Blood Sugar Level of a Diabetic

In a normal healthy person, the blood sugar level is meant to be between 70-110mg/dl. For a pre-diabetic, blood sugar level rises to above 150mg/dl. But for a diabetic, blood sugar is above 200mg/dl.

A diabetic cannot process sugar to energy, and thus sugar is retained in the blood. This condition is referred to as Diabetes Mellitus.

There are two main types of diabetes, Type 1 and Type 2, categorized based on the cause;

  • Diabetes Type-1 is caused by the body’s inability to produce enough insulin.

Insulin is a hormone that communicates with some body organs to store excess sugar. When the insulin produced by the pancreas is not sufficient to convert the body’s sugar, excess sugar is retained in the blood.

  • Diabetes Type-2 is the most common type of diabetes, making about 95% of all diabetes patients.

It results when the body does not respond to the insulin produced, hence leading to abnormally high blood sugar level.

This unbalanced blood sugar level can lead to the destruction of important body organs like the eyes in diabetes retinopathy, the heart and blood vessels. Hence, people with diabetes should work toward managing the condition by reducing their sugar intake, and taking drinks and medications that reduce their blood sugar level.

Peppermint tea is one of the few herbal teas that can affect blood sugar level. Although there have been only a little research to support this, it has been found that some compounds contained in peppermint tea reduce blood sugar level.

How Can Peppermint Tea Affect Blood Sugar Level?

Peppermint, as earlier said, contains numerous antioxidants responsible for its health benefits. Among these, polyphenols is note-worthy, as research has shown that its intake reduces the blood sugar level of its consumer. Though Peppermint is not the only plant with this organic compound, a 2010 study identifies dried peppermint as the second in 100 food richest in polyphenols, containing about 11900mg of polyphenols. In order words, peppermint is considered one of the richest in this “healing” compound.

Polyphenols have proven to help treat both acute and chronic ailments including obesity, cardiovascular diseases and diabetes. For that reason, it has been of recent a major topic of interest to nutritionist due to its many health benefits.

What are Polyphenols?

Polyphenols refer to a group of organic compounds found in natural herbs and plants. Polyphenols is a group of antioxidants divided into two main classes which is flavonoids and non-flavonoids.

Flavonoids are divided into

  • flavones,
  • flavonols,
  • isoflavones,
  • anthocyanin and
  • catechins.

Anthocyanins and catechins, according to research, are the polyphenols responsible for reducing the blood sugar level. They work to reduce the blood sugar level by improving insulin resistance.

Insulin resistance is responsible for diabetes type-2. In this case, target cells in the liver, muscles and fat cells do not respond well to insulin. As a result, sugar is not converted and stored. Polyphenols acts directly on this insulin, activate it and makes the target cells more receptive.

What Research Say?

A 2020 study on the effects of polyphenols on insulin resistance in the department of nutrition, dietetics and food has revealed the effectiveness of polyphenols in managing diabetes mellitus.

The human intervention studies on volunteers showed that the known subclass of the polyphenols effective in improving insulin resistance was Catechin-containing food and Anthocyanin, which are all present in peppermint tea. In our diets and teas, catechins and anthocyanins are absorbed in the small intestines, transported into the blood from there and then to target cells of the liver, muscles and fat where it exerts its effect.

Tip: Peppermint oil is one of the Essential Oils, just like Eucalyptus Oil.

Studies have also shown that individuals who take flavonoids, an antioxidant contained in peppermint, have a lower risk of developing type-2 diabetes. And although the mechanism to which polyphenols improves insulin resistance is still not clear, it is a fact that the intake of polyphenols in the diet is effective in improving insulin resistance and reducing blood glucose level.

However, more research need to be carried out in order to give proper dietary advice and prevent metabolically-induced complications.

Is Peppermint Tea Good for Diabetics?

Apart from activating insulin and improving insulin resistance, there are some other ways diabetics can benefit from this tea.

Peppermint as a tea is good for rehydrating the blood. According to research, dehydration could adversely increase the risk of diabetics. And so, one of the ways of constantly managing diabetes is by constant rehydration, with water or tea.

The European Food Safety Authority recommends 1.6-2.0 liters of water a day for diabetics. More so, an interesting alternative to water is peppermint tea due to its sweet and refreshing taste.

When the blood sugar level is high, the body searches for alternatives to rehydrate the blood and thus, makes use of body fluids like saliva and tears. This would further lead to complications like diabetic ketoacidosis, diabetic coma and even death. But like water, peppermint tea can help to dilute excess sugar in the blood of a diabetic which the body passes out as urine.

Furthermore, drinking calories free beverage is another important way of managing diabetes. For a diabetic, sugar-containing drinks will only increase risk and cause organ damages. But the intake of unsweetened herbal teas like peppermint tea will give the needed refreshment and as well manage the ailment.

More so, diabetes can alter the metabolism of fat and sugar in the body, thus causing indigestion. The intake of peppermint tea daily, however, can aid digestion of fatty food by increasing bile production in the liver.

Damage to the nervous system by diabetes could also lead to nausea, vomiting and constipation, which, of course, is discomforting to patients. This condition is called Gastroparesis. And it’s a symptom of diabetes. It’s characterized also by bloating and abnormal pain which could be helped treated effectively with peppermint tea.

When is Peppermint Tea Bad to Diabetics?

So much as peppermint tea is one of the best choices for a diabetic, it must be moderately drunken. It is recommended that 2-3 cups per day (maximum) is needed to reap the benefits. Drinking too much of peppermint tea could pose adverse effects to its consumers.

Furthermore, peppermint tea is recommended to be taken unsweetened by diabetic patients. It remains a task to control their sugar intake so as to keep their blood sugar level in check. And so, for this tea to be effective in controlling diabetes, it must be taken unsweetened, without sugar or any form of sweetener.

More so, it is important that before peppermint tea is consumed from its tea bag, its content is duly checked and approved by medical personnel. It is a known fact that some herbs have the ability to alter medications. And so if the tea bag contains such ingredients that alters the medication of a diabetic patient, it would rather be of harm to the patient.

Furthermore, a lot of patients while growing these herbs in their gardens would prefer to make these tea themselves. Still, there are ways with which these tea leaves could be prepared which would alter its components and make it useless or harmful to the body, and so, it is best to stick to recommended and healthy ways of preparing this tea, so as to retain its nutrients and flavor.

Certainly, oolong tea will contain the same constituents as black tea since it’s made from the same leave, and it will provide equal benefits as black tea. However, Oolong is said to have an additional benefit, it strengthens the tooth enamels which is due to the fluoride it contains.
