Energy Economics Behind Food Digestion

Since digestion takes energy, it is helpful to think about the "cost to revenue ratio" (fuel efficiency) of foods that we eat


We all realize on some level that food is very similar to a drug. When hunger sets in, withdrawal symptoms become apparent. Confusion, decreased mental functioning, weakness, nausea, unpleasant moods, negative perception of the world/humanity, etc. When we finally get a chance to eat again, what we all want is for the molecular building blocks within food to reach and become part of our key bodily systems as quickly and efficiently as possible. There are simple mathematics behind digesting fuel that should be kept in mind.

Digestion takes caloric energy. Eating food drains us to a degree that is dependent on the resistance of the food to intestinal acids. If the food is more difficult to digest it'll take more bodily energy to break it into molecular building blocks for the body. This in turn will result in one's body not operating at peak levels. Here's 2 examples to illustrate (the numbers are randomly selected for clear cut demonstration):

A) A deep fried blob of meat is stuffed with 1000 units of energy and it takes the body 500 units of energy to break it down over a period of 5 hours. This produces an average of 100 units of energy per hour for the body over 5 hours (1000-500)/5. The average ratio of energy cost to revenue is 1 to 2. If this food is dumped into a ravenous energy deprived body, then energy will be pulled from other areas of the body to begin the digestion. This will be manifest with muscle tiredness, coldness (energy diverted from heating systems to the stomach), and even lack of tangible cognitive improvement within first hour after eating. Thus the initial ratio of energy cost to revenue can even cancel each other out. Not the drug "fix" one is looking for. We want to squeeze more out of our business.

B) A bowl of cold quinoa salad with various nuts and berries is only stuffed with 500 units of energy. It takes 100 units of energy to digest it over 1 hour. Body gets 400 units of energy in this time. Ratio of energy cost to revenue here is 1 to 5. Since the powerful acids in the stomach can immediately rip apart the cold salad into building blocks, this means a rapid huge boost of energy from acceleration of cognitive and physical functioning. Molecular building blocks are quickly transported via blood stream to reinforce every key system in the body. The negatives of such a quick and efficient fix is that the energy high wears off after an hour leading to rather rapid onset of hunger and noticeable physiological slowdown. The business is very profitable but has to be fed at a breakneck rate that is not always sustainable.

Proper utilization of energy economics in food can allow an individual to achieve the equivalent of a coffee boost (from nutritious food that has weak cell lining allowing the body to make short work of it). Our bodies are the most complex wonderful machines we have access to. Do we put nasty poorly treated gasoline into a high end sports car? No, since we understand that it requires immediate high performance. An advanced jet airplane requires specialized jet fuel for maximum ratio of energy cost to revenue.

So why do many people treat their bodies worse than they treat their cars? Besides the socioeconomic factors behind it, there are also practical considerations. Food that is less efficient to digest has a release of energy that can be described as "extended release" in pharmacological terminology. A slice of pepperoni pizza will provide hours of inefficiently acquired energy. Of course if one has a powerful metabolism, one can pump lots of high energy inefficient food into the system and even get a caloric rush after some digestion has already occurred. Combined with the fact that such foods are often solid liquor buffers, it becomes a no brainer. Fuel like quinoa will not only be a poor buffer but its effects will constantly and annoyingly run out. Nobody wants to carry a grain basket with them. Of course in the long term, the heavy fuel will corrode/clog up the system and become increasingly counterproductive as the human machine is now expanding energy units to support heavier weight with all the health ailments associated with it.

However when it comes to day to day life and wanting to be at peak cognitive and emotional levels, digestive efficiency has to be kept in mind. Proper combination of the two types of fuel can result in relatively quick onset of good cheer and solid functioning (energy release from say, quinoa being immediately rerouted to help neutralize weakening from digestion of heavy fuel) without a crash or desire for an afternoon siesta.

Lack of Accessible Non-Damaging Healthy Food

Logistics of United States create an insurmountable nutritional gap between the economic classes. Junk food in turn contributes to economic divide by stifling brain function.




Basic food sustenance, along with basic literacy, has mostly been achieved in United States. One can almost say there aren't starving Americans in a superpower that is spending abroad for conquered societies. Obviously that isn't exactly the case, as seen by dramatic numbers of people who fall through the cracks. However even the homeless can scrape enough to get mass produced rice and bread. Starvation is not a problem as seen by the obesity rates of the poor (and corresponding drains on health infrastructure as well as stagnating life spans). Mission accomplished?

Not exactly. Try going to a gas station in rural areas of United States and finding anything that is healthy. Healthy is a rather vague term but lets work with a definition of a food that at least doesn't do harm. You might find some milk and low fat cheese or even eggs occasionally. Vast majority of what you'll find is tightly sealed in plastic and resembles military MRE ration packs. We're talking about food so full of preservatives, salts, and fats that it can survive indefinitely. When this type of food hits a ravenous stomach, the result is a lot of energy expanded by the body to just break it down and separate the molecules. We're all familiar at this point with the side effects of too much corn starch, sodium, sugars, salts, and de facto saturated fats (recent regulatory efforts against blatantly detrimental transfats just touch upon the tip of the iceberg). We're also familiar with nutrient deprived white bread, pasta, and rice that fills the hunger gaps in a lot of American population. Sure, rice and pasta cartons can say they are enriched with vitamins but one doesn't have to be a rocket scientist to see it's not the same vitamin level one would get from chickpeas, pricier grains, and fish.

