What is sugar and what does it do in the body?

Sugar refers to simple carbohydrates such as glucose and sucrose. It is quickly absorbed and used to raise blood glucose and provide rapid energy.

Is sugar ever useful for health or performance?

Yes. Fast-acting sugar (especially glucose) can help treat mild-to-moderate hypoglycemia, and carbohydrates consumed during prolonged intense exercise can support performance.

How much sugar should I have per day?

Many people aim to limit added sugar; a common practical range is about 25–60 g per day depending on individual needs and total calorie intake. People with diabetes or specific health conditions may need stricter targets.

What are the risks of too much sugar?

Excess added sugar can contribute to weight gain, dental caries, and poorer cardiometabolic health, especially when it displaces nutrient-dense foods. Frequent sugary drinks are a common source of overconsumption.

What is the difference between natural sugars and added sugars?

Natural sugars occur in foods like fruit and milk, which also provide fiber or protein and micronutrients. Added sugars are put into foods and drinks during processing or preparation and are easier to consume in excess.
