Some studies have indicated that there is an adverse relationship between lowering blood cholesterol levels by dieting and medication and emotional health of individual. Increases of depression, suicide and homicide have been linked to dieting. But it may not be hunger pangs that are influencing factor. The quantity and distribution of omega-6 and omega-3 fatty acids may play a significant role by influencing serum lipids and altering biophysical and biochemical properties of cell membranes. Epidemiological studies in various countries and in United States in recent years suggest decreased omega-3 fatty acid consumption correlates with increasing rates of depression. This is consistent with established relationship between coronary artery disease and depression. Omega-3 deficiency may also be related to depression associated with alcoholism, post-partum depression and multiple sclerosis.
What about attention-deficit hyperactivity disorder (ADHD)? It has become an epidemic in our time resulting in millions of children being placed on medication. In addition to fact that we are destroying attention spans of kids by placing them in front of televisions and computers instead of good books, there may be dietary influences as well.
A 1995 study involved 96 boys in Indiana schools, 53 of which had been diagnosed with ADHD. Dietary intake statistics of essential fatty acids were established based on 3-day surveys of each boy. There were no significant differences between ADHD boys and others in relation to consumption of protein, carbohydrates, vitamins and minerals. An additional 22 measurements were taken designed to establish lipid and fatty acid levels in each group.
It was found that ADHD group possessed significantly lower amounts of specific lipid fatty acids in plasma, and lower concentrations of total fatty acids in red blood cells than did non-ADHD group. Since omega-3 is primary polyunsaturated fatty acid found in retina and cerebral cortex it was postulated that low levels of omega-3 might negatively affect proper brain function and therefore ability to concentrate. What was not determined was whether omega-3 deficiencies were due to inadequate intakes of fatty acids or individual ability to metabolize them. In either case, however, higher intakes of omega-3 through eating fish or taking fish oil supplements could help to raise omega-3 levels and therefore help counteract to effects of ADHD.
