Pesticides in Shanghai and Globally

Pesticides -- Shanghai Problem

Pesticides, herbicides and fungicides are big problems here in Shanghai. Apparently we live in the city with the highest reported field application of pesticides (kilograms per hectare) out of the whole country. According to the report by Zhang et al 'Global pesticide consumption and pollution: with China as a focus' Shanghai applies 12.72 kilograms per hectare of pesticides, which was the heaviest utilization of 32 cities and provinces studied. The lowest utilization rates were in the least industrialized provinces, Inner Mongolia and Tibet (0.15, 0.01 kg/ha respectively).

Pesticides are (Obviously) Toxic and Kill

Pesticides, herbicides and fungicides may not be lethal to large mammalian hosts like humans but the mechanisms in which they wreak chemical havoc to pests, weeds/grasses and fungus/molds can affect us either directly or our gut ecosystem which contains 100 trillion mitochondrial-like creatures (bacteria, mycobacteria, protozoa) and fungi. ~~Half of the deaths that occur worldwide secondary to pesticide exposures are here in China. 'According to a report of WHO and UNEP, worldwide there are more than 26 million human pesticide poisonings with about 220,000 deaths per year (Richter, 2002). In the United States, there are 67 thousands human pesticide poisonings per year. In China, there are 0.5 million human pesticide poisonings with 0.1 million deaths per year. (Zhang et al 2011)'

The mechanisms of toxicity of pesticides, herbicides and fungicides usually target a specific neurochemical or metabolic mechanisms that translate toxicity to the cellular, organ and organismal levels:
--sodium channel disturbances (yes our sodium channels are vital; see prior nephropal Evolutionary Brain)
--glyphosate toxicity (see Dr. Tourgeman's nephropal post: Can Glyphosate Herbicide Formulations Damage Humans?)
--mitochondrial toxicity -- electron transport
--mitochondrial toxicity -- fatty acid metabolism
--mitochondrial toxicity -- respiratory complex
--trace heavy metals -- mercury, asenic, cadmium and lead --which severely depress metabolic enzymes (mitochondrial, thyroid, adrenal, neural, gut i.e. DPP IV, pancreatic/digestive, etc)




Pesticides: Global Problem

Although the knowledge and understanding are incomplete, the data and information on how pesticides, herbicides and fungicides are transported, degraded and distributed into the ecosystem are pretty damning. The toxicity effects may not immediately disable and maim but may be chronically sublethal and epigenetic. Since all life on earth is interconnected, the network of disturbances can be subtle. Damaging effects perhaps act in concert either additively or synergistically with other stressors, gut dysbiotic factors and amplified by our trigger-happy immune systems. Zhang et al say that 99% of pesticides, herbicides and fungicides do not even hit the intended target. 99% of pesticide applications are distributed into the environment and ecosystem by spray drift and surface water runoff. The investigators Zhang et al state 'High-residual pesticides like DDT have been detected in the Greenland ice sheet and the bodies of Antarctic penguins which were resulted from atmospheric circulation, ocean currents and biological enrichment of pesticides.' The early players of the damage and adverse effects are the bees, insectal larvae and algae on land and in related water masses. In the next tier of ecological effects, their predators (insects, fish, sealife) are affected either indirectly by reduction of food availibility or direct biochemical, metabolic, immune, endocrine, sexual and reproductive disruptions.

And... Up and up the PREDATOR ECOSYSTEM CHAIN.

[I doubt humans can claim being apex predators, but perhaps apex pests and homo purgare]



