstate bone cell homeostasis (osteoblast and osteoclast) and to improve bone mineral density. While herbs like Arjuna, Methi, Lakha serve as an organic source of bio-available calcium, phosphorus, vitamin C, mucopolysaccharrides, minerals and phytoestrogen, of which all are essential components for healthy bones.
The best approach to bone health is adopting proper lifestyle and restoring the healthy balance of bone forming cells (Osteoblast) and bone resorption cells (Osteoclast). As with aging this balance shifts in a negative direction, favoring greater bone loss. Ayurvedic herbs augment bone mass formation and increase its natural healing abilities. Natural or phyto-medicines are free from any kind side effects, can be continued for long term and have sustained benefits for the holistic wellness of your bone health.
