Two large studies found a link between high consumption of ultra-processed foods and increased risks of cardiovascular disease, bowel cancer, and death. The findings support policies limiting ultra-processed foods and promote eating unprocessed or minimally-processed foods for improved public health.
A recent investigation by The BMJ reveals that hospital trusts in England are bracing for a significant increase in energy bills this winter, with some anticipating a rise of over 200% in fuel costs. This would result in reduced patient care and staffing levels, posing a major challenge to the NHS's ability to operate effectively.

Researchers found a lower concussion rate in Florida, where headgear was mandated, compared to states without. The rate was 0.39 concussions/1000 athlete exposures with mandatory headgear, vs 0.44 without. This suggests that headgear may be worth considering for high schools and other levels of play.
