High consumption of common chemical preservatives increases the rate of type 2 diabetes by 47 percent, according to two large-scale studies published in Nature Communications and BMJ, shorouknews.com reported on Saturday.
Researchers analyzed health and dietary data for more than 100,000 people over 14 years from 2009 to 2023. The team examined 17 common preservatives used in prepared and canned foods to extend shelf life.
Out of the 17 compounds studied individually, 12 showed a direct link between higher consumption and increased disease risk. These chemical compounds interfere with immune pathways and trigger chronic inflammation in the body, setting the stage for the condition.
Cambridge data tracks 57 chronic conditions
Patients diagnosed with this type of diabetes face exposure to 57 other chronic health conditions compared to people without the disease.
Affected individuals experience these secondary health problems an average of five full years earlier than healthy peers. The risks multiply sharply for anyone diagnosed before turning 50 years old.
Renal failure risk in its final stages climbs by 5.2 times among patients. Various forms of cancer, including liver and breast tumors, show an overall 9 percent increase, while liver cancer alone jumps by 4.4 times.
Neurological and eye complications multiply from diabetes
Neurological problems double by 2.6 times among diagnosed individuals. Eye disorders, including macular degeneration, increase by 3.2 times, alongside notable negative impacts on mental health, the digestive tract, and the circulatory system.
Researchers outlined a vicious cycle starting with an unhealthy dietary pattern rich in preservatives. This pattern leads to diabetes and eventually triggers a long, heavy chain of chronic illnesses.
Scientists recommend that manufacturers reevaluate additive usage and cut unnecessary preservatives in ultra-processed foods. They advise consumers to gradually return to fresh, natural foods and reduce reliance on canned and manufactured items to protect long-term public health.
Frequently Asked Questions
