A new study from Perth's Telethon Institute for Child Health Research shows an association between ADHD and a 'Western-style' diet in adolescents.
The research findings have just been published online in the International Journal of Attention Disorders.
Leader of Nutrition studies at the Institute, Associate Professor Wendy Oddy, said the study examined the dietary patterns of 1800 adolescents from the long-term Raine Study and classified diets into 'Healthy' or 'Western' patterns.
"We found a diet high in the Western pattern of foods was associated with more than double the risk of having an ADHD diagnosis compared with a diet low in the Western pattern, after adjusting for numerous other social and family influences," Dr Oddy said.

However, only one in three people who perceive a need for mental health services or are in serious distress have seen a professional for treatment, the survey found.
The survey was conducted among more than 44,000 adults as part of the 2005 California Health Interview Survey, administered through the UCLA Center for Health Policy Research. Since the survey was conducted, the recession probably has contributed to worsening mental health for even more people, said the lead author of the study, David Grant.

Phytochemicals (plant chemicals) are defined as bioactive non-nutrient plant compounds in fruits, vegetables, grains, and other plant foods that have been linked to reducing the risk of major chronic diseases including cancer.
Study shows such behavior makes men feel less stressed; women have opposite reaction
You might think that defensiveness - which psychologists describe as avoiding, denying, or repressing information one perceives as threatening - would not be a good thing, and maybe even causes you stress. But a new Canadian study finds men may actually feel better, and less stressed, when they are more defensive. By contrast, women are better off not feeling defensive.

If the findings of existing clinical trials hold up in future research, the potential consequences of this deficiency are likely to go far beyond inadequate bone development and excessive bone loss that can result in falls and fractures. Every tissue in the body, including the brain, heart, muscles and immune system, has receptors for vitamin D, meaning that this nutrient is needed at proper levels for these tissues to function well.
Studies indicate that the effects of a vitamin D deficiency include an elevated risk of developing (and dying from) cancers of the colon, breast and prostate; high blood pressure and cardiovascular disease; osteoarthritis; and immune-system abnormalities that can result in infections and autoimmune disorders like multiple sclerosis, Type 1 diabetes and rheumatoid arthritis.
Most people in the modern world have lifestyles that prevent them from acquiring the levels of vitamin D that evolution intended us to have. The sun's ultraviolet-B rays absorbed through the skin are the body's main source of this nutrient. Early humans evolved near the equator, where sun exposure is intense year round, and minimally clothed people spent most of the day outdoors.

Published in the July issue of Genetics, the study adds weight to the theory of personalised nutrition, which suggests that the benefit of nutritional compounds varies for different people.
"This study strongly suggests that some individuals can achieve benefits from altering their dietary habits, while the same changes for others will have virtually no effect," write the researchers.

Forests - and other natural, green settings - can reduce stress, improve moods, reduce anger and aggressiveness and increase overall happiness. Forest visits may also strengthen our immune system by increasing the activity and number of natural killer cells that destroy cancer cells.

In 2009, the U.S. Department of Agriculture (USDA) was involved in 59 recalls, said the Chicago Tribune. In all cases, the agency knew how much food was involved and how much was recovered; however, most - 56 recalls - did not tally up the complete amounts identified as problematic, said the Tribune.
Last year, a recall announced by a processor in Denver for 460,000 pounds of ground beef only turned up 119,000 pounds, leaving over 300,000 pounds of potentially dangerous meat on the market or in consumers' kitchens, said the Tribune. In that case, the pathogen was Salmonella and the beef was linked to an outbreak at the time. Later that year, another processor - this one in New York - announced a larger ground beef recall of 545,000 pounds linked to an outbreak of E. coli. According to the USDA, said the Tribune, only 795 pounds of the potentially tainted beef was ever recovered.

BPA levels higher than those in canned foods, baby bottles and infant formula were detected on at least one of several receipts from Chevron, McDonalds, CVS, KFC, Whole Foods, Safeway, the U.S. Postal Service, Walmart and the U.S. House of Representatives cafeteria, according to the private Washington-based research group.
Many large manufacturers of baby bottles now sell products that are free of the chemical BPA, or bisphenol-A.
Lansing - Michigan could save billions annually by protecting children from exposure to environmental hazards, according to a study released today.
The report released by an Ann Arbor-based coalition of health and environmental groups examined direct and indirect costs of four childhood diseases linked to environmental toxicants: lead poisoning, asthma, pediatric cancer and neurodevelopmental disorders.
The study found treating those disorders costs Michigan an average of $5.85 billion each year. If all diseases with an environmental link were included, the number would be higher.
