Adults who skip morning meal miss out on nutrients, study finds.
Adults who skip breakfast are likely to miss out on key nutrients that are most abundant in the foods that make up morning meals, a new study suggests.
An analysis of data on more than 30,000 American adults showed that skipping breakfast — and missing out on the calcium in milk, vitamin C in fruit, and the fiber, vitamins and minerals found in fortified cereals — likely left adults low on those nutrients for the entire day.
“What we’re seeing is that if you don’t eat the foods that are commonly consumed at breakfast, you have a tendency not to eat them the rest of the day. So those common breakfast nutrients become a nutritional gap,” said Christopher Taylor, professor of medical dietetics in the College of Medicine at The Ohio State University and senior author of the study.
According to the U.S. Department of Agriculture’s latest dietary guidelines, calcium, potassium, fiber and vitamin D are considered “dietary components of public health concern” for the general U.S. population — with iron added for pregnant women — because shortages of those nutrients are associated with health problems.
Most research related to breakfast has focused on the effects of the missed morning meal on children in school, which includes difficulty focusing and behavioral problems.
“With adults, it’s more like, ‘You know how important breakfast is.’ But now we see what the implications really are if they miss breakfast,” Taylor said.
He completed the study with Ohio State School of Health and Rehabilitation Sciences graduate students Stephanie Fanelli and Christopher Walls. The research, which was supported by a regional dairy association, is published online in Proceedings of the Nutrition Society.
The team used data from the National Health and Nutrition Examination Survey (NHANES), which collects health information on a nationally representative sample of about 5,000 people every year through interviews, laboratory tests and physical exams.
The sample for this study included 30,889 adults age 19 and older who had participated in the survey between 2005 and 2016. The Ohio State researchers analyzed data from 24-hour dietary recalls participants completed as part of the NHANES survey.
“During the recall, participants self-designate their eating occasions as a meal or a snack, and they tell you at what point in time they ate whatever food they report,” said Fanelli, first author of the study. “That’s how we determined whether someone was a breakfast eater or a breakfast skipper.”
In this sample, 15.2% of participants, or 4,924 adults, had reported skipping breakfast.
The researchers translated the food data into nutrient estimates and MyPlate equivalents using the federal Food and Nutrient Database for Dietary Studies and daily dietary guidelines, and then compared those estimates to recommended nutrient intakes established by the Food and Nutrition Board of the National Academies.
On several key recommendations measured, from fiber and magnesium to copper and zinc, breakfast skippers had taken in fewer vitamins and minerals than people who had eaten breakfast. The differences were most pronounced for folate, calcium, iron, and vitamins A, B1, B2, B3, C and D.
“We found those who skipped breakfast were significantly more likely not to meet the bottom threshold of what we hope to see people eat,” Fanelli said.
Compared to the Healthy Eating Index-2015, which assesses how well a set of foods aligns with federal recommendations, breakfast skippers also had an overall lower-quality diet than those who ate breakfast.
For example, breakfast skippers were more likely than those who noshed in the morning to eat more added sugars, carbohydrates and total fat over the course of the day — in part because of higher levels of snacking.
“Snacking is basically contributing a meal’s worth of calorie intakes for people who skipped breakfast,” Taylor said. “People who ate breakfast ate more total calories than people who didn’t eat breakfast, but the lunch, dinner and snacks were much larger for people who skipped breakfast, and tended to be of a lower diet quality.”
While the data represent a single day in each participant’s life, the huge sample provides a “nationally representative snapshot for the day,” Taylor said.
“It shows that those who skipped breakfast had one nutrient profile and those who ate breakfast had a different nutrient profile,” he said. “It helps us identify on any given day that this percentage of people are more likely to be skipping breakfast. And on that day, their dietary intake pattern showed that their consumption didn’t capture those extra nutrients that they have basically missed at breakfast.”

This is true for people who cannot understand what is a vitamin. For the rest of us, we can just take a good daily multi-vitamin pill, with exponentally more nutrition. We can also drink a 45-60g vegetable protein smoothie, and significantly reduce our carbon footprint. (Uhhh… what’s a gram??? I want my burger!)
Consuming 3 meals a day is a bad plan, leading to obesity and the associated diseases. Two meals a day is just fine. One is fine as well.
This article and study, funded by big cereal 🙄
Every time you eat you spike insulin, causing you to gain weight or keep you from losing weight. Plan your meals closer together. The longer you “fast” the better your chances of losing weight. And don’t skip on the healthy fats, otherwise you will feel hungry all day. Skip breakfast for weight loss.
Thanks for reviving for so many clichés in a single article. Forget about fresh fruits and vegetables, we need some good fortified dairies and cereals – any good nutritionist from the seventies knows that.
I, for one, always considered breakfast very important after waking up in the morning. My children grew up on breakfast. It was either cereal, grits, bacon, sausage and eggs, juice. I believe this was the reason behind schools starting breakfast. My daughters did amazingly well in school because the brain was nourished and they got a good night’s rest. They are grown now,have careers and still having their breakfasts.
Ridiculous! I have celiac…not touching these cereals and Im still alive…lol
DO NOT TOUCH 99% of junk cereals with all the added sugar. DO NOT FEED MOST JUNK FOOD CEREALS TO YOUR KIDS, UNLESS you don’t like your kids or you are punishing them.
