Eating oily fish containing long chain seafood-derived omega-3 polyunsaturated fatty acids (PUFAs) protects against heart attacks and strokes. Hence most national and international guidelines now recommend that adults eat at least 2 servings per week of oily fish. However uptake of these recommendations is poor - many people do not eat seafood at all. A number of factors probably contribute to this poor compliance with guidelines; limited availability and costs of oily fish; distaste for oily fish; and concern about toxins in such fish. An Irish company, Devenish Nutrition, offers a possible alternative solution - by feeding omega-3 PUFA-enriched feeds to chicken, Devenish Nutrition have demonstrated that the resultant chicken meat and eggs are enriched in omega-3 PUFAs. A recently completed small study, with 30 participants, showed that 5 weeks of eating omega-3 PUFA enriched chicken resulted in increased blood levels of omega-3 PUFAs. There were also beneficial effects on blood pressure and on platelet stickiness. This study will be larger (including 160 participants) and longer in duration (6 months). It will be a double-blind, controlled, randomized study. This will allow testing whether eating omega-3 PUFA enriched chicken-meat regularly over a 6 month period, results in even greater increments in blood levels of omega-3 PUFAs, and in greater beneficial effects on cardiovascular risk factors. Beneficial effects of eating omega-3 PUFA enriched eggs will also be assessed.
A postprandial intervention study is conducted on healthy male subjects to evaluate whether the addition of proteins (why protein isolate, soy protein) can help to increase the bioavailability of carotenoids from a tomato/carrot beverage.
In prior research the Mobility and Vitality Lifestyle Program for healthy aging and weight management (MOVE UP) was effective in producing a mean loss of >= 5% body weight, with increased physical activity and reduced fatigue. This research will pilot a modified and streamlined version to see if it will be similarly effective for caregivers of family members or friends who have dementia, physical and/or developmental issues, or health problems.
This study investigates the aspects related to the intake of food and nutrients, physical activity and sedentary behavior of Spanish children from 1 to 9 years. Furthermore, the investigators will know if the consumption of dairy products is associated with a better dietary pattern. Hypothesis: The habitual consumption of dairy products as part of a regular diet is associated with a better dietary pattern and a higher global diet quality.
Through the internet and mobile phone SMS technology, and by using the Health Action Process Approach model as a theoretical backdrop, this 8-week theory-based intervention study aimed at developing a healthy lifestyle by supporting physical activity (PA) and a healthy dietary for Chinese university students. The investigators would examine whether the two intervention groups improve the participants' motivation for PA and healthy diets in comparison to the control group; whether, with the help of an intervention program, students are able to increase the PA levels and healthy diet consumption, and whether there are different effects between the two intervention programs.
Background: Eating too much processed food is believed to lead to obesity. But the effect of processed food on energy intake has not been carefully studied. Researchers want to study people s diets for 4 weeks and do specialized tests of the effects. Participants will get two diets. They will have the same calories and nutrients, but one diet will be unprocessed food and the other will be ultra-processed. Objective: To better understand how processed and unprocessed foods affect daily food consumption and how the body handles blood sugar. Eligibility: Healthy adults ages 18-50 who have stable weight and can exercise Design: Participants will not eat for 12 hours. Then they will be screened with: - Medical history - Physical exam - Heart and blood tests - Resting energy expenditure test (REE). A hood will collect air exhaled while lying down for 30-40 minutes. - Psychiatric questions - Questions about mood, eating, sleep, and socioeconomic status - 20-minute stationary biking Female participants will have a urine pregnancy test. Participants will stay in the clinic for 4 weeks. For 2 weeks they will get a processed diet. For the other 2 weeks they will get an unprocessed diet. Participants cannot use the study period to gain or lose weight. Participants will have: - Meals and snacks provided - Daily exercise - Blood, urine, and saliva tests - To drink a special water and a very sweet liquid - REE - Scans and X-rays - To wear activity monitors and a device to measure blood sugar - Several 24-hour periods in a room that measures oxygen and carbon dioxide - Repeats of screening questions - Questions about hunger and meals - Sleep monitoring - Taste tests
Because fruit and vegetables (FV) intake of children of Vitoria city is low, a controlled intervention program was proposed at school level. The intervention was based on the Theory of Planned Behavior (TPB) as long as behavioral theories have been proved to be the most effective changing infant FV intake pattern. The main purpose of the study is to evaluate the effectiveness of an intervention program based on TPB and aimed to increase FV consumption in schoolchildren aged 8 to 10. For that aim, eligible classrooms from different schools were randomly assigned to the intervention (n=86) or control (n=86) group. The intervention group received 14 sessions of 60 minutes during 9 months of an academic year. Sessions, designed by a multidisciplinary team, are based on TPB and aimed to modify determinants of behavior (attitudes, subjective norms, perceived behavioral control, intention of consumption), and intake of FV itself. Change in fruit and vegetable intake and determinants of eating behavior were evaluated at 9 months of intervention using validated surveys, 7 day food records, 24 hour reminders and questionnaires. This study will provide a valid and useful tool to achieve changes in the consumption of FV at school level. A negative result will be useful to help redefining new strategies in the framework of changing habits in the consumption of FV.
This study seeks to test the potential association between spermidine content in diet and mortality in humans.
An experimental trial will be conducted whereby a Supplemental Nutrition Assistance Program (SNAP)-like food benefit program will be implemented in 240 SNAP eligible households. Baseline and follow up measures will include three 24-hour dietary recalls; household food purchase receipt collection; and household food security questions. The individual level measures will be collected from the adult most responsible for food shopping and a child in the household. After baseline measures are completed households will be randomized to one of three conditions: 1) restriction (not allowed to buy sugar sweetened beverages, sweet baked goods, or candies with food benefits); 2) restriction paired with an incentive (30% financial incentive on fruits and vegetables and restriction of purchase of sugar sweetened beverages, sweet baked goods, or candy with food benefits); or 3) control (no incentive or restrictions). Households in all conditions will be given a debit card that will have funds added monthly for a five month period. The dollar amount placed on the card monthly will be similar to the amount the household would receive if enrolled in SNAP. All participants will be instructed to use the debit card for food purchases only, and they'll be told they shouldn't use the card to purchase items currently non-eligible for purchase with SNAP benefits (e.g. alcohol, food from restaurants). Those in the restriction condition will also be told they cannot use the card to buy sugar sweetened beverages, sweet baked goods, or candies. They may purchase these foods using their own money, but not the debit card. Those in the restriction plus incentive condition will receive the instructions provided to the restriction group plus they will be told that they'll receive a 30% bonus for fruits and vegetables purchased using their debit card. Analyses will determine whether the nutritional quality of the diet at follow-up differs between experimental groups.
