Exercise may slow brain ageing in older adults
Regular walking, gardening, swimming and dancing may slow brain ageing and prevent brain shrinkage in older adults, say researchers. The study used magnetic resonance imaging (MRI) scans to measure the brains of people with a range of activity levels, including those who were inactive to those who were very active. The scans showed less active people had smaller brain volume, the researchers said. “These results are exciting, as they suggest that people may potentially prevent brain shrinking and the effects of ageing on the brain simply by becoming more active,” said study author Yian Gu from Columbia University in the US.
Egg and heart disease risk
Moderate consumption of eggs — up to one per day — is not associated with an increased risk of heart disease, according to a review of studies which may lead to new dietary recommendations. The study provides compelling evidence supporting the lack of an appreciable association between moderate egg consumption and cardiovascular disease.