Fish: One of the Most Pesticide-Ridden and Toxic Foods

My family and stopped eliminated 80-90% of our fish and seafood consumption (both farmed and wild) when I was first pregnant 12 years ago. I figured what wasn't safe for my baby and I just was not safe, PERIOD. We try to eat ancestrally but seafood just is not part of the equation at this time. Many cultures who subsist on fish and their marine predators (seal, whale) are documented to have elevated levels of persistent organic pollutants (POPs, pesticides, PCBs, solvents, etc) and heavy metals: Great Lake Anishinaabe, Arctic and Greenland Inuit, natives of the Alaskan Aleutian Islands, Amazon Brazilians, Peruvians, and Faroe Islands inhabitants. Where is the source? Pesticides and industrial pollution are bioaccumulated in algae, daphnia, marine life and large predacious fish and marine mammals. Human variance shows that not everyone is severely affected by heavy metals (mercury) and pesticides but certainly some are more sensitive than others or bioaccumulate at extremely higher rates than other individuals. The carriers of apo E4 allele, the ancestral 'efficiency' allele, appear to exhibit higher harboring and decreased detoxification of trace heavy metals (iron, copper, lead, mercury). This may explain the link between increased incidence of central obesity, metabolic syndrome, T2DM, Alzheimer's and dementia and those of ethnic descent where the apo E4 allele is more dominant (Inuit, Amerindians, aborigine subpopulations, northern Chinese, northern European, Africa).



The Jungle: Food Safety in China

Living in China has many 'challenges' (I could list but that would be a brick of novella) but I would have to say food safety TOPS my MANY MANY MANY lists. On one hand Shanghai is one of the most progressive cities of the world I have been fortunate to visit (Paris, Hamburg, NYC, Chicago, SF, Tokyo, Kyoto, Taipei) yet in the context of food safety and standards of quality, I think it is one of the cities with the least quality control and national oversight. For every daily food safety scandal that hit the media, I always wonder how many dozens didn't hit the media under China's scrupulous censorship. We live here in the times that pre-date Upton Sinclair's 'The Jungle' (free PDF HERE, courtesy of Penn State).

Super wonderful people here in Shanghai have been graciously generous in sharing their food suppliers ('The Avocado Lady'), chains of safe food purveyors and organic grassfed meat and egg sources, CSAs (see picture BIOFarm) and safe homemade goodies. Part of the adventure of expat living has been meeting other like-minded freaks in a foreign country.

Pesticides May Cause U.S.A. Insulin Resistance and Obesity Trends



Emancipator
'Greenland'




Modern Big Tobacco-Agra/Monsatan Crops

Crops are generally coated with pesticides for the last 30-50 years. Are they toxic? Pesticides are upregulated into the food chain via consumption (corn, soy) by feedlot livestock and poultry. Let's not forget tobacco (cigarettes, snuff, cigars, etc). 'Tobacco is a pesticide-intensive crop. With nearly 27 million pounds of pesticides (including insecticides, herbicides, fungicides, and suckercides) applied to the U.S.-grown crop from 1994 to 1998, it ranks SIXTH in terms of the amount of pesticides applied per acre. The tobacco industry regards pesticides as essential to tobacco production, stating that “the crop could not be produced economically without them”.'

Additionally pesticides are employed in municipalities (public schools, parks, government land) and personal home use (termites, ant control, weeds control, lawns, etc). Although pesticides do not taste, smell or look toxic, they are not benign and without metabolic dysregulation consequences.

New studies in PubMed are cropping (pun intended) up in number pointing directly to insulin resistance, obesogenic, neurologic and inflammatory damage secondary to this broad group of pervasive chemicals known as persistent organic pollutants (POPs). They are difficult to avoid as once in the soil, air or bodies of water, fish, birds and animals, they typically fail to degrade and significantly impact the environment.

The researcher Alavanja states 'Over 1 billion pounds of pesticides are used in the United State (US) each year and approximately 5.6 billion pounds are used worldwide (1). In many developing countries programs to control exposures are limited or non-existent. As a consequence; it has been estimated that as many as 25 million agricultural workers worldwide experience unintentional pesticide poisonings each year (4). In a large prospective study of pesticide users in the United States, the Agricultural Health Study, it was estimated that 16% of the cohort had at least one pesticide poisoning or an unusually high pesticide exposure episode in their lifetime (5).

Although attempts to reduce pesticide use through organic agricultural practices and the use of other technologies to control pests continue, exposure to pesticides occupationally, through home and garden use, through termite control or indirectly through spray drifts and through residues in household dust, and in food and water are common (6). The US Department of Agriculture has estimated that 50 million people in the United States obtain their drinking water from groundwater that is potentially contaminated by pesticides and other agricultural chemicals (7, 8). Children from 3-6 years old received most of their dermal and non-dietary oral doses from playing with toys and while playing on carpets which contributed the largest portion of their exposure (9-12).'








