Sugary soft drinks: a top contributor to poor health
It comes as little surprise that soda and other sugar-sweetened beverages (SSBs) are consistently ranked among the unhealthiest things to drink. A single 12-ounce can of cola can contain up to 10 teaspoons of added sugar, far exceeding the daily recommended limit. The Centers for Disease Control and Prevention (CDC) notes that the excessive intake of added sugars is strongly linked to weight gain, obesity, and an increased risk of type 2 diabetes and heart disease. The body metabolizes the high-fructose corn syrup and other sweeteners in these drinks, which can lead to negative metabolic effects and a spike in blood sugar.
Beyond weight-related issues, the acidity in these beverages can also cause tooth enamel erosion and dental decay. This is compounded by the fact that SSBs offer little to no nutritional value, providing only empty calories that don't satisfy hunger, potentially leading to overconsumption of calories throughout the day.
The surprising dangers of energy drinks
Energy drinks often contain even higher levels of caffeine and sugar than standard sodas, making them a more significant health risk. Beyond the sugar crash, the high levels of stimulants like caffeine and guarana can have severe impacts on the cardiovascular and nervous systems.
Excessive consumption of energy drinks is linked to a range of side effects, including:
- Increased heart rate and palpitations: The high stimulant content can lead to heart rhythm disturbances and elevated blood pressure.
- Anxiety and restlessness: The combination of high caffeine and sugar can trigger anxiety, jitters, and insomnia.
- Dependency and addiction: Regular use can lead to dependency, and withdrawal can cause headaches, fatigue, and irritability.
- Dangerous mixers: Mixing energy drinks with alcohol is particularly risky, as the stimulants can mask the effects of intoxication, increasing the likelihood of binge drinking and other risky behaviors.
The hidden sugars in 'healthy' options
Many consumers believe they are making a healthier choice by opting for bottled iced teas, juices, or sweetened coffee drinks. However, these options are often just as problematic. Pre-packaged iced teas can be loaded with the same amount of sugar as soda. Similarly, coffee shop Frappuccinos and flavored lattes can contain a combination of high sugar content and saturated fat, which has been shown to drive up insulin levels and promote fat storage.
Fruit juices are another deceptive product. While 100% fruit juice contains some vitamins, the process removes all the beneficial fiber. This results in a liquid that is high in natural sugar (fructose) and calories, which can lead to blood sugar spikes similar to soda. Without the fiber to slow absorption, the sugar is processed quickly by the body.
The debate over diet beverages
Diet sodas and other artificially sweetened drinks are often marketed as a guilt-free alternative to their sugary counterparts. While they don't contain sugar or calories, emerging research suggests they are not without risk. Some studies indicate that artificial sweeteners can disrupt the gut microbiome, which is vital for overall health. Other research points to a potential link between long-term, daily use of artificial sweeteners and an increased risk of metabolic dysfunction, heart disease, and stroke. Moreover, their intense sweetness can overstimulate taste receptors, potentially making less sweet, wholesome foods like fruits and vegetables less appealing.
Comparing common beverages
| Feature | Sugary Soda | Energy Drink | Diet Soda | 100% Fruit Juice |
|---|---|---|---|---|
| Sugar Content | Very high added sugar (e.g., 10 tsp in a 12oz can) | Very high added sugar, often similar to soda | Zero calories from added sugar | High natural sugar (fructose), comparable to soda |
| Caffeine | Moderate to high, depending on the brand | Very high, often 2-8x more than soda | Varies; many contain caffeine | None |
| Stimulants | Minimal, primarily caffeine if present | High levels of caffeine, taurine, guarana, etc. | Minimal, typically only caffeine if present | None |
| Nutritional Value | Empty calories, no nutritional benefit | Very little to no nutritional benefit | No nutritional value | Some vitamins, but lacks fiber |
| Main Health Risk | Obesity, type 2 diabetes, heart disease, dental decay | Heart complications, anxiety, insomnia, addiction | Potential gut and metabolic disruptions, overstimulation of taste buds | High sugar load, weight gain, potential for blood sugar spikes |
Healthier choices for better hydration
Moving away from these unhealthy beverages is a crucial step toward better health. The good news is that there are many appealing and nutritious alternatives to quench your thirst and satisfy your taste buds.
- Plain water: Still the gold standard for hydration. Adding slices of fruit like lemon, cucumber, or berries can enhance the flavor naturally.
- Sparkling water: Offers the fizz of soda without the sugar. Be sure to choose plain or naturally flavored versions without added sugars or artificial sweeteners.
- Unsweetened tea: Whether hot or iced, green or black, unsweetened tea offers antioxidants and a flavorful alternative to sugary drinks.
- Coffee (in moderation): Unsweetened coffee, either hot or iced, can provide a caffeine boost without the added sugar and empty calories.
- Kombucha: This fermented tea contains probiotics that may support gut health and offers a satisfying fizz. Just check the label to ensure it's low in sugar.
Conclusion
While a single definitive answer to what is the unhealthiest thing to drink may vary depending on individual health and consumption patterns, the overall consensus points to sugar-sweetened beverages and energy drinks. These drinks are packed with empty calories, excessive sugar, and sometimes stimulants that can have serious and long-term consequences for your health, including increased risks of obesity, type 2 diabetes, and cardiovascular issues. Even seemingly healthier options like fruit juices and diet drinks carry their own set of risks. The best strategy is to prioritize plain or infused water, and opt for unsweetened teas or coffees to protect your long-term well-being.
