A study published in JAMA tracked people over the age of 50
in Southern California from 1993-1996 to 2014-2016. Urine samples were
collected over the time period to measure levels of glyphosate and its
metabolite aminomethylphosphonic acid (AMPA). They found that the
percentage of people who tested positive for glyphosate increased over
500% in that time period. Glyphosate usage also increased by 1208%
during this time period, making it very unlikely that this was just a
coincidence. (https://jamanetwork.com/journals/jama/fullarticle/2658306)
Crops sprayed with glyphosate may surprise you: almonds, avocados, cherries, corn, grapes, grapefruit, peanuts, pecans, rice, soy beans, spinach, sugar beets, walnuts, wheat. (https://www.cornucopia.org/2016/05/widespread-use-glyphosate-food-supply/)
There are no known safe levels of glyphosate a person can eat.
This link also shows what percent of crops are sprayed with glyphosate: https://livelovefruit.com/what-crops-are-sprayed-with-glyphosate/. There are 70 crops here sprayed with glyphosate. Organic crops can also be tainted by overspray from a neighboring field, or from water used by the organic farm that is downstream from a non-organic farm that uses glyphosate.
Here are the results of studies listing which percent of people tested positive for glyphosate in their bodies. (https://www.moyoway.com/europes-top-5-glyphosate-herbicide-toxic-countries.html) Malta (90%), Germany (70%), Great Britain (70%) and Poland (70%) had the most percent of people with glyphosate in their bodies. They don't have to grow crops that are sprayed with glyphosate, crops that are tainted can be imported from other countries.
Animal tests show that up to 30% of glyphosate is absorbed into the body. A week later, there is still about 1% remaining.
