Sugary Drinks (original) (raw)

Plastic bottles of assorted carbonated soft drinks in variety of colors

Sugary drinks (also categorized as sugar-sweetened beverages or “soft” drinks) refer to any beverage with added sugar or other sweeteners (high fructose corn syrup, sucrose, fruit juice concentrates, and more). This includes soda, pop, cola, tonic, fruit punch, lemonade (and other “ades”), sweetened powdered drinks, as well as sports and energy drinks.

As a category, these beverages are the single largest source of calories and added sugar in the U.S. diet. [1,2] In other parts of the world, particularly developing countries, sugary drink consumption is rising dramatically due to widespread urbanization and beverage marketing. [3]

How sweet is it?

There are 4.2 grams of sugar in a single teaspoon. Now, imagine scooping up 7 to 10 teaspoons full of sugar and dumping it into your 12-ounce glass of water. Does that sound too sweet? You may be surprised to learn that’s how much added sugar is in the typical can of soda. This can be a useful tip to visualize just how much sugar is in your drink. To get you started, we’ve prepared a handy guide to the amount of sugar and calories in popular beverages.

Aside from soda, energy drinks have as much sugar as soft drinks, enough caffeine to raise your blood pressure, and additives whose long-term health effects are unknown. For these reasons, it’s best to skip energy drinks. The guide includes sports beverages as well. Although designed to give athletes carbohydrates, electrolytes, and fluid during high-intensity workouts that last one hour or more, for everyone else they’re just another source of calories and sugar.

Drinks naturally high in sugar like 100% fruit juices are also featured. While juice often contains healthful nutrients like vitamins, minerals, and phytochemicals, it should also be limited as it contains just as much sugar (though from naturally occurring fruit sugars) and calories as soft drinks.

Sugary drinks and health

When it comes to ranking beverages best for our health, sugary drinks fall at the bottom of the list because they provide so many calories and virtually no other nutrients. People who drink sugary beverages do not feel as full as if they had eaten the same calories from solid food, and research indicates they also don’t compensate for the high caloric content of these beverages by eating less food. [4] The average can of sugar-sweetened soda or fruit punch provides about 150 calories, almost all of them from added sugar. If you were to drink just one of these sugary drinks every day, and not cut back on calories elsewhere, you could gain up to 5 pounds in a year. Beyond weight gain, routinely drinking these sugar-loaded beverages can increase the risk of type 2 diabetes, heart disease, and other chronic diseases. Furthermore, higher consumption of sugary beverages has been linked with an increased risk of premature death. [5]

Body weight and obesity

The more ounces of sugary beverages a person has each day, the more calories he or she takes in later in the day. This is the opposite of what happens with solid food, as people tend to compensate for a large meal by taking in fewer calories at a later meal. This compensatory effect doesn’t seem to be present after consuming soft drinks, for several possible reasons:

Dozens of studies have explored possible links between soft drinks and weight, and they consistently show that increased consumption of soft drinks is associated with increased energy (caloric) intake.

Alternatively, drinking water in place of sugary drinks or fruit juices is associated with lower long-term weight gain. [16]

Diabetes

People who consume sugary drinks regularly—1 to 2 cans a day or more—have a 26% greater risk of developing type 2 diabetes than people who rarely have such drinks. [17] Risks are even greater in young adults and Asians.

Strong evidence indicates that sugar-sweetened soft drinks contribute to the development of diabetes.

Heart disease

Gout

A 22-year-long study of 80,000 women found that those who consumed a can a day of sugary drink had a 75% higher risk of gout than women who rarely had such drinks. [24] Researchers found a similarly-elevated risk in men. [25]

Bone health

Soda may pose a unique challenge to healthy bones:

Liver cancer

Results from a Women’s Health Initiative study following 98,786 postmenopausal women (ages aged 50 to 79) for about 20 years found that participants who drank the highest amounts of sugar-sweetened beverages (SSB) had an increased risk of liver cancer. More specifically, those drinking 1 or more servings of SSB daily had an 85% higher risk of liver cancer than those who drank 3 or fewer servings of SSB per month. The participants used questionnaires to self-report their intakes of SSB (including soda and fruit drinks but not fruit juice) and diagnosis of liver cancer. The researchers also examined intakes of artificially sweetened beverages, comparing higher intakes of 1 or more servings per day with lower intakes of 3 or fewer servings per month, but did not find any association with liver cancer. [27]

