Green tea, from the Camellia sinensis plant, has been revered for centuries for its medicinal properties,” says Retelny. A moderate intake of caffeine shouldn’t be a problem to your heart health, but some people, especially children, are more sensitive than others to its effects. Energy drinks are also not recommended for pregnant or breastfeeding women and children. In March 2018, UK supermarkets decided to stop selling them to children under 16.

Epidemiological and intervention studies provide evidence that consumption of tea and other polyphenol-containing foods lower blood pressure. In a large epidemiological study involving over 20,000 Norwegian participants, systolic blood pressure was 2.1 and 3.5 mmHg lower in men and women, respectively, who consumed five or more cups of tea per day [ 12]. In a study of 218 elderly women, tea consumption and urine 4-O-methylgallic acid (a measure of polyphenol consumption) correlated inversely with systolic and diastolic blood pressure, with a 2.2 mmHg lower systolic blood pressure for each cup of tea consumed [ 28]. While these absolute changes in blood pressure may seem small, changes of this magnitude on a population basis would result in the prevention of many cardiovascular events and strokes [ 29]. Yang and colleagues examined incident hypertension in a cohort of 1,507 men and women in Taiwan and observed a reduction in the risk of developing new hypertension in individuals consuming more than 120 ml of green or oolong tea per day after adjusting for other risk factors, lifestyle, sodium intake, and coffee consumption [ 30]. On the other hand several very large studies have shown no relation between tea consumption and blood pressure [ 31– 33].People who are sensitive to caffeine could experience insomnia, anxiety, irritability, or an upset stomach when consuming tea in large quantities. Tonic water might sound innocent, but like other carbonated drinks and mixers, it can be high in sugar, unless you chose “slimline” or “diet” versions. A standard serving of tonic water is often smaller, which might mean that you might drink less sugar per portion, but for the same portion size, it’s comparable to other sugary fizzy drinks (7.4g sugar per 150ml can).

In vitro protective effects of colon-available extract of Camellia sinensis (tea) against hydrogen peroxide and beta-amyloid (Aβ((1-42))) induced cytotoxicity in differentiated PC12 cells [Abstract].

For instance, one study found that EGCG may break up and dissolve potentially dangerous protein plaques found in the blood vessels, and thus may lower the odds of someone developing atherosclerosis (the buildup of material in the arteries that can reduce blood flow to the heart and brain). Atherosclerosis is a risk factor for stroke, per the American Stroke Association. What isn’t debatable is that drinking plain tea is healthy for your heart and weight loss–friendly because it doesn’t have sodium or calories, according to the Harvard T.H. Chan School of Public Health. Several epidemiological studies failed to show an association between tea consumption and cardiovascular disease. For example, in the Scottish Heart Health Study involving 10,359 men and women there was no association between tea consumption and prevalent coronary heart disease [ 13]. In a cohort of 1,900 Welsh men, the group with the highest consumption of tea (more than eight cups per day) actually had higher ischemic heart disease mortality compared to the group consuming less than two cups per day [ 14]. The authors pointed out that tea is often consumed with milk in the United Kingdom and speculated that milk might have affected absorption or increased fat intake and influenced a benefit of tea. Bear in mind that adding milkand cream will add fat and calories. If you like your drink with milk, use low-fat milk – semi-skimmed, 1% or skimmed. One review of well-designed studies looked at the effects of drinking tea on blood pressure in people with hypertension, or high blood pressure.Atherosclerosis refers to a buildup of plaque in the walls of arteries. This can lead to coronary heart disease, stroke, and chronic kidney disease. Free radicals can contribute to this condition. Khalaf MHG, Chowdhary S, Elmunzer BJ, et al.

It strengthens arteries and helps to build blood and it regulates your overall heart function. If green tea is a little too mild for you, consider giving oolong a try — because of the extra oxidization, it has a more robust flavor.
