Higher intakes of black tea, berries, citrus fruits and apples could help to promote healthy ageing, new research has found.

This study conducted by researchers from Edith Cowan University, Queen’s University Belfast and Harvard T.H. Chan School of Public Health, found that foods rich in flavonoids could help to lower the risk of key components of unhealthy ageing, including frailty, impaired physical function and poor mental health.

“The goal of medical research is not just to help people live longer but to ensure they stay healthy for as long as possible,” ECU Adjunct Lecturer Dr Nicola Bondonno said.

“We know from previous research that people who have a higher flavonoid intake tend to live longer, and they are also les...

University of Michigan researchers have discovered that oxidative stress experienced early in life increases subsequent stress resistance later in life. Oxidative stress happens when cells produce more oxidants and free radicals than they can deal with. It’s part of the aging process, but can also arise from stressful conditions such as exercise and calorie restriction.

Examining a type of roundworm called C. elegans, U-M scientists Ursula Jakob and Daphne Bazopoulou found that worms that produced more oxidants during development lived longer than worms that produced fewer oxidants. Their results are published in the journal Nature.

Scientists discover new protection against oxidative stress. Ageing and a low life expectancy are caused, at least partly, by oxidative stress. A team of researchers led by Prof. Dr. Ivana Ivanovi-Burmazovi from the Chair of Bioinorganic Chemistry at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), together with researchers from the USA, have discovered that zinc can activate an organic molecule, helping to protect against oxidative stress.

Zinc is a trace mineral we need in order to remain healthy. FAU researchers working together with Prof. Dr...

porcini mushrooms

Mushrooms may contain unusually high amounts of two antioxidants that some scientists suggest could help fight aging and bolster health, according to a team of Penn State researchers. In a study, researchers found that mushrooms have high amounts of the ergothioneine and glutathione, both important antioxidants, said Robert Beelman, professor emeritus of food science and director of the Penn State Center for Plant and Mushroom Products for Health. He added that the researchers also found that the amounts the two compounds varied greatly between mushroom species. “What we found is that, without a doubt, mushrooms are highest dietary source of these two antioxidants taken together, and that some types are really packed with both of them,” said Beelman...
