Reason why I now grow my own wheat and all other staple food.
The chart below is from a December 2013 study published in the Journal Interdisciplinary Toxicology examining glyphosate pathways to modern diseases such as celiac and gluten intolerance. [1][2]
Using Roundup on wheat crops throughout the entire growing season and even as a desiccant just prior to harvest may save the farmer money and increase profits, but it is devastating to the health of the consumer who ultimately consumes the glyphosate residue laden wheat kernels.
Pesticides and herbicides are making their ways to our dinner tables since 1980s. Just because Roundup doesn’t kill you immediately doesn’t make it nontoxic. In fact, the active ingredient in Roundup lethally disrupts the all important shikimate pathway found in beneficial gut microbes which is responsible for synthesis of critical amino acids. After 30 years, effectsare on surface. We are now in the dark zone. What follows from here is painful.
And this is not just wheat story. Same model is now replicated in other crops too. 
🙁
Better we inspire our farmer brothers to get rid of such moron farming and bring mother (Gau mata) home back. They may experience reduction in profit but nothing better than disengaging from horrible karma of serving poison to all consumers 🙁.
It is not mere coincidence that Punjab is having highest number of cancer cases post green revolution euphoria. Karma. 🙁

The Real Reason Wheat is Toxic (it’s not the gluten)
[2] http://www.thehealthyhomeeconomist.com/real-reason-for-toxic-wheat-its-not-gluten/
We need to differentiate between toxicity and allergy. The herbicides and insecticides are known toxins and cause toxicity depending on the dose or quantity consumed. Gluten is not toxic by itself but more cases of celiac disease are being reported. There is no study to show that wheat grown on cowdung does not cause the allergy. To feed people we need more land, more water and more inputs. Simply going back to cowdung alone will take us back to 1950s or 60s when many parts of the world suffered from food shortage.
Use of insecticides can be reduced through GM technologies as seen in only one third use of insecticides in case of BT cotton as compared to non-BT for the control of ball worm. However, GM technology is also not acceptable to many. We have to also see the livelihood security of marginal farmers as they do not have the loss bearing capacity due to limited resources and low investment. The bigger question is how can we ensure better livelihood to a family that ows only 0.5 to one hectare of land as the sole source of income. How to create alternate jobs, skill the villagers and help raise their living standards.
