Black Tea May Help Reduce Insulin Resistance
Black tea comes from the same plant as green tea, so as with green tea, youll reap diabetes-friendly benefits. Though it’s the same plant, different processing methods are used to create it, explains Stefanski.
A review published in June 2019 in the journal Antioxidants notes that some epidemiological studies show that drinking black, green, or oolong tea may reduce the risk of developing diabetes or diabetes complications. Plus, the researchers suggest tea may work in the body in part by improving insulin resistance, playing an insulin-like role, as well as alleviating the inflammatory response.
Also, black tea may work to help people with diabetes in other ways. Animal studies on black tea have found it may reduce carbohydrate absorption and therefore improve blood glucose control however, more research is needed on humans, explains Palinski-Wade. A review published in December 2016 in the journal Molecules found that black tea lowered body weight in animals.
Other research, published in January 2017 in the Asia Pacific Journal of Clinical Nutrition, found that drinking black tea after consuming sugar helped control blood glucose. The small study looked at people with prediabetes as well as people without diabetes.
More positive news for black tea drinkers: Another review found that tea drinkers, including those who drink black tea, had a lower prevalence of incidence of type 2 diabetes.

How Green Tea Affects Blood Pressure
Green tea contains caffeine about 35 milligrams per eight ounces of brewed green tea, according to the Center for Science in the Public Interest , so you might be wondering if green tea raises blood pressure.
Caffeine can raise your blood pressure temporarily. The small amount of caffeine in green tea may slightly raise blood pressure in those who already have high blood pressure and who are sensitive to caffeine, Angelone says. Caution may be warranted in these cases.
But otherwise healthy people may be in the clear. A February 2020 review of 24 trials in Medicine found that green tea or green tea extract significantly lowered systolic and diastolic blood pressure. The positive effects may be due to the catechins, or antioxidants, in green tea. However, researchers couldn’t pinpoint an optimal green tea dosage, and larger, longer-term trials are needed, the authors concluded.
And in an October 2014 meta-analysis of 25 randomized trials in the British Journal of Nutrition, short-term consumption of black or green tea didn’t appear to affect blood pressure. However, the researchers found that green tea consumption for at least three months helped lower both systolic and diastolic blood pressure, and even more so than black tea.
Additionally, green tea has a chemical called L-theanine that is known to help promote relaxation, Angelone says. That can help lower your blood pressure as opposed to stressful events, which can raise your blood pressure.

Special Precautions & Warnings
Pregnancy and breast-feeding: If you are pregnant or breast-feeding, green tea in small amounts – about 2 cups per day – is POSSIBLY SAFE. This amount of green tea provides about 200 mg of caffeine. However, drinking more than 2 cups of green tea per day is POSSIBLY UNSAFE. Consuming more than 2 cups of green tea daily has been linked to an increased risk of miscarriage and other negative effects due to the caffeine content. Also, green tea might increase the risk of birth defects associated with folic acid deficiency. In women who are nursing, caffeine passes into breast milk and can affect a nursing infant. Don’t drink an excessive amount of green tea if you are pregnant or breast-feeding.

Nitric Oxide And Green Tea
This is one of the bodys chief arterial-relaxing compounds, and is important for the health of veins as it may protect from atherosclerosis. One reason suggested is by lowering blood pressure, similar to the effects of sauna therapy and catechin antioxidants in matcha green tea .
These mechanisms are related to blood vessels ability to contract or relax in response to temperature, physical, and emotional stress.
- This is known as vascular-reactivity, and short-term studies have shown that drinking green tea may improve this metric .
- Its possible that this physiological mechanism may play a role in the late-onset of certain cardiovascular diseases with roots in emotionally tumultuous childhoods.
- Practices in adulthood which lower blood pressure may help.
Its also known that harmful levels of fats in the circulatory system may cause oxidative stress, and in turn arterial stiffening related to atherosclerosis. This state carries increased risk of blood clots and hypertension. Exercise and nutrition are thought to counteract these risks it’s also thought that an anti-inflammatory diet may encourage arterial health.
- The anti-inflammatory diet includes green tea, which may protect from arterial oxidative damage while lowering levels of bad cholesterol .
- Food or drink which helps blood vessels relax may improve the net benefits of exercise and healthy activity levels.

