タイトルまたは説明

Sugars are found in the tissues of most plants and are present in sufficient concentrations for efficient commercial extraction in  sugarcane and  sugar beet. The world production of sugar in ***1 was about **8 million tonnes. The average person consumes about *4 kilograms (*3 lb) of sugar each year (*3.1 kg in industrialised countries), equivalent to over **0 food calories per person, per day. Since the latter part of the twentieth century, it has been questioned whether a diet high in sugars, especially refined sugars, is good for human health. Sugar has been linked to obesity, and suspected of, or fully implicated as a cause in the occurrence of diabetes, cardiovascular disease, dementia, macular degeneration, and tooth decay. Numerous studies have been undertaken to try to clarify the position, but with varying results, mainly because of the difficulty of finding populations for use as controls that do not consume or are largely free of any sugar  consumption.
