A few interesting things about lipids

In the course of the past few decades, fats have gotten a negative reputation. Even though reason seems to make a timid comeback, as carbohydrates have taken over the role of the bogeyman, there still is a stigma on fats. The real culprit is not fat as much as it is overconsumption beyond our actual nutritional and physiological needs of fats, of food, of calories, well… of pretty much everything in our great consumption society. I will not spend time on the overconsumption of fats, as it is mostly a case of gluttony and ignorance about nutrition. I will write the following lines to show why fats are important and contribute to make life fun.

First of all, fats do belong is a healthy balanced diet. Fats, which are part of the lipids as they are called in biology, are building blocks of cell walls of living organisms. Lipids play very important roles in our metabolism and biochemistry. They store calories, which is convenient when food is scarce, but they have many more roles. Cholesterol, a lipid with a terrible reputation, plays an essential role in the synthesis of steroid hormones, which in turn play a role in sexual hormones. Cholesterol also plays a role in the synthesis of vitamin D. Other lipids include mono-, di- and tri-glycerides and fatty acids, and their cohort of saturated, mono-unsaturated and poly-unsaturated types. We all have heard about essential fatty acids, in particular omega-3 type is quite a popular one, and about their importance for good health. Just take the time to do some research on those terms and you will see how important lipids are. It is not particularly difficult, although it can be sometimes tedious, so just take your time to browse information.

Just any other thing in life, too much is exactly that: too much. Excesses always bring problems. It is true for fats. It is also true for the popular protein group. Health and nutrition are about balance and proper amounts.

Butter or margarine?There are some interesting consequences of the fatty acid composition of edible fats. First what is meant by saturated or unsaturated relates to the presence (unsaturated) or absence (saturated) of double bonds in the molecule of a fatty acid. An unsaturated fatty acid molecule has the ability to combine with oxygen or other atoms. When a fat combines with oxygen, it becomes oxidized, which is commonly known as rancid, with the bad taste that goes with it. Saturated fats do not have bonds that can open and combine with other elements. They are more stable. And that was the whole idea of margarine as a substitute for butter. Butter, as you probably know, can get rancid, especially if it is not refrigerated. A way to avoid that is to add ß-carotene, an orange pigment and precursor of vitamin A, to the butter, which is common in the dairy industry. The purpose of margarine was to have a butter substitute that would not get rancid and to do that, the process consists of hydrogenating (adding hydrogen to) the fat. The double bonds open and attach hydrogen atoms, thus leaving no space to oxygen to attach and make the fat rancid. Basically, the original margarine was fully saturated fat. It is ironic to know that when in the same time the margarine industry did all it could to discredit butter, which is a rather complex mix of long and short fatty acids, although mostly saturated. And it is also interesting to see that over time, margarine producers actually produced vegetable fat spreads that mimic butter much more than the original margarine ever would. Since I am addressing the processing of fats, unsaturated fats can turn into two different types called Trans and Cis. We have all heard about the risks of Trans fats and they are banned about everywhere nowadays. Trans and Cis are two spatial molecular configurations of a same fatty acid molecule, depending on which side of the molecule the radical is. This tiny difference has serious implications for metabolism and health, though.

Another characteristic of fatty acids is their physical property. In particular, saturated fats are usually harder at room temperature than mono-unsaturated and even more so than poly-unsaturated, because they have a lower melting point. The more double bonds there are in the fatty acid chain, the softer, even the more liquid the fat/oil is. Also, the longer the chain, the harder the fat is, as their melting point is lower. To sum up and simplify a bit, the softer or more liquid a fat/oil is at room temperature, the healthier it probably is.

Another characteristic of fats is that the fat profile in the food will influence the profile in the body fat. This is important to understand in regard with animal farming. If farm animals eat a diet that contains more unsaturated fats, their body fat will also be more unsaturated. This means that their meat will have a more unsaturated profile, which is a rather positive thing for you as the consumer. Of course, here the rule is always the same: the diet must be balanced.

