Although thirst and hunger have historically motivated drinking and feeding, respectively, the high and increasing consumption of energy-yielding beverages and energy-diluted foods may have degraded the predictive value of these sensations on ingestive behavior. Our within subject (ie, multiple responses from the same individuals), observational (ie, free-living, with no intervention) study explored the relationships between thirst, hunger, eating, and drinking patterns in 50 weight-stable adults (39 women and 11 men aged 30+/-11 years with body mass index 26.3+/-5.9). Twenty-four-hour dietary recalls were obtained for a consecutive 7-day period. ⋯ Further, energy-yielding beverages were the main contributor to fluid intake during both periprandial and drink-only events. These data fail to reveal associations between either thirst or hunger and ingestion of energy-yielding beverages, or strong associations between hunger and eating or thirst and drinking. These data raise questions about the predictive power of appetitive sensations for ingestive behavior.

Fruits and vegetables, foods rich in flavonoids and antioxidants, have been associated with lower risk of stroke, coronary heart disease, and markers of inflammation and oxidative stress in adults. Markers of inflammation and oxidative stress are predictors of coronary heart disease risk; however, it is unknown whether these markers are related to dietary flavonoid and antioxidant intake in youth. ⋯ Study results show that the beneficial effects of fruit and vegetable intake on markers of inflammation and oxidative stress are already present by early adolescence and provide support for the Dietary Guidelines for Americans "to consume five or more servings per day" of fruits and vegetables to promote beneficial cardiovascular health.

Concerns about the diets of school-aged children and new nutrition recommendations for the US population have increased interest in the nutritional quality of meals available through the National School Lunch Program and School Breakfast Program. ⋯ For school meals to meet nutrient standards and promote eating behaviors consistent with the Dietary Guidelines, future policy, practice, and research should focus on reducing levels of fat and sodium and increasing fiber.

Rates of overweight and obesity have increased dramatically during the past 2 decades. Children obtain a large fraction of their food energy while at school. ⋯ There was no evidence that either the school breakfast or lunch program is contributing to rising rates of childhood obesity. In fact, School Breakfast Program participation may be a protective factor, by encouraging students to consume breakfast more regularly.
