Vandana Shiva: Quack

Vandana Shiva, Quack

Vandana Shiva, Quack

We’ve already looked at the promotion of pseudoscience to gain wealth and power by Vani Hari “Food Babe,” Mike Adams, and Dr. Oz. On the international scene, there’s an even more dangerous person: Vandana Shiva, wealthy promoter of food fear and anti-GMO pseudoscience.

Human beings have an innate fear of contamination (dirty or diseased food, for example.) Modern quacks play on this by targeting unfamiliar food ingredients or agricultural techniques for demonization; it is quite easy to make scientific-sounding allegations about unknown chemical names or genetic engineering techniques, present yourself as the heroic bearer of truths food businesses want to repress, and then reap the benefits of power and wealth that come from your skill at swaying the easily hoodwinked.

The New Yorker has a wonderful deep-dive story on Vandana Shiva by Michael Spector. If you don’t have time to read it all, here’s some good bits:

Shiva has a flair for incendiary analogies. Recently, she compared what she calls “seed slavery,” inflicted upon the world by the forces of globalization, to human slavery. “When starting to fight for seed freedom, it’s because I saw a parallel,” she said at a food conference in the Netherlands. “That time, it was blacks who were captured in Africa and taken to work on the cotton and sugarcane fields of America. Today, it is all of life being enslaved. All of life. All species.”

Shiva cannot tolerate any group that endorses the use of genetic engineering in agriculture, no matter what else the organization does, or how qualified its support. When I mentioned that Monsanto, in addition to making genetically engineered seeds, has also become one of the world’s largest producers of conventionally bred seeds, she laughed. “That’s just public relations,” she said. She has a similarly low regard for the Bill and Melinda Gates Foundation, which has taken strong positions in support of biotechnology. Not long ago, Shiva wrote that the billions of dollars the foundation has invested in agricultural research and assistance poses “the greatest threat to farmers in the developing world.” She dismisses the American scientific organizations responsible for regulating genetically modified products, including the Food and Drug Administration, the Environmental Protection Agency, and the United States Department of Agriculture, as little more than tools of the international seed conglomerates.

At times, Shiva’s absolutism about G.M.O.s can lead her in strange directions. In 1999, ten thousand people were killed and millions were left homeless when a cyclone hit India’s eastern coastal state of Orissa. When the U.S. government dispatched grain and soy to help feed the desperate victims, Shiva held a news conference in New Delhi and said that the donation was proof that “the United States has been using the Orissa victims as guinea pigs” for genetically engineered products. She also wrote to the international relief agency Oxfam to say that she hoped it wasn’t planning to send genetically modified foods to feed the starving survivors. When neither the U.S. nor Oxfam altered its plans, she condemned the Indian government for accepting the provisions.

On March 29th, in Winnipeg, Shiva began a speech to a local food-rights group by revealing alarming new information about the impact of agricultural biotechnology on human health. “The Centers for Disease Control and Prevention has said that in two years the figure of autism has jumped from one in eighty-eight to one in sixty-eight,” she said, referring to an article in USA Today. “Then they go on to say obviously this is a trend showing that something’s wrong, and that whether something in the environment could be causing the uptick remains the million-dollar question.

“That question’s been answered,” Shiva continued. She mentioned glyphosate, the Monsanto herbicide that is commonly used with modified crops. “If you look at the graph of the growth of G.M.O.s, the growth of application of glyphosate and autism, it’s literally a one-to-one correspondence. And you could make that graph for kidney failure, you could make that graph for diabetes, you could make that graph even for Alzheimer’s.”

Hundreds of millions of people, in twenty-eight countries, eat transgenic products every day, and if any of Shiva’s assertions were true the implications would be catastrophic. But no relationship between glyphosate and the diseases that Shiva mentioned has been discovered. Her claims were based on a single research paper, released last year, in a journal called Entropy, which charges scientists to publish their findings. The paper contains no new research. Shiva had committed a common, but dangerous, fallacy: confusing a correlation with causation. (It turns out, for example, that the growth in sales of organic produce in the past decade matches the rise of autism, almost exactly. For that matter, so does the rise in sales of high-definition televisions, as well as the number of Americans who commute to work every day by bicycle.)