Tea Drinkers Reap Blood Pressure Benefits
Drinking a Half-Cup of Tea per Day Cuts Hypertension Risk in Half
Researchers found that men and women who drank tea on a daily basis for at least a year were much less likely to develop hypertension than those who didn’t, and the more tea they drank, the bigger the benefits.
Tea is the second most consumed beverage in the world. Water is first.
Hypertension, or high blood pressure, is the most common form of heart disease and affects about 20% of the adult population in many countries. The condition is associated with stroke, heart failure, and kidney dysfunction and is a major risk factor for heart-related death.
“A link between tea drinking and blood pressure reduction has been postulated for decades in general health care in Chinese populations,” write researcher Yi-Ching Yan, MD, MPH, of the medical college of National Cheng Kung University in Taiwan, and colleagues.
But researchers say few studies have examined the long-term effects of tea drinking on the risk of hypertension, and the results so far have been conflicting. They say this study is the first on the issue to use a large number of people and detailed information about tea consumption and other lifestyle and dietary factors associated with hypertension risk.
Do Coffee And Tea Influence Your Blood Pressure
The daily high intake of caffeine has been associated with the increase in CVD risk factors. However, the long-term moderate intake of coffee or tea does not have any detrimental effect on healthy individuals. In fact, an epidemiological data suggests that black and green tea may reduce the risk of both coronary heart disease and stroke by between 10% and 20%.3
So, what is responsible for the CVD protection exerted by these beverages? Research studies are not yet able to identify the compounds which are capable of it. One factor could be the phytochemicals in them, which may influence the endothelial function, resulting in vascular relaxation. The improved glucose metabolism or the inhibition of oxidative stress may also contribute to it.4 The direct effect of tea components on endothelial-dependent vasodilation, which increases the blood flow, thus, reducing blood pressure, has also been suggested in another study.5
The 2015 edition of Dietary Guidelines for Americans came out with a good news for coffee lovers. According to their recommendations, the consumption of coffee within the moderate range is not associated with increased long-term health risks among healthy individuals.6 Moreover, they point out that consistent evidence relates coffee consumption to reduced risk of cardiovascular disease in healthy people.7 But, the exact causes behind these benefits are still not proven. It could be either caffeine or any other compound present in the coffee.

During a clinic visit, all participants completed a questionnaire, which collected information about age, smoking history, physical activity and residential postal code. Weight and height were measured, and the BMI was calculated in kg/m2. Smoking status was coded into nonsmoker, ex-smoker and current smoker. For physical activity, the women filled in a questionnaire that included the following question: Do you participate in any sports recreation or regular physical activity? Those who answered yes to this question were asked to list up to four activities and the duration that they engaged in each activity. Women who answered no to the activity question were classified as being sedentary and scored zero for activity. Activity levels in the active women were calculated in kJ/d using published energy costs of listed activities. Socioeconomic status was assessed using relative social advantage according to residential postal codes. This variable was divided into two levels: high and medium-to-low advantage.
What Is The History Of Tea
The story of the origin and history of tea is traced back to the evergreen shrub of East Asia. According to legends, tea has been known and consumed in China since about 2700 BCE.
Tea became a part of China where it served as a medicinal beverage obtained by boiling the fresh leaves in water. As time went on, tea became a daily drink this prompted the cultivation and processing of tea to rise at a very high rate.
The Dutch East India Company carried the first consignment of Chinese tea to Europe in 1610.
Then in 1669, the English East India Company brought China tea from ports in java to London market.
Then by the late 19th and early 20th centuries, tea-growing had extended to Russian Georgia, Sumatra, Iran and then to non-Asian countries.

Green Tea May Help You Lose Weight
A review of studies suggested that green tea and green tea extract may help lower blood glucose levels and may play a role in helping prevent type 2 diabetes and obesity.
A study mentioned in the review found that people who drank green tea habitually for more than 10 years had lower body fat and a smaller waist circumference than those who did not. And obesity can raise a persons risk of developing type 2 diabetes by at least sixfold, according to a study published in April 2020 in the journal Diabetologia.
One of the reasons green tea may play a role preventing diabetes? It contains a potent compound called epigallocatechin gallate . EGCG has been found to increase the uptake of glucose into muscle cells, says Palinski-Wade. According to a review published in February 2019 in the International Journal of Molecular Science, this process of EGCG stimulating glucose to enter muscle cells may also be useful to treat obesity.
Per the U.S. Department of Agriculture , one cup of green tea has 0 carbohydrates, 0 grams of sugar or fat, and a mere 2.4 calories, making it an all-around healthy choice.
