Congratulations on making healthier food choices for your meals. However, have you considered what you snack on throughout the day? A new study suggests that 1 in 4 individuals may be undoing all the benefits of their healthy eating habits by opting for ultraprocessed and sugary snacks.
The senior author of the study, Sarah Berry, a researcher at King's College London, emphasizes the significance of snacking in our daily lives. She highlights that 95% of us snack, and nearly a quarter of our daily calorie intake comes from snacks. Making a simple swap from unhealthy snacks such as cookies, crisps (chips), and cakes to healthier options like fruits and nuts can greatly improve our overall health.
The study, conducted in the United Kingdom, found that over 90% of adults in the United States consume one or more snacks daily. In the UK, 47% of participants reported eating two snacks a day, while 29% snacked even more frequently. Surprisingly, more than a quarter of participants who consumed healthy main meals opted for highly processed and sugary snacks, which can increase feelings of hunger.
Dr. David Katz, a specialist in preventive and lifestyle medicine and nutrition, emphasizes the importance of being proactive in our food choices. Similar to how we protect ourselves from unfavorable weather conditions, we should take measures to protect ourselves from the "climate" of junk food. Katz suggests taking control of our food environment by always having convenient and nutritious options readily available, such as nuts, fresh fruit, dried fruit, and hummus.
The study, published in the European Journal of Nutrition, analyzed the snacking habits of 854 participants in the Zoe Predict study. Results showed that consuming poor snack choices was associated with higher BMI, higher visceral fat mass, and higher postprandial triglyceride concentrations. These markers are typically associated with metabolic diseases like stroke, cardiovascular disease, and obesity.
The timing of snacking also proved to be significant. Snacking after 9 p.m. was linked to consuming calorie-dense foods high in fat and sugar. Participants who snacked later in the day demonstrated worse blood markers that could potentially lead to chronic diseases compared to those who snacked earlier.
However, not all snacking habits are unhealthy. The study found that individuals who frequently consumed high-quality snacks such as nuts and fresh fruit were more likely to maintain a healthy weight compared to non-snackers or those who opted for unhealthy snacks.
To ensure that you make healthier snack choices, Dr. Katz recommends carrying an insulated snack pack filled with nutritious foods you enjoy. This way, you have control over what you eat when you're on the go or at the office.
In conclusion, while it is great to focus on healthier main meals, it is equally important to choose nutritious snacks. By making conscious decisions about what we snack on and when we snack, we can improve our overall health and reduce the risk of chronic diseases.