U.S.A. Obesity Trends With Pesticide Use

Guess what?

Pesticide use on crops grown in the South (tobacco) and Mid-West (corn, wheat, soy) trends well with U.S.A. obesity patterns [hat tip: LePine MD]. Above is the trend of obesity that starts mid-1980s then grows exponentially each few years. Maps are from Lim et al and BFRSS data.

Smart people in Korea (Lim et al) report that 'There is an apparent overlap between areas in the USA where the herbicide, atrazine (ATZ), is heavily used and obesity-prevalence maps of people with a BMI over 30. Given that herbicides act on photosystem II of the thylakoid membrane of chloroplasts, which have a functional structure similar to mitochondria, we investigated whether chronic exposure to low concentrations of ATZ might cause obesity or insulin resistance by damaging mitochondrial function.'




Pesticides Kill Pests, Including Our Bug-like Mitochondria

It's therefore not surprising to read about the toxic effects of pesticides on pests whose networked pathways overlap almost precisely with our own cells. Atrazine is a mitochondrial toxin, and our mitochondria are the sole energy generators and powerhouses whether the substrate is glycogen, glucose or fatty acids.




Mitochondrial Dysfunction Causes Fatness and Insulin Resistance (IR)

'A close association between mitochondrial dysfunction and insulin resistance is well established [1]–[3]. In in vitro studies, we found that artificial induction of mitochondrial dysfunction induced insulin resistance [4], [5].' This is discussed by Lim et al. He and his colleagues performed an experiment on rodents. They fed low levels of atrazine to rats then examined lab parameters for insulin resistance (IR). What happened? The higher the dose of atrazine, the higher the obesity and insulin resistance. Atrazine was associated with mitochondrial dysfunction, higher visceral (organ) fat deposition, higher blood glucoses and decreased energy metabolism.

Another group of researchers, Ruzzin et al, tested a similar hypothesis. They fed crude Atlantic salmon oil to rodents and examined IR parameters. They state 'POPs accumulate in the lipid fraction of fish, and fish consumption represents a source of POP exposure to humans (Dougherty et al. 2000; Hites et al. 2004; Schafer and Kegley 2002). Therefore, certain European countries have dietary recommendations to limit the consumption of fatty fish per week (Scientific Advisory Committee on Nutrition 2004).' They discovered similar insulin resistant results when they exposed fat cells in vitro to a POP mixture that mimicked the relative abundance of contaminants found in crude salmon oil. Insulin signalling was broken and impaired.

Major Demything...


XerXes
'Cell Progression'
Photography from a hot-air ballon by Yann Arthus-Bertrand



"With Earth from above, I simply want people to see the Earth as it is today, as faithfully as possible. What motivates me is the impact a photograph can make within the framework of environmental preservation. The great novelty of our time is that mankind has the power to change its environment and I want my photos to testify to this fact so people can realise this."

--Yann Arthus-Bertrand



Demything Myths in My Mind

A couple of things I harass and harp on are now shaded in grey instead of the archetypical black-white which I tend to prefer for simplicity and reductionism. My kids eat gluten (at school and parties) and in choosing my battles, I've accepted certain facts of life. They're going to be exposed, they like it and we just all have to do our best. And our best is a template based on strictly relative terms (e.g. my mood). Gluten is definitely a struggle stillsince it permeates all restaurant food and sauces. On alibaba.com, one can purchase cheap bags of high-protein (high-toxicity) hybridized modern wheat or maize gluten (vital wheat gluten 75% of total protein wet content) in which a restaurant, supplier or large-scale cook can 'doctor up' their goodies. Gluten imparts many favorable food benefits: moisure, 'perfect viscoelasticity', taste, addiction, bounciness, baked good fluffiness, sauce thickening, dough extension, sausage filler, meatball tenderness (lionhead casseroles are infamous), petfood 'protein', etc.

