Can glyphosate residues on food contribute to metabolic syndrome?

What's actually in it

Glyphosate is the world's most widely used herbicide, found on wheat, oats, corn, soybeans, and many other crops. It's sprayed both as a weed killer during growth and as a drying agent right before harvest. Residues remain on the food you buy. You eat small amounts daily through bread, cereal, crackers, and other grain-based products.

What the research says

A 2026 scoping review in Environ Res gathered both human studies and lab research on glyphosate and metabolic syndrome. The review found evidence that glyphosate exposure is linked to obesity, high blood sugar, abnormal cholesterol, and high blood pressure, the cluster of problems known as metabolic syndrome.

Glyphosate may cause these effects by disrupting gut bacteria, triggering inflammation, and interfering with hormone signaling. Daily low-level exposure through food may be enough to shift metabolic function over years.

Choose organic grains and cereals when possible, especially oats and wheat products. Wash produce thoroughly. Eating a varied diet helps reduce your total glyphosate load.
