Excessive sugar, especially fructose, can overload liver processing capacities, similar to excess alcohol. This can lead to fat buildup in liver cells, also called non-alcoholic fatty liver disease (NAFLD).
Sugars are a major cause of dental cavities. As mouth bacteria feed on sugar, it creates acids that erode tooth enamel, leading to cavities. Regular intake of sugary snacks/drinks boosts mouth acid, speeding decay.
