Dietitians Reveal All

If you’re aiming to maintain stable blood sugar levels, you’re probably familiar with the importance of a diet rich in high-fiber foods, lean proteins, and complex carbohydrates while minimizing added sugars. However, what you might not have considered is that what you drink can also significantly impact your blood sugar. In this article, we’ll explore the best and worst drinks for blood sugar balance, as recommended by registered dietitians.

The Worst Drinks for Blood Sugar

1. Alcohol

Registered dietitian Sarah Schlichter, MPH, RDN, advises being extra cautious with alcohol consumption if you want to prevent blood sugar spikes. Alcohol can disrupt hormonal balance and reduce insulin’s ability to regulate blood sugar levels, leading to instability. Heavy beers and mixed drinks, which are high in carbohydrates, are particularly detrimental to blood sugar stability. If you are on medication to manage your blood sugar, alcohol consumption may also interfere with its effectiveness. To maintain stable blood sugar levels, it’s essential to avoid drinking on an empty stomach or when your blood sugar is low.

2. Sugary Beverages

Kiran Campbell, RD, another registered dietitian, and creator of Kiran Campbell Nutrition, highlights several sugary beverages that can wreak havoc on blood sugar levels. These include sodas, sweet teas, energy drinks, sports drinks, and drinks with fruit juice. These drinks are laden with added sugars, causing rapid spikes in blood sugar. To keep your blood sugar steady, it’s advisable to minimize or altogether avoid these sugary beverages.

The 2 Best Drinks To Lower Your Blood Sugar

Now that you’re aware of the drinks that can elevate your blood sugar, let’s explore the top two beverages recommended for blood sugar management.

1. Water

It may seem obvious, but water is a powerhouse when it comes to managing blood sugar levels. According to Campbell, a staggering 47 percent of Americans don’t consume enough water, which is crucial for blood sugar regulation. While water itself doesn’t impact blood sugar directly, it plays a vital role in preventing episodes of hyperglycemia by regulating hormones that affect glucose stability and urine production. Dehydration can lead to concentrated blood sugar, making proper hydration essential for overall health. Campbell emphasizes that regardless of your blood sugar level or medical conditions, water should be your beverage of choice.

2. Unsweetened Green Tea

Unsweetened green tea is a drink that can actually lower blood sugar levels. Scientific studies have shown that individuals who consume green tea experience improvements in glucose metabolism compared to those who consume decaffeinated coffee, black tea, or oolong tea.

The secret behind green tea’s blood sugar-lowering effect lies in its high content of epigallocatechin gallate (EGCG), a specific type of polyphenol. Research indicates a positive correlation between EGCGs and reduced blood sugar levels, making unsweetened green tea a valuable addition to your diet for managing the risk of Type 2 diabetes.

While no single food or drink can miraculously keep blood sugar low, a well-balanced diet is essential. When replacing sugary beverages like soda or sweet tea in your effort to manage blood sugar, unsweetened green tea is a smart choice. However, it’s important to remember that nothing can replace the importance of staying well-hydrated with good old H2O, regardless of how health-conscious your diet may be.


Maintaining stable blood sugar levels is vital for overall health and well-being. In addition to choosing the right foods, selecting the appropriate beverages can significantly impact your blood sugar. Avoiding alcohol and sugary drinks while prioritizing water and unsweetened green tea can contribute to better blood sugar management.
