This paper explores the relationship between various dietary factors, including diet and lifestyle, and longevity and other key health outcomes. The study uses data from the Global Dietary Database and the Global Change Data Lab. In terms of life expectancy, the study concludes that increasing intake of starchy vegetables, cheese, sodium, selenium, vitamin B3, and zinc while decreasing intake of potatoes, red meat, protein, iron, and vitamin B1 can increase life expectancy. However, the paper acknowledges that more research is needed to confirm some of these findings, and that confounding factors such as food preparation techniques and dietary groups should be controlled for in future analyses. The study found that increasing intake of starchy vegetables, seafood, and selenium, and decreasing intake of carbohydrates, iodine, and vitamin B12 can improve fertility in women. The research also suggests that decreasing consumption of beans and legumes, cheese, sugary beverages, and iodine, as well as limiting use of cellular subscriptions, can reduce the risk of Alzheimer's and dementia. Additionally, the study highlights that increasing intake of non-starchy vegetables, potatoes, protein, and vitamin B6 can also help decrease the chances of these neurological conditions. Overall, this research provides valuable insights into the relationship between diet and lifestyle factors and life expectancy. The study's findings can inform public health policies and interventions aimed at improving health outcomes, particularly in terms of fertility, Alzheimer's and dementia, and life expectancy.