Shiva refers to her scientific credentials in almost every appearance, yet she often dispenses with the conventions of scientific inquiry. She is usually described in interviews and on television as a nuclear physicist, a quantum physicist, or a world-renowned physicist. Most of her book jackets include the following biographical note: “Before becoming an activist, Vandana Shiva was one of India’s leading physicists.” When I asked if she had ever worked as a physicist, she suggested that I search for the answer on Google. I found nothing, and she doesn’t list any such position in her biography.

“Shiva is lionized, particularly in the West, because she presents the romantic view of the farm,” Conway said. “Truth be damned. People in the rich world love to dabble in a past they were lucky enough to avoid—you know, a couple of chickens running around with the children in the back yard. But farming is bloody tough, as anyone who does it knows. It is like those people who romanticize villages in the developing world. Nobody who ever lived in one would do that.”

Everyone had a story to tell about insecticide poisoning. “Before Bt cotton came in, we used the other seeds,” Rameshwar Mamdev told me when I stopped by his six-acre farm, not far from the main dirt road that leads to the village. He plants corn in addition to cotton. “My wife would spray,” he said. “She would get sick. We would all get sick.” According to a recent study by the Flemish Institute for Biotechnology, there has been a sevenfold reduction in the use of pesticide since the introduction of Bt cotton; the number of cases of pesticide poisoning has fallen by nearly ninety per cent. Similar reductions have occurred in China. The growers, particularly women, by reducing their exposure to insecticide, not only have lowered their risk of serious illness but also are able to spend more time with their children.

“Why do rich people tell us to plant crops that will ruin our farms?” Narhari Pawar asked. Pawar is forty-seven, with skin the color of burnt molasses and the texture of a well-worn saddle. “Bt cotton is the only positive part of farming,” he said. “It has changed our lives. Without it, we would have no crops. Nothing.”

The all-encompassing obsession with Monsanto has made rational discussion of the risks and benefits of genetically modified products difficult. Many academic scientists who don’t work for Monsanto or any other large corporation are struggling to develop crops that have added nutrients and others that will tolerate drought, floods, or salty soil—all traits needed desperately by the world’s poorest farmers. Golden Rice—enriched with vitamin A—is the best-known example. More than a hundred and ninety million children under the age of five suffer from vitamin-A deficiency. Every year, as many as half a million will go blind. Rice plants produce beta carotene, the precursor to vitamin A, in the leaves but not in the grain. To make Golden Rice, scientists insert genes in the edible part of the plant, too.

Golden Rice would never offer more than a partial solution to micronutrient deficiency, and the intellectual-property rights have long been controlled by the nonprofit International Rice Research Institute, which makes the rights available to researchers at no cost. Still, after more than a decade of opposition, the rice is prohibited everywhere. Two economists, one from Berkeley and the other from Munich, recently examined the impact of that ban. In their study “The Economic Power of the Golden Rice Opposition,” they calculated that the absence of Golden Rice in the past decade has caused the loss of at least 1,424,680 life years in India alone. (Earlier this year, vandals destroyed some of the world’s first test plots, in the Philippines.)

Note the pattern: a wealthy elite use populist politics (based on feeding the fears of the ignorant) to gain more power for themselves. If their programs (no trade or technology, local sources only, no intellectual property) were ever to be implemented, billions would starve and the world would revert to a static, repressive subsistence economy. The damage they do by preventing development of better crops and agricultural methods, as well as blocking trade and investment wherever they can, is already enormous. Can we call this evil? You could argue that such memes are well-meaning and continue to flourish because of a lack of understanding of complex economic systems and trade webs; for example, Gandhi’s emphasis on village self-sufficiency (“A free India for Gandhi meant the flourishing of thousands of self-sufficient small communities who rule themselves without hindering others. Gandhian economics focused on the need for economic self-sufficiency at the village level.”) was at the time motivated by antipathy to a British India’s mercantilist exploitation of poor Indian farmers. But to argue this today when only agricultural technology saved millions from starvation in the late 1960s (when Norman Borlaug’s improved wheat varieties doubled the subcontinent’s wheat production) is worse than irresponsible.

Reason’s science writer Ron Bailey decries her in a much quicker read. A few good bits:

I have long been tracking the career of lies and disinformation that constitute the anti-intellectual trajectory of virulent anti-biotech activist Vandana Shiva. For example, back in 2001, I reported:

Ten thousand people were killed and 10 to 15 million left homeless when a cyclone slammed into India’s eastern coastal state of Orissa in October 1999. In the aftermath, CARE and the Catholic Relief Society distributed a high-nutrition mixture of corn and soy meal provided by the U.S. Agency for International Development to thousands of hungry storm victims. Oddly, this humanitarian act elicited cries of outrage.

