This study aimed to estimate the antioxidant intake from fruits and vegetables in the UK and Scottish population and to examine consumption models to identify potential strategies to optimize antioxidant intake from these foods. It’s a retrospective study of cross-sectional data on F&V intake in relation to antioxidant intake. Antioxidant capacity of individual fruits and vegetables was determined by the ferric reducing antioxidant power assay.
The number of bike-related deaths among children younger than 16 fell by more than half after a Canadian bike-helmet law went into effect, a new study shows.
Pregnant women who increase their fiber intake by 5 grams a day — the equivalent of 2 slices of whole grain bread — may reduce their risk of developing preeclampsia by about 14 percent, researchers report.
Borgerne i de velstillede kommuner nord for København ryger mindre, motionerer mere og lider ikke i samme omfang af kroniske sygdomme som borgerne i de mindre velstående kommuner på bl.a. Vestegnen.
Helt nye tal fra DTU Fødevareinstituttet viser, at 64% af de danske børn får mere end de maksimalt anbefalede 10% energi fra sukker. Både børn og vokse spiser og drikker i gennemsnit ca. tre gange så meget slik, chokolade, is, kage, sukkersødede drikke m.v., som der er plads til i en sund kost.
DTU Fødevareinstituttet har i dag offentliggjort deres nye rapport om danskernes kostvaner i perioden 1995-2006. De voksnes indtag af frugt og grønt er også steget fra 279 til 398 gram i perioden. Det er en stigning på 43%.
Adults with memory problems who participated in a home-based physical activity program experienced a modest improvement in cognitive function, compared to those who did not participate in the program, according to a study in the September 3 issue of JAMA.
Nicola T. Lautenschlager from University of Melbourne, Australia, and colleagues conducted a randomized controlled trial to test whether 150 minutes of moderate-intensity physical activity per week would reduce the rate of cognitive decline among 138 adults age 50 years and older at increased risk of dementia. The most frequently recommended type of activity was walking.
The researchers found that participants in the exercise group had better scores on an Alzheimer Disease Assessment Scale than those in the control group. Participants in the physical activity group also had lower Clinical Dementia Rating scores.
This trial is the first to demonstrate that exercise improves cognitive function in older adults with mild cognitive impairment.
School-based intervention programs provide the best results for reducing prevalence of childhood obesity if they are performed with involvement of stakeholders and political support. In this context physical activity education in schools, reducing television viewing and nutritional education are examples of interventions that have been successful.
Children burn more than four times as many calories per minute playing an active video game than playing a seated game, and their heart rate is also significantly higher with the active game, according to a new report in the September issue of Archives of Pediatrics & Adolescent Medicine.
The gaming industry has begun producing active “extertainment” gaming systems. “A recent active gaming concept that allows players to experience various activities (e.g., bowling, fishing, tennis, golf) in a virtual world is the XaviX gaming system. “In addition to the exercise gaming modalities, the XaviX system includes a gaming mat that allows participants to travel the streets of Hong Kong at a walk or a run, avoiding obstacles and stamping out ninjas.”
Researchers at University of Hong Kong measured heart rate and calorie expenditure in 18 children age 6 to 12 during a 25-minute gaming protocol. Participants rested for five minutes, then played a seated computer bowling game, an active bowling game and the action/running game for five minutes each, with five minutes of rest between active games.
Compared with resting, children burned 98 percent more playing active bowling and 451 percent more during the action/running game. “This translates into a more than four-fold increase in energy expenditure for the gaming mat. Preventing weight gain requires an energy adjustment of approximately 150 kilocalories per day. The four-fold increase in energy expenditure when playing on the gaming mat would fill the proposed energy gap, if this game were played for 35 minutes a day.
Big business has been accused of misleading children by distributing educational materials to schools about pupils’ diets which experts say are wrong and likely to encourage poor eating habits.