Animal products and fat is quite an interesting topic, and a rather complex one, too. Fatty meat used to be the preference (think bacon). Why? Simply because I am talking about times when people did not live in overheated houses and had physically demanding jobs. Animal fat was rich in calories, which were quite useful both to do hard work and to live in cool homes. As comfort improved and mechanization made many jobs physically less demanding, the need for these calories decreased. If they are not being burnt, they accumulate in the body. That is why a comfortable life requires fewer calories than a demanding life. Yet, different cultures, because of culinary tradition, deal differently with the fattiness of farm animals destined to produce meat. In the EU, production shifted towards leaner breeds of animals, as consumers did not want fatty meat. In North America, the approach has been a bit different. They like fatty meat but cut off the meat on the plate, or eat quite a bit of it. A disadvantage of producing fat animals is that it requires more energy for their body to produce a pound of fat than it does to produce a pound of muscle. Males (I am talking farm animals here) generally produce leaner meat than females, but castrated males tend to produce a fattier meat than females. Using hormones in animal farming has an effect, too. Since the hormones used are female hormones, animals tend to fatten more. From the producer’s perspective, it is a matter of what the market pays for what quality of meat. In the EU, leaner animals receive a better price, but it is not everywhere the same around the world. Hormones also help reduce the cost as fattening goes faster. Fast is nice, but the age of an animal influences how much fat it gets in its tissues. Just like humans, farm animals have mostly water in their body tissues when they are young. When they age, fat gradually replaces the water, and we all know that losing the love handles gets more difficult with age. It is the same thing with animals. It is complex but fun, isn’t it?

What we have on our plate is all about economics. Depending on what consumers buy, the economic differ, and so do farming systems. Depending on production systems and consumer demand, fattiness of animal products varies. Although most people will tell you that meat is protein, this is far from always true. There different grades of fattiness between regular, lean and extra lean ground meat, for instance. Fat percentages vary greatly, from 10% to 30% of total weight, to simplify. Protein will be around 20% for most meats, regardless of the species. Keep in mind the main ingredient of meat is water. Animal bodies consist of roughly 60% water. If you remove the water and take the dry matter equivalent, fat percentages on dry matter will vary between 25% and 75%, while the number for protein will be around 50%. In the end, meat may contain more fat than protein, sometimes substantially more. Meat and protein are not the same. Just imagine what happens when you deep-fry meat, then!

Does fatty meat taste better? Meat lovers will tell you that they like their meat marbled. Here are a few interesting facts. The flesh of young animals contains more water than older animals, from an intra-species point of view. Of course, there is no point in comparing chickens and cows about this. But within the species, the rule applies, and so does the feeding program. An interesting detail about taste is that aromatic molecules are soluble in fat, but they are not soluble in water. Those aromatic compounds come from the food the animals eat. Therefore a fattier animal will contain more aromatic compounds than a leaner one, all things being equal further. Of course, the kind of feed they eat also contribute greatly. An animal that eats lots of bland feed will not have much of these compounds, even if it is rather fatty. And a less fatty animal that would eat lots of aromatic feed might taste better. When it comes to the marbling, aromatic compounds are not the only thing that plays a role. Marbled meat will keep its juiciness better and will have a softer texture than a lean meat. Lean meat contains relatively more water that will evaporate to some extent during the cooking and  as water leaves the meat fibers, the meat might end up a bit stringy, especially if it is cooked through and though.

Related imageDo you see now why a Pata Negra pig’s ham tastes so good? It is a pig that is kept in semi-wilderness in Spain and feeds for several years eating chestnuts and other shrubs in a region where vegetation is sparse. It is quite different from a pig that is fed intensively and slaughtered at 6 months of age or so. The price is not the same, either.

So there you have it, fat is good but you must make sure it is good fat and that you eat with moderation. In the end what you have on your plate is a compromise between many contradictory requirements such as taste, quality, cost and price.

Carbohydrates are diverse

Carbohydrates have been under scrutiny for a while, in particular since the Atkins diet became popular. Are carbohydrates bad? If the answer is simple in popular media, the reality is, as usual, a bit more complex.

