Added Sugar: How Much Is Too Much and Why It Matters for Your Health?

Sugar is everywhere. It can be found not only in sweets and soft drinks but also in foods that many people consider healthy, such as breakfast cereals, flavoured yoghurts, granola bars, plant-based drinks, salad dressings, and sauces.

While enjoying something sweet occasionally is not a problem, regularly consuming too much added sugar may negatively affect health over time. Understanding where added sugar hides, how it differs from naturally occurring sugars, and how much is recommended can help you make informed choices without feeling deprived.

What Is Added Sugar?

Added sugars are sugars and syrups that are added to foods and beverages during processing, preparation, or cooking. Examples include:

• White sugar

• Brown sugar

• Cane sugar

• High-fructose corn syrup

• Rice syrup

• Agave syrup

• Maple syrup

• Coconut sugar

• Dextrose

• Maltose

Even ingredients that sound more natural are still considered added sugars when they are used to sweeten foods.

Added sugars differ from naturally occurring sugars found in whole fruits, berries, vegetables, and unsweetened dairy products.

Added Sugar vs Natural Sugar

Not all sugars affect health in the same way.

For example, an apple contains naturally occurring sugars, but it also provides fibre, vitamins, minerals, water, and beneficial plant compounds. The fibre slows digestion and helps moderate the rise in blood sugar after eating.

A sugary soft drink (for example Coca Cola, Sprite, Fanta, Pepsi etc) may contain a similar amount of sugar, but it provides little or no nutritional value and is quickly absorbed by the body.

The concern is not the sugar naturally present in whole foods. Most health recommendations focus on limiting added sugars and free sugars, particularly from highly processed foods and beverages.

How Much Added Sugar Is Recommended?

The World Health Organization recommends limiting free sugar intake to less than 10% of total daily energy intake. Additional health benefits may be achieved by reducing intake to below 5%.

For someone consuming 2,000 calories from food and drinks per day:

• 10% equals approximately 50 grams (12 teaspoons) of sugar

• 5% equals approximately 25 grams (6 teaspoons) of sugar

1tsp sugar = 4 g of sugar

Many people exceed these amounts without realising it, especially when consuming sweetened drinks, desserts, breakfast products, and processed snacks regularly.

Why Too Much Added Sugar Can Be Harmful

Occasional treats are unlikely to cause health problems. However, consistently high intakes of added sugar may contribute to several health concerns.

Weight Gain and Obesity

Sugary foods and drinks can be easy to overconsume because they provide calories without promoting the same level of fullness as protein-rich or fibre-rich foods.

Research suggests that sugar-sweetened beverages are particularly associated with weight gain because liquid calories are less satisfying than calories from whole foods.

Type 2 Diabetes and Blood Sugar Imbalances

Regular consumption of sugary beverages and highly processed foods has been linked to an increased risk of type 2 diabetes.

While sugar itself does not directly cause diabetes, excessive intake may contribute to weight gain, insulin resistance, and metabolic dysfunction, all of which increase diabetes risk.

Cardiovascular Disease

High intakes of added sugar have been associated with elevated triglycerides, increased inflammation, higher blood pressure, and other risk factors for cardiovascular disease.

A heart-healthy diet focuses on whole foods, healthy fats, fibre-rich carbohydrates, and minimal consumption of highly processed sugary foods.

Non-Alcoholic Fatty Liver Disease (NAFLD)

Excessive intake of fructose-containing sweeteners may contribute to fat accumulation in the liver, especially when consumed in large amounts from sugary beverages and ultra-processed foods.

Dental Health

Oral bacteria feed on sugars and produce acids that damage tooth enamel. Frequent consumption of sugary foods and drinks increases the risk of cavities and dental decay.

Poor Diet Quality

When sugary foods replace nutrient-dense foods, people may get fewer vitamins, minerals, fibre, and protein. This can make it more difficult to meet nutritional needs despite consuming enough calories.

Hidden Sources of Added Sugar

Many foods that are not obviously sweet can contain significant amounts of added sugar.

Common examples include:

• Breakfast cereals

• Flavoured yoghurts

• Granola

• Protein bars

• Sports drinks

• Energy drinks

• Plant-based milks

• Ketchup

• Barbecue sauces

• Salad dressings

• Pasta sauces

• Packaged soups

• Flavoured oatmeal

Reading ingredient lists and nutrition labels can help identify products with unexpectedly high sugar content.

Common Names for Sugar on Ingredient Labels

Manufacturers may use many different names for added sugars.

Examples include:

• Sugar

• Brown sugar

• Raw sugar

• Buttered syrup

• Nectars (for example, peach or pear nectar)

• Corn syrup solids

• Fructose

• Glycose

• Glycose solids

• Maltose

• Sorbitol

• Sorghum syrup

• Sucrose

• Ribose

• Saccharose

• Galactose

• Lactose

If several of these ingredients appear near the beginning of the ingredient list, the product may contain a substantial amount of added sugar.

What About Artificial Sweeteners?

Artificial and non-sugar sweeteners remain a topic of ongoing research.

Some studies suggest potential effects on appetite regulation, gut microbiota, and metabolic health, while others indicate that replacing sugar-sweetened beverages with low-calorie alternatives may help reduce overall calorie intake.

Current evidence suggests that artificial sweeteners should not be viewed as a magic solution. Rather than replacing large amounts of sugar with sweeteners, many people benefit from gradually reducing their preference for intensely sweet foods and drinks altogether.

Practical Ways to Reduce Added Sugar

Reducing added sugar does not require giving up all sweet foods.

Small, sustainable changes often work best.

Drink More Water

Replace soft drinks, sweetened coffees, and sugary juices with water, sparkling water, herbal teas, or other unsweetened beverages.

Choose Plain Yoghurt

Buy plain yoghurt or kefir and add fresh berries, fruit, cinnamon, or nuts instead of choosing sweetened varieties.

Eat More Whole Foods

Meals built around vegetables, fruit, legumes, nuts, seeds, quality protein sources, and minimally processed foods naturally contain less added sugar.

Read Labels

Compare products and choose options with less added sugar whenever possible.

Reduce Sugar Gradually

If you usually add sugar to coffee, tea, or recipes, reduce it little by little. Taste preferences often adapt over time.

Prioritise Protein and Fibre

Balanced meals that contain protein, healthy fats, and fibre can help improve satiety and reduce cravings for sugary snacks.

Here are examples of different forms of sugars in some foods and drinks sold in Estonia.

Do You Need to Eliminate Sugar Completely?

For most people, the answer is no.

A healthy diet does not require perfection. Occasional desserts, celebrations, and favourite treats can fit within an overall balanced eating pattern.

Rather than focusing on eliminating sugar completely, a more sustainable approach is to:

• Limit added sugars most of the time

• Choose whole foods more often

• Build balanced meals with protein, fibre, and healthy fats

• Be mindful of sugary drinks and ultra-processed foods

These habits can support long-term health without creating unnecessary restriction around food.

Final Thoughts

Added sugar is not inherently harmful when consumed occasionally, but excessive intake can contribute to weight gain, blood sugar imbalances, cardiovascular disease, fatty liver disease, dental problems, and poor diet quality.

The good news is that small changes can make a meaningful difference. Reading labels, reducing sugary beverages, and prioritising whole foods are simple steps that can help lower added sugar intake while still allowing room for enjoyment and flexibility.

After all, good nutrition is not about perfection—it is about building habits that support your health for the long term.
