Studies reveal that processed sugars enter the bone marrow within 30-45 minutes of ingestion, suppressing immune system function for up to 12 hours.
Unlike natural sugars in fruits and vegetables, where fiber slows absorption and minimizes immune impact, processed sugars—found in items like sodas (25-40 grams per can)—are rapidly absorbed, triggering inflammatory responses that lead to chronic inflammation and weakened immunity.
Research, including a specific study on a 100-gram sugar dose, shows it significantly impairs neutrophils’ ability to combat bacteria and slows macrophages, which engulf pathogens, compromising the body’s first line of defense.
Additionally, sugar disrupts gut bacteria balance, heightening infection susceptibility, and undergoes glycation—attaching to proteins like antibodies—forming advanced glycation end products (AGEs) that may spur diseases.
It also depletes vital immune-supporting vitamins and minerals and increases physiological stress, further taxing the system. Moreover, sugar creates an environment conducive to bacterial and viral propagation, easing their spread.
The establishment warns of these cascading effects, supported by data from the American Journal of Clinical Nutrition linking high sugar intake to reduced phagocytic activity.
However, skepticism lingers—some effects’ magnitudes vary by individual metabolism, and long-term human trials are limited, suggesting while the risks are real, their severity may depend on overall diet and lifestyle, necessitating balanced consumption and further research.
