Factory farming
1. Factory farming involves raising livestock in confinement at high stocking density, where a farm operates as a business – a practice typical in industrial farming by agribusinesses. The main products of this industry are meat, milk and eggs for human consumption. There have been issues regarding whether factory farming is sustainable and ethical.
2. Confinement at high stocking density is one part of a systematic effort to produce the highest output at the lowest cost by relying on economies of scale, modern machinery, biotechnology, and global trade. Confinement at high stocking density requires antibiotics and pesticides to mitigate the spread of disease and pestilence exacerbated by these crowded living conditions. In addition, antibiotics are used to stimulate livestock growth by killing intestinal bacteria.
3. There are differences in the way factory farming techniques are practiced around the world. There is a continuing debate over the benefits, risks and ethical questions of factory farming. The issues include the efficiency of food production; animal welfare; whether it is essential for feeding the growing global population; the environmental impact and the health risks.

A vitamin
1. A vitamin is an organic compound required by an organism as a vital nutrient in limited amounts. An organic chemical compound is called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from the diet.
2. Vitamins have diverse biochemical functions. Some have hormone-like functions as regulators of mineral metabolism (such as vitamin D), or regulators of cell and tissue growth and differentiation (such as some forms of vitamin A). Others function as antioxidants (e.g., vitamin E and sometimes vitamin C). The largest number of vitamins (such as B complex vitamins) functions as precursors for enzyme cofactors that help enzymes in their work as catalysts in metabolism.
3. Until the mid-1930s, when the first commercial yeast-extract vitamin B complex and semi-synthetic vitamin C supplement tablets were sold, vitamins were obtained solely through food intake, and changes in diet (which, for example, could occur during a particular growing season) usually greatly altered the types and amounts of vitamins ingested. However, vitamins have been produced as commodity chemicals and made widely available as inexpensive semisynthetic and synthetic-source multivitamin dietary and food supplements and additives, since the middle of the 20th century.

Biology of Psychiatric Disorders
1. Psychiatric disorders are a diverse group of brain disorders with symptoms that primarily involve emotion, higher cognitive function, and the ability to control complex behaviors.
2. The major psychiatric disorders are common and often run a chronic course. The chronic disorders include anxiety disorders, attention deficit hyperactivity disorder, autism, obsessive-compulsive disorder, and schizophrenia. Other psychiatric disorders such as depressive disorders recur across the life span, but even bipolar disorder, classically characterized as episodic, can run a chronic course.
3. The symptoms of psychiatric disorders often begin early, impairing the ability of children and adolescents to learn and compromising the functioning of adults at work and in other life roles. As a result of their high prevalence, early onset, and persistence, psychiatric disorders contribute substantially to the burden of illness in all countries in which they have been studied. In the United States they are not only a leading cause of disability but also a significant cause of premature death, because mood disorders, schizophrenia, and to some extent other psychiatric disorders constitute the most potent risk factors for suicide, a leading cause of death worldwide.

Blood glucose level
1. The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis.
2. Glucose is the primary source of energy for the body’s cells, and blood lipids (in the form of fats and oils) are primarily a compact energy store. Glucose is transported from the intestines or liver to body cells via the bloodstream, and is made available for cell absorption via the hormone insulin, produced by the body primarily in the pancreas.
3. The mean normal blood glucose level in humans is about 5.5 mmol/L; however, this level fluctuates throughout the day. Glucose levels are usually lowest in the morning, before the first meal of the day (termed «the fasting level»), and rise after meals for an hour or two by a few millimolar.
4. Blood sugar levels outside the normal range may be an indicator of a medical condition. A persistently high level is referred to as hyperglycemia; low levels are referred to as hypoglycemia. Diabetes mellitus is characterized by persistent hyperglycemia, and is the most prominent disease related to failure of blood sugar regulation. Intake of alcohol causes an initial surge in blood sugar, and later tends to cause levels to fall. Also, certain drugs can increase or decrease glucose levels.

Drugs
1. In fact, all medicines are drugs. You take drugs for your headache or your asthma. But you need to remember that not all drugs are medicines. Alcohol is a drug, and nicotine is a drug. There are many drugs that do you no good at all. There’s nothing wrong with medicinal drugs if they’re used properly. The trouble is, some people use them wrongly and make themselves ill. Most of the drugs are illegal, but some are ordinary medical substances that people use in the wrong way.
2. People take drugs because they think they make them feel better. Young people are often introduced to drug-taking by their friends. Many users take drugs to escape from a life that may seem too hard to bear. Drugs may seem the only answer, but they are no answer at all. They simply make the problem worse. Depending on the type and strength of the drug, all drug-abusers are in danger of developing side effects. Drugs can bring on confusion and frightening hallucinations and cause unbalanced emotions or more serious mental disorders.
3. First-time heroin users are sometimes violently sick. Cocaine, even in small amounts, can cause sudden death in some young people, due to heartbeat irregularities. Children born to drug-addicted parents can be badly affected. Regular users may become constipated and girls can miss their periods. Some drugs can slow, even stop the breathing process, and if someone overdoses accidentally they may become unconscious or even die.
