营养素名称: Total Sugars
营养素类别: 碳水化合物和糖类 (Carbohydrates)
计量单位: g
概要: Sugar provides calories, or "energy," for the body. Total Sugars on the Nutrition Facts label include:
• sugars naturally presented in foods and beverages
• added sugars

Lower consumption of sugar-sweetened foods and beverages can reduce risk of developing cardiovascular disease and teeth cavities.
营养素功效: • Sugar provides calories, or "energy," for the body.
• Glucose in the blood (blood sugar) is the primary energy source for the body’s cells, tissues, and organs (such as the brain and muscles).
• The central nervous system (brain) have an absolute requirement for glucose.
• Glucose can be used immediately or stored in the liver and muscles for later use.

Classification of Dietary Carbohydrates based on sugar units:
monosaccharides (glucose or fructose in fruits): 1 sugar unit
disaccharides (sucrose, lactose in milk, and maltose): 2 sugar units
oligosaccharides (raffinose and stachyose): 3-10 sugar units
polysaccharides (starch and glycogen): 10+ sugar units

Sugars naturally present in foods and beverages, they are usually in the form of fruits or vegetables, milk, starch foods.
Added sugars: added during food processing, added as sweeteners, sugars from syrups and honey. Recommend to take less than 50 grams per day of added sugars based on a 2,000 calorie daily diet.
Starches: 1) amylose starches: compact, low solubility, and are less rapidly digested. 2) amylopectin starches: more rapidly digested. Enzymes break starches into monosaccharides which are then absorbed into the bloodstream. More slowly absorbed starchy foods (low Glycemic Index) may have health advantages, such as reduce the risk of Type II diabetes and cardiovascular disease.

概要 Sugar provides calories, or "energy," for the body. Total Sugars on the Nutrition Facts label include:
• sugars naturally presented in foods and beverages
• added sugars

Lower consumption of sugar-sweetened foods and beverages can reduce risk of developing cardiovascular disease and teeth cavities.
缺乏营养对健康的影响 Extreme low sugar intake, especially if it results in very low carbohydrate consumption, can have several health risks. For example:
Energy Levels: carbohydrates, including sugars, are a primary source of energy for the body. Severely restricting sugar can result in low energy levels, fatigue, and difficulty maintaining physical and mental performance.
Hypoglycemia: too low blood sugar levels can cause dizziness, confusion, sweating, shakiness, and even loss of consciousness in severe cases.
Mental Health: glucose is required for the brain central nervous system. Glucose deficiency can affect mood, concentration, and cognitive function, potentially leading to irritability, depression, and difficulty concentrating. And can even impair the development of the central nervous system.
超过上限对健康的影响

  • Obesity: high sugar intake can lead to weight gain and obesity.
  • Type 2 Diabetes: excessive sugar consumption can cause body's cell less responsive to insulin (insulin resistance) , and eventually may result in type 2 diabetes.
  • Heart Disease: high sugar intake can lead to higher levels of triglycerides, high blood pressure, and inflammation. These are the risk factors for heart diseases.
  • Dental Problems: sugar is a major contributor to tooth decay and cavities. Bacteria in the mouth feed on sugar and produce acid, which erodes tooth enamel.
  • Skin Aging: High sugar intake can accelerate skin aging through a process called glycation, where sugar molecules bind to proteins in the skin, causing it to lose elasticity and firmness.
  • Cancer Development and Progression: some research found the relationships between sugar and cancer, especially fructose. It is a complex and nuanced topic. The primary reasons for this association are:
    1. Energy Source: cancer cells consume more glucose than normal cells because they are rapidly growing and dividing, which requires a lot of energy.
    2. Insulin and Growth Factors: high sugar intake can lead to increased levels of insulin and insulin-like growth factors in the blood. These hormones can promote cell growth and potentially contribute to the development and progression of cancer.
    3. Inflammation: high sugar intake may cause over weight and obesity. Excess body fat can lead to chronic inflammation and hormonal imbalances, which may increase the risk of certain types of cancer.