First of all, it is important to realize that carbohydrates are not a homogeneous group of nutrients. They can be divided in three categories: fast carbs, slow carbs and fibre.

Fast carbs are called that way because they pass into the blood stream quickly after being ingested, and provide 4 calories per gram. They are small molecules. They are commonly known as sugars and the most common ones are glucose, fructose (a typical carb from fruit as the name indicates) and sucrose (the powder sugar you find in stores). Sucrose is a combination of one molecule of glucose with one molecule of fructose. The purpose of fast carbs in the body is to provide energy quickly, in particular to provide the brain with glucose, as it is the only fuel the brain can use to function. For as much as they are very useful for a quick energy boost, they will be metabolised and stored as body fat if the body cannot burn the quantity sent in the blood stream. This latter characteristic is important to understand from a nutritional point of view. Do not eat more sugar than you can burn in the short term because it will go to your hips. They are useful during intense exercise. Professional cyclists often use glucose from their bottle. Here is a little calculation to show how it works:

Since fast carbs should be 40% of total carbs maximum and carbs should be 60% max of total calories, the maximum amount of calories you can have from fast carbs is 40% x 60% = 24% of total calories. For a person who needs 2,000 calories per day, the maximum of fast carbs would be 24% x 2,000 = 480 calories. Apples and oranges are about 50 calories per 100g, carrots about 40 and bananas above 80. Let’s say you have 500 g of fruits and veggies per day. This would roughly amount to 5 x 50 = 250 calories. As you can see, with a few fruits and vegetables you get all the fast carbs that you need. Remember, 40% of 60% is the maximum. It is better to get fewer calories than this from fast carbs. But if you want a juice or a soft drink, how much could you have? If the total calories from fast carbs is 480 and you got already 250 from fruits and vegetables, there is room for only 480 – 250 = 230 calories. Since 1 gram of carb provides 4 calories, that would a maximum of 230/4 = 57.5 grams of fast carb per day. If you take a drink at 10% sugar, the maximum quantity of liquid is then 57.5/10% = 0.575 litre. If the drink contains 15% sugar, the number becomes 57.5/15% = 0.383 litre.

Slow carbs are quite different. The typical slow carb is starch, which can be found in grains (wheat, corn, barley, rice, etc…), pasta, potatoes and many legumes (beans, peas, lentils, etc…). They do not pass into the blood stream right away. Starch is a long chain that consists of glucose molecules. During digestion, and with intervention with insulin, starch is metabolized into a shorter chain, called glycogen, which is stored in the liver. As its name indicates glycogen is a word that means glucose-forming substance. Depending on the sugar level in the blood (aka glycaemia), the glycogen in released “on demand” with help of insulin to provide the organism with the needed glucose but just in the right quantity at the right time. This has two advantages. One is that glucose is not provided in one shot, as it would be metabolised and stored as body fat. Glucose is released just to be burnt. It is almost comparable with a high-efficiency furnace. The other one is that through this system, the carbs eaten during the meal will provide energy for a couple of hours at least, depending on the level of physical activity. Then, it is not a surprise that hunger happens around 11:00 am so about 3-4 hours after a breakfast with an appropriate amount of slow carbs. There is no need for snacking between meals if the meals are proper. Slow carbs also provide 4 calories per gram.

A small word is useful about gluten. The word starts with “glu” and is a normal component of grains, but on the contrary to what many people seem to think, gluten is not a carbohydrate. It is a protein. Gluten gives bread its network structure.

Fibres have a rather different function. The main form of fibre is cellulose, which is also a long chain of glucose molecules, but arranged differently than in starch. Cellulose is not providing energy as such, as it cannot be metabolised in the body. Fibres play the role of ballast. They help dilute the calorie density of foods (think of fruit and vegetables) and they probably also play a role in the clearing of the intestine during transit. Fibres may also play a role in reducing the risk of colon cancer.

