A study published in the Journal Brain, Behaviour and Immunity, found that four weeks on a diet of highly processed food can lead to a strong inflammatory response in the memory in aging brains and may cause Alzheimer’s in some people.
The researchers also found that replacing processed foods with omega-3 fatty acid DHA prevented memory problems and reduced the inflammatory effects in older rats. However, neuroinflammation and cognitive problems were not detected in young adult rats that ate the processed diet.
Abrupt memory deficit and rapid memory decline in older people are some of the other disadvantages of a highly-processed diet, reported by the researchers in their findings. It was also found that it may affect the brain and can be a cause of Alzheimer’s.
The 3-month-old and 24-month-old male rats were taken to conduct the test and assigned a highly-processed diet or the same processed diet supplemented with DHA. The activation of genes led to a powerful pro-inflammatory protein and various other substances that contribute to inflammation.
Ruth Barrientos, an investigator in The Ohio State University Institute for Behavioral Medicine Research and associate professor of psychiatry and behavioral health said “the fact we’re seeing these effects so quickly is a little bit alarming. we can limit processed foods in our diets by being aware of the cause and can also increase consumption of foods that are rich in the omega-3 fatty acid DHA in the diet.”
