The Evolving Consensus on Diet and Health: A Focus on Unhealthy Food Consumption

While the definition of 'health' remains a subject of ongoing debate in academic literature, with diverse perspectives such as 'the ability to adapt and self-manage' proposed (Huber et al., 2011), a compelling consensus is emerging regarding the constituents of an unhealthy dietary pattern. Research findings consistently point to a whole-food plant-based diet as the most beneficial approach for maintaining optimal health (Orlich et al., 2014). Such diets emphasize unprocessed and minimally refined foods, predominantly comprising fruits, vegetables, legumes, nuts, and whole grains. In contrast, an unhealthy dietary pattern is characterized by a preponderance of processed foods (e.g., fast food), saturated fats (e.g., red meat), salt (e.g., processed meats), and refined sugars (e.g., fizzy drinks) (Orlich et al., 2014; Schatzkin et al. 2003; Greger & Stone, 2016). While the precise biological mechanisms underlying the health benefits of vegetables compared to deep-fried foods are complex and multifaceted, the deleterious effects of unhealthy foods on overall health are well-established. These detrimental dietary patterns and food choices are strongly implicated in the development of chronic diseases through their contributions to oxidative stress and inflammation (Greger, 2019).
