Bac Blanc 2012 - Scientific Streams- Topic 2+Correction

PART I :

A fatty compound called cholesterol is one of the main substances involved in the formation of plaque. Cholesterol is found in many foods, including egg yolks, butter, and red meat. Eating both cholesterol and saturated fats seems to increase the amount of cholesterol in the blood. Most scientists recommend eating a diet low in overall fat, with cholesterol and saturated fats eaten most sparingly of all. They think that limiting the amount of fat eaten, especially saturated fat may also help people avoid certain types of cancer.
Eating a high-fat diet can contribute to excess consumption of calories which can lead to obesity. Obesity is overweight severe enough to pose a medical risk. People with obesity have an increased likelihood of many health problems, including diabetes, coronary artery disease, and a liver disorder called cirrhosis. In the United States, all processed foods must carry a label that states the amount of total cholesterol and saturated fat in a serving. This information is provided to help people control the amount of fat and calories in their diets.
People are advised not to let advertising influence the choice of the kind of food they want to eat. Many experts consider TV watching and TV advertisements a cause of overweight. They make people consume without thinking of their energy balance.
