Many people pursue weight loss for better health, but recent research indicates it may not always deliver those benefits. Scientists have found that shedding pounds can release harmful persistent organic pollutants (POPs) into the bloodstream, potentially endangering health.
What are POPs?
POPs are synthetic chemicals that enter the body primarily through the food chain. They originate from industrial processes, such as pesticide production. Once inside, POPs accumulate in fatty tissue, where they remain largely harmless based on current knowledge.
However, weight loss changes this dynamic. As fat tissue breaks down, POPs are mobilized and build up in the blood. Korean researcher Duk-Hee Lee studied 1,100 adults with significant weight changes over the past decade, measuring their blood POP levels. Those who lost 10 pounds or more showed elevated POP concentrations, while those who gained 10 pounds or more had the lowest levels.
What are the consequences and risks?
The exact POP threshold for health risks remains unclear. Overweight individuals should not delay weight loss efforts. Further research on POPs and associated risks is essential to fully understand any potential dangers.
