Processed food and inflammation


Today, processed foods, including fast food, has been easily integrated as a part of mainstream culture. Although they are cheap, quick, and affordable meals, the nutritional content reveals that it is not healthy. A fast food meal comprises of high amounts of calories, fat including saturated and trans-fats, refined sugar, and sodium (8). Diets like these can increase the likelihood of obesity, metabolic syndrome, and cardiovascular disease (5). Inflammation is an important process of the body where healing occurs and protecting against viruses and bacteria (4). Acute or chronic inflammation can lead to a weaker immune system and therefore be more susceptible to infections.

Evidence has shown that refined sugars can increase the release of inflammatory cytokine markers, which are important cell signing proteins in response to inflammation (1, 6). The white blood cells, involved in immune function, are decreased as a result of refined sugars (6). Processed foods with a high glycemic load boost inflammation (2). Aside from sugars, high sodium intake can also increase inflammation by releasing pro-inflammatory cytokines (5). Results of other studies show that saturated fats prompt inflammation of fat tissue (1). Especially in women, trans-fats are indicators of systemic or chronic inflammation (6).

Supersize Me, a popular documentary, followed a man who consumed only McDonald’s meals for thirty days (3). It revealed what fast food could do to the body such as gaining body weight, enduring depression, energy loss, and heart irregularity.

Although it is acceptable to enjoy processed foods from time to time, those should we wary on what damages and negative effects these types of foods can impact the body.
