Exploring the Feasibility of Reducing the Consumption of Food Additives in the Diet of Adults with Obesity
Currently, Canada has over a 29% prevalence rate of obesity, which is defined by a body mass index (BMI) of 30 kg/m2 and above. The prevalence of obesity has been steadily increasing since the 1970s where the prevalence rate was less than 10%. A major obstacle in tackling this health issue is the complexity of its causes. However, it is well known that diet is a major contributing cause.
The role of food additives in promoting obesity is largely unknown. This five-month study explores the feasibility of reducing the consumption of food additives in the diet of obese adults. Eligible participants between the ages of 20 and 80 with a BMI of 30 and above were taught how to limit the exposure to the studied food additives in their diet. At 2 months of follow-up, interviews were conducted to explore participants’ perceptions on the dietary intervention and study conduction. Qualitative content analysis was used to analyze interview data. Overall, the results of this feasibility study will guide the design of future randomized controlled trials that will evaluate the impact of various food additives on body weight.
