Health: Nutrition and health 1

Nutrition and health 1
"If we can change the way people eat, we let the children know their parents a little more" (Neal Barnard)

Overview and History:

Human’s omnivores able to consume both plant and animal products We have adopted a number of diets that vary with available food sources in regions where we live and also with the cultural and religious norms, these range from purely vegetarian to the mainly carnivorous.
In some cases, restrictions in the diet can lead to nutritional disorder, however, we have adapted to many dietary patterns and dieting prominently reflected in human culture, and has led to the development of technology foods.
Diet varied significantly depending on location and climate, so that the diet in the tropics tended to be based more heavily on plant foods, while the diet at higher latitudes tended more towards animal products.
Taking a look from antiquity to 1900 we find that the first nutrition experiment is recorded in the Book of Daniel in the Bible.
 Daniel and his friends were captured by the king of Babylon during an invasion of Israel. Selected as court servants, they should eat fine food and wine for the king Nebuchadnezzar But they objected, preferring vegetables and water in accordance with their Jewish dietary restrictions. The king's steward reluctantly agreed to a test. Daniel and his friends received their diet for 10 days and were then compared to the king's men. As appeared healthier, they were allowed to continue their diet.
Hippocrates is considered the father of medicine. We cannot say certainly that was a sick person as this is not stated in the story, but we know who lived to be 107 years was born on the island of Cos 460 years before Christ. Book to Athens of the plague.
His authority is recognized by figures such as Plato, Socrates and Aristotle, by powerful kings like Artajerjes and Alexander, and the most varied talents that produced the Age of Pericles.
The main reform was to change the vulgar in their time attributed to the gods the phenomena that occur in the human body, showing that biological phenomena are subject natural and permanent laws. He claimed that nature is healing and that there are no diseases but only sick.
To 475. C., Anaxagoras stated that the food is absorbed by the human body and therefore contained "homeomerĂ­as" (generating components), suggesting the existence of nutrients.
In the sixteenth century, scientist and artist Leonardo da Vinci compared metabolism to a burning candle.
 In 1747, Dr. James Lind, a physician in the British navy, performed the first scientific nutrition experiment, discovering that lime juice prevented the sailors with many years of sailing scurvy sick of a deadly and painful bleeding disorder.
 The discovery was ignored for forty years, but after that the British sailors they became known as "limes." What is essential in the lemon juice (vitamin C) would not be identified by scientists until the 1930s.
Around 1770, Antoine Lavoisier, the "Father of Nutrition and Chemistry" discovered the details of metabolism, demonstrating that the oxidation of food is the source of body heat.
In 1790, George Fordyce recognized calcium necessary for the survival of poultry.
In early 1800, the elements carbon, nitrogen, hydrogen and oxygen were recognized as the main food components and developed methods to measure their proportions.
In 1816, Francois Magendie discovered that when dogs are fed only carbohydrates and fats, proteins and loses body dies in a couple of weeks, however, dogs fed protein also survive. In this way the proteins identified as an essential component to the diet.
In 1840, Justus Liebig discovered the chemical makeup of carbohydrates (sugars), fats (fatty acids) and proteins (amino acids)
 In the 1860s, Claude Bernard discovered that body fat can be synthesized from carbohydrate and protein, showing that the energy in blood glucose can be stored as fat or as glycogen.
In the 1880s, Kanehiro Takaki observed that Japanese sailors (whose diets consisted almost exclusively of white rice) developed beriberi (or endemic neuritis, a disease causing heart problems and paralysis), but British sailors and naval officers Japanese did not. The addition of various types of vegetables and meats to the diets of Japanese sailors prevented the disease.
In 1896, Baumann found iodine in the thyroid.
In 1897, Christian Eijkman worked with natives of Java, who also suffered from beriberi. Eijkman observed that chickens fed a diet of white rice developed the symptoms of beriberi, but remained healthy when fed rice, which includes the outer layer of rice. Eijkman cured the natives by feeding them brown rice, discovering that food can cure disease. Over two decades later, nutritionists discovered that the outer shell or rice contains vitamin B1, also known as thiamin.
As early as 2400 years ago, was known relationship between diet and health: Hippocrates said that our food was our medicine. It is well known that dietary factors are associated with diseases such as diabetes, osteoporosis, overweight, obesity, hypertension, heart attack, stroke, some cancers and others.
The intake of too many saturated fatty acids and cholesterol can cause atherosclerosis. In contrast, in the twentieth century demonstrated the link between food shortages and serious diseases. These different forms of malnutrition are still, even now, public health problems.

