[@pjayadeep]

Science can change with more evidence and typically the downsides of any human created interventions are opaque at the beginning and the producers fight to the last to keep their money making product up and running with a good number of consumers locked into their product. So it is good to be suspicious where there's a question about a product especially a chemical that can kill living organisms

So balanced and with an admonition to not fall into a trap of fear.

[@RamaChandran-p7m]

You are right on the matter here, Dr. Gill. I am a retired PhD material scientist who has worked in diverse specialty products industries for over 45 years. I have dealt with numerous cases of materials commonly used in households and industrial environments that are "potential carcinogens or mutagens" but are indispensable for quality of living. In all cases, it is about being aware and taking adequate precautions while using them or being around them. Even today, we use household cleaners with ammonia, organic solvents, etc., which can impact personal health if not used under proper PPE.

I really appreciate this one. I had a vague memory of some people having won lawsuits based on getting cancer from glyphosate, and also had the idea that eating vegetables was almost certainly more positive than whatever the negative of glyphosate was. It was great to learn the state of the science on the matter.

[@waterbug1135]

I'm a long time gardener, grew up on a farm. Glyphosate was considered safe, was widely used so seemed being safe was probably correct. BUT... I never had a reason to take a risk. Plus I had to buy it, store it and the plants died over several days so you had a brown weed instead of green weed. Still had to remove the dead weed. Seemed easier to me to just remove the green weed. Learned to use a knife to push into the ground at the stem which loosens the soils and weed pulls out with roots.

[@michaelmore]

I really appreciate you going over different study types and emphasizing how essential observational studies are, and specifically explaining the differences between case-control and cohort studies.

I farmed and used Roundup for weed control, ended up with Follicular type NHL. Can’t be sure the chemical contributed to it, but the treatment of RCHOP (17 yrs ago) and a change in diet and lifestyle was successful.

[@pedtrog6443]

Glyphosate is a classed as a herbicide, not a pesticide. It's widespread use is generally an evonomic expediency in farming operations rather than a necessity. I would be more concerned about it's effect on invertebrate populations and biodiversity

[@yangtse55]

Esp in conjunction with RUR seeds it minimises tillage among other things.

[@prieten49]

The IARC categorizing Glyphosate as a Class 2A "Probably causes cancer" agent (red meat, working as a hairdreser, night shift work, hot beverages are in the same class) was very controversial. The IARC Working Group that made the finding cherry-picked mostly weak studies and used questionable "invited specialists," one of whom immediately signed a contract as a consultant to lawyers suing Monsanto. The IARC finding has to be considered an outlier when compared to the numerous other regulatory agency findings that Glyphosate is safe.

[@jameschristiansson3137]

Being safe is why it needed to be demonized by assorted miscreants.

[@amarug]

Thank you for this video, very well presented. My take-away here is: even if there are some traces of evidence that show possible links between extreme exposure and some type of cancer, I think I will have to just stash this away into the "not a priority" drawer. In the whole universe of things to focus on that improve your health, this is simply not a priority. What I mean is that focus on the "heavy hitters" that actually have massive proven impact on your overall health. For example, on average, the gained health from like only one hour of good exercise probably offsets three lifetimes of munching on glyphosate.

[@Celticspy911]

Probably is not scientific.

[@JamesTheAxeThrower]

you should do a video comparing “safety thresholds” for various things in America vs Europe. Would be interesting to show the contrast.

[@babybalrog]

[@gabzsy4924]

My main issue with this kind of approach when analyzing the dangers of a substance or nutrient, is that generally speaking, we always do it looking at the worst possible outcome, in this case cancer. What if it causes chronic headaches? What if it causes severe bowl disease? Cancer is awful and deadly, but there’s many other ways to ruin someone’s health other than cancer.

[@gina116]

Glyphosate breaks down relatively quickly, it does not linger in the plant or soil. Unlike pfas, plastics, etc. There are a lot worse toxins out there, that do NOT ever break down!

[@NutritionMadeSimple]

We´ll go over other glyphosate Qs in the future. We have to tackle one a time in order to go over the evidence otherwise it's a 6h video :) and cancer is the one we get the most

[@StingyGeek]

Thanks for taking the time to explore this issue.

