Chemicals versus Calories
Obesity has become an epidemic in our country. According to the CDC, in 2015 and 2016, 93.3 million adults and 13.7 million children were considered obese. For adults, that is approximately 40% of the population. In addition to decreased energy and muscle mass, obesity leads to other preventable conditions such as Type II Diabetes, heart disease, and stroke. All of which have a heavy burden on a person’s overall health, as well the healthcare system as a whole.
Many studies have been conducted to determine the main cause of obesity. Body mass index (BMI) is a key characteristic studied in many experiments. BMI is determined by comparing a person’s height to their weight and can be a strong predictor of health outcomes. Yang (2010) discusses a study that compares BMI, gender, ethnicity, and diet which found those who chose to drink beverages containing artificial sweeteners had consistently higher body mass index than those who did not. In an attempt to create “healthier” options, artificial sweeteners are added to beverages to create total overall calories. However, while these drinks may have lower calories, the artificial sweeteners used actually trigger pathways in the brain that make the body crave more sugar. In fact, artificial sweeteners increase appetite and motivation for food and trigger the same reward pathways within the brain as sex and drugs (Yang, 2010). Further, artificial sweeteners encourage increased sugar consumption, and thus an overall increase in calories (Yang, 2010). Whether artificial sweeteners or actual sugar cane, if consuming sugar can trigger our bodies to crave more sugar, this creates a cycle of increased energy consumption which leads to weight gain. This increase in weight is directly linked to other comorbidities such as heart disease and stroke, as mentioned above.
Artificial sweeteners are prevalent in many of the commonly consumed beverages in this country. Examples of these include aspartame and saccharin. It is important to read labels and choose to buy real foods to limit our body’s exposure to these chemicals. Further, choosing whole foods, such as whole grains, fruits, and vegetables, can help our bodies regulate sugar levels more effectively, which will reduce our cravings and help our bodies maintain a healthier weight overall.
