Omega-3 fatty acids â€” found in salmon, walnuts and kiwi fruit â€” provide many benefits, including improving learning and memory and helping to fight against such mental disorders as depression and mood disorders, schizophrenia, and dementia, said GÃ³mez-Pinilla, a member of UCLA’s Brain Research Institute and Brain Injury Research Center. . .
“Dietary deficiency of omega-3 fatty acids in humans has been associated with increased risk of several mental disorders, including attention-deficit disorder, dyslexia, dementia, depression, bipolar disorder and schizophrenia,” he said. “A deficiency of omega-3 fatty acids in rodents results in impaired learning and memory.”. . .
Preliminary results from a study in England show that school performance improved among a group of students receiving omega-3 fatty acids. In an Australian study, 396 children between the ages 6 and 12 who were given a drink with omega-3 fatty acids and other nutrients (iron, zinc, folic acid and vitamins A, B6, B12 and C) showed higher scores on tests measuring verbal intelligence and learning and memory after six months and one year than a control group of students who did not receive the nutritional drink. This study was also conducted with 394 children in Indonesia. . .
A long-term study that included more than 100 years of birth, death, health and genealogical records for 300 Swedish families in an isolated village showed that an individual’s risk for diabetes and early death increased if his or her paternal grandparents grew up in times of food abundance rather than food shortage.
“Evidence indicates that what you eat can affect your grandchildren’s brain molecules and synapses,” GÃ³mez-Pinilla said. “We are trying to find the molecular basis to explain this.”
Controlled meal-skipping or intermittent caloric restriction might provide health benefits, he said.
Excess calories can reduce the flexibility of synapses and increase the vulnerability of cells to damage by causing the formation of free radicals. Moderate caloric restriction could protect the brain by reducing oxidative damage to cellular proteins, lipids and nucleic acids, GÃ³mez-Pinilla said. . .
In patients with major depression and schizophrenia, levels of a signaling molecule known as brain-derived neurotrophic factor, or BDNF, are reduced. Antidepressants elevate BDNF levels, and most treatments for depression and schizophrenia stimulate BDNF. Here, too, omega-3 fatty acids are beneficial, as is the curry spice curcumin, which has been shown to reduce memory deficits in animal models of Alzheimer’s disease and brain trauma. BDNF is most abundant in the hippocampus and the hypothalamus â€” brain areas associated with cognitive and metabolic regulation.
The high consumption of curcumin in India may contribute to the low prevalence of Alzheimer’s disease on the subcontinent. . .