[@AlexanderBrands-q3r]

Some context about the IARC: They have evaluated over 1000 substances. Gues how many they have put in group 4, which is "Probably not carcinogenic"? Zero. There used to be one, but they reclassified it. The closest they get is to put something in Group 3, which is "nonclassifiable". Good point about evaluating hazard vs risk. As an example, a 3 inch deep puddle is a drowning hazard because you could pass out and land face first in it, even though the risk of that is exceedingly low.

[@BarryPiper]

The thing that cinched it for me was the Agricultural Health Study that followed almost 90 thousand farmers. They have occupational exposure, so if anyone were going to get cancer from glyphosate, it would be them. This is the seventeen-year study you mentioned. GLY has been in use for half a century. If it causes cancer, where are all those cancers? It's the same argument I have with people who claim that cell phones cause brain tumors. Cell phones have been in use for 30 years. Where are all these brain tumors that cell phones are supposed to be causing? If you're going to claim that chemical X causes illness Y, then we should be able to see a lot of illness Y when we look at a population that has been using chemical X for 50 years.

[@simonbrown8509]

It's because grain with a high moisture content gets a low price. Drying wet grain out is extremely costly, hence the use of glyphosate as a dessicant a couple of weeks before the intended harvest if the grain is heading to getting a low price because of a high moisture content.

I have an uncle who was an oncologist (retired now). He think there is definitely a link but mainly with farmers because they are exposed to glyphosate much more frequently. The casual homeowner probably has little to worry about. Like smoking 1 cigarette per week.

[@Dandelion-32]

Glyphosate has one more use. It is for wilting by spraying the crops around two weeks before harvesting. For wilting, dosages of 50-200% above weed control are used.

[@eliasednie]

This is comparatively rare & only on already matured crops which wouldn't be up taking much into the already matured seeds. The harvest is then processed to remove any outer coverings like seed husk, glume, etc so residue levels on processed grain are miniscule.

[@Shiny54]

This process is called dessicating, and only used in some countries.

[@desireemou2329]

I'm so glad to see this. Thank you for taking on this topic, Gil. It's hard to get a sense of whether to be concerned about glyphosate or just dismiss it, and (to me) you're saying you're not hearing alarms, but you're keeping it on your radar. I'll do the same. You mentioned in the video 'other pesticides' (than glyphosate) and I'd love more on this. We are told by some to eat only organic because otherwise it's dangerous to our health, yet people like Dr Andrea Love, who you link to as providing a different point of view than yours, is one of the people saying conventionally-grown produce is better and, essentially, safer than conventional. After reading and listening to a number of her posts, I was starting to wonder if organic produce was regulated at all, and whether the ("legacy" I think they call them) pesticides they use in organic farming (the one that's almost always brought up is copper sulphate, which seems to be used on blueberries and maybe grapes, but not sure what else?) are in fact far more dangerous than pesticides like glyphosate, partly because it/they apparently need/s to be used in higher doses to be similarly effective, but partly because they bioaccumulate faster/more insidiously than newer pesticides like glyphosate (it's unclear if that's in humans or in the environment, though neither is great). What threw me off, though, was her certainty. Is it really that straightforward that organic is just a gimmick? I would love if you were able to lay out what's been studied about organic pesticides. I also want to say I appreciate your approach, and how you present the findings. It must take a lot of effort and time.

Do you ever take into account who paid for these studies? May be my personal skepticism in play, but it would be worth looking into.

[@NutritionMadeSimple]

We note funding source as we're going through but the truth is when you look at a topic systematically (as opposed to an isolated publication), funding rarely makes a big difference (because you're looking for a consistency of findings across different publications/teams etc). In this case for example the cohort studies that were the main source of our concern were not industry-funded. A few narrative reviews funded by Monsanto took a more optimistic view but those have low weight anyway

[@williamverhoef4349]

The connection between different studies and different blood cancers is odd but should not raise our index of suspicion. Every cancer is essentially a different disease. Also, if there IS an effect it is marginal, and we are talking only about those who use the chemical on farm crops. The IARC measures hazard, not risk. So, the act of "drinking water" is mortality HAZARD from the point of view that, if you drink 5 litres quickly it will kill you but the RISK of "drinking water" is negligible. Bottom line: Perhaps at most a marginal risk to those who use large doses such as farmers, but no risk from residues on food - which should be washed in any case - no risk from using the chemical on weeds around the home - but wear long pants don't use in windy conditios - but all the alternatives are all demonstrably worse.