Mortality

According to a large, long-term study of 37,716 men and 80,647 women in the U.S., the more sugary beverages people drink, the greater their risk of premature death — particularly from cardiovascular disease, and to a lesser extent from cancer. [5]

Another long-term study of 18 years from the Nurses’ Health Study and Health Professionals Follow-up Study also found that sugary beverages were linked with a higher risk of premature death in more than 15,000 men and women with type 2 diabetes. [28] It found an increased risk of early death from any cause as well as a higher incidence of cardiovascular disease (CVD) and premature deaths from CVD. Replacing sugary beverages with artificially sweetened beverages was associated with a significantly lower risk of CVD incidence and early death in adults with diabetes, even after controlling for weight changes.

Results from a Women’s Health Initiative study following 98,786 postmenopausal women (aged 50 to 79) for about 20 years found that participants who drank the highest amounts of sugar-sweetened beverages (SSB) had an increased risk of death from chronic liver diseases like nonalcoholic fatty liver disease, cirrhosis, chronic hepatitis, and fibrosis. [27] More specifically, those drinking 1 or more servings of SSB daily had a 68% higher risk of death from chronic liver disease than those who drank 3 or fewer servings of SSB a month. The participants used questionnaires to self-report their intakes of SSB (including soda and fruit drinks but not fruit juice) and diagnosis of chronic liver disease. The researchers also examined intakes of artificially sweetened beverages, comparing higher intakes of 1 or more servings per day with lower intakes of 3 or fewer servings per month, but did not find any association with deaths from chronic liver disease.

Sugary drink supersizing and the obesity epidemic

There is sufficient scientific evidence that decreasing sugar-sweetened beverage consumption will reduce the prevalence of obesity and obesity-related diseases. [29] Unfortunately, sugary beverages are a regular drink of choice for millions around the world, and a major contributor to the obesity epidemic.

Compounding the problem is that sugary drink portion sizes have risen dramatically over the past 40 years, leading to increased consumption among children and adults:

The role of sugary drink marketing

soda advertisment

Beverage companies spend billions of dollars marketing sugary drinks, yet generally rebuffs suggestions that its products and marketing tactics play any role in the obesity epidemic. [38]

Adding to the confusion, studies funded by the beverage industry are four to eight times more likely to show a finding favorable to industry than independently-funded studies. [39]

It’s also important to note that a significant portion of sugary drink marketing is typically aimed directly at children and adolescents. [40]

Cutting back on sugary drinks

When it comes to our health, it’s clear that sugary drinks should be avoided. There is a range of healthier beverages that can be consumed in their place, with water being the top option.

Of course, if you’re a frequent soda drinker, this is easier said than done. If it’s the carbonation you like, give sparkling water a try. If the taste is too bland, try a naturally flavored sparkling water. If that’s still too much of a jump, add a splash of juice, sliced citrus, or even some fresh herbs. You can do this with home-brewed tea as well, like this sparkling iced tea with lemon, cucumber, and mint.

What about “diet” sodas or other drinks with low-calorie sweeteners?

Low-calorie sweeteners (LCS) are sweeteners that contain few to no calories but have a higher intensity of sweetness per gram than sweeteners with calories. These include artificial sweeteners, such as Aspartame and Sucralose, as well as extracts from plants like steviol glycosides and monk fruit. Beverages containing LCS sometimes carry the label “sugar-free” or “diet.” The health effects of LCS are inconclusive, with research showing mixed findings. A 2018 scientific advisory by the American Heart Association and American Diabetes Association noted that further research on the effects of LCS beverages on weight control, cardiometabolic risk factors, and risk of cardiovascular disease and other chronic diseases is needed. That said, they also note that for adults who are regular high consumers of sugary drinks, LCS beverages may be a useful temporary replacement strategy to reduce intake of sugary drinks.

Learn more about the research on LCS in foods and beverages.

Action beyond the individual level

Warning against drinking sugary beverages

Reducing our preference for sweet beverages will require concerted action on several levels—from creative food scientists and marketers in the beverage industry, as well as from individual consumers and families, schools and worksites, and state and federal government. We must work together toward this worthy and urgent cause: alleviating the cost and the burden of chronic diseases associated with the obesity and diabetes epidemics in the U.S. and around the world. Fortunately, sugary drinks are a growing topic in policy discussions both nationally and internationally. Learn more about how different stakeholders can take action against sugary drinks.
