Researchers have found that the part of the brain believed to be integral to learning, memory and mental health is smaller in people who consume unhealthy foods regularly.

Although the study was conducted in adults over 60 years of age, the researchers believe that the findings are relevant for people of all ages, including children. "We have known for some time that components of diet, both healthy and unhealthy, have a rapid impact on aspects of the brain that affect hippocampal size and function, but up until now these studies have only been done in rats and mice,” said lead study author Felice Jacka, associate professor at Deakin University School of Medicine in Geelong, Australia. "This is the first study to show that this also appears to be the case for humans,” Jacka noted. The researchers used magnetic resonance imaging to measure the size of hippocampi (there are two in the brain - left and right) in Australian adults aged 60-64 years. Older adults who ate more unhealthy foods, such as sweet drinks, salty snacks and processed meats, had smaller left hippocampi, the findings showed. Those who ate more nutrient-rich foods, such as vegetables, fruits and fish, had larger left hippocampi. These findings have relevance for both dementia and mental health, Jacka said. "As the hippocampus is critical to learning and memory throughout life, as well as being a key part of the brain involved in mental health, this study underscores the importance of good nutrition for children, adolescents and adults of all ages,” she pointed out. The study was published in the journal BMC Medicine.
