Can fluoride be harmful to health? If so, how?: While generally safe at recommended levels, excessive fluoride intake can lead to health problems, including dental fluorosis (white spots on teeth) and, in severe cases, skeletal fluorosis and kidney damage. The dose of fluoride determines its toxicity.
Does fluoride exposure affect children's intelligence?: Studies on the link between fluoride and reduced intelligence in children show conflicting results. Some research suggests a possible negative correlation at high fluoride levels, while others find no significant effect at recommended levels. More research is needed to definitively conclude the impact of fluoride on cognitive development.
Why is fluoride added to drinking water and other products?: Fluoride is added to drinking water and dental products to prevent tooth decay due to its proven effectiveness in reducing cavities. This practice is widely considered a major public health achievement, though it remains controversial.
What is fluoride and what are its benefits for dental health?: Fluoride is a naturally occurring element found in various sources, including water, food, and dental products. It's crucial for dental health, promoting remineralization of tooth enamel and reducing cavities.
What are the main arguments for and against water fluoridation?: Robert Kennedy Jr.'s advocacy against water fluoridation highlights ongoing debates about the safety and efficacy of fluoride. While public health organizations support fluoridation, concerns about potential health risks and environmental impacts persist, leading to varied regulations and public opinion worldwide.

Physical Fitness Linked to Lower Cancer Mortality Risk

A study of nearly 47,000 cancer patients found that muscular strength and cardiorespiratory fitness were associated with a 31–46% lower risk of death from any cause, with even greater reductions in specific cancer types and stages; this research, published in the British Journal of Sports Medicine, suggests tailored exercise plans may improve survival rates.
