What Are Added Sugars?
Added sugars are sweeteners that are incorporated into foods and beverages during processing, manufacturing, or preparation. These sugars include table sugar, high fructose corn syrup, honey, and various syrups. They are commonly found in a wide range of processed items, such as candy, sweetened cereals, baked goods, and fruit drinks.
Sources of Added Sugars
The main sources of added sugars in the American diet are sugar-sweetened beverages, desserts, sweet snacks, sweetened coffee and tea, and candy. These sugary products often contain high amounts of added sugars, which can contribute to excess calorie intake and various health concerns.
Dietary Guidelines for Added Sugar
The Dietary Guidelines for Americans recommend limiting added sugar intake to less than 10% of total daily calories. For a 2,000-calorie diet, this equates to no more than 200 calories or about 12 teaspoons of added sugar per day. Understanding the Nutrition Facts label can help identify the amount of added sugars in food products and make informed choices.
Labels may indicate « sugar-free » (less than 0.5g of sugar per serving), « reduced sugar » (at least 25% less sugars per serving), « no added sugars » (no sugars added during processing), or « low sugar » (not clearly defined as a claim). Paying attention to these labels and the ingredient list can assist in limiting consumption of excess added sugars.
Consuming too much added sugar is linked to weight gain, obesity, type 2 diabetes, and other chronic health concerns. By understanding the sources and recommended limits for added sugars, individuals can make healthier choices and reduce the impact of excess added sugar consumption.
Weight Gain and Obesity Risks
Consuming too many added sugars, especially from sugary beverages, can contribute to weight gain and obesity. Sugar-sweetened drinks like sodas, juices, and sweetened teas are loaded with fructose, a type of simple sugar that doesn’t curb hunger and can lead to overconsumption of calories. Excessive fructose intake has also been linked to increased abdominal fat and insulin resistance, both of which raise the risk of obesity.
Impact on Hunger and Cravings
Studies have shown that people who regularly drink sugary soda are much more likely to gain weight than those who don’t (2, 3, 4). In fact, people who drank soda alongside their normal diet consumed 572 more calories per day, potentially leading to significant weight gain over time (5). This is likely due to the way the body processes fructose, which can disrupt hunger and satiety signals, leading to increased calorie intake and weight gain.
Similarly, high-sugar coffee drinks and other sweet treats like ice cream and french fries can also contribute to weight gain and increase the risk of heart disease, stroke, and type 2 diabetes (3, 10, 12, 13, 22, 25, 26).
| Food Item | Calorie Content | Potential Impact |
|---|---|---|
| Soda | Up to 572 calories per day | Significant weight gain over time |
| High-sugar coffee drinks | High in calories and sugar | Weight gain, heart disease, stroke, type 2 diabetes |
| Ice cream | High in sugar and fat | Weight gain |
| French fries | Around 378 calories per serving | Weight gain, heart disease |
It’s clear that the link between added sugars and weight gain, as well as the role of sugary beverages in obesity, is a significant public health concern. Reducing consumption of these foods and drinks is an important step in maintaining a healthy weight and reducing the risk of chronic diseases.
Heart Disease and Stroke Risks
Consuming too many added sugars can have a significant impact on your heart health. Studies have shown a clear connection between high added sugar intake and an increased risk of developing cardiovascular disease and experiencing a stroke.
One of the primary ways added sugars contribute to heart disease is by promoting obesity. Diets high in added sugars, especially from sugary beverages, can lead to weight gain and obesity, which are major risk factors for heart disease. Additionally, excess added sugar consumption can raise triglycerides, blood pressure, and inflammation – all of which are detrimental to heart health.

Acne and Skin Aging Risks
The link between sugar intake and acne has been a subject of ongoing research. Studies suggest that a diet high in refined carbohydrates and added sugars can significantly contribute to the development and severity of acne. The spike in blood sugar and insulin levels triggered by sugary foods can increase androgen secretion, oil production, and inflammation – all of which are well-known factors that exacerbate acne.
In addition to the impact on acne, the consumption of too much sugar can also accelerate the skin aging process. The advanced glycation end products (AGEs) formed from the breakdown of sugars can damage collagen and elastin, the proteins responsible for skin’s firmness and elasticity. This can lead to premature wrinkles, sagging, and a dull complexion.
Effects on Inflammation and Glycation
A growing body of research indicates that the link between sugar and acne is largely driven by the inflammatory response and the formation of AGEs. Consuming high-glycemic foods, such as white bread, pastries, and sweetened beverages, can trigger a rapid spike in blood sugar and insulin levels. This, in turn, can increase the production of inflammatory molecules, leading to skin irritation and acne breakouts.
