There are some evidence that suggest that consuming pesticides containing glyphosate can negatively affect sleep.
Round-Up is one such pesticide whose active ingredient is glyphosate. RoundUp is sprayed on many crops such as wheat, barley, lentils, rice, potatoes, sweet potatoes, citrus, etc. It is not just used as a pesticide, but also as a ripening agent. [reference]
While the main cause of glyphosate is digestive issue, there may be a secondary effect on sleep. Because glyphosate impairs tryptophan synthesis in plants and in gut bacteria. We humans get our tryptophan from foods (including plants, which are now deficient in them), and our gut bacteria produces tryptophan. [reference]
So eating glyphosate laden plants might make us tryptophan deficient. Trytophan is a precursor to making serotonin, which in turn is a precursor to melatonin. Conceivably deficiency in trytophan may cause a deficiency in serotonin, which negatively affects our moods. And a deficiency in serotonin may cause a deficiency in melatonin, which is our sleep hormone.
See reference article that says…
“The amino acid tryptophan is needed to produce serotonin in the brain… It has been shown in human clinical studies that low levels of tryptophan contribute to insomnia”
Our body’s can not make trytophan; we have to eat them in our foods. But if our foods are deficient, then it is pretty difficult to come by. Tryptophan is one of the least plentiful of all the amnio acids.
Just Eat Organic
While we don’t know exactly how significant this effect of pesticide is on sleep, perhaps the effect is small.
But nevertheless, for this and many other reasons, the best recommendation is consume organic fruit and vegetables and meat. By definition, organic includes pesticide free. While meats are not sprayed pesticide, the non-organically raised animals do often eat crops that are sprayed Roundup and some believe that its effects can get into the meat of the animal.
I personally try to get organic whenever reasonably possible to do so.
