A widely environmental problem occurring worldwide is the issue of fat in our daily diet. There are different types of fat but the two broad categories of fat are saturated fat and unsaturated fat. There are a number of saturated fatty acids. The major ones are lauric, myristic, palmitic and stearic acid. The difference between these saturated and unsaturated fat is their chemical structure. Saturated fats are fats with a single bond between the carbon atoms of the fatty acids and the carbon atoms are attached with the hydrogen atoms. Unlike unsaturated fat, saturated fatty acids have no double bonds. Because of its chemical structure, the saturated fatty acid chains have no gaps which they are able to pack together tightly with CH2 molecules. CH2 is a chemical where a carbon atom is bonded to two hydrogen atoms. As the tightly packed saturated fat goes through the bloodstream, it will increase bad cholesterol in the body. Saturated fat is usually solid at room temperature whereas unsaturated fat is liquid at room temperature that tends to be healthier. Saturated fat is the fat that we are most concerned of because it is unhealthy for our diet that leads to many kinds of health issues.
Saturated fats are causing problems to people because it is increasing the rate of people in obesity. The junk food where large amounts of saturated fats contained made many Americans has health problems. About 60% to 70% Americans are overweight and obese and being obese is the start of getting a higher risk to heart disease, diabetes and high blood pressure. In the year 2005, about 1.6 billion adults ages 15 and over were overweight, and at least 400 million adults were obese. In 2010, an estimated of 42 million children under age of 5 years are overweight globally. Also, the World Health Organization is concerning about childhood obesity that is increasing now because the excess intake of saturated fat foods will make them have heart diseases and diabetes at a young age. This is a major concern because children of all races, incomes and U.S. regions commonly eat fast foods.
