Gardening reduces obesity risk
Or is it mainly fitter people who take up gardening? Fat people often have difficulty bending over and getting up. Not too good for weeding
Pottering around in an allotment could cut the risk of obesity, according to a study which found that gardeners weigh about a stone less than their neighbours on average.
As well as providing a form of regular exercise, gardening could encourage people to eat more healthily if they grow their own vegetables, researchers said.
It could also provide an important social benefit for those who share an allotment with others, for example by introducing them to like-minded people with similarly healthy lifestyles.
Researchers from the University of Utah studied a group of 198 gardeners who shared community gardens – an American system similar to allotments – in Salt Lake City.
They compared the gardeners' body mass index (BMI), calculated as someone's weight divided by the square of their height, against their neighbours to determine if their hobby made them healthier.
On average, female community gardeners on average had a BMI which was 1.84 lower than their neighbours, which translates to an 11lb weight loss for a woman measuring 5ft 5in tall.
For male gardeners, BMI scores were 2.36 lower on average – a difference of 16lb in weight for a 5ft 10in man, according to the study published in the American Journal of Public Health.
Female gardeners were also 46 per cent less likely to be overweight or obese than their neighbours. The figure for male gardeners was 62 per cent.
Gardeners were also more likely to have a healthier figure than their siblings, but not their husbands and wives – suggesting that spouses may also benefit from helping out on the allotment and eating the fruits of their labour.
Prof Cathleen Zick, who led the study, said: "This initial study validates the idea that community gardens are a valuable neighbourhood asset that can promote healthier living.
"That could be of interest to urban planners, public health officials and others focused on designing new neighbourhoods and revitalising old ones."
Popular Chinese medicine used for migraines could be FATAL, warn health watchdogs
A herbal medicine used by alternative practitioners to treat migraines could be fatal. Zheng Tian Wan is unregulated but is available in the UK, and it has been linked to serious health complications and death, health authorities say.
The plant remedy contains aconite – a herb once dubbed the ‘Queen of Poisons’ by the ancient Greeks - and could be toxic for the heart and nervous system.
The ingredient is on a UK list of restricted herbal ingredients and the Medicines and Healthcare products Regulatory Agency (MHRA) have issued a statement warning against using the product.
The MHRA said the issue came to their attention after a herbal practitioner supplied a patient the unlicensed migraine pills, which have not been tested for safety and quality.
The agency said it has previously received three reports of suspected side effects to aconite.
One patient suffered kidney problems, a second was hospitalised after suffering dizziness and paraesthesia (pins and needles) and the third experienced palpitations, aches and pains with shortness of breath but recovered after stopping taking the product.
Andrea Farmer, Herbal policy manager at the MHRA, said in certain circumstances herbal medicines could be extremely dangerous: ‘Herbal medicines can have a very significant effect on the body.
'In certain circumstances, such as when aconite is taken orally, they can be extremely dangerous.
'Natural does not mean safe. To help you choose a herbal medicine that is suitable for you, look for a product that has a Traditional Herbal Registration or product license number on the packaging. These products have met the acceptable quality and safety standards.
'And if you think you have suffered a side effect to an herbal medicine, please tell us about it through our Yellow Card Scheme.'
Websites selling Zheng Tian Wan advertise it as a ‘formula with a thousand year history that stops headache and migraine’.
However, MHRA guidelines dictate that aconite should not be used in unlicensed products for oral use and herbal practitioners in the UK are only allowed use aconite externally on unbroken skin.
Products intended for oral use containing aconite are not permitted in the UK without authorisation, while only qualified doctors can prescribe aconite's use in oral medicines, under the prescription-only medicine scheme.
An MHRA spokesman said: 'It's difficult to say how much is out there, because it's a traditional Chinese medicine, so it's not something we regulate.
‘It is also difficult to tell what the levels are in a product without testing it but the fact is, aconite is a particularly toxic product so regardless of the levels we would advice people not to take it.
‘If it was sold online we could have it taken down to have it removed from sale but we do not know where every traditional Chinese practitioner is working.’
They urge anyone who has taken Zheng Tian Wan, which is made by the Shenzhen 999 Chinese Medicine Investment Development Co, or any other aconite-containing product, to speak to their GP or healthcare professionals as soon as possible.
