Yes, corn can cause health problems, particularly when it's highly processed.
According to Neil Iyengar, an oncologist at Memorial Sloan Kettering Cancer Center, a significant concern with corn lies in its transformation into inflammatory and metabolically unsafe substances through processing. This processed corn can contribute to various health issues.
Here's a more detailed breakdown:
-
Processed Corn Products: Many common foods contain highly processed corn derivatives, such as:
- High-fructose corn syrup (HFCS): A sweetener linked to obesity, type 2 diabetes, and metabolic syndrome.
- Corn oil: Often high in omega-6 fatty acids, which can contribute to inflammation when consumed in excess compared to omega-3s.
- Corn starch: Used as a thickener and filler in numerous processed foods, contributing to refined carbohydrate intake.
-
Inflammation: Processed corn products can promote inflammation in the body. Chronic inflammation is linked to various diseases, including heart disease, arthritis, and even cancer.
-
Metabolic Issues: The high sugar content and rapid absorption of some processed corn products can lead to insulin resistance and other metabolic problems.
-
GMO Corn Concerns: While not directly addressed in the provided reference, it's worth noting that much of the corn grown in the United States is genetically modified (GMO). Some individuals have concerns about the potential long-term health effects of consuming GMO foods, though scientific consensus generally supports their safety.
-
Mycotoxins: Corn can be susceptible to contamination by mycotoxins, toxic substances produced by molds. These mycotoxins can pose health risks if consumed in significant quantities.
In summary, while corn itself is not inherently unhealthy, the form in which it is typically consumed – as highly processed ingredients – can contribute to inflammation, metabolic problems, and other adverse health outcomes. Choosing whole, unprocessed corn, like corn on the cob, can be a healthier option.
