 [SCZ]Fatty Acids, Intelligence and Cognitive Decline |

It’s no secret that fatty acids are key building blocks to a healthy brain. What you may not know is that certain fatty acids have been shown to actually boost intelligence and an imbalance of fatty acids may be linked to hyperactivity, depression, brain allergies, and schizophrenia. Find out the hidden secrets of fatty acids here.
Imbalance of Fatty Acids and Mental Disorders
Some researchers believe an imbalance of omega-3 and omega-6 fatty acids may lead to a variety of mental disorders, including hyperactivity, depression, brain allergies, and schizophrenia. A balanced ratio of the two fatty acid families (omega-3 and omega-6) is necessary for a healthy brain, which is structurally composed of a 1:1 ratio of omega-6 to omega-3. Western diets, however, tend to have at least twenty times more omega-6 fats (from meat and dairy) than omega-3 fats–an unhealthy ratio of 20:1.
This imbalance can be corrected by eating more omega-3-rich fish and flax seed oil, by eating less sugar, and by completely avoiding trans fatty acids found in partially-hydrogenated oils, margarine, and shortening. In fact, to err on the side of safety, avoid "supermarket" oils and salad dressings unless they are clearly labeled "cold-pressed" – or in the case of olive oil, "extra virgin."
Fatty Acids Boost Intelligence-Study
Adding DHA (docosahexaenoic acid) and AA (arachidonic acid) to infant formula significantly boosted the average intelligence scores in a group of children, according to a 2000 study funded by the U.S. National Institute of Child Health and Human Development.
The study tested the intelligence scores of 56 infants, 18 months old. One group received formula containing only DHA, while another received one containing DHA and AA. The control group's commercial formula did not contain either substance. All three groups of infants were enrolled in the study within five days of their birth, and for 17 weeks received one of the three formulas.
When the children's overall intelligence was tested, they differed significantly on the Mental Development Index (MDI) that measures young children's memory, their ability to solve simple problems, and their language capabilities.
The children in the control group received an average MDI score of 98 – slightly below the national average of 100 for U.S. children. The DHA group received an average score of 102.4, and the DHA plus AA group received an average score of 105.
DHA for Higher IQs
An 18-year study concluded that (docosahexaenoic acid) DHA was the likely breast milk nutrient that provided the improved academic outcome experienced by breast-fed children.13
Mother's milk is high in DHA, and children who receive adequate amounts of DHA were shown to have higher IQs, as well as better vision than children who didn't get enough DHA.14 | |
