Today we have already seems clear that the composition of our diet, but our lifestyle can affect our health, both good, and worse. The monitoring of the various components of our diet, food and drink can affect our bodies, is not only a large number of specialized physicians, as well as many other experts. It's not so long ago; doctors still did not pay such attention to the dietary regimen and health status, as we know it now. The beginnings of this research go back to the days when doctors evaluate the relationship between the serious deficiencies in the composition of food by people in a few developed regions of the world and their diseases. Most of these illnesses were caused by severe deficiencies of certain vitamins in the diet. Among the most important disease of this kind was one of rickets (vitamin D), blindness (due to lack of vitamin A ), beriberi (lack of vitamin B1 or thiamine) and scurvy (lack of vitamin C ). Over time, science began to pay attention to what people eat and drink in developed countries and how it negatively affects their health. Much of the population of industrialized countries is currently affected by atherosclerosis (narrowing of the internal lumen of arteries by depositing fatty substances). The cause may lead to cardiovascular diseases such as coronary heart disease, stroke or peripheral vascular disease). The most important cause of atherosclerosis is high levels of fat and especially cholesterol in the blood. This phenomenon is caused by excessive intake of dietary fat, especially in meat, eggs and dairy products. It excels for instance, compared with a low incidence of atherosclerosis in countries such as Japan, whose people consume diets poorer in fat and contain mostly unsaturated fats such as fish or seafood. Another important risk factor is obesity. It increases the possibility of many diseases such as diabetes, coronary heart disease or stroke, and more. It is caused by excess energy intake than obese handicapped person really needs. Alcohol is the cause of a wide range of diseases. His excessive drinking can lead to cirrhosis of liver, brain damage, peripheral neuritis, or cardiomyopathy. Alcohol is also associated with pancreatitis, cancer of the esophagus and many other diseases. Alcoholics are prone to malnutrition. Although it is not so well known, the emergence of some diseases of stomach-intestinal tract may be a lack of fiber. Pulp (whole meal bread or vegetables) meets a sufficient number of colon and helps regulate the absorption of nutrients from the small intestine. The deficiency may be one of the causes of diverticulitis, chronic constipation and hemorrhoids. In genetically predisposed individuals may be excessive salt consumption by one of the causes of hypertension in patients at medium-, age. Comparison of dietary habits in various countries suggests that our diet may be one factor in some forms of cancer. A high dietary fat and meat are probably linked increased risk of developing colon cancer. Food infected mold can cause liver cancer and esophagus. There are also allergies to food. One of these diseases is celiac disease, which is caused by intolerance to gluten (a protein contained in some cereals). Allergies to seafood may cause some diseases, such as hives. Also, some episodes of asthma and eczema may be caused by fear of allergies such as eggs or dairy products.
