- How hot chilli could help you live longer Monday January 16th, 2017
Vermont University studied 16,000 people and tracked them for 23 years
Study found consumption of hot red chillies associated with reduced mortality
Most common diseases spicy food warded off were heart conditions and stroke
If you like curry then there is now even more reason to tuck in – it could help you live longer.
People who ate hot chilli peppers were 13 per cent less likely to die than those who did not.

A study said that diners get the benefit so long as they are eating hot peppers, meaning that anything from curry to Mexican food could give you the benefit.
Spicy food has long been thought to be beneficial in the treatment of diseases but only one previous study looked at its relationship with mortality.
The researchers from Vermont University in the US looked at study which examined the eating habits of 16,000 Americans who were tracked for 23 years.
Over that time 4,946 people died.
Total mortality for participants who consumed hot red chilli peppers was 21.6 per cent compared to 33.6 per cent for those who did not, a difference of 12 per cent.
Adjusted for demographic, lifestyle, and clinical characteristics, the difference was 13 per cent.
Medical student Mustafa Chopan and Professor of Medicine Benjamin Littenberg found that the lifestyle of the typical person who ate chilli peppers did not give any particular sign as to why they lived longer.
The analysis found they were more likely to be younger, male and married.
They were also more likely to drink alcohol, eat more vegetables and meats, had lower cholesterol, lower income and be less educated
How chemical compound capsaicin makes chilli so fiery

Instead the findings suggested that something on the outer surface of cells in the human body called Transient Receptor Potential (TRP) channels, could be responsible.
They are the primary receptors for pungent agents such as capsaicin, the principal component in chili peppers.
The study said: ‘In this large population-based prospective study, the consumption of hot red chili pepper was associated with reduced mortality. Hot red chili peppers may be a beneficial component of the diet’.
The previous study which looked into hot peppers and mortality was published in China in 2015.

- Don’t want to get dementia? Then have a chicory salad for lunch Saturday January 14th, 2017
A component of chicory helps to reduce memory loss, a new study has found
This is a sign of dementia – believed to be caused by toxic clumps in the brain
But chicoric acid – also found in lettuce – may help to prevent their formation
Having a chicory salad for lunch could stop you from getting dementia, scientists claim.
A component of the vegetable helps to reduce memory loss – one of the earliest signs of the disease, a new study has found.
Chicoric acid may help prevent the formation of toxic clumps, known as amyloid plaques, in the brain.
These are believed to be the signature hallmark of the disease, affecting the organ’s ability to work effectively.
And experts believe the substance, which also resides in lettuce and dandelion, could be used in future to prevent the build-up of clumps.
A component of chicory helps to reduce memory loss – one of the earliest signs of the disease
Chinese researchers discovered it worked by blocking a major brain pathway known to cause the amyloid plaques.
These form when proteins fold abnormally in the brain, having toxic effects on the organ and causing memory loss.
To test the effects of chicoric acid on memory, Chinese researchers used three groups of mice.
Some rodents were given lipopolysaccharide (LPS), while others received both this and chicoric acid. A control group was also assessed.
Their learning and memory capabilities were evaluated four hours after being injected through two separate tests.
They found the LPS-only group took a longer time to find a specified platform compared to the control group.
Chicoric acid was discovered to help prevent the formation of toxic clumps in the brain – the signature hallmark of dementia
But the rodents who received the chicoric acid supplements were much quicker at performing the task, the study published in The FASEB Journal found.
The Northwest A&F University, in Yangling, researchers then removed the platform and instead marked a target area to assess how they responded.
Those treated with chicoric acid displayed a significant increase in the average time spent in the designated area.
While those who only received LPS spent less time there – even compared to the control group.
This comes just days after a Canadian study found couch potatoes are just as likely to get dementia as those born with a specific gene.
Their findings mean that even without genetic risk factors, over-65s who rarely exercise are among the most likely to develop the disease.

- Urine test reveals what you really eat Saturday January 14th, 2017
A urine test that can reveal how healthy your meals are has been developed by UK scientists.
They think it could be used to improve nutritional advice or in weight loss because people are notoriously bad at recording their own eating habits.
The test, detailed in the Lancet Diabetes and Endocrinology, detects chemicals made as food is processed by the body.
The research team believe it could be widely available within two years.
The urine samples are analysed to determine the structure of the chemicals floating around in it using a technique called a proton nuclear magnetic resonance spectroscopy.
This gives clues to both recent meals and long term dietary habits.
The results of your body processing fruit, vegetables, fish and different types of meat leave a distinct signature in the urine.
Clues to the state of the body’s metabolism and gut health can also be detected by investigating the chemicals in it.
The test was developed by a collaboration between Imperial College London, Newcastle University and Aberystwyth University.
Dr Isabel Garcia-Perez, one of the researchers at Imperial, said: “This will eventually provide a tool for personalised dietary monitoring to help maintain a healthy lifestyle.
“We’re not at the stage yet where the test can tell us a person ate 15 chips yesterday and two sausages, but it’s on the way.”
Could urine be more accurate than food diaries?
In trials, around 60% of people either under or over report what they are eating.
Prof Gary Frost, another scientist at Imperial, said this could be the first independent test of what people munch on at home.
He told the BBC News website: “You can really tell whether someone’s been following a healthy diet or not.
“The bigger you are the more likely you are to under-report what you eat.
“People find it difficult to open up to what types of foods they eat at home, which is a major problem.”
The researchers believe the test results could help combat people’s obesity or risk of diseases such as type 2 diabetes.
Prof Frost said: “If someone is very big and their profile says they’re eating lots of energy dense foods like meat, then you can try to change that profile and then test them again later.
“It remains to be seen, but people might respond better to that and there is a desperate need for tools to help people change their diet.”
He says doing the test on large numbers of people would build up a picture of what the nation was really eating, which could be used to design better public health campaigns.
The scientists were able to spot the difference between healthy and unhealthy diets after tests on 19 people who spent days eating a carefully controlled set of meals.
Four diets of varying degrees of healthiness were given to the patients and their urine was sampled morning, noon and night.
Dr Des Walsh, from the UK Medical Research Council, commented: “Though this research is still in its early stages, it’s grappling with essential methods in food and diet studies where advances are really needed.
“Measuring what we eat and drink more accurately will widen the benefits of nutrition research, developing better evidence-based interventions to improve an individual’s health and reduce obesity.”