[@rosemary20001]

[@amandamessbarger]

I assume most agricultural workers are relatively young and healthy. If you look at young people who smoke and then scope out 5 or 10 years, you'll probably find little to no lung cancer. I think some of these cancers are very slow growing. This is how the tobacco industry was able to muddle the evidence for so many decades. I don't know if that factor was controlled for in these studies with glyphosate or if it's even possible.

Finally, not a emotional reaction, but actually looking at what it does in REALITY. We (master gardeners in my state) went over and over the possible toxicity. To sum it up, our director, who was pro organic gardening, felt glyphosate was even safer than broad-leafed herbacides, broke down faster, etc. She recommended it, but only when used as directed. The compounds do not linger in the environment. Breaks down into inert compounds. Unlike plastic! Plastic is persistent in the environment and everyone is still using that everywhere!

Another interesting question/point that I have heard raised in concern of Glyphosate exposure is that more and more weeds are becoming resistant to it.

[@simonbrown8509]

Glyphosate is routinely used as a dessicant a couple of weeks before harvest to ensure harvested wheat is dry and so gets a good price. I recommend the Harry's Farm channel for understanding actual uk practice. My concern is over the presupposition that cancer is the problem. What if it acts as an accelerant on the current epidemic of metabolic problems. ?

[@ybkishoreVid]

Thank you for this unbiased look at glyphosate. While I'm not an expert, I wanted to bring a few points to your attention. There are other very common crops sprayed with glyphosate besides the GMO versions you mention in the video. This is generally done just before harvest so the crops are killed and dried out for easier machine harvesting. Wheat is very commonly sprayed with glyphosate, to my understanding. I'm not sure if they do this with rice. Also, this process may vary across the globe. Another point, which you already touched on, is that exposure during spraying may have a very different effect than ingestion. I think it would be helpful to investigate whether ingestion disrupts the microbiome and how that leads to health issues. It would be good to see/summarize studies on the effect of glyphosate on microbiome changes and their health effects. We've heard a lot about how a diverse/strong microbiome is very important for good health.

Imagine Round Up soaking into the plant and it's never rinsed off. It just goes straight into bread or oats and from there harvested quickly and thence directly into your body.

Eg, pyrethrins (naturally occurring compounds) might be allowed in organic farming but not pyrethroids (synthetic) insecticides, yet neither are safe to breath in over extended periods (possible increased Parkinson's Disease risk). Or neem, etc. Plus sometimes the additives (not main active compounds) to pesticide sprays have significant deleterious environmental impacts, eg wetting agents - surfactants (detergents).

[@kazoz3520]

I'd love to find out the actual data as to how many farmers actually use herbicides on wheat & oats on harvest. Wheat is grown in drier (& more marginal) climatic cropping areas (sometimes irrigated - ie lack of water more an issue, not wet harvest) & is of lesser value than corn & beans. It's very expensive to use herbicides. I don't see the (long term) value in it. But then, I'm in Australia.

In my country , the Netherlands, glyfosate is not so much linked to cancer, but more to Parkinson’s, according to some of the most well known neurologists in our country. Neurologist Bas Bloem thinks there is a chance for Parkinson’s to become epidemic because of pesticides.

[@mynameisnobody7997]

Gil, are you aware Monstanto/Bayer has had to pay billions in lawsuits related to glyphosate harming people?

[@NutritionMadeSimple]

yes but conclusions on health effects have to be based on the scientific evidence. If any scientific documents were made available in those proceedings that are not published, then that could be relevant. The verdict itself tells me very little, it involves jury deliberations and other factors that are separate from scientific evidence

[@mynameisnobody7997]

@@NutritionMadeSimple Wouldn't lawsuits, where billions are at stake, scrutinize the scientific evidence as rigorously as is humanly possible? And thus the findings must be examined. Please review the "Monsanto Papers".

