How fear can be ‘programmed’ into infants

If the thought of the dentist’s drill sets your teeth on edge, blame your mother.
Babies may develop a deep-seated of the dentist before they even grow their first teeth, scientists say. They believe that fear can be passed between generations, with mother to child the primary route.
The tantalising idea comes from research into the ‘smell of fear’. The US study showed that newborn rats learn what to fear by sniffing odours given off by their mothers.
The researchers believe something similar happens in people, with babies picking up on changes to their mother’s voice, face, movements or even their smell.

Eating just two servings of nuts a day may combat type 2 diabetes

Eating nuts may help to combat type 2 diabetes, new research suggest. 
Two servings of tree nuts a day appears to lower and stabilise blood sugar levels in people with the disease, according to evidence collected from 12 clinical trials. Tree nuts cover most types including walnuts, cashews, hazelnuts and pecans, but exclude peanuts.  A single serving was defined as 30 grams. 
Nut consumption improved two key markers of blood sugar, the results from analysing data on 450 trial participants showed. One, the HbA1c test, measures blood sugar levels over three months. The other, the fasting glucose test, assesses blood sugar after the patient has not eaten for eight hours.

Eating more than five a day has ‘no extra health benefit,’ claim researchers

Eating more portions of fruit and vegetables than the recommended “five a day” has no additional benefit on reducing a person’s risk of death, researchers have suggested.
The findings contradict recent research which found that eating “seven a day” holds the lowest risk of death. The latest study, published on thebmj.com, examined the association between fruit and vegetable intake and risk of premature death.
Consuming five portions of fruit or vegetables is linked to a lower risk of premature death, but eating more portions appears to have no further effect, the study concluded.

Too much protein in middle age 'as bad as smoking'

Two new studies conclude that low protein intake may hold the key to a long and healthy life, at least until old age. They also emphasize the need to examine not only calories when deciding what constitutes a healthy diet, but also where those calories come from - such as whether protein is animal or plant-based. Another key finding is the suggestion that while a high-protein diet may in the short term help people lose weight and body fat, in the long term it may harm health and reduce lifespan. Both studies are published in the journal Cell Metabolism.
The first study was led by Valter Longo, a professor at the University of Southern California, who counts longevity and cell biology among his areas of expertise.
He and his colleagues showed that high protein consumption is linked to increased risk of cancer, diabetes and death in middle-aged adults, although this was not the case for older adults who may benefit from moderate protein consumption. Also, the effect is much reduced when the protein comes from plant sources.

Cinnamon could fight Parkinson's

Cinnamon could be a secret weapon in the battle against Parkinson’s disease. Scientists have found that the spice is the source of a chemical that can protect the brain. Our liver converts cinnamon into sodium benzoate, an approved drug used in the treatment for neural disorders. 
In a study of mice at Rush University Medical Centre in Chicago, a team of researchers found that the chemical then enters the brain, stops the loss of proteins that help protect cells, protects neurons and improves motor functions.

Lead researcher Professor Kalipada Pahan told the Journal of Neuroimmune Pharmacology: ‘Cinnamon has been used widely as a spice throughout the world for centuries. This could potentially be one of the safest approaches to halt disease progression in Parkinson’s patients.’
Professor Pahan said tests had shown that Ceylon cinnamon is better at halting Parkinson's as it is more pure.
