Hyperlink between processed meals and cognitive decline
Within the multicenter, potential cohort examine, 10,775 members between the ages of 35 and 74 had been recruited from six totally different cities all through Brazil, together with Belo Horizonte, Porto Alegre, Rio de Janeiro, Salvador, São Paolo, and Vitoria.

Well being dangers of processed meats
This examine provides to a rising physique of analysis concerning the well being impacts of UPFs. One other examine revealed earlier this yr within the medical journal The BMJ discovered that top consumption of UPFs comes with an elevated danger of colorectal cancer in males.
