This week brings a mix of health news, from concerning predictions about future obesity rates to worries about bird flu and some positive news regarding air quality in London.
Obesity on the Rise
A recent study paints a concerning picture of future health trends. By 2050, experts predict that a staggering 60% of adults could be classified as overweight or obese. 
This alarming statistic has sparked warnings that global health systems will face immense pressure, particularly as a significant portion of the obese population will be over the age of 65.
This aging demographic within the obese population raises serious concerns about the strain on healthcare resources and the potential for increased chronic diseases. Preventative measures and public health initiatives are crucial to combat this growing epidemic.
Bird Flu and Cats: A Growing Concern
Another health concern making headlines is the potential for cats to contract and spread avian flu. Cats are susceptible to the virus, raising anxieties about the possibility of bird flu transmitting from stray and domesticated cats to humans, and ultimately, from human to human.
While the risk of human-to-human transmission remains low, the potential for the virus to mutate and become more easily transmissible is a significant worry. 
Further research and vigilance are needed to monitor the situation and prevent a potential outbreak. Pet owners are advised to take precautions and consult with their veterinarians if they have any concerns.
London Breathes Easier Thanks to ULEZ
In more positive news, a recent study has revealed that air pollution levels in London have decreased significantly since the expansion of the ultra low emission zone (Ulez) to outer boroughs. This is a welcome development for the health of Londoners, particularly those living in the capital’s most deprived areas.
"People in London have been breathing significantly cleaner air since the expansion of the ultra low emission zone (Ulez), a study has found."
The study found that levels of deadly pollutants linked to a range of health problems, from cancer to heart attacks, have dropped. 
This is particularly encouraging for the most deprived areas, where the improvements have been most pronounced. The ULEZ expansion appears to be having a tangible positive impact on public health in London, demonstrating the effectiveness of policies aimed at reducing air pollution.
In other news, the government has announced dedicated funding to expand toothbrushing supervision schemes in schools, targeting the poorest areas in England. This initiative aims to improve oral health among children and promote healthy habits from a young age.