Review some general concepts of the biochemical composition of structural and functional components of our body, and then jump to the topic of this article.
Carbohydrates, proteins and fats provide 90% of the dry weight of the diet and 100% of its energy. All three provide the energy (measured in calories), but the amount of energy per gram is different: 4 calories per gram for carbohydrates or proteins, and 9 calories per gram of fat. These nutrients also differ in the rate at which energy is consumed. Carbohydrates are the fastest, while fats are the slowest.
Carbohydrates, proteins and fats are digested in the intestine where it is decomposed into their basic units the carbohydrate sugars, amino acids proteins, and fats into fatty acids and glycerol. The body uses these basic units to build substances it needs for growth, maintenance and activity (including other carbohydrates,
 proteins and fats).

Depending on the size of the molecule, carbohydrates may be simple or complex.
Simple carbohydrates: Sugar in various ways, such as glucose and sucrose, are simple carbohydrates. They are small molecules, so they can be broken down and absorbed by the body quickly and is the fastest source of energy rapidly increasing blood glucose (blood sugar).
Complex carbohydrates: Carbohydrates are composed of long chains of simple carbohydrates. Are called complex carbohydrates that are larger than molecules of simple carbohydrates and must be broken down into simple carbohydrates before they can be absorbed. Therefore, they tend to provide energy for the body more slowly than simple carbohydrates, but still faster than protein or fat. Because they are digested more slowly than simple carbohydrates, are less likely to be converted into fat. They also increase the levels of blood sugar more slowly and reduce levels of simple carbohydrates, but for a longer time. Complex carbohydrates include starch and fiber, which are obtained from wheat products such as bread and pasta, in other grains such as rye and corn, beans and root vegetables such as potatoes.
Carbohydrates can be refined or unrefined. Refined means that the food has to be greatly transformed. The fiber and bran contain as well as many vitamins and minerals. Thus, the body processes carbohydrates rapidly and provide little nutrition despite containing approximately the same amount of calories. Refined products are often enriched; vitamins and minerals have been added to increase its nutritional value. A diet high in simple carbohydrates or refined tends to increase the risk of obesity and diabetes.
To consume more carbohydrate than they need at the time, the body stores some of these carbohydrates into cells (such as glycogen) and converts the remaining fat. Glycogen is a complex carbohydrate that the body can easily and quickly convert to energy. Glycogen is stored in the liver and muscles. Your muscles use glycogen for energy during periods of intense exercise. The amount of carbohydrates stored as glycogen can provide nearly a day's worth of calories. Some other body tissues to store carbohydrates as complex carbohydrates that cannot be used to provide power. The recommendation is that 50% to 55% of total daily calories should consist of carbohydrates.
Proteins consist of units called amino acids, linked together in complex formation. Because proteins are complex molecules, the body takes longer to process. As a result, a source of energy consumption slower and longer lasts than carbohydrates.
There are 23 different types of amino acids. The body synthesizes some of the components in the body, but can not synthesize 9 amino acids called essential amino acids. They must be consumed in the diet. Everyone needs eight of these amino acids: isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. Children also need, in addition to the above amino acid, histidine. The percentage of body proteins can be used to synthesize amino acids varies from protein to protein. The body can be used for example to 100% of egg protein and a high percentage of protein in the milk and meat.
The body needs protein to maintain and replace the tissues and to function and grow.
 If the body is getting enough calories, no need to use protein for energy. If you consume more protein needed, the body processes transforming proteins into energy.
The body contains large quantities of proteins. Proteins are the main element in the body and the principal component of most cells. For example, muscles, connective tissue and skin are all built of proteins.
Adults need to eat about 60 grams of protein per day (0.8 grams per kilogram body weight or 10% to 15% of total calories). Adults who are trying to increase muscle mass need a larger amount of protein. Children also need to take a lot of foods rich in protein to grow.

