What’s in Those Plastics?
Phthalates levels in teen urine linked to higher insulin resistance
(dailyRx News) It can often take a while for researchers to learn more about the effects of different substances in the environment on our bodies. Phthalates are one of those substances we’re learning more about.

A recent study found that teens with high levels of phthalates in their urine were also more likely to be insulin resistant.

Phthalates are compounds added to plastics to increase their flexibility and durability. For example, they are often added to PVC to soften it.

Insulin resistance can be a risk factor or a sign of type 2 diabetes.

This study did not show that phthalates cause insulin resistance or similar problems. More work is needed to understand the relationship between phthalates and insulin resistance.
“Look for phthalate-free products.”

This study, led by Leonardo Trasande, MD, of the Department of Pediatrics at New York University’s School of Medicine, looked at whether insulin resistance was linked to teens’ exposure to phthalates.

Insulin resistance means the body’s cells do not properly respond to the hormone insulin, which is used to process sugars in the body. Increased insulin resistance can increase the risk of type 2 diabetes.

A wide range of products may contain phthalates, including household goods, electronics, toys, medical devices, personal care products, textiles and pharmaceuticals.

Concerns about the safety of phthalates have been increasing, but there is still more research needed to understand their possible effects on the body. (Read more)
