New scientific evidence suggests that the potential health gains achieved through nutritious main courses are often offset by the consumption of unhealthy snacks. While snacking itself is not fundamentally detrimental to health, the specific kind of snack and its timing are key factors.
A research paper published in the European Journal of Nutrition reveals that numerous individuals compromise the health advantages of their well-balanced meals by indulging in poor-quality snacks. The timing of these snacks, particularly after 9 p.m., has been shown to adversely affect one’s health.
Approximately 25% of people negate the positive effects of their nutritious meals by choosing unhealthy snacking options, thereby increasing the risk for stroke and cardiovascular ailments.
The study, released on September 15 and conducted by researchers from the King’s College London School of Life Course & Population Sciences and ZOE, analyzed the snacking behaviors of 854 individuals who participated in the ZOE PREDICT study.
The research found that nearly half of the study participants failed to align the healthfulness of their meals with that of their snacks, or vice versa. This incongruity had detrimental impacts on health metrics, including blood sugar and lipid levels. Addressing this mismatch could offer a straightforward dietary approach to enhance overall health.
Dr. Sarah Berry of King’s College London and the chief scientist at ZOE remarked, “Given that 95% of the population engages in snacking and that nearly one-fourth of our caloric intake comes from such foods, transitioning from unhealthy options like cookies and crisps to wholesome choices like fruits and nuts can substantially improve one’s health.”

Snacking Patterns and Their Effects in the UK
The study demonstrated that in the UK, snacking constitutes a significant portion of daily caloric intake, with 24% of daily energy derived from snacks such as cereal bars, pastries, and fruits. Among those who snack—which includes 95% of the study cohort—the average daily snack consumption was 2.28 snacks, with 47% consuming two snacks per day and 29% having more than two.
Contrary to widespread perceptions, the study revealed that snacking itself is not inherently unhealthy, provided that the snacks chosen are of high quality. Individuals who consumed healthy snacks like nuts and fruits more frequently were generally more likely to maintain a healthy weight. These high-quality snacks were also associated with improved metabolic health and reduced hunger.
Nevertheless, 26% of the study’s participants reported consuming healthy meals but opting for low-quality snacks. These poor-quality snack choices, characterized by high levels of processing and sugar content, were correlated with negative health indicators and increased feelings of hunger. Such snacks were associated with elevated BMI, increased visceral fat mass, and heightened postprandial triglyceride concentrations, all risk factors for metabolic diseases including stroke, cardiovascular disease, and obesity.
Popular Snack Choices and Their Health Outcomes
The study outlined that the most commonly consumed snacks included cookies, fruits, nuts and seeds, cheese and butter, cakes and pies, and granola or cereal bars. Cakes and pies contributed most to caloric intake (14%), followed by breakfast cereals (13%), frozen dairy desserts like ice cream (12%), donuts and pastries (12%), candy (11%), cookies and brownies (11%), and nuts and seeds (11%).
The timing of snack consumption was also found to be a critical factor in health outcomes. The study showed that snacking after 9 p.m. was linked to unfavorable blood markers in comparison to all other times of the day. Late-night snackers were more inclined to consume foods that are calorie-dense and high in fats and sugars.
Dr. Kate Bermingham from King’s College London and a senior scientist at ZOE commented, “This research augments the existing body of literature indicating that the quality of food is a key determinant in achieving favorable health outcomes. A balanced diet rich in fruits, vegetables, proteins, and legumes is the most effective method for enhancing one’s health.”

Frequently Asked Questions (FAQs) about Unhealthy Snacking and Its Health Implications
What is the main focus of the research published in the European Journal of Nutrition?
The research aims to investigate how the quality and timing of snacks can offset the health benefits of eating nutritious main meals. The study was conducted by researchers from the King’s College London School of Life Course & Population Sciences and ZOE, and it analyzed the snacking behaviors of 854 individuals.
How significant is snacking in daily caloric intake according to the study?
The study reveals that in the United Kingdom, approximately 24% of daily caloric intake comes from snacks. Among the cohort that participated in the study, 95% engaged in snacking, with an average daily snack consumption of 2.28 snacks per person.
Is snacking inherently unhealthy?
No, the study shows that snacking itself is not inherently unhealthy. The quality of the snacks consumed plays a critical role. People who consumed high-quality snacks like nuts and fruits frequently were generally more likely to maintain a healthy weight and showed improved metabolic health.
What percentage of individuals negate the benefits of healthy meals through poor snacking choices?
Approximately 25% of people undo the health benefits of their nutritious main courses by opting for unhealthy snacks. This increases the risk for stroke and cardiovascular diseases.
What types of snacks are most commonly consumed?
The most popular snacks consumed were cookies, fruits, nuts and seeds, cheese and butter, cakes and pies, and granola or cereal bars. Among these, cakes and pies contributed the most to caloric intake at 14%.
What are the health risks associated with poor-quality snacks?
Poor-quality snacks, characterized by high levels of sugar and processing, were correlated with negative health indicators like elevated BMI, increased visceral fat mass, and heightened postprandial triglyceride concentrations. These are risk factors for metabolic diseases including stroke, cardiovascular disease, and obesity.
What is the impact of snacking after 9 p.m.?
The study shows that snacking after 9 p.m. has a negative impact on health, as it was linked to unfavorable blood markers. Late-night snackers were more inclined to consume calorie-dense foods that are high in fats and sugars.
What does Dr. Sarah Berry suggest as a simple way to improve health in relation to snacking?
Dr. Sarah Berry suggests that transitioning from unhealthy snack options like cookies and crisps to healthier choices like fruits and nuts can be a straightforward and effective way to improve overall health.
What are the recommendations for maintaining a balanced diet?
According to Dr. Kate Bermingham, a balanced diet rich in fruits, vegetables, proteins, and legumes is the most effective method for enhancing one’s health. This aligns with the study’s findings that the quality of food is a key determinant in achieving favorable health outcomes.

that’s why i stick to fruits and nuts for snacking. Good to know I’m on the right track, even if its past 9 sometimes.
Wow, never knew that snacking could actually undo the benefits of a healthy meal. Kinda makes you think twice about reaching for those chips late at night, huh?
After reading this I’m definitely rethinking my late-night snacking habits. Those post-9 p.m. snacks might be doing more harm than I thought.
25% of people messing up their health with bad snacks? Thats alarming. Public health needs to step in and do something, like now!
interesting to see how the UK stacks up in terms of snacking. I wonder how it compares to the US. Also, is snacking after 9pm a universal thing or just a UK issue?
I’ve always said quality matters, not just in meals but also in the snacks. Good to see some research backing it up, finally! But what about kids, they snack a lot too?
Timing is crucial, huh. Gotta rethink my late-night munchies I guess. And 2.28 snacks a day on average? Didn’t see that comin.
Swapping cookies for fruit sounds easy but its harder than you think, trust me. Takes a lot of willpower.
