Sugar in green tea is a healthy idea

Mario Ferruzzi, lead researcher and associate professor of food science and nutrition at Purdue University, insists that adding ascorbic acid to green tea would increase the absorbability of catechins found in the tea.

Catechins, a class of polyphenols common in tea, cocoa and grape, are antioxidants thought to fight heart disease, stroke, cancer, diabetes and other health problems.
Ascorbic acid, sucrose or both together increase by as much as three times the amount of catechins that can be absorbed into the bloodstream.

The new study also demonstrates the effectiveness of a model that could reduce the number of animals needed for these types of studies. The model charts how the digestive stability, solubility and absorption of polyphenols changes based on modifications to a beverage’s formula.

Ferruzzi said testing with the model could allow researchers to predict how a new product formula might change the product’s properties, reducing the number of animals needed for testing to only products that showed desired characteristics in the model.

Gap between babies and cancer
Having a second child within a year of the first birth can increase a woman’s risk of developing breast cancer, finds a new study. The research, involving 30,000 women each of whom had produced five or more children, has shown that those with a gap of less than 12 month were 5.2 times more likely to develop the advanced ductal breast cancer than women who had a gap of three or more years.

Although it is unclear that why the risk increases, researchers believe hormones might be involved. Alternatively, other risk factors may have influenced the results, including being overweight, and whether or not the mother chooses to breast-feed.

13yr-old UK girl hit by dementia
She is just 13 years old, but displays the same symptoms as a 70-year-old suffering from Alzheimer’s disease. Stuck down by the early onset of dementia at this tender age, Isobel Jeffery can no longer feed or dress herself or walk or talk properly.

The little schoolgirl, Exeter, Devon, has lost the ability to concentrate or hold a conversation. She suffers memory loss, nightmares, hallucinations, and becomes easily confused.

However, still, her parents describe her as a ‘rare cookie’ with a “wicked sense of
humour and enthusiasm about life”. They have revealed that Isobel was diagnosed with early-onset dementia when she was nine, after she had begun to slur words, and display the same problems as people eight times her age. She was losing the ability to swallow and was unsteady on her feet at the time, they say.

Passive smoking affects liver
People can develop liver disease even when they are exposed to second-hand tobacco smoke, according to a study.

Scientists at the University of California, Riverside (UCR) have found that exposure to second-hand tobacco smoke can lead to non-alcoholic fatty liver disease (NAFLD), a common disease and rising cause of chronic liver injury wherein fat accumulates in the liver of people who drink little or no alcohol.

For their study, the researchers exposed some mice to second-hand cigarette smoke for a year in the lab, and observed fat build-up in their liver cells, a sign of NAFLD that eventually leads to liver dysfunction.