Furthermore, the impact of advanced glycation end products on skin aging is significant. AGEs can cross-link with collagen and elastin fibers, making them stiffer and less flexible. This can lead to a loss of skin elasticity, the development of fine lines and wrinkles, and an overall aged appearance.
« A balanced diet rich in fruits, vegetables, lean protein, healthy fats, and complex carbohydrates provides nutrients vital for skin health. »
To maintain healthy, youthful-looking skin, it’s essential to limit your intake of added sugars and opt for low-glycemic foods that won’t spike your blood sugar. Incorporating antioxidants, omega-3 fatty acids, and other skin-nourishing nutrients can also help mitigate the damaging effects of sugar on the skin.
Type 2 Diabetes Risk
Consuming excessive amounts of added sugars is a major risk factor for developing type 2 diabetes. A diet high in sugar can lead to weight gain and obesity, which are strong predictors of diabetes. Additionally, regularly eating large amounts of sugar can cause insulin resistance, where the body becomes less responsive to the hormone insulin, leading to elevated blood sugar levels and an increased risk of type 2 diabetes.
Insulin Resistance and Blood Sugar Spikes
The connection between added sugar intake and type 2 diabetes is well-established. Studies have shown that a higher consumption of ultra-processed foods, which are often high in added sugars, is associated with a significantly increased risk of developing type 2 diabetes. In fact, for every 10% increase in total ultra-processed food intake, the risk of type 2 diabetes increases by 12%.
Specific ultra-processed food subgroups that have been linked to a higher type 2 diabetes risk include refined breads, sauces, spreads, and condiments, as well as artificially and sugar-sweetened beverages, animal-based products, and ready-to-eat mixed dishes. On the other hand, cereals, dark and whole-grain breads, packaged sweet and savory snacks, fruit-based products, and yogurt and dairy-based desserts have been associated with a lower type 2 diabetes risk.
The impact of added sugar on insulin sensitivity is a key factor in the development of type 2 diabetes. Regularly consuming high amounts of sugar can lead to insulin resistance, where the body becomes less responsive to the hormone insulin. This can result in elevated blood sugar levels, a hallmark of type 2 diabetes. To manage the risk of type 2 diabetes, it is recommended to limit added sugar intake and focus on a diet rich in whole, minimally processed foods.

Cancer Risk Factors
Emerging research suggests that a diet high in added sugars may increase the risk of certain types of cancer, such as prostate, esophageal, and colorectal cancer. The proposed mechanisms linking sugar and cancer include the ability of excess sugar consumption to contribute to obesity, chronic inflammation, and insulin resistance – all of which are linked to an elevated cancer risk.
For instance, a study found an association between consumption of a food grouping including dessert foods, sweet beverages, and added sugars, and a 27% increased risk of breast cancer (adjusted odds ratio: 1.27, 95% confidence interval: 1.00-1.61). The risk was even higher, a 55% increase, when considering only dessert foods (odds ratio: 1.55, 95% confidence interval: 1.23-1.96), especially among premenopausal women (odds ratio: 2.00, 95% confidence interval: 1.32-3.04).
While more research is needed, limiting added sugar intake may be an important strategy for cancer prevention. It’s important to note that cutting out sugar from the diet does not prevent or treat cancer, and following severely restrictive diets could be dangerous, especially for cancer patients undergoing treatment.
« There’s no evidence that a ‘sugar-free’ diet lowers the risk of getting cancer or boosts survival chances post-diagnosis. »
Cancer cells require a lot of glucose for energy due to their quick growth rate, which is why some researchers are exploring drugs that shut down cancer cells’ powerplants while allowing healthy cells to continue making energy. However, the focus should remain on adopting a balanced, nutritious diet and limiting added sugars as part of a comprehensive cancer prevention strategy.
- Association between consumption of a food grouping including dessert foods, sweet beverages, and added sugars positively associated with breast cancer risk (adjusted odds ratio comparing highest to lowest quartile: 1.27, 95% confidence interval: 1.00-1.61).
- Stronger association with breast cancer risk observed when considering only dessert foods, with a 55% increase in risk for those in the highest quartile of dessert consumption compared to the lowest quartile (odds ratio: 1.55, 95% confidence interval: 1.23-1.96).
- Higher risk of breast cancer associated with desserts noted among premenopausal women (odds ratio: 2.00, 95% confidence interval: 1.32-3.04) compared to postmenopausal women (odds ratio: 1.40, 95% confidence interval: 1.07-1.83).

Mental Health Impacts
Emerging research suggests that a diet high in added sugars and processed foods may have a significant impact on mental health. Several studies have found a concerning link between increased sugar consumption and a higher risk of depression in both men and women.