[@NutritionMadeSimple]

@ not necessarily rigorously, the defendant will try to argue their product is safe by whatever means possible and the prosecutor will try to argue harm. Neither is necessarily looking for "truth" here. I´m open to any info coming from it, I´m just putting it in perspective that it's a very different process from scientific data

[@BH-obh]

Thanks. I'm still troubled by the fact that glyphosate crosses the blood-brain barrier, one of its byproducts aminomethylphosphonic acid accumulates in the brain and causes dementia in rodents. Its use may be responsible for the upswing in neurodegenerative diseases...Parkinson's, Alzheimer's etc., that take many years to manifest themselves, beyond the timeline of RTC's.

[@samuelbonacorsi2048]

As a farmer, it’s difficult to zero in on a particular chemical because we are exposed to many chemicals, solvents and fuels. It seems prudent to discontinue glyphosate as a crop desiccant in grain crops. Farmers use to use Paraquat but it seems like the switch to glyphosate was a move in the right direction.

[@Annzy99]

What about the glyphosate entering the water table that is consumed by the neighboring population?

[@AGAU1022]

Yeah there isn't much we can do about this since in Y Zhang et al, canola oil and corn were associated (if anything) a lower rates of cancer mortality than olive oil. (Cooking oil/fat consumption and deaths from cardiometabolic diseases and other causes, 2021)

[@maryhandlename]

Thank you! What about glyphosate and neurological conditions, particularly Parkinson's? I know, at least in the US, Parkinson's is more prevalent in the rural areas.

[@cathylewis2181]

I have been a subscriber for a long time and almost always love your content. But the one thing I don't really understand is why you don't more readily recommend organic produce where it's available. Here where I live it's almost the same price as non-organic. And I know organic doesn't mean it's free of all chemicals but it's definitely better. Similarly, why not recommend non-GMO where it's available because then there is a much better chance they're not using roundup. I do believe Roundup is used on more grain products than you listed as well. Thanks for being a calm and studied voice in a sea of screamers. PS I like your Brazilian outro music.

[@NutritionMadeSimple]

hi, we don't really issue recommendations per se, we mostly go over the available evidence on different topics so people can make informed choices. When we reviewed the data we did not find consistent evidence of superiority of organic or non-GMO, so it's a personal choice. We're planning an updated review at some point

[@lorrifreitas4344]

@@NutritionMadeSimple I would be very much interested in a new analysis, one that would include differences in soil health, invertebrate biodiversity/health, and impact on agricultural workers, not just consumer health.

This is why you homegrow! even the places that claim to not use it use different versions of similar chemicals that aren’t officially recognized in America yet so they can use it and claim they aren’t since it doesn’t show up on the tests.

Why it ks more painful then spraying other herbs/plants?

[@virginiemazy7054]

Q for Gill. What do you mean with organic having its own pesticides ? I thought orgamic meant no pesticides or almost none ? Could you elaborate on that ? And maybe make a video on the topic : is it better to eat organic or not ?

its so safe that the person spraying it on plants is covered head to toe in personal protective gear. whats he afraid of?

I wouldn't swim in vinegar but have no problem eating pickles. Poison is dose dependent. Ironically, vinegar is actually much more toxic than glyphosate in animal studies.

[@StuartS-qe7yp]

Like I figure, glyphosate is relatively save, but with everything use precautions when using glyphosate.

[@bluebadger3223]

I'm a little uncomfortable with Gil's statement that he "hopes it doesn't cause cancer". There's a lot of money involved in the question of Glyphosate and cancer. I would question who did the Cohort studies and whether they have a hidden vested interest. He completely dismissed the case studies. Another thing I have a problem with is Gil's rarely deviating from the consensus view and his eagerness to attack social media like that's his mission.

[@NutritionMadeSimple]

Hi, the cohorts had no industry funding, are not particularly reassuring for the glyphosate industry (given the signal of different blood cancers) and underlie our disagreement with almost every major health organization in the world stated in the video. We hope future evidence proves us wrong and shows no increase in cancer (surely no one hopes for more cancer). Thanks.

[@robinpetersson3081]

Roundup was banned in Europe until they deemed it safe to use. Another clue that Glyphosates are probably mostly safe.

[@pynn1000]

EU is monitoring use, health etc. I'm in an area in EU where glyphosates were heavily used, been reduced. (No people in hazard suits spraying sidewalks, man stopped spraying in field near my house when I walked on a path through it a few months ago.) Like cars getting "safer"?
