Is Green Tea Good for Diabetics

Last updated on August 3rd, 2023

Have you ever wondered if the steaming Cup of green tea you enjoy every morning could have more benefits than just waking you up? Green tea has been used for decades and is well-recognized for its considerable health benefits. Today, we’re diving into the fascinating topic of the effect of green tea on diabetes.

This delightful beverage seems to have everything from aiding in weight loss to boosting brain function. But what about its impact on diabetes? Is green tea suitable for people with diabetes? So, let’s start exploring the potential link between green tea and diabetes.

What is Diabetes?

Diabetes is also inferred as hyperglycemia, a continual metabolic disorder marked by high sugar levels. It happens when the body cannot use the insulin it generates or make enough of it. The pancreas secretes insulin, the hormone which aids in curbing blood glucose (sugar) levels.

Type 1 & Type 2 kinds are the most common variants of diabetes. In type 1, the body’s immune system mistakenly strikes down the pancreas’s cells which release insulin. It is an autoimmune disease. Therefore, due to this, significantly less or no insulin is secreted.

As a result, this raises sugar levels. Naturally, Type 1 diabetes occurs majorly in childhood or adolescence. And in this situation, one gets dependent on insulin for a lifetime. The bulk of cases of diabetes are of the second type, which is Type 2. The body cultivates an opposition to insulin’s effects, or the pancreas cannot create ample insulin to meet the body’s necessities.

Obesity, a passive lifestyle, a poor diet, and hereditary ties are the top risk factors for type 2 diabetes. Changing one’s lifestyle to include a nutritious diet, frequent exercise, and occasionally medication or insulin therapy can help control type 2 diabetes.

What is Green Tea?

Green tea is a type of tea renowned for its multiple health benefits and fascinating flavour. It is extracted from the Camellia sinensis plant, similar to black tea & oolong clove tea. However, unlike its counterparts, green tea undergoes minimal oxidation during processing.

The distinctive feature of green tea lies in its preservation of natural compounds and vibrant green colour, achieved by promptly heating or steaming the freshly picked leaves. This minimal oxidation process produces a light flavour profile with a subtle, grassy, or vegetal taste. The popularity of green tea stems from its rich content of beneficial compounds, such as catechins and polyphenols, which act as antioxidants in the body.

These antioxidants are fundamental in protecting our cells from free radicals. Some studies have indicated that green tea may offer potential health advantages, including improved heart health, a boosted metabolism, and support for weight loss. But is green tea good for diabetics?

Besides its potential health benefits, green tea is valued for its calming properties on sugar levels. It has several compounds that affect blood sugar positively. It also includes L-theanine, the amino acid causing relaxation without inducing drowsiness. This aspect contributes to the perception of green tea as a soothing and rejuvenating beverage.

Green tea is available in various forms, including loose-leaf tea, tea bags, and powdered matcha, made by grinding green tea leaves. It can be enjoyed either hot or cold. There are flavoured varieties also available.
