Scientists reveal that switching from an African heritage diet to a Western-style diet for two weeks causes inflammation, reduces the immune response to pathogens, and activates processes associated with lifestyle diseases. Meanwhile, consuming an African diet rich in vegetables and fiber or a traditional fermented banana beverage had a predominantly anti-inflammatory effect.The team from Radboud University Medical Center in the Netherlands and KCMC University in Tanzania conducted a randomized controlled trial with 77 healthy men from Tanzania. The group consisted of urban residents, who typically consume a Western-style diet higher in processed foods, and rural dwellers, who consume a more traditional African diet.
