Dietary Effects of Free School Breakfast for All Children Offering free school breakfasts to all elementary school students regardless of income increases the likelihood that the children will consume a nutritionally sound breakfast, according to researchers at the U.S. Department of Agriculture and Abt Associates, Inc.
The researchers spent three years tracking the dietary intakes of more than 4,300 students in second through sixth grades at 153 elementary schools. The study looked at the effects of offering "universal-free" school breakfast, or free breakfast to any student regardless of family income, in elementary schools on students' breakfast consumption and their total food and nutrient intake throughout the day compared with students at schools who participate in the federal government's School Breakfast Program that offers free or reduced-priced breakfast for children from families below the poverty level.
On average, the students receiving universal-free school breakfasts consumed less cholesterol than students in the School Breakfast Program. However, the study found no significant differences in the children's total daily dietary intakes, the overall quality of their diets or rates of "breakfast skipping" among children in either group.
"Students who cannot eat breakfast at home should have the opportunity to eat it at school," The researchers write. "This study and others have shown that improvements in children's nutrient intake are needed, particularly with regard to food energy, fat, sodium and fiber, as well as calcium for older children."
Cocoa Flavanol-Enriched Snack Bars Containing Phytosterols May Lower Total and LDL Cholesterol In the wake of evidence that indicates sterol esters and plant stanol esters may reduce a person's risk of coronary heart disease by lowering blood cholesterol levels, researchers at the University of California – Davis say consuming "phytosterol-enriched" cocoa-flavored snack bars as part of a balanced diet can help manage cholesterol.
Many food products containing plant sterols are now commercially available, including enriched margarines, milk and orange juice. The purpose of this study was to evaluate "alternative dietary means" to lower blood cholesterol "before prescribing pharmacological treatment."
Participants in the study were divided into two groups of adult men and women with blood cholesterol levels over 200. One group of 32 consumed two cocoa snack bars enriched with plant sterols per day for six weeks, and the other group of 35 people consumed snack bars that were not enriched. The researchers found what they termed significant reductions of 4.7 percent in total cholesterol and 6 percent in LDL-cholesterol levels in the group that consumed the flavanol-enriched snack bar with plant sterols.
"The data suggests the incorporation of this snack food into a balanced diet represents a practical dietary strategy in the management of cholesterol," the researchers write.
The study was funded in part by Masterfoods USA, a division of Mars Incorporated.
American Dietetic Association Issues Updated Position Statement on "The Roles of Registered Dietitians and Dietetic Technicians, Registered, in Health Promotion and Disease Prevention" A healthful diet and exercise are important factors in the promotion and maintenance of good health throughout the life cycle according to an updated ADA position statement published this month: It is the position of the American Dietetic Association that primary prevention is the most effective, affordable course of action for preventing and reducing risk for chronic disease. Registered dietitians and dietetic technicians, registered, are the leaders in delivering preventive services in both clinical and community settings, including advocating for funding and inclusion of these services in programs and policy initiatives at local, state and federal levels. In addition, registered dietitians are the leaders in facilitating and participating in research in chronic disease prevention and health promotion.
