In the early 20th century the discovery of vitamins began. Today there
is a chance that there are some vitamins that are still undiscovered. The
definition of vitamin is: one of several substances necessary for animal
nutrition, and occurring in minute quantities in natural foods; numerous types
have been distinguished, and designated by the letters of the alphabet. Each
and every living animal needs vitamins to grow and be healthy.
Since the human body can t produce vitamins naturally or normally
produce the amounts needed, food provides the body with them. There are
different vitamins found in different foods. These vitamins give vital
nutrients to an animal.
In 1906, the...

With Americans taking more vitamin supplements than ever, there becomes less distinction of the fine line between what is healthy and what is not. Forty percent of theUnited State's adults spend almost two billion dollars on pills containing vitamins and minerals, but many are not helping their bodies - in fact, they may be hurting them. The supplements are often used as a "quick-fix" or replacement for real healthy living. As a result, people are very commonly putting too much, too little, or even not the correct vitamins into their body. So what are the right vitamins? What is too much, and what is too little? The guidelines vary from person to person, dependent on such...

A person eats to gain energy from food that allows our body to perform various functions that allows us to survive. The food that people take in will go through their digestive system that then allows them to harness the energy within food. That energy that is taken from the food is then sent, via the bloodstream, to all of the living cells. These cells then use this energy to perform their daily functions and tasks. We also eat food to help rebuild and repair damaged and old cells.
Diets are particular foods that are eaten by a particular person or group. There are many types of diets that can either differ in small ways or big ways. Different diets can also be healthy or unhealthy...

People enjoy eating delicious food because they want to get essential nutrition from them. Who can resist a quick burger and fries when time is of the essence? But do you know what you're eating? For example, do you know how many calories are in a Taco Bell Gordita? Have you ever considered how much sodium you're consuming with an Arby's Bac'n Cheddar Deluxe? The numbers just might surprise you -- some for the better, but others for the worse.1. Influences on Food ChoicesFood choices are influenced by many factors, age, gender, friends, family, cultural background and where we live. Although the main purpose of food is to nourish the body, food means far more than that to many people. It can...

It is no coincidence that well fed dogs are usually the happiest and healthiest dogs. Just like people, dogs need to eat a well balanced diet to maintain their health and live long, active lives. Dog nutrition is very similar to human nutrition, but dogs are not people. They are unique animals with dietary needs based on centuries of evolution. While dogs are more omnivorous than pure carnivores like cats, they are not true omnivores like human beings. They evolved from wolves, so they tend to do best on meat based diets.
Important nutrients to consider when planning a dog’s diet include water, proteins, fats, carbohydrates, vitamins and minerals. Often overlooked, water is a...

Nobody expects a machine to run without fuel and that requires a specific kind of fuel, one that the machine was created to run on. Unlike those machines, our bodies require certain types of food as fuel and it seems that more often than not we fill our bodies with the wrong foods. It is crazy to think that we expect our bodies to function properly when we do not treat them properly. Eating is one of the most important and...

Definition of Nutrition:Nutrition is the study of the materials that nourish an organism and of the manner in which the separate components are used for maintenance, repair, growth, and reproduction. Nutrition is achieved in various ways by different forms of life. Plants that contain the green pigment chlorophyll can synthesize their food from inorganic substances in the process called photosynthesis. Organisms such as plants that can thus manufacture complex organic compounds from simple inorganic nutrients are termed autotrophic. Organisms that must obtain "prefabricated" organic compounds from their environment are heterotrophic, and these include the fungi, some other plants, and...

Testing Food Substances for the Presence of LipidsAim:To establish which food substances contain lipids.Hypothesis:1. All diary products will contain lipids.2. All animal tissue will contain lipids.3. All plant storage organ products, i.e. seeds, will contain lipids.Introduction:Lipids are insoluble in water but soluble in organic solvents. Ethanol is an example of an organic polar solvent which will dissolve lipids to a limited extent. However ethanol is miscible with water so when a solution of lipid and ethanol is added to water the ethanol will combine preferentially to the water, leaving the ethanol to form tiny globules in the water. These globules then form a white emulsion.Sudan III...

What is nutrition? Why is nutrition important? Nutrition, nourishment, or aliment, is the supply of materials - food - required by organisms and cells to stay alive. In science and human medicine, nutrition is the science or practice of consuming and utilizing foods (MNT, 2014). A nutrient is a source of nourishment, an ingredient in a food, e.g. protein, carbohydrate, fat, vitamin, mineral, fiber and water. Macronutrients are nutrients we need in relatively large quantities. Micronutrients are nutrients we need in relatively small quantities (MNT, 2014). The six common substances that are known to be essential for the human body to function properly are carbohydrates, lipids, proteins,...

Many people are confused about the difference between soap and detergent. Soaps and detergents are not the same thing, although both are surfactants, or surface active agents, which basically means a washing compound that mixes with grease and water. Soaps are made of materials found in nature. Detergents are synthetic (although some of the ingredients are natural); they were developed during World War II when oils to make soap were scarce. There is little doubt that soap is better for your health and the environment than detergents. Detergents are very toxic to fish and wildlife. Nonetheless, a big drawback of washing with soap is that the minerals in water react with those in soap, leaving...

People say that the three most important things we humans need in order to survive are food, clothing, and shelter. I think out of those three things most people would say that food is the most important thing because that is what keeps us alive. Sure clothing and shelter will keeps us nice and warm, but we don't really need it to survive. Before humans started to settle down and build shelter in order to live in one place, they used to be nomads. Nomads would wander on the Earth with no real shelter except for what Mother Nature gave them. In order to survive, these nomads would have to hunt and gather their own food. If they could not get enough food or water to make it through the day...

