How many grams of sugar are considered bad?

4 min read

According to the American Heart Association (AHA), adult women should consume no more than 25 grams of added sugar daily, while the World Health Organization (WHO) suggests an even lower limit for additional health benefits. The question of how many grams of sugar are considered bad hinges on a distinction between natural and added sugars and adhering to specific, low daily thresholds to avoid negative health outcomes.

Quick Summary

Different health organizations recommend varying, but consistently low, daily limits for added sugars to avoid health risks. For most adults, a threshold significantly lower than 50 grams is recommended, with sources like soda and processed foods being the main contributors to excessive consumption, which is linked to weight gain, heart disease, and diabetes.

Key Points

  • Added vs. Natural Sugars: The key distinction is between added sugars in processed foods and natural sugars found in whole foods like fruit. It's the added sugars that are the primary concern for health.

  • Daily Limits for Added Sugar: The American Heart Association recommends no more than 36g for men and 25g for women daily. The World Health Organization suggests staying under 25g for additional benefits.

  • Health Risks of Excess Sugar: Overconsumption of added sugar contributes to weight gain, heart disease, type 2 diabetes, fatty liver disease, and dental problems.

  • Liquid Calories are Major Culprits: Sugary drinks like sodas, juices, and energy drinks are significant sources of added sugar and are easily over-consumed because they don't promote fullness.

  • How to Reduce Intake: Practical strategies include reading nutrition labels for 'Added Sugars', choosing plain versions of foods like yogurt and oatmeal, and prioritizing water over sweetened beverages.

  • Taste Buds Can Adapt: By gradually reducing your sugar intake, you can retrain your palate to be satisfied with less sweetness over time.

  • Hidden Sugars are Common: Be aware that sugar is added to many savory processed foods like sauces, dressings, and condiments, so checking labels is crucial.

Understanding the 'Added' vs. 'Natural' Sugar Distinction

One of the most important factors in determining how many grams of sugar are considered bad is distinguishing between naturally occurring sugars and added sugars. Naturally occurring sugars are those found intrinsically within whole foods like fruits and vegetables, bundled with fiber, vitamins, and minerals. The fiber in these foods slows sugar absorption, preventing sharp blood glucose spikes. Added sugars, conversely, are sugars and syrups that are added to foods and drinks during processing, preparation, or at the table. These often provide 'empty calories' without any nutritional benefit and are absorbed quickly by the body, leading to rapid blood sugar and insulin fluctuations.

The Health Hazards of Excessive Added Sugar

Overconsuming added sugars has been extensively linked to numerous adverse health effects. Beyond the obvious weight gain due to high calorie density, excessive sugar consumption can lead to more serious chronic conditions.

  • Increased Risk of Heart Disease: High sugar intake has been shown to raise blood pressure and increase chronic inflammation, both key risk factors for heart disease. A 15-year study found that people who derived 17–21% of their calories from added sugar had a 38% higher risk of death from cardiovascular disease.
  • Higher Risk of Type 2 Diabetes: Consistently high sugar intake can lead to insulin resistance, where the body's cells stop responding effectively to insulin, causing blood sugar levels to rise. This is a major risk factor for developing type 2 diabetes.
  • Non-Alcoholic Fatty Liver Disease (NAFLD): The liver metabolizes fructose, a type of sugar commonly used in sweetened beverages. Too much fructose can overload the liver, leading to excess fat accumulation.
  • Dental Health Issues: Oral bacteria feed on sugar and produce acid, which erodes tooth enamel and leads to cavities and decay.
  • Weight Gain and Obesity: Sugary beverages, in particular, do not trigger the same satiety signals as solid foods, making it easy to consume a large number of empty calories without feeling full. This can cause a leptin resistance and disrupt appetite control over time.
  • Skin Aging: Consuming high amounts of sugar leads to the formation of advanced glycation end products (AGEs), which damage collagen and elastin, proteins that keep skin firm and youthful.

Official Daily Added Sugar Recommendations by Health Organizations

While there is no official Daily Value for total sugars, major health bodies provide specific recommendations for limiting added sugars. Adhering to these guidelines can significantly reduce the risk of associated health problems.

