The Overlooked Aspect: Snack Consumption in US Adults Equals a Meal in Calories

Snacking Habits

Recent research underscores that snacks, often nutritionally poor, contribute significantly to the daily calorie intake of American adults, comprising nearly one-fourth of it. It’s observed that individuals managing type 2 diabetes generally make healthier snack choices, indicative of the positive impact of dietary education.

The investigation reveals snacks offer minimal nutritional benefits.

A recent study indicates that in the United States, snacks make up nearly 25% of daily caloric intake for adults, contributing significantly to daily added sugar intake.

The analysis, which included over 20,000 participants, showed that American adults consume between 400 and 500 calories from snacks daily. This amount often surpasses the caloric intake from breakfast and is largely devoid of nutritional value.

Christopher Taylor, a professor at The Ohio State University and the study’s senior author, notes the significant impact of snacking habits, which are well-known to dietitians but not fully appreciated in terms of their magnitude.

Taylor explains, “Snacks add a meal’s worth of calories to our daily intake without being a complete meal. Unlike dinner, which typically includes a balance of protein and sides, snacks are mostly carbohydrates and sugars, lacking in protein, fruits, and vegetables, thus not constituting a well-rounded meal.”

Diabetes and Snacking Patterns

The study also examines the correlation between snacking habits and diabetes. Participants managing their type 2 diabetes tended to consume less sugar and snack less frequently than those without diabetes or those with prediabetes.

Taylor suggests that while diabetes education appears effective, there’s a need to extend educational efforts to those at risk of diabetes and even those with normal blood glucose levels, to foster healthier dietary practices before the onset of chronic diseases.

The findings were recently published in PLOS Global Public Health.

Study Methodology and Results

The research involved data from 23,708 U.S. adults, aged over 30, who participated in the National Health and Nutrition Examination Survey from 2005 to 2016. The survey included detailed 24-hour dietary recalls, providing insight into not only what was eaten but also when.

Participants were categorized based on their HbA1c levels into nondiabetic, prediabetic, controlled diabetic, and poorly controlled diabetic groups.

The study found that snacks contributed between 19.5% and 22.4% of total energy intake, offering minimal nutritional value. Snacks primarily included convenience foods rich in carbohydrates and fats, sweets, alcoholic and sugar-sweetened beverages, with a lower presence of protein, dairy, fruits, grains, and minimal vegetables.

Taylor notes the importance of these findings, stating that although a 24-hour food log may not represent typical eating patterns, it offers a valuable snapshot of a large population’s dietary habits, helping identify nutritional gaps and areas needing education.

The research also highlighted that individuals with diabetes tended to have healthier snacking habits, emphasizing the effectiveness of dietary education. Taylor stresses the need for broader education on healthier snacking patterns, not just reducing sugar and carbohydrates.

Broader Perspective on Snacking

Taylor advises a shift from focusing solely on reducing added sugars to adopting overall healthier snacking habits. He cautions against demonizing specific foods and emphasizes considering the broader nutritional picture. Removing certain items from the diet necessitates thoughtful replacements to maintain nutritional balance.

Taylor highlights the importance of planning snacks as part of the day’s overall diet, considering what is available at home and in the environment, especially during holiday seasons.

The study, titled “Snacks contribute considerably to total dietary intakes among adults stratified by glycemia in the United States,” was authored by Kristen Heitman, Sara E. Thomas, Owen Kelly, Stephanie M. Fanelli, Jessica L. Krok-Schoen, Menghua Luo, and Christopher A. Taylor. It was published on October 26, 2023, in PLOS Global Public Health, with support from Abbott Nutrition and Ohio State.