“We call on the government of India and the state government of Orissa to immediately withdraw the corn-soya blend from distribution,” said Vandana Shiva, director of the New Delhi-based Research Foundation for Science, Technology, and Ecology. “The U.S. has been using the Orissa victims as guinea pigs for GM [genetically modified] products which have been rejected by consumers in the North, especially Europe.” Shiva’s organization had sent a sample of the food to a lab in the U.S. for testing to see if it contained any of the genetically improved corn and soy bean varieties grown by tens of thousands of farmers in the United States. Not surprisingly, it did.

“Vandana Shiva would rather have her people in India starve than eat bioengineered food,” says C.S. Prakash, a professor of plant molecular genetics at Tuskegee University in Alabama.

Writer Mary McCarty famously said of Lillian Hellman: “Every word she writes is a lie, including ‘and’ and ‘the’.” Nothing truer could be said of Shiva.

In a superb article, International Center of Genetic Engineering and Biotechnology researcher Anand Ranganathan nicely summarizes Shiva’s legacy of dishonesty and outright fabrication. Below are some representative quotations from Shiva along with some analysis by Ranganathan:

Shiva: “Science and masculinity were associated in domination over nature and femininity, and the ideologies of science and gender reinforced each other. The witch-hunting hysteria which was aimed at annihilating women in Europe as knowers and experts was contemporous with two centuries of scientific revolution. It reached its peak with Galileo’s Dialogue…”

Shiva: “Scientific missions colluded with religious missions to deny rights to nature. The rise of mechanical philosophy with the emergence of the scientific revolution was based on the destruction of concepts of a self-regenerative, self-organising nature which sustained all life. Just as technology changes seed from a living, renewable resource into mere raw material, it devalues women in a similar way.”…

So she is also a Third-Wave feminist: appeals to emotion and victimhood replace reason and science, though she pretends to be a scientist. Technology is supposedly a tool of the Patriarchy and oppresses women!

This tide of unreason, funded by governments, foundations, NGOs, and academia, threatens the future progress of humanity.

More on Diet Drinks: Best Studies Show They Aid Weight Loss

Sugar in Processed Foods

Sugar in Processed Foods – UCSF

One theme we’re going to return to over and over here is the bad science we see in media every day. Media needs content, so even bad studies with no control groups and self-reporting are trumpeted as news, which is one reason why we are assaulted by supposed proof of a diet or health question one day, then fed “proof” of the opposite the next. It’s all to keep you clicking and getting views to pay for the news site; the study promoters want the world to think their results are meaningful so they’ll get funding to do more. Incentives to hype are great, and so hype is what we get.

You can learn to read the studies for yourself to understand which to pay attention to. Or you can read specialty publications that have a record of understanding how real science works so you can rely on them when they say a study’s conclusions are really valid. That’s what I’m trying to do here — I read all the press releases so you don’t have to.

Today’s example is a large meta-analysis by Paige Miller and Vanessa Perez of the Center for Epidemiology, Biostatistics, and Computational Biology, Exponent Inc., published in The American Journal of Clinical Nutrition. A meta-analysis is a statistical study of a basket of other studies which attempts to discern a better answer to questions raised than the individual studies by combining them; techniques for doing this are complex, but the usual result is to quantify a trend in answers over a much larger examined population. The abstract [with my annotations]:

Background: Replacement of caloric sweeteners with lower- or no-calorie alternatives may facilitate weight loss or weight maintenance by helping to reduce energy intake; however, past research examining low-calorie sweeteners (LCSs) and body weight has produced mixed results. [They will go on to show only unreliable studies show diet drinks induce weight gain.]

Objective: The objective was to systematically review and quantitatively evaluate randomized controlled trials (RCTs) and prospective cohort studies, separately, that examined the relation between LCSs and body weight and composition. [A prospective cohort study identifies a sample, characterizes each element of the sample typically by measuring or questioning, then follows the sample to try to show what initial conditions lead to what outcomes.]

Design: A systematic literature search identified 15 RCTs and 9 prospective cohort studies that examined LCSs from foods or beverages or LCSs consumed as tabletop sweeteners. Meta-analyses generated weighted mean differences in body weight and composition values between the LCS and control groups among RCTs and weighted mean correlations for LCS intake and these parameters among prospective cohort studies.

