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- A vegan diet is more effective for weight loss and cholesterol control than a Mediterranean diet, a new study suggests.
The findings, published in the Journal of the American College of Nutrition, indicated that the study participants lost an average of 6 kilograms on the vegan diet, compared with no mean change on the Mediterranean diet.
"Previous studies have suggested that both Mediterranean and vegan diets improve body weight and cardiometabolic risk factors, but until now, their relative efficacy had not been compared in a randomized trial," said researcher Hana Kahleova from the Physicians Committee for Responsible Medicine, a non-profit organization in the US.
According to the researchers, a low-fat vegan diet has better outcomes for weight, body composition, insulin sensitivity, and cholesterol levels, compared with a Mediterranean diet.
For the study, the team randomly assigned participants -- who were overweight and had no history of diabetes -- to a vegan diet or a Mediterranean diet in a 1:1 ratio.
For 16 weeks, half of the participants started with a low-fat vegan diet that eliminated animal products and focused on fruits, vegetables, whole grains, and legumes.
The other half started with the Mediterranean diet, which followed the PREDIMED protocol, which focuses on fruits, vegetables, legumes, fish, low-fat dairy, and extra virgin olive oil, while limiting or avoiding red meat and saturated fats.
The study found that the vegan diet decreased total and LDL cholesterol levels by 18.7 mg/dL and 15.3 mg/dL, respectively, while there were no significant cholesterol changes on the Mediterranean diet.
Blood pressure decreased on both diets, but more on the Mediterranean diet, the researchers said. (agency)
London, If your child is fully vegan, then there are chances that they may have a lower level of vitamin D, a new study suggests.
The findings indicate that children on a fully vegan diet were found to have significantly lower vitamin D levels compared to children without a special diet despite having regular vitamin D supplementation.
Along with that, the study also suggested that their vitamin A status was lowered too.
"Our results indicate that the health effects of strict diets on children cannot be extrapolated from studies on adults. In addition to vitamin D intake, attention must be paid to adequate intake of vitamin A and protein from various sources." said researcher Topi Hovinen from the University of Helsinki.
Vegan diets gain popularity especially among young adults and through choices of the families vegan diet is becoming more common in young children, too.
The motives behind choosing a vegan lifestyle are ecological, ethical and health-related -- vegan diets exclude all animal-based products.
According to the researchers, it is recommended that full vegan diet is always supplemented with vitamin B12, vitamin D and iodine and based on individual assessment the supplementation for calcium, vitamin B2, iron and zinc may be needed.
For the study, published in the journal EMBO Molecular Medicine, the research team studied comprehensively the nutrition and metabolism of 40 healthy children.
The children were following a vegan, vegetarian or omnivore diet according to the choice of their families. Their nutritional intake, metabolic biomarkers and micronutrient statuses were extensively studied.
Levels for LDL and HDL cholesterol, essential amino acid and docosahexaenoic acid, a fatty acid with a central role in development of visual function, were low while folate levels were remarkably high in vegan children, the researchers found.
The team says that the new findings motivate further and larger studies on the health consequences of a vegan diet in young children. (IANS)
London - This is for the one who finds it difficult to stick to a strict vegetarian diet, read on. Researchers have revealed that consuming a plant-based diet can lower blood pressure even if small amounts of meat and dairy are consumed too.
The team argued that any effort to increase plant-based foods in your diet and limit animal products is likely to benefit your blood pressure and reduce your risk of heart attacks, strokes and cardiovascular disease (CVD).
For the study, published in the Journal of Hypertension, the research team conducted a systematic review of previous research from controlled clinical trials.
The team compare seven plant-based diets, several of which included animal products in small amounts, to a standardised control diet and the impact that these had on individuals' blood pressure.
"We reviewed 41 studies involving 8,416 participants, in which the effects of seven different plant-based diets (including DASH, Mediterranean, Vegetarian, Vegan, Nordic, high fibre and high fruit and vegetables) on blood pressure were studied in controlled clinical trials," said study lead author Joshua Gibbs from the University of Warwick in the UK.
Plant-based diets support high consumption of fruits, vegetables, whole grains, legumes, nuts and seeds, limiting the consumption of most or all animal products (mainly meat and dairy).
Vegetarian and vegan diets with a complete absence of animal products are already known to lower blood pressure compared to omnivorous diets. Their feasibility and sustainability are, however, limited.
Until now, it has not been known whether a complete absence of animal products is necessary for plant-based dietary patterns to achieve a significant beneficial effect on blood pressure.
A systematic review and meta-analysis of these studies showed that most of these diets lowered blood pressure.
The findings showed that the DASH diet had the largest effect in reducing blood pressure compared to a control diet.
A blood pressure reduction of the scale caused by higher consumption of plant-based diets, even with limited animal products would result in a 14 per cent reduction in strokes, a nine per cent reduction in heart attacks and a seven per cent reduction in overall mortality.
"This is a significant finding as it highlights that complete eradication of animal products is not necessary to produce reductions and improvements in blood pressure. Essentially, any shift towards a plant-based diet is a good one," Gibbs added,
The study shows the efficacy of a plant-based diet on blood pressure.
"The adoption of plant-based dietary patterns would also play a role in global food sustainability and security," the study authors wrote. (agency)
Vegans follow a plant-based diet and do not eat animal products including dairy, meat, eggs, honey, and gelatin. But, veganism goes beyond the diet.
Veganism is a lifestyle that tries to bar, as far as possible and practicable, all kinds of exploitation of, and cruelty to, animals for food, or any other purpose.
Nutritionist and founder of Diet Podium, Shikha Mahajan, shares these five benefits going vegan has on your health.
1-Reduced risk of cancer
In 2015, the Worle Health Organisation named red meat a Group 2 Carcinogen, which means it probably causes cancer in humans. WHO placed processed meat in the Group 1 category, which means it is carcinogenic to humans.
Even small amounts of meat can increase the risk of cancer. A study from Oxford University study also found that eating just 3 rashers of bacon a day can increase cancer risk by 20 percent.
2-Reduced risk Of diabetes
More and more research is concluding that a plant-based diet can reduce the risk of developing diabetes or even reverse the disease completely.
A study, that included more than 2,000 adults, found those people who increased the number of fruit, vegetables, and nuts in their diet over the duration of 20 years reduced their risk of developing type 2 diabetes by 60 percent more than those who did not.
A study done by the Physicians Committee for Responsible Medicine (PCRM) shows a study on its website that looks at the eating patterns and moods of 3,486 people over a five-year period. The study showed that participants who consumed whole, plant foods reported fewer signs of depression.
A different study showed that vegetarians usually experience more positive moods than meat-eaters.
A plant-based diet might boost your beauty regime by assisting your skin in staying healthy. An increasing number of studies are associating dairy to skin problems such as acne. Dairy products have growth hormones and are also sometimes infused with artificial hormones, which can disrupt the human body's hormone system.
5-Fewer cardiovascular diseases
Meat generally contains a high quantity of saturated and trans-fats which can increase blood cholesterol. Cholesterol can create fatty deposits in the blood vessels that increase the risk of stroke, peripheral artery disease, and heart disease. Plant-based foods, by nature, have no dietary cholesterol. A diet high in fat and cholesterol can also lead to high blood pressure. (Agency)