As you can see, carbohydrates are useful, but they must be part of a balanced diet. Because of their characteristics, one should not splurge on fast carbs, because the excess quantity will be metabolised into body fat. A good guideline is to have no more than 60% of the total calories of the diet from carbs, fast and slow combined. The percentage of calories coming from fast carbs should be less than 40% of the total carbs calories, and less is even better. If you eat fruit regularly, you probably will have enough fast carb. It is better not to add sugar in tea, coffee or yoghurt to name a few, even though sweet tastes nicer for many people. Also pay attention of how much fast carb you have in the foods and beverages you buy. Soft drinks, juices and drink yoghurt can contain between 10 and 20% fast carbs. The best drink really is water (zero calorie).

Slow carbs are a bit less of a problem, because of the gradual release of glucose from glycogen. That said, a proper diet is a diet that just covers the needs of the body, and excessive consumption will inevitably lead to more body fat.

To sum up, carbohydrates are OK as long as consumed in a balanced diet. Too much carbs is bad, and so are too much fast carbs and too much slow carbs. The same is true with all groups of nutrients. Fat is fine but too much fat is not, and the same applies for protein as well.

A weekly menu at a French school canteen

It is interesting to see what French kids have on the menu at their schools. Here is a link that will show you the weekly menu in a random school somewhere in France. You can click on translate to see the page in English. The translation is reasonably good.

https://www.courrierdelouest.fr/actualite/saint-macaire-en-mauges-menus-du-restaurant-scolaire-municipal-jean-moulin-09-03-2019-391124

As you can see, every day’s menu is, it at least a three-course menu. It shows variety and it is rather well-balanced. As a side note, it is also interesting to know that meals are free, as schools are in France, as they are the school of the French Republic. No lunch money needed.

 

How much do people know about nutrition?

Here is a simple fun little exercise. Go ask your relatives, friends, neighbours or colleagues basic questions about nutrition. It is an eye opener.

Here is a list of 10 questions. The first one usually gets a reasonable rate of good answers. From there, it tends to go downhill.

  1. How many calories does a person need per day?
  2. How many grams of protein, fats and carbs does a person need per day?
  3. How many calories are there respectively in 1 gram of carbs, 1 gram of fat and 1 gram of protein?
  4. What percentage of the total calories should come from slow carbs, fast carbs, fat and protein?
  5. What are amino acids?
  6. What are essential amino acids, and how many are there?
  7. What are fatty acids?
  8. What are essential fatty acids?
  9. What is glycogen?
  10. What is insulin?

These are fairly basic questions about nutrition and the items listed play essential roles in or physiology and metabolism, and therefore in our health. Do not feel bad if you do not know all the answers because most people are like you. Even people who are involved in the food and agriculture sectors will stumble on those questions. A reason for this is simply that we do not at food as nutrition but we think of food much more in emotional terms than in rational terms. Our eating patterns are determined rather early in our lives and like many other things in life, we do not take a critical look at what we do but we just follow the pattern. Even serious health problems are not always enough to change our eating habits (what? give up bacon? You must be kidding me? -kind of reaction).

Just as an example, a few days ago I found an article from a significant US food company claiming that “children’s palletes are more adventurous nowadays”, referring to their finding that children are more interested in tasting dishes from exotic ethnic recipes. What on Earth has a palette anything to do with food? The proper word is palate. By the way, a palette is a range of colors. It is also the board that artists use to hold and mix paint.

When I read stuff like that, I am a bit worried. Remember my paragraph about the Gourmet impostors in my previous article? Here is a typical example of that, a company that wants to sound sophisticated by trying to use some fancy word that they do not even know.

I have worked many years in the agribusiness and the philosophy still is to push people to consume more of their stuff, not to educate them to build balanced meals unfortunately. My advice is: just learn about nutrition so that you know more than the food producers, and that should not take too long.

Lifestyles have changed but our biology has not

By the end of the 19th century, the Industrial Revolution brought many changes in the relation between humans and nature, and between humans and their nature. The changes continued and amplified after World War II with the rise of the so-called consumption society in developed countries. I say so-called because the economic model is not so much about consumption as it is about buying more goods all the time, while consuming them is secondary. In my opinion, the consumption society should be called the shopping society, as the latter term would describe its purpose more accurately.