The Effect of Food on Humans
''You are what you eat.'' The food we consume determines our
physical and psychological health. The muscles in the body, and the
blood flowing through the veins, are all supplied by the food that we
consume. These foods also have an effect on the way the brain
functions, and an effect on the body's performance. People might say
they are hungry and genuinely believe it when in fact they are feeling
sad. This is due to the lack of neuro- chemicals in the brain which
carry messages and control nerve impulses. When the right types of
food are eaten, the neuro- chemicals contained in the foods enhances

My personal health goal is to eat healthier foods and consume less junk food. As a runner, I realize that this is very important for me if I wish to achieve maximum results. In considering where to look for advice on good food choices, I decided that the best place to look would be in Runner's World Magazine. Sure enough, in the January 2001 issue I found an article titled Kitchen Think. The article gave helpful advice for my goal. The first thing mentioned was that fat should be an important aspect of every runner's diet. It is something that cannot be left out, but should be properly balanced. Only 30-35% of total calories should come from fat, which does not mean a ton of sugary...

The Biological Importance of WaterWater is a simple molecule, made of hydrogen atoms and oxygen atoms in the ratio of 2:1, yet it is fundamental to life. In active living cells, two-thirds, or often more, of the area is occupied by water, and two-thirds of the globe is covered in water. Water is therefore extremely abundant, and in biological terms it has great importance both inside cells, and externally, for example as a habitat. Water is the most abundant component of any organism. Humans are 60% water, and most organisms are 60-90% water. The water is found mainly in the protoplasm, and here it plays vital roles in many functions, for example in metabolism in all organisms, and...

They also have higher Lysine and Iron content which is of special benefit to anemic persons, which helps to improve the Hemoglobin level of their blood. Whole soybeans contain about 34 percent of total carbohydrates on a dry weight basis. This fraction is devoid of starch, and therefore, has less nutritional significance than protein and oil. The carbohydrates mat is divided into the soluble and insoluble fractions. The soluble fraction, consisting of about 10 percent of the total carbohydrates, includes primarily the...

Many Americans can tell you what components make up their food. Looking at a nutrition facts label, they can tell you the content of fat, carbohydrate, and protein in the foods they eat. Many participate in low carbohydrate dieting, one of the most popular diets around. Others have opted for the United States Department of Agriculture's low fat diet, but neither understands the chemistry of the body or may have misinformation about these compounds. Not many Americans can tell you confidently what a fat, carbohydrate, or protein is chemically or how it works in the body. It can be confusing for the 65% of United States adults who are considered obese and everyone else to figure out what...

Most of the people consider eating as a process connected to giving themselves a kind of pleasure, others associate it with a way of survival or simply take it for granted, accept it as a given part of their lives without questioning themselves about the real purpose of this "ritual" as we can call it. In fact, why do we have to bother our lifestyle with so complicated, as some may say, questions or issues? The answer is: because it is not just for our entertainment, people have to be aware that our health is a consequence from the food we consume; the way we combine different essential kinds of food may be crucial and sometimes result in irreversible diseases and effects.

Abstract— Fluoride (F) is an essential element for life. At low concentrations, it is generally believed that fluoride deficiencies can arise, but at high fluoride concentrations other deleterious effects can certainly transpire. This study was conducted to evaluate F content and its spatial variability in Isfahan province. This area covers different land uses including agricultural, industrial, urban and uncultivated lands. Two hundred and fifty five topsoil samples (0- 20 cm) in a study area of 6800 km² were collected. Total fluoride and water soluble fluoride were measured. The results of this research showed that two forms of soil F were controlled by intrinsic factors such as parent...

Chromium, the seventh most abundant element on earth is a transition metal from group VI-B .It is found in nature as the bound form constituting approximately 0.1 – 0.3 mg.g-1 of the earth’s crust. The name of the element is derived from the Greek word "chroma" meaning color, because many of its compounds are intensely colored. Cr is able to exist in several oxidation states, of which the trivalent Cr (III) and hexavalent Cr (VI) species are the most stable and abundant forms (Zayed & Terry et al., 2003).
The most stable form of chromium is its trivalent oxidation state which is primarily found geologically as chromite (FeCr2O4) (Cervantes et al., 2001). Cr (III) is naturally occurring,...

Has mankind discovered some fantastic substitute for fat to enable people to eat as many snacks as possible without gaining weight? Recently, Proctor & Gamble developed Olestra (sucrose polyester), a zero calorie fat-based substitute, at a cost of $200 million. This product has been approved by the Federal Drug Administration (FDA) with warning labels.
What is olestra?
The olestra molecule differs from a fat molecule in that it has six to eight fatty acids on a sucrose core, as opposed to three fatty acids on a glycerol core. The bulkier olestra molecule is not digested, absorbed , or metabolized, and thus provides no calories” (Stern & Hermann-Zaidins...

One of the most controversial foods consumed is meat. In general, there are two extremes associated with meat; those who over consume and those who chose not to eat meat at all. Of course there are concerns associated with over consumption of meat such as cancer, cardiovascular disease, high blood pressure, and metabolic syndromes. Also, diets high in meat have high protein content so those individuals will sometimes not receive enough energy from carbohydrates, ultimately putting strain on the kidneys, leading to dehydration and ketosis (Wyness, et al., p. 35).
When considering negative effects of meat consumption, the main focus is weight management, cholesterol, cancer, and coronary...
