11 Low-Sugar Drinks That Won’t Spike Your Blood Sugar

Sure, you can drink diet soda and sugar-free juice, but plenty of other drink options are low in sugar and come with added health benefits. 

1. Tea

Whether it’s hot or cold, there is no shortage of choices when it comes to tea. There are so many different varieties and flavors available, both caffeinated and caffeine-free. Green Tea is popular for its many health benefits. Whether you like hot or iced tea, opt for unsweetened varieties or add artificial sweeteners like stevia or monk fruit. 

Nutritional Facts

Tea is full of antioxidants, which help the body fight oxidative stress from free radicals. Many teas include important minerals such as copper, manganese, iron, zinc, magnesium, calcium, sodium, and potassium.

2. Kefir

This milk-derived probiotic-rich drink supports gut health and comes in unsweetened and low-fat varieties. Packed with beneficial bacteria, kefir adds a tangy twist to your beverage repertoire. Kefir is also a good source of protein, calcium, and other minerals. 

Nutritional Facts:

One serving (250ml) of whole milk kefir contains approximately:

  • 145 calories
  • 8.3g protein
  • 7.5g fat
  • 11g carbs
  • 333mg calcium
  • 28mg magnesium

4. Coffee

Black Coffee, whether hot or cold brew, is a low-calorie, sugar-free option. It provides a caffeine boost without the added sugars found in flavored coffee drinks. If you prefer sweeter coffee, you can add a natural sugar substitute like stevia. 

You may have heard that coffee can dehydrate you because it’s a diuretic. While the caffeine in coffee does cause your body to pass more urine, these effects are too mild to cause dehydration, especially if you're a regular coffee drinker. Coffee may even be hydrating for some people because it contains a lot of water.

Nutritional Facts

Coffee contains many micronutrients, including riboflavin (vitamin B2), niacin (vitamin B3), magnesium, potassium, various phenolic compounds, and antioxidants.

5. Sparkling Water

For those who crave the fizz without the sugar, sparkling water is a bubbly delight. Enhance it with a splash of fresh lemon or a few mint leaves for added flavor. Drinking sparkling water has no negative health risks, but it has no particular health benefits either. It may cause bloating and gas in some if consumed in excess.

  • Cucumber and Mint
  • Apple and Cinnamon
  • Blackberry and Orange

7. Fresh Juice

When you drink Fresh Juice, your body can absorb nutrients quickly without digesting fibers and other components in whole foods. This can help you increase your intake of vitamins and minerals.

Opt for freshly squeezed fruit juice from whole fruits to avoid added sugars. Experiment with different combinations like orange and berry for a naturally sweet and nutritious treat.

Nutritional Facts

The nutritional value of fresh juice will depend on the fruit or vegetable it comes from. Generally, fresh juice is high in vitamins and minerals and will have some calories and some natural sugar.

  • 0 grams fat

9. Kombucha

This fermented tea packs a punch of flavor without excessive sugar. It’s packed with probiotics, promoting a healthy gut microbiome and aiding digestion. The beverage's antioxidant properties contribute to reduced inflammation and support cellular health. Choose varieties with no added sweeteners for a gut-friendly, low-sugar option.