With all that said, since moving to Shanghai, quite honestly I have been surprised by the number of people aware of gluten intolerance and progressive in that manner, and grateful that the volume of gluten is far less here in China than the USDA-Big Agra-permeated culture of the U.S.

Anyway. Call me skeptical today...



Seven (Paleo) Myths that I've Slowly Come to Highly Suspect

1. Gluten is 100% bad and toxic
--Demyth: Not for everyone (especially if no intestinal permeability), every moment, every minute, every dose

2. Dairy is non-paleo
--COME ON. Human variance, intestinal permeability, status of DPP-IV (casein enzymes) and gut flora determine this. Same with gluten...

3. Intermittent fasting is 100% safe
--See prior adrenal tagged posts. Martin Berkham fanboys [I'm jealous of y'lls kevlar-coated adrenal glands] may go please very gently f*ck yourselves...and continue cortisol-inducing yo-yo dieting and eating cheesecake. Sorry. #FAILEO if one has f*cked up adrenals.

4. VLC/ketosis is 100% safe
--Demyth: see above

5. High glycemic index safe starches are 100% safe
--Demyth: high GI carbs can induce inflammatory cascades of gene expression. For who? See the FUNGENUT study. I dunno...

6. Low carb (less than 200 grams/day) or VLC/ketosis induces 100% fat loss
--Demyth: it depends on hormones and insulin sensitivity(primarily adrenal/NE/EPI and anabolic ones, progesterone and testosterone and if there is excessive E or xenoestrogens). See Ebbeling Ludwig et al JAMA 2007; side figure those who exhibit decent insulin sensitivity (maintain low insulin after 75 grams of lines of glucose) can lose weight on any kind of diet (this study used hypocaloric, low GI, 170 g v. 220 g carbs). IR=insulin resistance

7. High glycemic index safe starches (white stuff -- lines of dextrose, white rice, white modern potatoes, table sugar, etc) induce 100% optimal health and fat loss
--I'm ambivalent because I cannot and I know a lot people who this is the case. Why? Hormone fluxes are sometimes OFF and subOPTIMAL. Who loses fat and gains optimal health with higher glycemic loads and higher GI foods? I've seen this work well in the athletic, the insulin sensitive and the ones who perform high or decent volume glycolytic activity. See Poliquin on Carb Intake to Meet Glycolytic Repetition Volume. Also gotta see Sloth and Astrup.




What I Do Know

1. Modern wheat is SUPER TOXIC, SUPER ADDICTIVE, SUPER FATTENING, SUPER INFLAMMATORY

2. Modern wheat contains an estimated SEVERAL HUNDREDS-FOLD more (toxic) proteins than heirloom or non-hybridized wheat

3. The USDA is playing a joke on us... I don't trust the pyramid or anything else they purport, especially if it involves Monsatan or their former executives who now frequently staff places like the FDA or EPA (Environmental 'Protection' Agency). BRILLIANT.

4. If intestinal permeability exists, you'll be guaranteed suboptimal health, chronic sublethal infections and significant levels of cellular inflammation which may or may not ever be detectable by standards of non-integrative medicine

5. Pharmaceuticals generally do not work and in fact worsen. The worse pharmaceuticals cause long-range adverse effects on intestinal permeability and endogenous hormone fluxes (broad spectrum antibiotics, Z-paks, proton pump inhibitors, acid blockers, oral birth control, synthetic hormones, glucocorticoids, prednisone, etc)

6. Too much sugar is toxic, addictive, fattening and inflammatory. When I'm not stressed out and working out a ton, I can do sugar with relative impugnity. YET. During certain times of my menstrual cycle or when I am not strenuously working out, I notice if I hit (some) sugar (e.g. organic palm, organic coconut sugar, white stuff, etc) then I will inevitably want to do lines of crack/sugar over and over and over and over infinitum again (e.g. candy cigarettes or almond flour pound cake or cookies).

7. Everything makes horrorific sense in light of evolution

8. Bell shaped curves -- I like these; these typically represent well

9. I don't need RCTs to tell me the sky is blue or that something makes sense
(sometimes the ridiculousness in Pubmed makes me throw my hands up)

10. We're omni-whores, consumers of everything and we still survive
