King Corn - Documentary

Couple of days back, I had a chance to watch the documentary, King Corn thru NetFlix “watch instantly” option. BTW – this worked very well. There was no disturbance/buffering when I watched it; it also “remembers" where I left when I resumed viewing in a different machine.

This movie is produced by 2 college grads – Ian Cheney and Curtis Ellis - alarmed by the obesity epidemic and ubiquitous presence of corn in almost all processed foods, they move from Boston, MA to Greene, Iowa to grow and farm an acre of corn. During this period, they try to trace the corn from fields to the food system and come across many troubling questions about how and what we eat.

Though the farming aspect of the film is slightly boring, the film makers have captured the viewer’s interest by graphically presenting the data on where the “manufactured” corn goes – to sweetener industry for High fructose corn syrup, to feed lots for cows and chickens for fattening etc. America has moved from small farm owners to big corporation thanks to the technology improvement in farming practices. For example, the movie shows/says that an acre of land takes about just 18 minutes to plant corn seeds. Corn yield per acre in 1970 was 86 Bushels whereas in 2007 - 180. Technological improvements in the farm yield, is direct result of farm subsidies (introduced thru the farm bill (1973) by Earl Butz) which makes farming corn a profitable one. This farm bill was instrumental in making the food cheaper and resulting in more disposable income available to amercian families.

If you take McDonald's meal, you don't realize it when you eat it, but you're eating corn. Beef has been corn-fed, Soda is corn. Even the French fries. Half of the calories in the French fries come from the fat they're fried in, which is liable to be either corn or soy oil. Everything in your plate is corn. - Michael Pollan, UC Berkeley, in King Corn

The upside of the farm bill is - food became cheaper and made americans to spend just 10% of their income on food in 2009 (from 22% in 1949) - one of the lowest in the world. Industrialization of food also made food available throughout the year. Politically, a noble and a electorally powerful goal too.

The reductions in cost and year round availability of food - took its toll on human health. All animals (cows, pigs, chickens) are made to eat just corn, because corn is made cheaper thru subsidies. These animals are not evolved to eat grains 100% (including humans, of course, but that is for a different day).

To quote from natural news on the effects of forced grain feeding for animals, "Ruminant cattle, like cows and sheep, possess a special digestive system in which grasses are converted into digestible nutrients. Unlike humans who are unable to properly assimilate grasses and their nutrients, these animals are able to convert the plant cellulose into protein and fats. The result is a meat composition of roughly a 1:1 ratio of omega-3 to omega-6 fatty acids with omega-3 dominating slightly.

Grains, disturbs the cow's digestive system that, unless done gradually, can kill the animal. "Feedlot bloat", a term used to describe the buildup of trapped gas in the rumen of the animal, is the primary reason why feedlot cattle must be fed antibiotics and hormones in order to keep them alive. Their digestive systems are unable to process the immense amounts of starch in their feed, turning their pH from neutral to acid and causing them to contract a myriad of diseases".

The health impact for humans are also discussed in the movie; Whether the corn gets to sweetener industry for High Fructose Corn Syrup or it gets to the cows/chicken/pigs as food – everything comes to us in the form of milk/yogurt/jelly/soda/bread/meat – what we consume. And it changes the human metabolism considerably causing life style diseases including Type II Diabetes and heart disease.

All in all, worth watching documentary and take an informed decision on what to consume.

Track your Plaque - Book Review

How often do we come across news wherein a friend or a relative suffered a heart attack and had to die all of a sudden?

Do you know that the conventional tests (HDL, LDL, Triglycerides, Total Cholesterol, Treadmill test) for assessing whether a person has a risk for future heart attack are woefully inadequate? Meaning, even after all the above are performed on time (with results are considered normal range) – still that person can experience a fatal/non fatal heart attack?

Very often we hear that an apparently otherwise healthy individual suffering from heart disease had to undergo bypass surgery or had to operate with stents etc.

If you want to find answers for this and to educate how to protect yourself – you have to read Track your Plaque book. Dr. William Davis addresses heart disease and what causes heart attacks, how we can identify the risk one has against heart disease, how we can improve upon those parameters through life style changes, diet and medicines.

Why this book? Don’t we have hospitals for cardiovascular care and incase if someone has heart disease – he/she can get better treatment in the hospital, why read this book and make changes to life style among other things?

From Dr Davis's own words - Cardiac care is big business. As a nation, US spent $59 billion on cardiovascular care per year (American Heart Association, 2002). Annual hospital revenues for bypass surgery total $25 billion. Thirty percent of hospital revenues and 50% of profits are from cardiac care. Heart care to a hospital is like the Accord is to Honda, or Windows is to Microsoft—it’s a hot seller.

