In recent years the trend of following a gluten-free diet for individuals that do not suffer from celiac disease or non-celiac-gluten-sensitivity has grown, with followers claiming a multitude of benefits. Despite the popularity, research into the existing literature related to the topic paints a different picture. Media posted by popular sources as well as peer-reviewed sources claim that adhering to a gluten-free diet without a diagnosis may actually lead to negative side effects such as an increased food cost with lower nutritional content, nutrient deficiencies, and weight gain. Existing literature also suggests that claimed advantages, such as increased athletic performance, may be due to the placebo effect.
