The document discusses how sugar and insulin levels in the body are regulated, and how certain compounds can disrupt this balance. It explains that the pancreas produces insulin to regulate blood sugar levels, and that while glucose normally stimulates insulin production, studies show that fructose and bisphenol A (BPA) can also cause the pancreas to release insulin. One study found that when fructose and glucose appear together, more insulin is produced than with glucose alone. A separate study found that even small amounts of BPA, a common pollutant, can trigger unnecessary insulin production, potentially leading to insulin resistance and an increased risk of type 2 diabetes over time.