Results: In RCTs, LCSs modestly but significantly reduced all outcomes examined, including body weight (−0.80 kg; 95% CI: −1.17, −0.43), body mass index [BMI (in kg/m2): −0.24; 95% CI: −0.41, −0.07], fat mass (−1.10 kg; 95% CI: −1.77, −0.44), and waist circumference (−0.83 cm; 95% CI: −1.29, −0.37). Among prospective cohort studies, LCS intake was not associated with body weight or fat mass, but was significantly associated with slightly higher BMI (0.03; 95% CI: 0.01, 0.06). [Emphasis mine: only the unscientific prospective cohort studies showed weight gain for diet drink consumers.]

Conclusions: The current meta-analysis provides a rigorous evaluation of the scientific evidence on LCSs and body weight and composition. Findings from observational studies showed no association between LCS intake and body weight or fat mass and a small positive association with BMI; however, data from RCTs, which provide the highest quality of evidence for examining the potentially causal effects of LCS intake, indicate that substituting LCS options for their regular-calorie versions results in a modest weight loss and may be a useful dietary tool to improve compliance with weight loss or weight maintenance plans.

So what we can see here is that self-promoters who wanted to show low-calorie sweeteners had negative effects on body weight and metabolism were citing poor, uncontrolled studies. They explained this supposed effect by claiming these sweeteners confused metabolism by triggering insulin release through their effect on taste buds, but there was no evidence of that. One plausible explanation for the studies showing weight increases for those who reported drinking diet sodas is that such people are already aware of their tendency toward weight gain, and are more likely to consume diet drinks as a result; other factors about them create the weight gain, and their knowledge of their propensity to gain weight is the cause for their choosing to drink diet sodas. Those other causes of weight gain continue during the study, so naturally this population gains more weight than the unconcerned.

Our meta-takeaway from the meta-analysis: correlation is not causation. If you personally want to change some practice or undergo a procedure to improve something about yourself, pay very little attention to studies which are not randomized, controlled trials or their equivalent. Another good example of this is the constant drumbeat of Conventional Wisdom claiming that going to college increases your future earnings; the figures cited are almost always ignoring the fact that people who complete college have thereby been screened for aptitude for admission and then screened again for the ability to stick to a plan. If you are trying to decide whether or not to go to college, your aptitude and fortitude are already determined, and the effect of going vs. not going for you is much less, especially when you evaluate the opportunity costs: what you could be doing instead of college to educate yourself and grow your earnings capacity. Some people (and you might be one of them) would earn more by starting their own business or going to a high tech startup and skipping higher education. Not that earnings are the most important thing; one common pattern is to gain admission to a prestigious school with excellent networking connections and use those ties to jump into a business without bothering to finish school (the route of Bill Gates and many other entrepreneurs.)

Learn to recognize the lies and distortions in the Conventional Wisdom, and chart your own course.

Now it’s likely true that simply drinking water or tea instead of any soft drink is the healthiest option. But for those who appreciate the carbonation and sweet taste of a diet soda, you should feel free to indulge, in moderation. Diet sodas are far better for your body than sugared sodas, large servings of fruit juice, or jazzy Starbucks or Jamba Juice concoctions.

Bulletproof Coffee: Coffee, Oil, and Butter for Breakfast?

I’ve been aware of Dave Asprey’s “Bulletproof” brand of coffee, laced with special oil and butter, for some time. It’s an intriguing idea, promising that a tasty, buttery cup of coffee can clear your head faster and replace a good breakfast for workers who want to start their day at maximum mental speed. Since he’s an Internet promoter like Vani Hari “Food Babe,” I was suspicious but never investigated — I like to see an underdog contest the conventional wisdom, and we now know a dose of butter with breakfast does no harm. But what about the lack of protein in his ketogenic breakfast?

Fast Company has a good story by Chris Gayomali, who tried out the (expensive) entrepreneur’s special coffee kit:

Separately those ingredients don’t exactly tick all the traditional boxes for a balanced breakfast. But together they are the three components you need to make Bulletproof coffee, a frothy, energy-igniting beverage that has surged in recent years to become the toast of Silicon Valley. Its promises are multitude, at least according to its creator, cloud-computing pioneer and “Bulletproof Executive” Dave Asprey, who refined his recipe after trying a tea made with yak-butter in Nepal.

