Sugars, especially glucose, are a major source of energy for all living things. Plants produce glucose by photosynthesis and convert that and other monosaccharides into various disaccharides such as sucrose (table sugar) or convert it into starch to store it more easily. Animals which eat these plants can make use of this energy source and also are attracted to the sweet taste and smell. We frequently add sugar to foods that normally and naturally do not have it (or have it only in small quantities) just because we crave the taste of it for its own sake. As our sugar consumption has risen in western nations, so have our rates of the “stress” diseases: diabetes and hypoglycemia, heart and circulatory problems, dental caries, malnutrition, decreased resistance to infections, etc.
Around 100 years ago, the average American consumed about 40 lb. of sugar per year. As of 1986, Americans were averaging a third of a pound of sugar per person (including children) per day, which comes to about 127 lb. per person per year. As of 1982, 25% of the average American’s intake of cane and beet sugar came from soft drinks. Soft drink consumption in the U. S. rose from 1.6 drinks per person per year in 1850 to 620 drinks per person per year in 1981. As of 1998, the average American sugar consumption has risen to 148 lb. per person per year, which is over 1/3 lb. or 600 Kcal per day! According to a study by US Department of Health and Human Services, between the years 2005-2008, approximately half the US population consumes sugar drinks on any given day with 52% of the population consuming at least one 12-oz cans of soda per day. In this experiment, we will analyze a number of types of soft drinks to see how much sugar they contain.
Determine the amount of sugar in sodas or other sugar containing beverages by extrapolating from graphical data. The data we will graph is the average solution density versus mass % sugar in sugar solutions.
