Group 1: Sources of Sweetness - Sweetness primarily comes from natural sugars, artificial sweeteners, and natural substitutes. Natural sugars like sucrose, glucose, and fructose are found in fruits and honey, providing energy to the body. Artificial sweeteners, such as aspartame and saccharin, are chemically synthesized and offer high sweetness with minimal calories, catering to those managing sugar intake. Natural substitutes like erythritol and steviol glycosides are plant-derived, retaining sweetness with lower calories and minimal impact on blood sugar levels [1][2]. Group 2: Human Preference for Sweetness - The preference for sweetness is ingrained in human genetics and habits, as sweet foods typically indicate high energy content. Sugars are essential carbohydrates, providing 50%-70% of the energy required for life activities. Different types of sugars, including glucose and fructose, can be directly utilized by the body, while others need to be converted into monosaccharides for metabolism [2][3]. Group 3: Distinction Between "Sweet" and "Guan" - In Chinese culture, "甘" (sweet) and "甜" (sweet) have nuanced differences. "甘" is associated with a mild sweetness and medicinal properties, while "甜" refers solely to taste perception. For instance, honey is sweet and classified as "甘," but artificial sweeteners, though sweet, lack the health benefits associated with "甘" [3][4]. Group 4: Health Implications of Sweetness - Moderate consumption of sweet foods can benefit energy and digestion, but excessive intake may lead to health issues like obesity and dental problems. The recommended daily sugar intake is no more than 50 grams, ideally under 25 grams, especially for children and those with specific health conditions [6][7]. Group 5: Sugar Control Strategies - Effective sugar control involves distinguishing between natural and added sugars. Natural sugars found in fruits and dairy are generally safe, while added sugars in processed foods should be limited. Strategies include choosing whole foods, reducing sweet snacks, and being mindful of sugar content in pre-packaged items [8][9][10].
