The US uses massive amounts of the pesticide glyphosate (commonly known as Roundup) on farms, the sides of roads, and even by homeowners on their properties. More than 127,000 tons of this weed-killer (herbicide) is used just on US farm fields! But studies, including this recent study, find that glyphosate is also linked to health harms, including lower weights and earlier birth of babies.
The recent research found that increased glyphosate applications on farm fields in the last two decades (especially due to genetically modified crops and preharvest use) has especially impacted pregnancies and babies born in rural areas of the United States. That is, pregnant women in farm areas are the most impacted by glyphosate - it's not just used on the fields nearby (they get exposed from pesticide drift), but also in the non-organic foods that they eat. Lower birthweights are generally considered a predictor of health problems (and higher health care costs).
Evidence for health harms from glyphosate are increasing each year, such as an increased risk of cancer (e.g., non-Hodgkin lymphoma), premature births, endocrine disruption, and even disruptions of the gut microbiome (it kills beneficial microbes in the gut, including such important keystone bacteria as Faecalibacterium prausnitzii.) The percentage of people with glyphosate detected in their urine, and the amount (concentration) has been rising over time. It can now be detected in almost all of us, including children.
By the way, the US allows much higher levels of glyphosate residue on foods than countries in other parts of the world, including Europe. But in Brazil it's even worse with levels much higher than in the US, and with higher rates of childhood cancer and infant mortality.
Organic food production does not allow the use of glyphosate. To lower glyphosate levels in your body - increase the amount of organic foods that you eat.
Excerpts from Science: Common weed killer may be harming infants
Babies in rural counties of the United States that use a common weed killer are born slightly earlier and underweight, a large study finds. These changes, although small on average, could result in learning disabilities and an increased risk of infection, researchers reported last week in the Proceedings of the National Academy of Sciences, resulting in more than $1 billion in health care costs nationwide each year. ...continue reading "Study Finds Common Pesticide Has Effect On Pregnancies and Babies"
