*Sugar and health*
The impact of sugar on health, particularly focusing on added sugars or free sugars, has been a topic of extensive research and public discourse. Here's what the current understanding suggests:
*General Impact on Health:*
*Obesity and Weight Gain:* Sugar, especially in liquid form like sodas, contributes to weight gain due to its high calorie content without providing satiety or nutritional value. This can lead to obesity, which is a risk factor for numerous health conditions.
*Cardiovascular Health:* High intake of added sugars has been associated with increased risk factors for heart disease, such as high blood pressure, inflammation, and adverse changes in blood lipids (like increased triglycerides).
*Diabetes*: Excessive sugar consumption, particularly fructose, can lead to insulin resistance, a precursor to type 2 diabetes. It also contributes to the overall metabolic syndrome, which includes obesity, high blood pressure, and abnormal cholesterol levels.
*Dental Health:* Sugars, particularly when consumed frequently, increase the risk of dental caries by providing a substrate for bacteria in plaque to produce acids that erode tooth enamel.
*Liver Disease:* High fructose intake, typically from added sugars, can lead to non-alcoholic fatty liver disease (NAFLD) due to its metabolism which occurs primarily in the liver, potentially leading to more severe liver conditions.
*Mental Health:* There's emerging evidence suggesting a link between high sugar diets and increased risk of depression, possibly due to the inflammatory effects of sugar or its impact on neurotransmitter systems.
*Cancer:* While not directly causing cancer, sugar's contribution to obesity and inflammation might play a role in cancer development or progression, particularly in cancers linked with obesity like colorectal cancer.
*Mechanisms Behind Sugar's Effects:*
Inflammation: Diets high in sugar can lead to systemic inflammation, which is implicated in many chronic diseases including heart disease,
, and potentially neurodegenerative disorders.
*Glycation:* The process where sugar molecules attach to proteins or fats without the controlling action of an enzyme, leading to advanced glycation end products (AGEs). These are implicated in aging, diabetes complications, and other chronic conditions.