The change of economic model has been accompanied with changes of lifestyle, both at home as at work. The level of physical activity has dropped in many jobs and now a lot of workers spend hours daily sitting. With TV and computers, the same trend has happened at home, especially with more and more housing units in urban centers without yards. Even though, many people try to practice some physical activity, there is a sharp contrast with life as it used to be. Nothing is perfect and progress also has its shortcomings.

If our societies have evolved amazingly quickly over the past several decades, our biology has not. Our metabolism, our physiology and our biochemistry are very much the same as they were tens of thousands of years ago, even as before agriculture appeared in human societies. The contrasts with today are many.

By then, food was scarce and humans had to travel long distances and put a lot of physical activity to find something to eat. Today, food is plentiful and all it takes is to sit in your car to drive to the supermarket, which involved little physical exercise, and with online deliveries, the physical activity is even reduced to zero. The former hunter will now turn into a larva.

By then, there would be days without food and if the human organism could survive, it is because it has the ability to store reserves in the body from times of abundance to be used when the hunters and gatherers would come back empty-handed. Today, many people do not even know hunger at all. The easy availability of food exceeds the nutritional needs and what is eaten but not burnt ends up being metabolised into body fat. The old biology does what it is supposed to do, as one of its key roles is to deal with periods of food shortages. In the developed world, people consume on average about twice as many calories, twice as much protein and fats as they actually need. Since that is on average, you can imagine the multiple for some people! The excess portion does not disappear. It is transformed into fat reserves. I like to say that if you eat twice as much as you should, it should not be a surprise to end up twice as big as you should be. Joke aside, it is actually a good thing that animals store food reserves as fat and not as starch as plants do. Reason for that is the calorie density of starch versus fat: 4 calories per gram for starch versus 9 calories per gram of fat. In other words, if you have an excess weight of 10 pounds, it would be 22.5 pounds of starch, so more than twice the burden. Plants do not move, so it is not much of an impediment, but if you need to run away from a predator, an additional 12.5 pounds would make you an even easier prey.

Another difference between modern foods and the old biology is that our bodies have evolved to eat what I would call primary foods; some might want to call them primitive foods even. My point is that our biology is actually rather effective in extracting nutrients from rough foods. A side effect of processing foods is that it makes nutrients more easily accessible, because the processing often breaks physical barriers to the nutrients. As the nutrients are easier to access and our biology is eager to get them, it is only logical that processed foods are metabolised differently and faster than primary foods, thus in fact increasing their nutritional density, which results in more excess nutrients ready to be sent to the fat tissue.

A lot of the issues about the skyrocketing statistics of obesity, overweight, diabetes, cardiovascular diseases and other food-related ailments find their origin in the fact that our lifestyles have changed while our biology has not. Food availability has changed. Foods have changed. Agricultural methods have changed. Economic models have changed. Diets have changed. Level of physical activity has changed. They all contribute to an imbalance between consumption and needs, which results to food-related problems. This is why, it is more important than ever to make education about food, agriculture and nutrition mandatory in schools. If we consider that education is the basis for better lives, then there is no argument why these topics should not be life basics for all children and adults alike!

Also considering the cost of health issues related to food, I bet you that education about food, agriculture and nutrition would pay off for individuals, insurance companies and governments alike.

The Locavore’s Dilemma

Here is a third popular article from my Food Futurist website, that is actually used in schools curriculum in the USA:

There is a growing trend, or at least a growing noise in favour of eating locally produced food. The “locavores” as they are called, claim that 100-mile food is the way to a more sustainable agriculture and consumption. Is this approach realistic and could it be the model for the future?

This movement is rather popular here in Vancouver, British Columbia. The laid-back residents who support the local food paradigm certainly love their cup of coffee and their beer. Wait a minute! There is no coffee plantation anywhere around here. There is not much barley produced around Vancouver, either. Life should be possible without these two beverages, should not it? The disappearance of coffee –and tea- from our households will make the lack of sugar beets less painful. This is good because sugar beets are not produced in the region. At least, there is no shortage of water.

