Most adults are advised to keep added or “free” sugars low: many national and international guidelines fall between about 25–36 g per day for adults, with stricter limits now pushing toward “as little as possible” rather than a precise allowance. Natural sugars in whole fruits, vegetables, and plain dairy are generally not the main concern; the focus is on sugars added to foods and drinks.

Key daily numbers

  • Common health‑organization targets are:
    • Around 25 g per day (6 teaspoons) of added or free sugars for many women and for kids over 2.
* Around 36 g per day (9 teaspoons) of added sugars for many men.

* The UK’s NHS suggests no more than 30 g of free sugars a day for adults and lower limits for children depending on age.
  • The World Health Organization recommends keeping free sugars under 10% of daily calories, and ideally closer to 5% (about 25 g) for additional health benefits.

Added vs “free” vs natural sugar

  • Added sugars : Sugar added during processing, cooking, or at the table (table sugar, syrups, sugars in sweets and soda). These are what most limits refer to.
  • Free sugars : Added sugars plus those naturally present in honey, syrups, fruit juices, and fruit juice concentrates.
  • Naturally occurring sugars in whole fruit, vegetables, and unsweetened dairy are wrapped in fiber and nutrients and are not the main target of intake limits.

Why keeping sugar low matters

  • High intake of added/free sugar is linked to higher risk of weight gain, type 2 diabetes, and heart disease, especially when a lot comes from sugary drinks.
  • Frequent sugary foods and drinks also raise the risk of tooth decay, which is one reason many countries have tightened sugar guidance in recent years.

Examples in everyday food

  • A typical can of regular soda can contain close to or more than an entire day’s added sugar allowance (around 30–40 g).
  • Sweetened yogurts, breakfast cereals, and “healthy” granola bars can each carry 10–30 g of added sugar per serving, so just a couple of these in a day can exceed recommended limits.

Practical tips to stay within limits

  • Check nutrition labels for “added sugars” or “of which sugars” and aim to keep most meals under about 8–10 g of added sugar if you eat multiple times per day.
  • Prioritize:
    • Whole fruits instead of juices.
    • Plain yogurt and unsweetened cereals, adding fruit or a small drizzle of honey if needed.
    • Water, coffee, or tea without added sugar instead of soft drinks and sweetened coffees.
