A quarter of people are undoing the benefits of healthy meals with unhealthy snacks, which increases the risk of strokes and cardiovascular disease. The findings, published in the European Journal of Nutrition by researchers from the School of Life Course & Population Sciences and ZOE, details the snacking habits of 854 people from the ZOE PREDICT study.
Researchers found that half of the participants do not match the healthiness of their meals to their snacks and vice versa. This difference has a negative effect on health measures, such as blood sugar and fat levels, and addressing this could be a simple diet strategy to improve health.
Contrary to popular belief, the analysis showed that snacking is not unhealthy - as long as the snacks were healthy. People who ate high-quality snacks like nuts and fresh fruits frequently were more likely to have a healthy weight compared to those who don’t snack at all or those who snack on unhealthy foods. Analysis also showed good quality snacks can also result in better metabolic health and decreased hunger.
However, a quarter (26%) of the participants reported eating healthy main meals and poor-quality snacks. Poor-quality snacks, such as highly processed food and sugary treats, were associated with poorer health markers and left people feeling hungry. Unhealthy snacks were linked with higher BMI, higher visceral fat mass and higher postprandial – the period after eating a meal – triglycerides concentrations, all of which are associated with metabolic disease such as stroke, cardiovascular disease and obesity.