But this is not all. There is no cocoa plantation around here, and believe me, there are many people who are addicted to chocolate. British Columbia does not produce citrus or other warm climate fruit. If we are to become locavores, we must say goodbye to orange juice, to lemons, to bananas. Even the so popular sushi must disappear because of the lack of rice. There are no rice fields in this area, and neither are there wheat fields. The Asian population certainly would have a hard time eliminating rice from their diet. The lack of wheat means no flour; and no flour means no bread, no pastries, and no cookies. The carbohydrate supply is going to be tough. If we must consume local, our lifestyle is going to change dramatically. Potatoes and cabbage is the way of the future. But before going all local food, the local locavores must realize that British Columbia produces only 48% of all the food its inhabitants consume. One out of two locavores would have to starve. Going exclusively local would also affect deeply the source of animal protein. Most of the animal feed is made of ingredients that come for much farther than 100 miles. The chickens and eggs would become less available. Farmed salmon, BC’s largest agricultural export could not use the type of feed they currently use, as fishmeal and fish oil come from Peru and vegetal oil comes from farms located far away. There would go many jobs with very little alternatives. If we look beyond food, other agricultural products such as cotton and wool would not be an option anymore. Cars would disappear, because the main component of tires, rubber, is not produced under this climate. The 100-mile rule will solve traffic problems. If local consumption is the rule for food, should not it be the rule for everything as well? China would probably have different views about this. Not only would their manufacturing collapse, but also if they have to produce food within 100 miles of the consumer, they would have to give up importing agricultural commodities. For them, a true locavore system would mean famine. The same would be true here in British Columbia. When people are hungry, they are not so picky about the distance from the producing farm.

The problem with concepts such as local consumption is that the basic idea has some value, but the idea quickly evolves into an ideology, and ideologies tend to make their followers stop thinking pragmatically. Today, the idea of eating locally in a place like Vancouver is possible because supply easily meets demand, thanks to the 3,000-mile foods. This is ironical. If the distance to market has to be within 100 miles, farmers in low population density areas, such as many regions of North America, South America and Central Europe, would have a different type of problem. They would produce an abundance of food, but because there are not enough people to consume it locally, the law of supply and demand tells us that the price of agricultural commodities would plummet, food would stay in storage and farmers would go out of business, while people in China, and in British Columbia, would suffer hunger. Clearly, the 100-mile diet needs some amendments.

Intuitively, it sounds logical that locally produced food has a lower carbon footprint than food that comes from 2,000 to 10,000 miles away. However, this is only partly true. The mean of transportation affects the carbon footprint. The environmental impact of transport is much higher for road transport than it is for rail transport, which is also higher than water transport. The type of transport also depends on the type of commodity brought to market. Perishables need to reach consumers as quickly as possible for shelf life reasons, while dry goods, such as for instance grains and oilseeds do not face the same kind of deadline. The quality of the logistics is also crucial to reduce the carbon footprint. A fully loaded truck is much more efficient than a local truck dropping small quantities in many places, thus driving around most of the time with empty space in the trailer.

The emphasis should not be so much on local as it should be about the search for efficient and low environmental impact. More than the distance from the farm to the consumer, it would be more useful to provide consumers with information about the actual carbon footprint of the products they buy. They would have the possibility to make the right choices. Retailers, too, would be able to make decisions about their sourcing strategies. Clean products and clean producers need to be rewarded for doing a good job. Here in Vancouver, local food products are more expensive than similar offerings from California, Mexico, Ecuador or Chile. How do you convince families with a tight budget to spend more for local products that look pretty much the same? This problem needs to be addressed. Currently, farmers markets are much about marketing. They sell the experience as much as their production methods. Only a wealthy minority can afford to buy on these markets. The prices are not based on production costs plus farmers income. They are as high as possible, because the farmers can ask these prices. The wealthy city dwellers are willing to pay a substantial premium above what they can buy from the local supermarket. In this relation farmer-consumer, the price bargaining does not take place. If these farmers were to try to sell to a grocery retail chain, they would never get the prices they get from the consumers who will not haggle about the price. This is why more farmers try to sell directly to consumers: they make more money that way. However, this might change in the future. A number of retailers are working towards offering “farmers market” products into their store. This already makes market farmers nervous.