Fats are complex molecules composed of fatty acids and glycerol. The body needs fat for growth and for energy. Also used to synthesize hormones and other substances necessary for the organization's activities (such as prostaglandins). Fats are the energy source slower but more efficient, energetically, which can be found in food.
Each gram of fat in the body, delivers about 9 calories, more than double that provided by protein or carbohydrates. Since fats are an energy efficient way, the body stores the excess energy as fat. The body excess fat deposits in the abdomen fat) and under the skin (subcutaneous fat) waiting to be used when you need more energy. The body can also deposit excess fat in the blood vessels and organs, so it can block blood flow to the organs, often causing severe disruptions.

Proper nutrition
"There is science, not antibiotics, not machines or new equipment. It is the body and medicine, this is the real hero. "(Ronald Glasser)

Everyone is exposed to diseases. But not all body care as they should. Ignorance and mercantilist desire health officials are two reasons or reasons that hinder the achievement of good health. In Case ignorance are not exempt ourselves. In modern times, we are almost bombarded by massive industrial chemistry, which affects the quality of the resources of the earth, the air we breathe and the water we drink. No need to be very keen to see what detrimental given day is the quality of life. And the problem with this situation and becomes irreversible. But besides the drama of this situation is the great capacity we have to "adapt" these new forms of existence. And the inevitable result is an increase in diseases such as cancer and others. At the end depends on the individual search and access to adequate information to care for the body in the best way that we can. And the doctor happens to be one of the tools to help, but not the only one.
We always care about the cleanliness of our body, the house and the car, but we neglect to do with our organism, which makes no sense.
I had access to reading a great book by Dave Frahm entitled "Battle against Cancer: Resource Book". This book I "woke up" from my former knowledge in biology and current habits and today, my wife and I are implemented.
As social communicator I wanted to share with people some of what this book teaches to exercise proper nutrition to help the body to prevent and / or cure of many diseases.
The author says rightly that God designed the human body to be able to self protect and heal. Your body all the time moves forward protecting and repairing some damage. If you break a bone, the body immediately covers the affected area with more minerals to heal the damaged. If you are under attack by viruses, the body sends its police force (white blood cells) to arrest and take the intruder. However, in the body actually experienced a situation, and which had often unnoticed, that at least you have several thousand cancer cells floating in the blood stream.
 The reader of this note, myself and my neighbor or friend with cancer cells. Again we see the wonderful body sampling design. Since this force to go to meet the virus, is also designed to destroy mutant cells, we call cancer.

 The body we inhabit is like a super-mega-city of a hundred million trillion individuals working together as a team keeping the city running smoothly cell in order.
Billions are working on communications infrastructure that keep all interconnected with a control center in the brain. Other million work in purifying systems, production and storage plants and many millions in the learning centers.
The amazing thing is the job efficiently and without errors that keep alive our body.

But many wonder if my body is so great and wonderful and self protection, then why am I so sick?

The fundamental truth is that many of the degenerative diseases such as cancer, heart and circulatory system, stroke, diabetes, arthritis, fibromyalgia, chronic fatigue, osteoporosis, and others is because that we caused us, and mostly out of ignorance.

This article is an introduction only as learning to help the body to win a fight against any disease restoring a good balance synonymous with good health.
The author begins his explanation of the topic with a comparative history about which we should lighten our burdens of toxins, says a man driving through some mountains and a day stopping the vehicle began to load it with rocks, and were such that his car was very low due to the weight, He drove a little and stop to pick up a rock again, and suddenly heard a loud noise as the car's suspension broke.
Then the gas tank pit and caught fire in seconds. He and the car was reduced to ashes.
What could a man do to prevent self destruction and death?

This is the central question that emerges between good and poor health; between being healthy or sick. Common sense dictates that man should avoid loading more rocks.
 The relationship between cause and effect, the problems unleashed experiment.
Another obvious thing is that to fulfill its tendency to carry things should be better prepared to invest money in the suspension of your car.
 Our body is equal to that car. We all go through our lives accumulating many "rocks".
Our rock is stressful toxins that we give to the body, and that the body requires to function normally and stay healthy.

Unfortunately over our lives toxin load becomes excessive, and is where health drop occurs.
Our bodies fight hard and enact its defensive system, but good health is compromised, due to excess "rocks" with which we loaded our "car."

This article series will continue.
