Core Viewpoint - The article emphasizes the potential health risks associated with the consumption of processed foods containing various food additives, highlighting a significant correlation between these additives and chronic diseases such as type 2 diabetes [4][6][10]. Group 1: Health Risks of Food Additives - Processed foods often contain food additives like modified starch, pectin, and natural colorants, which enhance taste and appearance but may pose health risks [4]. - A study published in PLOS Medicine indicates that long-term consumption of food additives in combination may be linked to the onset of chronic diseases [4][6]. - The article warns that even single additives deemed safe can have complex biological effects when mixed with other ingredients, necessitating a reevaluation of dietary habits [4][6]. Group 2: Synergistic Effects of Additives - The article discusses the underestimated synergistic effects of food additives, which can lead to unexpected health risks similar to drug interactions [6][9]. - Existing research has shown that emulsifiers can disrupt gut microbiota balance, while artificial sweeteners may affect metabolic functions, yet their long-term impacts in real dietary contexts remain unclear [6][9]. - The need for comprehensive studies to assess the combined health effects of food additives is highlighted, as traditional safety evaluations focus on individual components [6][9]. Group 3: Large-Scale Study Findings - A large-scale study in France tracked the dietary habits of 108,643 adults over 7.7 years, analyzing 269 common additives and identifying 75 frequently consumed ones [7]. - The study categorized these additives into five typical combinations, revealing patterns in their occurrence within specific food categories [7]. - Notably, certain high-frequency additive combinations, such as emulsifiers and preservatives, may be linked to metabolic disorders, indicating a need for further health risk research [7][8].

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].
