Mr. Sharma doesn’t add sugar to his tea, thinking it will help keep his blood sugar in control. But he drinks milk tea five times a day. Then he wonders…” Why isn’t my sugar under control?”
The reason is, regular tea contains milk, which contains lactose (a natural sugar) that can raise blood sugar levels.
In such a case, replacing your regular milk tea with green tea could be a smart decision. Not only does it help in maintaining blood sugar levels, but green tea also has some additional health benefits. Stay tuned to know more in detail.
How Does Diabetes Work?
Whenever you eat roti, rice, or any carbohydrate-rich food, it breaks down in the body and turns into glucose (sugar). To transport this glucose to the cells, the pancreas releases a hormone, which is called insulin. Insulin’s job is to move sugar from the blood circulation into cells to be used for energy.
But in diabetes, this entire process is disturbed.
In Type 2 DM, the body produces insulin, but the cells resist it. This condition is called insulin resistance. Over time, the pancreas stops or reduces insulin production. As a result, blood sugar remains high and doesn’t stay under control.
Type 1 Diabetes is an autoimmune condition. In this, the body’s immune system mistakenly destroys the cells that produce insulin. Because of this, the body is unable to produce any insulin at all.
Green Tea and Type 2 Diabetes: What Does Science Say?
Green tea has always been an important part of Ayurveda and Asian cultures, but now modern science has also begun to recognize how useful it can be in diabetes, especially Type 2 diabetes.
Green tea is a type of tea made from the leaves of the Camellia sinensis plant. The same plant from which black tea is made. The only difference is that while making green tea, the leaves undergo a special quick-drying process so that their natural nutrients and antioxidants are preserved. In black tea, the leaves are more heavily processed, which causes some of those antioxidants to be lost.

Green tea may taste a little bitter, but it contains several powerful health-supporting elements like catechins, a type of natural antioxidant. These compounds help repair internal damage, reduce inflammation, and support metabolism.
It also contains caffeine, but much less compared to coffee or black tea. That’s why it can give you a mild energy boost without making you feel too jittery.
Some experts say that green tea can also help improve your gut health, like supporting the “good bacteria” inside the gut, and helping control leaky gut and gut inflammation. When the gut works properly, insulin functions better too, and blood sugar doesn’t spike as much.
Apart from that, green tea contains L-theanine, a special amino acid that calms the brain, but some studies also suggest that it might help with glucose uptake or slightly improve fasting sugar and HbA1c.
However, till now, most studies done on green tea and diabetes have mainly focused on Type 2 diabetes, because it is the most common type.
Benefits of Green Tea for People with Type 2 Diabetes
1. Blood Sugar Control
Green tea may help your body use insulin more effectively, which helps prevent blood sugar levels from spiking too much. Some researchers even believe that if you drink green tea regularly, it may reduce the risk of developing Type 2 diabetes.
In one Japanese study, it was found that people who drank green tea regularly for 7 years had a significantly lower chance of developing diabetes.
A large-scale research study in China (with over 500,000 people) showed that those who drank green tea daily not only had a lower risk of diabetes, but if they already had diabetes, their risk of complications was also reduced.
2. Weight Management
Maintaining a healthy weight is undoubtedly important for managing diabetes. Green tea might help a bit in this area, though research is mixed.
The polyphenols in green tea are believed to boost metabolism and reduce fat absorption. Some studies have shown that this can support weight loss.
3. Support for Heart Health
Having diabetes increases the risk of heart disease. That’s why protecting heart health is also important. Some research studies say that green tea may help reduce LDL (bad cholesterol) and improve total cholesterol levels.
A meta-analysis (a combined review of 5 different studies involving over 600,000 people) found that drinking 2–4 cups of green tea daily could reduce stroke risk by 21–24%.

One theory suggests that the flavonoids in green tea help relax blood vessels, which allows smoother blood flow and lowers pressure. Some other research also suggests that green tea may help lower high blood pressure, especially when consumed regularly.
4. Helps Reduce Inflammation
In Type 2 diabetes, chronic inflammation is a hidden enemy. It disturbs your insulin signals and makes sugar control harder.
The anti-inflammatory effects of green tea seem quite promising, but research on this is still somewhat limited. Experts say the body’s immune response is quite complex, and every inflammatory marker behaves differently. So it’s hard to say that green tea will have the same effect on everyone.
But one recent finding does suggest that green tea may help reduce gut inflammation (which affects both diabetes and immunity). When your gut functions well, metabolism and sugar control also tend to be smoother.
How to Include Green Tea in Your Routine the Right Way (Especially If You Have Diabetes)
If you’re dealing with prediabetes or type 2 diabetes, adding green tea to your routine can be a smart step. But you’ll get the maximum benefit only when you consume it regularly and in the right way.
Try to Drink Green Tea Daily
Experts say that the catechins in green tea (the compounds responsible for most of its benefits) are not absorbed very well by the body and get flushed out quickly. That’s why drinking just one cup won’t do much. You need to take small doses throughout the day so that the effect stays consistent.
But that doesn’t mean the more you drink, the better. While too much green tea generally doesn’t harm a healthy person, if you’re sensitive to caffeine, it might cause issues like dizziness, trouble sleeping, or anxiety.
Drinking 2–4 cups could be an ideal amount, enough for benefits and with a low risk of side effects.
Brew Green Tea The Right Way for Maximum Benefits
The way you make green tea also matters. Not all green teas are the same, but what’s most important is water temperature and steeping time. Don’t use fully boiling water. Let it cool slightly to around 185°F (85°C) is ideal for extracting catechins properly.
Steeping time, 3 minutes, is considered best. Steeping for longer can make the taste bitter and degrade some of the catechins. Once brewed, don’t leave the tea sitting for more than an hour, as the antioxidants start to break down after that. You can use either teabags or loose leaves, both are fine. But if you want fresher flavor and slightly more benefits, consider trying matcha green tea.
Make The Most Of Your Green Tea
One common mistake is that people think they’re doing something healthy by drinking green tea, but then add sugar, milk, or flavored syrups, which can negatively affect blood sugar levels.
Matcha lattes, green tea boba drinks, or many commercial “green tea” products often contain a lot of sugar and fat. These kinds of drinks are not beneficial for diabetes; they might even have the opposite effect. The best way is to keep your tea plain- no sugar, no milk, no artificial flavors. If the bitterness bothers you, you can add a touch of tulsi (holy basil), lemongrass, or mint for natural flavor.
Remember, green tea is not a magic drink. If your diet is poor or you lead a sedentary lifestyle, don’t expect a big change from just drinking green tea. It’s a support tool, not a replacement.