The proposed mechanisms behind this relationship include sugar-induced inflammation, insulin resistance, and disruptions to the brain’s reward system – all of which can profoundly influence mood and emotions. Men who consume more than 40 grams of sugar per day have a higher risk of being diagnosed with depression in the following years.
Fortunately, limiting added sugars may be an important strategy for supporting mental wellbeing. A study published in Scientific Reports identified a greater risk of depression among men who consumed significant amounts of sugar in their diet. Additionally, research indicates that sugar consumption often precedes the development of depression, rather than being a consequence of it.
Cognitive Function and Mood
The impacts of sugar consumption on mental health extend beyond just depression. A review of several studies has highlighted that high sugar intake can correlate with mild cognitive impairment in seniors and negatively affect children’s cognitive function. Rats experienced cognitive problems and inflammation in the brain after starting a high-sugar diet for just 5 days.
Incorporating a healthful diet low in refined ingredients like sugar but high in omega-3 fatty acids, vitamins, and minerals may be beneficial for individuals experiencing depression. Studies have shown that these dietary changes can support improved mental wellbeing.
« Consumption of processed and fast food was found to be higher in individuals with increased rates of depression. »
By making conscious choices to limit added sugars and opting for whole, nutrient-dense foods, we can take an important step towards supporting our mental health and cognitive function. The Dietary Guidelines for Americans, 2020-2025, suggest limiting added sugars to less than 10% of daily caloric intake – a recommendation that may have far-reaching benefits for our overall wellbeing.
Children’s Added Sugar Consumption
The alarming reality is that children are consuming far too many added sugars in their diets. On average, children aged 2-19 years old are taking in about 17 teaspoons of added sugar per day, which is much higher than the recommended limit of less than 10% of total daily calories.
The impact of this excess sugar consumption on childhood health is significant. Numerous studies have linked it to weight gain, obesity, type 2 diabetes, and other concerning health problems. It’s crucial for parents to be mindful of their child’s intake of sugary foods and beverages to support their overall well-being and development.
Sources of Added Sugars in Children’s Diets
Research shows that the primary sources of added sugars in children’s diets are often bakery products, sugar-sweetened beverages, and fruit juices. These foods and drinks can quickly add up to exceed the recommended limits, putting children’s health at risk.
- Bakery products, such as cakes, cookies, and pastries, have been identified as a major contributor to free and added sugar intake among preschool-aged children.
- Sugar-sweetened beverages, including soda, sports drinks, and even 100% fruit juices, have been linked to increased cardiometabolic risk factors in young children.
- Consumption of sugar-sweetened beverages in infancy has been associated with a 13% increased risk of being overweight at 8 years of age.
Dietary Guidelines for Added Sugar Intake
The Dietary Guidelines for Americans recommend limiting added sugars to less than 10% of total daily calories. However, the reality is that the majority of school-aged children, approximately 70-80%, currently exceed this recommended limit.
In response, the U.S. Department of Agriculture (USDA) has established product-based limits for added sugars in school meals, to be implemented by the 2025-26 school year. This includes a limit of 6 grams of added sugars per dry ounce for breakfast cereals and no more than 12 grams of added sugars per 6 ounces for yogurt.
Furthermore, the USDA plans to implement a weekly dietary limit on added sugars across the school lunch and breakfast programs by the 2027-28 school year, ensuring that added sugars account for less than 10% of calories throughout the week.
By taking these steps to reduce added sugar consumption in children’s diets, the USDA aims to promote better health and academic performance among school-aged individuals. Empowering parents and caregivers to make informed choices is also crucial in addressing the added sugar intake in children and its impact on childhood health.
Conclusion
The risks associated with consuming too many foods and drinks high in added sugars are clear – from weight gain and obesity to type 2 diabetes, heart disease, certain types of cancer, acne, skin aging, and even mental health issues like depression. It’s crucial for people of all ages to take a closer look at their sugar intake and make informed choices to prioritize long-term health and wellbeing.
By limiting consumption of candy, sweetened cereals, desserts, and sugary beverages, and instead choosing whole, minimally processed foods, individuals can go a long way in supporting their overall health. The recommended daily intake of added sugars is 100-150 calories, or 6-9 teaspoons, yet the average American consumes far more than that. Becoming more mindful of sugar sources and making conscious efforts to moderate intake can have a significant positive impact on one’s physical and mental well-being.
Ultimately, the evidence is clear – reducing added sugar in the diet is an important step towards improved health and longevity. With small, sustainable changes, individuals can take control of their sugar intake and enjoy the benefits of a balanced, nutrient-rich diet.