Among Bulletproof coffee’s listed benefits: It triggers weight loss by way of ketosis, a metabolic state triggered by a lack of carbs that kicks fat-burning into overdrive; it kills pesky cravings; and it boosts cognitive function, mainlining a shining dose of mental clarity into your foggy morning skull. Maybe it would even fold my laundry.

Most of all, though, Bulletproof coffee is intended to be efficient, an easy way for the biohacking crowd to slurp down fats and calories (460 of them!) without so much as sniffing a processed carbohydrate. Why eat a muffin that goes straight to your muffin top, the thinking goes, when you could drink down the metabolic equivalent of supercharged battery acid every morning?

Quite right about the muffins. Starbucks has been seducing on-the-go workers with sugar-laden baked goods to go with their quick coffee drinks (many of them also sugar-laced) for years now. The result has been fatter customers who barely realize how much sugar they’re consuming. As for clarity of thought, it’s likely a dose of stimulant and digestible fats will leave you mentally clearer than a heavy meal with protein, but also likely that you will run out of fuel before lunchtime. Meanwhile, Asprey claims his coffee is specially processed to remove harmful fungal toxins; this is one mark of the quack, the claim that only his product has some special quality and the rest are poison. Otherwise, you could avoid paying him premium prices and mix your own coffee-butter-oil concoction. Joe Rogan, who runs a popular broadcast, was apparently taken in and then disillusioned:

I fell down a rabbit hole. Apparently Asprey had appeared on Rogan’s podcast a few days prior, expounding on Bulletproof’s many miracles. Ever the charmer, Asprey had converted a wide-eyed Rogan to the Church of Grass-Fed Butter, and Rogan would go on to sing BPC’s praises anywhere he had a pulpit.

The singing didn’t last long, though. Rogan soon discovered that one of Asprey’s key claims–that 70% of all coffee beans were laced in vitality-sapping mycotoxins, which he claimed also makes coffee bitter–turned out to be false.

“Good coffee providers know how to eliminate this from coffee,” Rogan said on his show, citing a study he found on PubMed from the 1980s. “They’ve been able to solve it [for decades] with something called wet processing.” When the coffee plant’s berries are picked, the cherry (or bean) is “washed” in running water before it’s left to ferment and dry, reducing mycotoxin levels to negligible amounts. Everyone from Stumptown to Starbucks washes their beans this way.

That’s why Rogan was pissed. He felt betrayed, and accused Asprey of spouting pseudoscience veiled as fact. “There’s some bullshit there, for sure,” he said. “He used my platform in a way that’s non-ethical.”

Then there’s the lack of staying power in a meal of only coffee and fat (butter and the special oil, which has medium-chain triglycerides which are easily digested.) Your body needs protein, especially after 12 hours without a meal, and a breakfast without protein will have your body starving your muscle mass to sustain itself. The reporter noticed that he grew weak with hunger long before lunch:

“I would most certainly not recommend it,” says Christopher Ochner, a nutrition expert at the Icahn School of Medicine at Mount Sinai Hospital. “Now there is a little bit of data on the use of medium-chain triglycerides for weight loss and regulating cholesterol. But the effect is very, very small.”

A few days after the experiment concluded, I asked Dr. Ochner why I was still hungry after drinking down hundreds of calories worth of saturated fat every morning. “Well, that’s not actually surprising,” he says. “The people making these claims know there’s a lot of evidence that drinks and shakes don’t really make people feel full. Even if you drink a big Coke with your meal or whatever, and that could be 400 calories or more, it doesn’t really make a huge dent in people’s appetite. It’s the same concept.”

I wouldn’t recommend this kind of breakfast, though a bit of cream or butter in your coffee would not hurt. At least have two eggs or some fish along with it to supply needed protein.

LeBron James Cut Carbs for Lean Look

LeBron James Skinny

LeBron James Skinny

Just confirmation that word is spreading — if you want to lower your body fat percentage and start looking lean and defined, cutting carbs way down or completely out is the way to go. The Wall Street Journal reports in their story “Why LeBron James Is Suddenly Skinny” that the basketball star sports a new lean look after a summer cutting carbs:

The basketball world has been buzzing lately about an unexpected decision LeBron James made this summer. It has already had sweeping effects across the NBA, and it has radically changed how everyone sees the sport’s biggest star.

He cut carbohydrates from his diet.

James, who also opted last month to leave the Miami Heat for his hometown Cleveland Cavaliers, has shed a noticeable amount of weight since going on a summer-long carbohydrate cleanse not long after losing in the NBA Finals to the San Antonio Spurs in June.