Is local production for local markets the way of the future? My answer is that it partly will be and it partly will not. I do expect a shift of the location of production for perishables. Consumer habits will change, too. In the West, consumers have been spoiled. They can eat anything from anywhere at any time of the year. This luxury probably will not be affordable for long anymore. The superfluous will naturally be eliminated.

As the economics of energy, and therefore of food, will change, producers will increasingly locate their operations closer to cities; and even inside cities. Urban farming is a growing activity. Although it started mostly in poor neighbourhoods as a way of having a small patch of land for personal consumption, more sophisticated and efficient systems are being developed. My expectation is that production, and consumption, of vegetables and fragile fruit (for instance strawberries) will gradually become more integrated in the urban landscape than they are now. I also think that we will see animal productions, such as fresh dairy, poultry meat and eggs relocate closer to consumer markets. An interesting development is aquaponics, the combination of greenhouse produce with fish production in tanks. The production of non-perishables will not relocate. It does not have to. What will probably change is the transportation infrastructure in many areas where these commodities are produced.  This is good news for coffee drinkers and chocolate addicts. After all, transport of commodities over long distance is not just the result of cheap oil. The Silk Road and the spice trade by the Dutch took place before mankind even knew about oil. Trade has always been a force of progress for humanity. It helps an increasing number of people to have access to goods that make their lives better. The rules of trade may not always be fair, but like all human activities, it is a work in progress. Limiting our food supply to 100 miles would be a regression. Subsistence agriculture has not demonstrated that it could feed the world. Most of the people suffering of hunger live in subsistence agriculture areas.

Nutrition basics should be taught in school

Here is one of the articles (from 2009) from my other website, The Food Futurist, that motivated me to create this website:

When food costs twice!

A recent report showed that the annual medical cost of obesity reached $147 billion (see article). On the other hand the contribution of the meat and poultry industry in the US is $832 billion annually. Therefore, we can expect ongoing arguments between economic interest and health care costs for a while. The simple fact is that too many Americans do not eat a properly balanced diet and that should change.

The most efficient way to improve eating habits is by understanding nutrition and educating children at an early age about health and food, and about diseases caused by either unbalance or excess. Food safety is not only about bacteria or residues, but also about handling food properly and eating right.

People know actually very little about proper nutrition. The average person may have some ideas about how many calories he/she needs on a daily basis, but it hardly goes much further than that. Only few people know how many grams of protein they should consume on a daily basis. They know even less how many grams of fat they need. When it comes to carbohydrates, the situation is just as confused and confusing. Most people do not even know how the different groups of carbs (starch, sugars and fibers) are metabolised and what ratio between them they should consume. The result is a diet that has negative long-term effects.

If the FAO estimates the daily calorie needs at 1,800 for an average human being, the averages in developed countries are much higher, reaching about 3,500 on average for Western countries and even 3,800 in the US. The same conclusion is true for protein and other nutritional elements. It should be no surprise then that when people eat twice as much as they should, they get twice as big as they should, too. The reality is that in developed countries, people do not eat what they need, but they eat what they want. And they want too much.

Balanced nutrition is not difficult to understand, but someone needs to teach it. As parents have about as little knowledge and understanding as their kids do, schools would be quite well inspired to put nutrition on their curriculum. After all, schools are the places where future generations are educated to do the right things in the future, or at least it should be part of their mandate. Helping people eating right is part of creating healthy and prosperous societies. Sick societies will not be leaders. Of course, including nutrition in the curriculum is not enough for schools. They must also provide foods and drinks that contribute to healthy eating. Offering kids access to junk foods and junk drinks in vending machines may generate revenue for schools, but it works against helping kids to have a healthy diet. If they have the choice, kids will not spend their lunch money on water and broccoli. The responsible adults in charge must help them make the right choices. Offering treats is not to schools to decide, but only to the parents.
