Why a walk in the park beats a stroll on the street

Singapore Botanic Gardens

Older adults who take a daily constitutional may want to avoid traffic-jammed city streets and head to a park instead because polluted air diminishes the benefits of exercise, a UK study suggests.

Researchers in London randomly assigned 119 men and women age 60 or older to take two-hour walks along one of two distinct routes: Through a tranquil traffic-free expanse of Hyde Park, or along Oxford Street, the city’s bustling shopping district that’s clogged with diesel-powered buses and cabs.

After walking in Hyde Park, healthy participants had better lung capacity and decreased arterial stiffness, the study found. But when these people walked along Oxford Street, they experienced only a slight improvement in lung capacity and their arteries got stiffer.

“Just walking at a normal pace for a couple of hours benefits the respiratory and cardiovascular system for up to 24 hours after the walk,” said senior study author Kian Fan Chung of Imperial College London.

Eating apples or tomatoes each day can repair damaged lungs caused by SMOKING and natural aging


Eating three apples a day slows down the natural aging of the lungs and repairs damage caused by smoking, a study concludes.

Researchers from Johns Hopkins Bloomberg School of Public Health found the same life-extending benefits are achieved from consuming two tomatoes each day.

However, the protective effects stems only from fresh varieties - meaning canned or processed tomatoes and apples don't work.

Natural decline in lung function over 10 years was slower among former smokers with a diet high in tomatoes and fruits, especially apples.

Exceptional people: From a PSLE score of 181 to NUS Medicine


Mr Tan Jun Xiang, 22, is not your typical medical student who aced all his school examinations.

In fact, he scored only 181 points in the PSLE and had to go into the five-year Normal stream in secondary school.

So the polytechnic graduate, who made it to the prestigious medicine faculty at the National University of Singapore (NUS), is among the rare few who do not fit the mould.

I tell others: "Don't give up, just aim high and don't compare yourself to others. You will never know what may happen."

Scientists reveal why this ONE salad dressing could help fight dementia

Drinking blueberry vinegar – or using it in salad dressings – could stave off dementia, new research suggests.

The condiment, which is produced by allowing the fruit to sour, is rich in a brain boosting chemical, according to scientists.

Experiments found the memory of mice with amnesia returned after they were fed the fermented product.

After consuming it, they had more of a protein that fuels nerve cells, as well as increased levels of a compound that is destroyed in dementia patients.
