Did you know?

What is Barley Tea and How is it Made? 

Roasted Barley Grains 

Barley tea owes its charm to roasted barley grains. Toss in some corn and you get a sweet twist. Barley is full of fiber as well as vitamins and minerals.  

The Process of Making Barley Tea 

Here’s how one brews barley tea. 

  • Roasting the grains 

Roasting is a key part. Heat raw barley till it turns deep brown. This draws out its full flavour. It also reduces the acrylamide in the tea. 

  • Brewing the tea 

Steeping comes next. You steep the roasted grains in hot water for 5 to 10 minutes. Once done, pour out the tea and enjoy it hot or cold. 

Nutrition Profile of Barley Tea 

It’s not packed with carbohydrates or calories. However, it’s full of vitamins, minerals, and antioxidants. 

Macronutrients 

  • Low in calories 

The low-calorie content is a salient feature of barley tea. The exact number depends on how it’s brewed. Yet it is a solid pick if you want to keep control on sugar intake. 

  • Carbohydrates and fiber 

Barley has plenty of fiber and carbohydrates. Keep in mind, when brewing, most of these nutrients stay in the grains. They don’t leach into the tea. 

Micronutrients 

  • Vitamins and minerals 

The tea boasts a mix of B vitamins, iron, zinc, and manganese. One thing we still don’t know exactly is how much seeps into the tea during brewing.  

  • Antioxidant content 

Antioxidants are a big deal in barley tea. They shield cells from the harms of free radicals. Some of these key antioxidants are chlorogenic and vanillic acids, and quercetin. 

Potential Health Benefits of Barley Tea 

Drinking barley tea often is good for you. The antioxidants may lower the risk of certain health issues. It may help to rein in cholesterol and blood sugar levels. Besides that, it could play a role in weight loss as well. 

1. Antioxidant-rich 

  • Role in reducing oxidative stress 

One huge benefit of barley tea is that it’s loaded with antioxidants. They work hard to combat harmful radicals. They shield our cells from damage, which could help to boost immunity. 

2. Possible Anti-Cancer Properties 

In some studies, certain substances in barley tea showed anti-cancer effects. Still, we need more studies to confirm this. It’s exciting to know that eating whole grains like barley may potentially reduce cancer. These include ferulic acid and quercetin. They are proposed to block tumours from growing and stop cancer cells from spreading. 

3. Lowers Cholesterol Levels 

  • How it works? 

There’s something in barley called tocols. They might reduce LDL (bad) cholesterol levels. This means healthier hearts. The antioxidants in barley tea also help keep our hearts well. 

Some studies point to barley reducing cholesterol levels. For example, a review of trials found that barley did lower total and LDL cholesterol. But things varied amongst the trials. Therefore, more research is required in this aspect.  

4. Controls Blood Sugar 

  • Role in regulating blood sugar levels 

Unsweetened barley tea may help control blood sugar. Barley is said to increase levels of a gut bacteria called prevotella. This microbe can lead to better blood sugar control. 

Review studies found that barley foods may reduce blood sugar spikes after meals. Also, having antioxidants may aid in improving how well people cope with diabetes, but further studies are needed in regard. 

5. Aids in Weight Loss 

  • How it supports weight loss 

Barley tea’s lack of calories and fiber content may aid weight loss. Feeling full is key to fighting off hunger. Barley, is said to make you feel full longer. 

  • Research on its effects on weight management 

One study found that barley reduces body weight and fat. This may be probably due to its high fiber content and slow digestion.  

Potential Risks and Side Effects of Barley Tea 

Sadly, there are some risks linked to barley tea. 

Allergic Reactions 

Some could be allergic to barley. This could lead to skin rashes, upset stomach, or headaches. 

Interactions With Medications 

Barley tea might react with some medications. It’s always wise to ask your doctor when starting any new food or supplement. 

Overconsumption 

As the saying goes, “too much of a good thing can be bad”. Too much tea could lead to stomach issues. Remember, the fiber content is high. So, watch your intake. 

How to Prepare Barley Tea and Where to Buy? 

Preparing Barley Tea From Scratch 

  • Selecting and roasting barley 

Start with raw barley. Heat it on medium heat till it turns deep brown. Roasting also reduces acrylamide. 

  • Brewing the tea 

Use 3 to 5 tablespoons of roasted barley. Add it to 8 cups of water. Brew for 5 to 10 minutes. Strain and serve hot or cold. 

Buying Prepackaged Barley Tea 

  • Convenience and availability 

People who are short on time opt for prepackaged barley tea. You’ll find them at specialty stores, Asian grocers, or online. 

  • Recommendations for choosing quality barley tea 

Check the labels when you’re buying pre-packaged barley teas. Avoid the ones high in sweeteners. Make sure no allergens are listed. And finally, pick those with deeply roasted barley. 

Conclusion 

Barley tea has a lovely flavour. Its potential health benefits are antioxidant properties, aiding in managing cholesterol, and controlling blood sugar. It’s also light on calories. Of course, there are risks. But these are minor if you drink wisely and make sure to keep your doctor in the loop before incorporating it into your daily routine. Whichever way you go, homemade or store-bought barley tea may be a healthy addition to your day-to-day drinks.