We live in an age when hospitals measure their success by the number of coronary bypass surgeries they perform. Incredibly, it is still easier to get a bypass operation than it is to get good information on heart disease prevention. There are even billboards on the highways advertising bypass surgery.

Second – this book explains that plaque take decades to grow (for most people) in the arteries and by taking right steps and actions at the right time (not when taken to ER) – we can successfully regress it. This is not big money to you or for the hospital. You can achieve this at much lesser cost than a bypass or an operation involving stents etc. So hospitals are not going to be advertising preventative things to you and me over TV and media. There is no money for them in this. It is your responsibility to protect yourself.

This book explains that - non-invasive 10 min scanning of the arteries for calcium deposits using an Electron Beam Tomography (EBT) Scanner. Based on the scan results, the cardiologist will assign a risk score to the patient, and will order additional blood tests least of which is LDL, HDL, triglycerides and Total cholesterol. Not that they are not important. There are more “definitive” tests that can/need to be done today and identify our current state of Cardio parameters rather than relying on the same old LDL, HDL and triglycerides. A good result in LDL, HDL test does not mean that one is not going to have heart attack.

Based on those results – the patient can work with the Doctor and identify what needs to be done for improving the odds.

One thing I wanted to mention – in the changes that need to be done to improve health - food/fats – the Dr and the author Dr. William Davis argues against saturated fat. He castigates that saturated fat is unhealthy and is not required for the body. In fact it is just the opposite. Second he also says you can consume Canola oil which I do not agree. Vegetable oils (Corn oil, cottonseed, rapeseed etc) are a menace and humans are not evolved to consume that in industrial quantities, which we do . Third he also mentioned that Oat bran can be consumed – I am against it. Oats raise blood sugar and it cannot be good for anyone’s health including Cardio parameters. Recently William Davis wrote in his blog that he has changed his mind on Oats.

Dr. William Davis also runs a program called Track your Plaque. All of the concepts explained in the book – you can also have it done thru this program.

The key takeaway is - artery plaques can be identified in humans using non-invasive techniques, additional blood tests will need to be done to identify what caused the plaque, adopt life style including medicines, supplements and diet and you can regress the plaque.

A must read for anyone who is interested in staying healthy and not wanting to give a surprise to oneself or family.

Food Inc - A Review

Though this documentary is more related to the scenario in the US now, since we are opening up to MNCs everywhere, this could be our situation in no time.

Last week I had a chance to watch a documentary titled - Food Inc. The movie is co-produced by Eric Schlosser – author of the book "Fast Food Nation". In many sense, this is a video version of that book.

The documentary’s primary aim is to create awareness among the public and they have traced the food from their plate to its source. The documentary is a journey of the director and the travails he faces in this journey. Today, a curtain is in place between consumers and the “manufactured food”. And certainly, it is not in the interest of the general public.

Never before in the history of mankind, have we had 3 square meals everyday with certainty. Ever since WWII, the administration wanted to keep the food prices down and ensure that food is available in abundance. Favorable government policies on grain farming thru heavy subsidies, technological improvement and questionable practices have ensured year round availability of cheap food. Factory farming concentrates on making every product – faster, fattier and cheaper. Just a handful of companies are controlling our food today – right from seed to supermarket.

There are some unintended consequences of these actions –
1. Healthy calories have become expensive whereas unhealthy calories have become cheaper
2. Manufactured food – “sometimes” have E Coli or Salmonella infection – infecting people.
3. People do not know what they are eating - Genetically modified food does not need labeling
4. Obesity, Type II diabetes have skyrocketed – consume cheap food and pay for the consequences- in effect, the total cost of such food gets higher.

For example – the movie talks of Tomatoes – “plucked when they were green and made to ripen using ethylene gas. So what you see in the supermarket is not a real tomato – it is a notional tomato, an idea of a tomato”.

Since companies do factory farming – problems are being addressed at a micro level without caring about its impact on the health or seeing a big picture. In essence they are not manufacturing a product, they are making food.

For example – Farm subsidies have made grains like wheat, corn, etc very cheap and as a consequence companies that raise (and butcher) hens, cows and pigs, now only feed them corn – only corn. Evolutionarily these animals do not support ONLY grain based diet and hence they become fatter quicker, get infected with bacteria etc. When cows are infected, just feeding grass will make them shed 80% of such bacteria. Instead they are given anti-biotics.

Conventionally, it takes 90 days for a chicken to grow fully, now it takes just 47 days. They have also redesigned the chicken breast and made it larger so that those chickens are not able to withstand their own weight so much so that they do not walk inside the giant smelly barn.

The message is – people should go for organic produce, go buy from regular farmer’s markets and be involved on food access issues etc. Getting people involved can make the food industry change its ways. The tobacco industry was booted decades back like this. What is needed today is awareness about the issues in the food industry and a sentiment among public that is similar to the sentiment towards the tobacco industry.