Organization Maximum Daily Added Sugar (Men) Maximum Daily Added Sugar (Women) Reference
American Heart Association (AHA) 36 grams (9 teaspoons or 150 calories) 25 grams (6 teaspoons or 100 calories)
World Health Organization (WHO) Preferably under 25 grams (less than 5% of total calories) Preferably under 25 grams (less than 5% of total calories)
Dietary Guidelines for Americans Up to 50 grams (less than 10% of total calories based on 2,000-calorie diet) Up to 50 grams (less than 10% of total calories based on 2,000-calorie diet)

The Importance of the 5% Rule

The World Health Organization's recommendation to reduce free sugar intake to less than 5% of total daily energy intake (equivalent to about 25 grams) is significant. Studies show that meeting this lower target provides additional health benefits beyond the 10% guideline. Many packaged products contain more than this limit in a single serving, emphasizing the importance of reading nutrition labels carefully. Common culprits include soda, sweetened cereals, flavored yogurts, and many sauces and condiments.

Practical Steps for Reducing Your Sugar Intake

To stay within healthy limits, focus on reducing your intake of added sugars, particularly from liquid calories and processed snacks. This shift can not only improve your health but also recalibrate your taste buds, making you less reliant on overly sweet foods.

  • Switch Your Beverages: Replace sugary drinks like soda, juices, and sweetened teas with water, herbal tea, or seltzer with a splash of fruit.
  • Read Nutrition Labels: Scrutinize the 'Added Sugars' line on the Nutrition Facts panel. Be wary of products that list sugar near the top of the ingredient list and watch for its many aliases, such as sucrose, high-fructose corn syrup, and dextrose.
  • Choose Whole Foods: Prioritize eating whole foods like fresh fruits, vegetables, whole grains, and lean proteins. These contain natural sugars alongside fiber and other nutrients that promote satiety and stable blood sugar levels.
  • Opt for Plain Versions: Buy plain yogurt, oatmeal, and cereal, and add your own natural sweeteners like fresh berries or cinnamon. You control the sugar content and avoid the excessive amounts found in pre-flavored products.
  • Bake Smarter: When baking, try reducing the amount of sugar called for in recipes. Many recipes can be adapted to use less sugar without sacrificing taste, and you can supplement sweetness with mashed bananas or applesauce.

Conclusion: The Path to a Balanced Diet

Ultimately, there is no single, one-size-fits-all answer for how many grams of sugar are considered bad, but major health organizations provide clear guidance on limiting added sugars. The consensus is to keep added sugar consumption well below the amount found in many processed foods and sugary drinks. By focusing on whole, nutrient-dense foods and becoming a savvy label reader, you can significantly reduce your daily intake of empty calories. Moderation is key, and understanding the difference between natural and added sugars empowers you to make smarter dietary choices that support long-term health and well-being. A controlled intake of added sugar helps mitigate the risks of weight gain, heart disease, diabetes, and other chronic illnesses, paving the way for a healthier lifestyle.

Frequently Asked Questions

For an average adult on a 2,000-calorie diet, the Dietary Guidelines for Americans recommend limiting added sugars to less than 10% of total daily calories, which is about 50 grams. However, more stringent guidelines from the AHA recommend 36 grams for men and 25 grams for women.

The sugar naturally present in whole fruits is not considered bad. It is 'packaged' with fiber, vitamins, and minerals that slow its absorption and offer nutritional benefits. The primary health concern is the excessive consumption of 'added sugars'.

Added sugars provide 'empty calories' without fiber or other essential nutrients, leading to rapid blood sugar spikes and crashes. Natural sugars in whole foods, like fruit, are absorbed more slowly due to the presence of fiber, providing a more stable energy source.

Excessive sugar intake is linked to weight gain, increased risk of heart disease, type 2 diabetes, non-alcoholic fatty liver disease (NAFLD), acne, accelerated skin aging, and tooth decay.

Added sugars can be found in many unexpected products, including sweetened beverages, fruit juices, flavored yogurts, breakfast cereals, granola bars, and condiments like ketchup, sauces, and salad dressings.

Focus on consuming whole, unprocessed foods, and actively read nutrition labels to check for 'Added Sugars'. Replace sugary drinks with water and sweeten plain foods like yogurt and oatmeal with fresh fruit instead of processed alternatives.

While sugar itself doesn't directly cause diabetes in healthy individuals, excessive intake contributes significantly to weight gain and insulin resistance. Both are major risk factors for developing type 2 diabetes over time.
