Sardines are high in omega 3 fatty acids, a polyunsaturated fat that seems to offer protection against both heart disease and cancer. Since most Americans don’t get enough omega 3’s, these relatively inexpensive and easy to find canned wonders could be a nutrition gold mine.
In addition to the healthy fats and protein, sardines are a good source of calcium, iron, zinc and selenium. Calories are just slightly higher than salmon.
Twelve to 18 percent of children and adolescents aged 2 to 19 are obese and are at high risk for type 2 diabetes, asthma and even nonalcoholic fatty liver disease. Obesity also increases risk for certain cancers – so the long term consequences are serious. Identifying these high risk children is only the first step in making a difference. The second part of the recommendation – referring them to appropriate programs – is really the key to this report.
The Task Force reviewed over a dozen studies on behavioral programs targeted to overweight and obese children and adolescents. They found that comprehensive programs using counseling, physical activity programs and behavioral management techniques were successful for modest weight loss that continued for at least 12 months after the program ended.
There are successful models and programs around the country for children and adolescents who struggle with overweight and obesity. But in areas where these programs aren’t available, what will the clinicians do once they’ve identified at risk children?
Hopefully this report will help spur the growth of effective comprehensive programs that involve the entire family so that any lifestyle and behavioral change made by the child will be sustainable.
What do you think of the new recommendations? Do you know of any comprehensive programs for children or adolescents in your community?
In the first study participants who reported moderate exercise during midlife or later life were less likely to have MCI. The authors suggest this may be due to production of nerve-protecting compounds, greater blood flow to the brain or other neuronal and cardiovascular benefits. Although people who are more physically active could also “show the same type of discipline in dietary habits, accident prevention…compliance with medical care and similar health-promoting behaviors.”
The second study followed 29 participants (average age 70) with MCI. Those randomly assigned to an exercise group, completed 4 days per week of 45 to 60 minutes of vigorous aerobic activity. The control group did stretching exercises, but maintained low heart rates.
The vigorous exercisers showed improved cognitive function compared to the control group. The authors point out that this would be a cost-effective practice to improve cognitive performance without the adverse effects of many drug therapies.