A person determined to find non-detrimental food will run into a brick wall if he goes into a gas station, bus station, or an urban corner store. This brick wall would be humorous and surreal if one wasn't feeling weakness and bits of pain from hunger. You might argue that those places are designed for snacks and beer rather than food. That disregards the fact that millions of hungry people in need of breakfast, dinner, or lunch will do what it takes to prevent their stomach lining from being eaten further. They get their sustenance from these places out of circumstance, even if just to hold off the hunger until non-detrimental meal can be prepared.

How easy is to prepare a non-damaging meal? Most American supermarkets are larger versions of the gas stations and corner stores. The mega food markets are monuments to the sheer inefficiency of residential living in United States and a reason why more preservatives are put into food than necessary. Getting food (healthy as well as damaging) from the source to a person's mouth in a 4th largest country in the world ain't easy. The sheer logistics of getting it from the mega farms across hundreds or thousands of miles to the supermarkets necessitate additional preservatives and salts for storage.

It was one thing in early 20th century when food production was more decentralized and many people actually grew their own. It became another when people decided to live in first the urban areas and then suburbia to escape proximity to ethnic minorities in the inner cities. Suburban living and decline of the small farmer greatly increased the need to add life damaging preservatives to all manner of food. Food couldn't just be shipped by train to the cities but now needed to be also driven from offloading hubs to the suburban supermarkets. Large farms acquired state subsidies, tax breaks, and self sustaining political clout. Many emerging agricultural corporations then drove smaller farmers not qualified for such bailouts out of business and put food source out of proximity for many communities. Many would have done it with mass production and won the hearts of poorer consumers anyway. Now that the population has exploded we are seemingly stuck in this process.

Being stuck in a situation allows those making the rules and providing the food to abuse the system. Many people are not aware of basic tricks used by the industry. An example is adding coloring to beef and salmon to make them appear fresher and redder than they really are. There are many others but even the college educated don't want to watch (and shouldn't have to) out for corporate snake oil salesman. "Buyer beware" as a concept looses meaning when food distribution is approaching Soviet levels in terms of mass central planning, inefficiencies, and corresponding drop in quality.

Some things of course can be done. One is eliminating subsidies for things like corn which allow cement-like cornstarch to be artificially cheaper and used more widely to hurt millions of Americans. Then of course tax payers can foot the bill for subsidies for new categories of non-damaging foods like quinoa. It'll artificially make healthier ingredients in diners, restaurants, and supermarkets cheaper through mass production. The underlining logistical problem is not resolved however. Food quality will only improve through educated demand from segments of the population.

We already see the explosion of popularity of Wholefoods in urban areas. Pricey food acquired from a salad bar there does not give a sickening feeling to one's body compared to same amount spent on a meal from say, Applebees. A lot of the food found in these stores gives a feeling of energy as the stomach acids are able to rapidly absorb and integrate nutrients from fresh products. Wholefoods pays enormous amounts of rent in area like Manhattan. The endless lines of white people patiently standing there indicate that it will continue growing and the model is working. As it grows, there is bound to be a competitor with even healthier offerings and we should see this level of food quality reach most of the American population by 2020s. At that point however, the wealthier educated consumers will be buying even healthier designer food and the process will repeat.

This sounds optimistic and gives a nod to the power of the free market until we think about the gap that develops. There is a sinister aspect of a process where educated urban professionals eat healthier while the poor are stuck buying food that damages their bodies. Unhealthy processed food can prevent brain functioning at peak efficiency and even hurt long term mental functioning through lowering a person's neuroplasticity. The health costs of medical treatment from complications caused by poor nutrition also disproportionately fall on the poor. This elicits outraged screams from urban professionals about taxes to pay for others' mistakes.

Considering United States is a large country, the physical energy required to bring Whole Foods level quality to most urban areas is enormous. We see the education gap between the wealthier and poorer Americans continuously compounded by the nutritional gap that is never fully closed. Higher fertility rates of the poor would indicate that the health/nutritional gap is likely to grow in the years ahead as well as differences in life span and physiological functioning. In the old days the poor would have less caloric intake per day and it would stunt their growth and life. In the modern world there is plenty of calories to go around but the stunting of functioning manifests in other ways. A person who eats deep fried foods, Ramen, McDonalds, pizza, and energy drinks will not do as well when it comes to learning and passing exams compared to a person who eats grains, fresh fish, and juices. This is something that educational system reformists need to look at very seriously and from the perspective of improving mental functioning.

Added corrective costs of unhealthy lifestyle such as time/money on weight loss, doctor/hospital, and therapy, create additional burdens. Some American populations are extra vulnerable to further falling behind educationally and financially such as rural white evangelicals, blacks, and Hispanics. McDonalds and its competitors spend billions on annual advertising while hard liquor commercials are illegal. The new "I'm Loving it" McDonalds campaign blatantly tries to appeal to black culture since poor whites are slowly moving away from obviously damaging foods. The amount of preservatives in fast food are best illustrated with the amazing lack of deterioration of the "meat" patty over time.

A lot of muckraking has been done over the years on the food situation and logistics in this country. We are beginning to see some change with return of the small farmer under the organic umbrella. The change is rather slow considering the amount of information available and the political power of the large farms. The national level of nutritional quality is as likely to sharply improve as the Chinese police respecting Miranda rights 10 years from now.
