Some energy drinks can give your blood glucose an unhealthy jolt. Choose one of these healthier options instead.
Energy drinks are a popular alternative for people who don’t like coffee or want something different pre-workout, or to perk up after their morning joe. But they can come with a metabolic cost.
First, they’re often loaded with sugar. One popular brand packs 63 grams of added sugars in a 16-ounce can—that’s nearly 16 teaspoons.
And low-sugar and sugar-free versions may not be much better. Many sugar-free options use artificial sweeteners, such as sucralose and acesulfame potassium, which may raise the risk of insulin resistance. Moreover, some energy drinks contain harmful additives, such as food dyes and preservatives.
Finally, if you rely on energy drinks regularly to stay focused or boost energy levels, you may want to look closely at your diet and lifestyle habits. Eating high-glycemic meals can cause a blood sugar crash, leaving you feeling drained and sluggish, whereas choosing blood sugar-friendly foods will give you a consistent energy supply.Sleep andexercise are other key lifestyle factors influencing your energy (and glucose) levels throughout the day.
Here’s how to find no-sugar, healthy energy drinks that taste great and live up to their name, plus our favorite picks.
How to Find a Healthier Energy Drink
With the energy drink market totaling more than$19 billion in sales last year compared to $12 billion five years ago, there’s no shortage of options in any mini-mart or grocery store. Some of these drinks have slick marketing and wellness-oriented or healthy-sounding claims, so it’s important to examine the nutrition label and ingredient list carefully. Here’s what to look for when shopping for a healthier energy drink:
1. Keep tabs on the caffeine content. Many energy drinks get some of their get-up-and-go from caffeine, the stimulant found in coffee and tea.Research suggests that caffeine is associated with impaired glucose metabolism and reduced insulin sensitivity in the short term. However, no concrete proof shows that caffeine intake harms metabolic health over the long run. In fact,one study showed that people with high caffeine concentration in their blood plasma (a marker of long-term caffeine consumption) had lower body mass indexes and a reduced risk of Type 2 diabetes. Experts speculate that caffeine may rev up fat metabolism and increase the amount of energy you burn throughout the day.
The problem is that energy drinks can deliver anywhere from 50 to more than 400 milligrams of caffeine per serving. TheFDArecommends getting no more than 400 mg daily—the amount in four to five eight-ounce cups of coffee. The amount of caffeine that you can tolerate depends on various factorssuch as genetics, medications (such as oral contraceptives), and lifestyle factors (such as smoking). Too much caffeine may lead to the jitters, yes, but also to sleep problems, nausea, anxiety, and increased blood pressure.
It doesn’t matter if that caffeine comes from a natural or synthetic source. When it comes to the actual molecule, natural and synthetic caffeine are virtually identical. The difference is that synthetic caffeine is made in a lab, while natural caffeine is derived from plant-based sources, such as green tea, yerba mate, guarana, and green coffee. Although many manufacturers tout that “all-natural caffeine” is healthier, both types have the same effect on your body.
2. Avoid added sugars and artificial sweeteners.Some of the most popular brands of energy drinks contain anywhere from27 to63 grams of added sugars per can. The Dietary Guidelines for Americans’ recommended sugar limit is less than 10 percent of daily calories (i.e., 50 grams for someone on a 2,000-calorie diet). Still, the truth is you don’t need any added sugar in your diet. Sugar is one of the worst foods for metabolic health because too much can cause glycemic variability that can drive cellular damage, increase inflammation, and raise the risk of obesity, Type 2 diabetes, and heart disease.
Sugar-free energy drinks seem healthier, but some contain artificial sweeteners, including sucralose, acesulfame potassium, and aspartame. These sweeteners may cause unfavorable changes in the gut microbiome. They may increase insulin production and, in turn, the risk of insulin resistance. Instead, look for drinks with natural sweeteners, such as stevia, erythritol, and monk fruit, which don’t have the same metabolic side effects.
3. Steer clear of dyes, artificial colors, and preservatives.Some manufacturers use synthetic dyes, such as Red 40, Yellow 5, and Yellow 6, to give their drink a brighter hue.Other countries ban these ingredients because of their potential ties to ADHD and carcinogens. Additionally, energy drinks may contain chemical preservatives, such as sorbic acid and sodium benzoate, to prevent spoiling. While these ingredients are generally recognized as safe by the FDA, some research suggests that sodium benzoate maydisrupt hormones and increase inflammation in the body.
4. Consider the “extras.”Many energy drinks are infused with vitamins, minerals, electrolytes, supplements, and herbal extracts. Some common additions include taurine andcreatine (naturally occurring substances used in energy production), B vitamins, and herbs like ginseng and ginkgo biloba. Certain drinks also use plant extracts, such as yerba mate, green tea, and guarana, for their caffeine content. Some research suggests that these compounds may have metabolic health benefits. For instance,one study suggests that green tea extract may reduce inflammation in the gut and, in turn, protect against metabolic syndrome. While the FDA recognizes these ingredients as generally safe, there’s no regulating body to check that they’re effective and live up to the manufacturers’ claims.
5. Do a double take.When you’re grabbing an energy drink, check the label. Many brands offer versions with similar packaging but very different ingredients. For example, Guayaki Organic Sparkling Lima Limon has zero sugar, while itsOrganic Lemon Elation variety looks nearly identical—and contains 23 grams of sugar.
