Children with ADHD may have an Iron Deficiency
Children with attention deficit and hyperactive disorder (the disorder normally treated with Ritalin) may have iron deficiency according to this new study. Low levels of iron can decrease the activity of dopamine, an important neurotransmitter n the brain, and because of this it may contribute to the pathophysiology of ADHD - in other words low levels of iron can contribute to the overall symptoms of ADHD. In this study 53 children with ADHD had their levels of iron compared to those of 27 children who were ADHD free. 84% of the children with ADHD had low levels of ferritin, a measure of iron, versus 17% of the non-ADHD children. Additionally, the lower the level of ferritin, the more severe the symptoms of ADHD became.The researchers state that children with ADHD may benefit from iron supplementation and this may decrease the amount of prescription medication they may need. The study is published in the December 2004 issue of the journal Archives of Pediatrics and Adolescent Medicine.
Vitamins, Minerals, and Protein Declining in Fruits and Vegetables
Compared with 50 years ago, todays fruits and vegetables contain lower amounts of many important nutrients including Calcium and Vitamin C. Previous studies from the US and United Kingdom also show this trend towards a decline in important vitamins and minerals in foods in recent years.
In the new study scientists measured the amount of 13 key nutrients in 38 vegetables, 3 melons, tomatoes and strawberries and compared them to their levels in 1950. There is an apparent drop in the amount of protein, calcium, vitamin C, vitamin B2, phosphorus and iron in todays produce versus yesterdays. Protein, the least affected of the declining nutrients, fell by 6%, and vitamin B2, the most affected dropped by a whopping 38%. The study is published in the December 2004 issue of the Journal of the American College of Nutrition.
Gamma-Tocopherol Kills Prostate Cancer and Lung Cancer Cells
Gamma-Tocopherol appears to fight prostate cancer and lung cancer without harming healthy cells. Previous studies have shown that Alpha-Tocopherol has cancer fighting ability but only in the presence of a good amount of Gamma-Tocopherol.
In this new study researchers at Purdue University wanted to test the cancer fighting ability of Gamma-Tocopherol. Previously these scientists found that Gamma-Tocopherol has anti-inflammatory activity. In this study they added Gamma-Tocopherol to human prostate cancer and human lung cancer. Gamma-Tocopherol was amazing. It inhibited the spread of prostate cancer and lung cancer but didn't hurt healthy cells. This indicates that Gamma-Tocopherol may combat cancer without damaging normal cells.
Gamma-Tocopherol interfered with the cell membrane of cancer cells and this effect was fatal destroying the cancer cells without damaging healthy tissue. The Gamma-Tocopherol worked even better when other forms of vitamin E were added to it.
The researchers say it may not be a good idea to feast on Gamma-Tocopherol containing foods because they are rich in other oils and they are fattening. Some of these foods carry additional hazards, for instance corn oil is rich in certain fats that cause inflammation and promote certain cancers in some studies. The researchers say that Gamma-Tocopherol containing supplements in appropriate amounts might help high risk groups such as older men in danger of developing prostate cancer. The study was announced in a news release by Purdue University, and will appear in the print edition of the December 21st, 2004 issue of the Proceedings of the National Academy of Sciences.
